“We expected our first child to be
perfect．”How many parents have said，or at least
thought，those words? Most likely every single one．
1 know that's what I 31 with our oldest son, Joe．He was always a 32 kid．He wasn't
the kind of boy who 33 snowballs at passing cars on a cold
winter day or who 34 water balloons on the mail carrier from
an upstairs window during hot August． 35 he wasn't perfect．From the day Joe stated kindergarten，he 36 一with maths．Always maths．While he passed each grade，it was never with flying colors，and he was 37 at the top of his class．How I 38 friends who had children with the “maths
gene"．1 don't know how many times I 39 while listening to another mom telling me
that her daughter was doing high school algebra while in sixth grade．
After hearing one of these
stories―and there were so 40 of them over the years―I 41 hang up the telephone and look over
at Joe―who would be happily playing a video game，drawing a
picture，or simply 42 a warm spring day―and 43 why we didn’t raise a maths genius．How is he ever going to get in to college if he doesn't get 44 at maths?
Needless to say,my worries
never really amounted to much．Moms 45 to worry and worry ,while whatever they
are worrying about usually disappears on its own or is quickly replaced by
another 46 ．
During high school，Joe slowly improved at maths．He 47
algebra I，geometry and algebra II，our state requirements for maths．One day he
said to me：“I would be taking pre-calculus(學(xué)習(xí)微積分前必修課程)in
my last year of high school. I want to do really well in college．Mom，I know it will be hard but I think it’s 48 that I try to do my best．”
No，my oldest son wasn't perfect．He wasn't a
maths genius，either．But he knew what was important：he was
focusing oil his future while 1 was worrying over his 49 Joe was trying to do his best even when
he knew how hard that was going to be．And that, to
me, is even better than being 50

第三部分：閱讀理解（共20小題；每小題2分，滿分40分）
閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項，并在答題卡上將該項涂黑。
A
Advertising actually has a dual（雙重的）function：to sell，as well as to inform．If you stop to think of it，advertisements（ads）provide
information of almost everything in our household and immediate environment，from shampoo to fuel for ears．An obvious purpose is to inform
consumers of new products and services as well as to remind them of established
ones．Performance，price，value for money，quality and reliability are some of the main features mentioned in
ads．
Yet there is another important side of advertising that should not
be forgotten：choice．A number of ads for different
brands of the same product，e．g．toothpaste，shampoo or washing powder allow the
consumer to choose．Choice is an important part of buying．
In this busy day and age，there is little time for comparison shopping．To determine which product is the
best to buy，arid at the
most competitive price，consumers these days rely on advertising in its various forms．This saves time arid energy and
makes shopping easier．
Few can deny that ads benefit the consumer since they encourage
healthy competition．When companies compete for the consumer’s dollar, this is good for
the purchaser of the product or service．Advertising tends to increase competition since it informs consumers
of what is available．One company’s offer will be either matched or bettered by another
company in its advertising．
It was unheard of ten years ago to buy products directly using a
personal computer，but it has
become a matter of course for some people to browse（瀏覽）the Internet，surf until they find an e-commerce
site and then select the product. Marketing products has been almost turned
upside down by new ways of selling and buying. More than at any time in
history, the choice of goods is unlimited. The whole world is a customer’s
markerplace. For busy people like you and me, advertisements actually do us a
favor.
51．What the writer of this passage
wants to tell US most is that .
A．a(chǎn)dvertisements
benefit busy people in many ways
B．a(chǎn)dvertisements encourage more
business competitions
C．a(chǎn)dvertisements provide main
features of new products
D．selling and informing are two
functions of advertising
52．Which is least discussed in the
passage as one of the important sides of advertising?
A．To inform
consumers of new products and services．
B．To provide
consumers with chances to choose．
C．To increase
healthy competition of companies．
D．To change the
way of selling and buying．
53．The “comparison shopping” refers to
the behavior of ．
A．comparing and
buying a product at the lowest price
B．comparing and
deciding which is the best to buy
C．relying on
advertising and simplifying shopping
D．buying a
product at least competitive price
54．Healthy competition benefits
consumers because ．
A．it helps
companies to compete for the market
B．it gets
companies to improve their services
C．it provides
them with the best products and services
D．it gives them
many chances to choose their products
B
Dinner was almost ready when the killing occurred．When Don Wise wandered into the
living room of his home，his ten-year-old son，Mike，and a
12-year-old friend were sitting in front of a large-screen television set．They were playing a video game they
had rented called Goldeneye 007，one of the top-selling titles of 2007．
Standing behind the boys，Wise saw that one boy pushed the button and shot the character in
the face．Blood
splattered（噴濺）the lab
coat of the character as he circled and fell．“You’re down!” the boy said，laughing．
Frightened by the child’s obvious fun．Wise ordered the boys to turn the game off．“This game is terrible，”he said seriously．“I don’t want you to play with this
any more．”
Video games have become a pervasive form of entertainment
since the 1990s．Today an
estimated 69 percent of American families own or rent video and computer games．Most are harmless entertainment，but in far too many of the most
popular ones，kids are
acting out realistic violent experiences on their TV and computer screens．“These are not just games any more，”says Rick Dyer，president of the San Diego-based
Virtual Image Productions and an outspoken critic of titles with violent and
sexual content．“These are
learning machines．We’re
teaching kids in the most incredible manner what it’s like to pull the trigger（扳機(jī)）．The focus is on the thrill，enjoyment and reward．What they’re not realizing are the
real life consequences．”
Such video games introduce kids to a fantasy world that features
amazingly lifelike characters，detailed images of brutality（野蠻），and an audio mix of heart-pounding music，stereo sound effects and realistic
voices．Unlike movies
and television，where you
watch the violence，the vedio game lets you feel the sensation of taking violent actions．When you’re into the game，you’re in the game．
“The technology is becoming more engaging for kids，”says David Walsh，president of the National Institute
on Media and the Family（NIMF），a watchdog
group in Minneapolis，“and a part of the games features anti-social themes of violence，sex and rude language．Unfortunately，it’s a part that seems particularly
popular with kids between ages 8 to 15．”
55．Which of the following best
summarizes the main idea of this passage?
A．Video game
Violence is very harmful to kids．
B．Video game is
a common form of entertainment．
C．Video game
violence is popular with children．
D．Video game is
the reflection of the real life violence．
56．We can infer from the passage that
the
．
A．NIMF is
characteristic for its social justice
B．NIMF is a
political organization in Minneapolis
C．NIMF promotes
video games and other media products
D．NIMF detects
the media industry’s illegal actions
57．The underlined word “pervasive”
in Paragraph 4 most probably means ．
A．worldwide B．instructive C．widespread D．harmful
58．Which of the following statements
would Rick Dyer agree with?
A．Video games
with some violence teach kids to experience real life．
B．Video games
are realistic ways to learn more about the real-life world．
C．Video games
with fantastic features are loved by most kids in the US．
D．Violence and
sex content video games have a negative influence on children．
C
What will we be eating in the future? Here are the top factors that
will be affecting the food that ends up on our tables in the new century．
Genetically engineered
food
Many crops are already genetically engineered，often to produce more food，fight against pests or improve
nutrition．But concern
is growing over the lasting effects of changing nature．While existing research has found
little harm in genetic engineering，a recent study found the flower powder of a genetically engineered
corn can kill the normal butterfly．This finding made many people nervous and brought attention to the
topic．
Dining out Americans are
increasingly eating meals away from home，both in sit-down restaurants and in fast food outlets．In the last decade alone there was
a 14 percent decrease in the number of meals eaten at home．At the same time，restaurants are just beginning to
really open their doors on the Internet．Websites exist to make restaurant reservations（預(yù)約），view menus，and get tips from your favorite
chefs．The dining
out trend and the demand for high-quality，chef-prepared food have encouraged chefs to spend time out of the
kitchen――teaching classes，appearing on TV，and writing cookbooks．
Eating in Eating in doesn’t
always mean cooking．Ready-made meals and frozen food sold in supermarkets taste better
all the time．Restaurants
are offering neatly packaged “food to go”，and meals can be ordered over the Internet．Cooking is not as much as a
necessity，as it is a
hobby，a special
treat．Home cooks
are looking to more than just mom’s food，and want to make food they try in restaurants．
Agriculture Although American
farmers have been hit hard recently by bad weather, low prices and decreasing
government help，they can
increase grain production not using old farm methods．
59．Which of the following is the main
reason for genetically engineered crops?
A．To lead to
more food and better nutrition．
B．To kill the
normal butterfly．
C．To reduce the
harm done by insects．
D．To change the
nature of the crops．
60．From the passage，we learn that ．
A．eating out is
not popular among the old people in USA
B．it is now
easier for people to get information about eating out
C．it is popular
for restaurants to send out information on the Internet
D．the trend of
eating out is causing many chefs to give up their jobs
61．In the future，cooking at home will probably ．
A．still be the
job of most housewives
B．take up most
of people’s free time
C．bring much
joy to more people
D．Lead to many
restaurants closing down
62．According to the passage，farmers should to get
a higher grain production．
A．turn to
better farming methods
B．a(chǎn)sk for the
support of the government
C．raise the
prices of crops
D．not care
about the effects of bad weather
D
A train sped up through the countryside at 60 mph as a “traveller” relaxes with his
newspaper．But this is
no businessman taking it easy――the driver of the passenger express（快車）is doing the reading．
A Sunday Express reader caught this Virgin employee on film as the
train sped through Derbyshire on its way to Plymouth from Newcastle．
Virgin，which has
come under repeated criticism over their rail service，yesterday fired the driver after
being shown the photograph．A spokesman said an inquiry（調(diào)查）was under way to make sure exactly what he was doing and why he
appeared to have taken his eyes off the track ahead.
The picture comes in the week that the public inquiry into the
Southall rail disaster, which claimed seven lives, heard that the driver at the
centre of that case had earlier been spotted with his feet on the control
button of his cab.
Larry Harrison, who worked for Great Western Trains, drove through two
warning signals before crashing at 60 mph
into a waiting train.
The reader who took this picture was standing on a bridge outside Chesterfield early one
summer's evening. He said: "I only realised what I’d got when I had the
pictures developed. I couldn't believe it."
"As far as I could see, there was no one else in the cab with
the driver, unless they were hiding. The person with the paper open was
certainly sitting in the driver's normal seat."
The photographer works on the railways and does not want to be
named, but he added: "I've seen many drivers with their feet on the
control panel but I've never seen them reading papers like this. There is an
automatic warning system and driver's safety device which reminds him when he
passes yellow and red signals. But you should never take your eyes off the
track and rely only on sounds because you could have unexpected objects on the
line or suddenly have speed limits given."
63. Who is the
"traveller" mentioned in the first paragraph?
A．A train
driver. B．A businessman.
C．A
passenger. D．A newspaper reader.
64. The train
when the picture was taken.
A．was driving
to Plymouth
B．was ready for a picture
C．had seven
people on it
D．crashed into another train
65. Who took the
picture of the driver of the passenger express?
A．A
professional photographer.
B．A newspaper reporter.
C．Another train
driver.
D．A member of the railway staff.
66. According to
what we have read, we may find this passage most probably
A．a(chǎn)t a train
station
B．from a news report
C．from a
driver's safety guide
D．from the police inquiry
E
Managers of most businesses want high profits in order to pay high
dividends（紅利）to their
investors. For this reason, they aim to keep costs as low as possible. They
also want to set high prices to gain high returns. But competition within the
industry often prevents them from doing so. Generally, a business will not
increase the price of its output if its competitors will not increase their
prices. If a business sets its prices higher than those of its competitors,
many of its customers will buy the output of its competitors.
An important decision managers make is their choice of the input-mix
in what combination of capital（資本）, labor, and raw materials to use in production. The goal is to keep
production costs as low as possible. If labor costs are high, for example, a
firm may spend money in automatic machinery so that fewer workers are needed to
complete the same task. If labor is cheap, the company may decide to employ
extra workers instead of buying a machine ~to do the job. The combination of
inputs that permits a firm to produce its goods or services at the lowest
possible cost without reducing quality is called the most productive
input-mix.
The goal of keeping production costs low also affects a company's
choice of location. The resources an industry needs and the customers it serves
are rarely close to each other. As a result, a business must transport inputs,
outputs, or both. A business also tries to keep transportation costs as low as
possible.
Transportation costs are based on weight as well as on distance. The
location a company selects may thus depend on whether the company's product is
heavier or lighter than the materials used to make it. The soft drink industry,
which adds water to other ingredients to make its products, is an example of an
industry that produces weight-gaining products. Soft drink companies choose
locations near their customers. The paper industry is an example of industries
that produce weight-losing products. Many such industries are near sources of
raw materials.
67. What do
businesses choose to do about the prices of their products in competition?
A．To set higher
prices. B．To leave the prices unchanged.
C．To offer
lower prices.
D．To keep the prices adjustable.
68. The underlined
phrase "the most productive input-mix" means mixing inputs
A．with goods or
services sold at the lowest possible prices
B．by selling
goods or services at the lowest possible prices
C．to produce
goods or services at the lowest possible cost
D．to produce
quality goods or services at the lowest possible cost
69. Why is a
company usually very careful about choosing its location?
A．Because the
materials it needs are rather far away.
B．Because the
customers it serves are not so close.
C．Because
transportation costs and the distance are closely related.
D．Because both
production and transportation costs are very high.
70. The soft drink
industry and the paper making industry are used as examples because
A．they share a
lot of things in common
B．they are both
only making lower profits
C．the
transportion costs of their products are the same
D．they are
quite different when considering the locations

79．in which people were eaten 80．With time going by
One possible version：
Every year after the college entrance
exam,the top-rated exam takers will attract wide attention from all over the
country．They accept
various interviews．take part in different social activities and receive quite a lot of
prize money as well．
Some people
say"yes"to this phenomenon． They think,for one thing,it can make more people care about
education;for another,those top studends can and do set good examples to the
rest of the students．
However,others hold opposite
opinions about this,they believe that giving too
much attention to
those top winners can do more harm than good to them． Meanwhile,high marks don’t
necessarily mean strong ability．
In my opinion，it’s all right to give proper
attention to those top winners,but weshouldn't pay too much attention to them．After all,exams and marks aren't
everything．
