Summer is a busy time for travel. For years, people have wondered whether they are safe from viruses when they travel in small, enclosed areas. They worry about close contact with others who may be sick.

The current spread of a swine flu(豬流感) virus has added to these concerns. Recently, the World Health Organization raised its warning about the new H1N1 virus to its highest level. W.H.O. Director-General Margaret Chan declared the sickness a pandemic–a disease that has spread to many nations. Given this information, many people want to know how safe it is to travel?

The answers people are getting may seem conflicting. For example, a W.H.O. statement urged nations not to close their borders or limit trade and travel. Director-General Chan said cases are generally not that serious for most people. Still, W.H.O. officials continue to report new cases across the world.

In the past, the W.H.O. and experts noted guidance for disease spread on airplanes. The experts said you could get infected only if you sit within two rows of someone who is sick. That would be a distance of up to three meters from the sick person. And this was true only if you sat there for more than eight hours.

But a travel-health expert says this guidance may not be helpful for swine flu. He suggests steps that could help prevent getting swine flu on an airplane. His advice includes keeping the airflow over your seat on the “l(fā)ow” position. The doctor says you should point the equipment so the flow of air is just in front of your face.

Doctors say anyone with pain, swelling(腫脹) or red skin on a leg during or after a long trip may have a blood clot(凝塊). Anyone with such signs should see a doctor as soon as possible. The condition many times can be treated with drugs that thin the blood and stop the clot from moving through the body.

68．The underlined word “conflicting” is closest in meaning to ________.

A. in disagreement        B. not true                           C. the same                          D. unbelievable

69．According to Director-General Chan, the swine flu is ________.

A. a disease spread on airplanes                                B. a very dangerous disease

C. a disease requiring limit travel                              D. a widely spread disease

70．Which of the following is the travel-health expert’s opinion on traveling in an airplane?

A. It’s safe to sit within two rows of a sick person.

B. It’s helpful to keep air flowing right before your face.

C. It’s important for a passenger to stay in a plane within 8 hours.

D. It’s certain that a passenger will have a blood clot after a long flight.

71．What would be the best title for the text?

A. Stop Traveling in Case of Swine Flu                  B. Experts’ Arguments Over Swine Flu

C. Prevention of Swine Flu on the Trip                   D. No News Is the Best News

  Pulling heavy suitcases all day in the summer is hard work, especially when you’re a thin 14-year-old. That was me in 1940—the youngest and smallest baggage boy at New York City’s Pennsylvania Railway Station.

   After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I’d like to join them, thinking, “Everyone else is doing it.”

   When I got home that night, I told my dad what I wanted to do. “You give an honest day’s work,” he said, looking at me straight in the eye. “They’re paying you. If they want to do that, you let them do that.”

   I followed my dad’s advice for the rest of that summer and have lived by his words ever since.

   Of all the jobs I’ve had, it was my experience at Pennsylvania. Railway Service that has stuck with me. Now I teach my players to have respect for other people and their possessions. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he’d be gone.

   Whether you’re on a sports team, in an office or a member of a family, if you can’t trust one another, there’s going to be trouble.

What can be inferred about the baggage boys?

   A. They could earn much, but they had to work hard.

   B. Many of them earned money in a dishonest way.

   C. They were all from poor families.

   D. They were all thin, young boys.

What does the father’s advice imply?

   A. It is wrong to give more pay to the passengers.

   B. Don’t believe them if they are paying you more.

   C. Don’t follow others to overcharge the passengers.

   D. It is difficult to work hard and live as an honest boy.

The writer can’t put up with stealing because he thinks that ___.

   A. it is a totally shared experience

   B. it is considered as the most dangerous

   C. it does great harm to human relationship

   D. it may lead to the loss of his sports team

It can be concluded from the text that ___.

   A. his father’s advice helped him to decide which job to take up

   B. working in the sports team was his most important experience

   C. he learnt much from his shared experience with his team members

   D. his experience as a baggage boy had a great influence on his latter life

They say that Mexico is a country no one ever leaves. Every year, millions of tourists pass through. And Mexicans happily warn that a part of them will remain behind forever. Most visitors are vacationing North Americans who go up on the brilliant beaches of Cancun, Acapulco, Mazatlan, and Puerto Vallarta. The beaches, of course, are among the world’s best ----but those who venture (冒險(xiǎn)) inland are rewarded with the true soul of Mexico.
And it is a big soul. The Republic of Mexico is vast, consisting of nearly two million square miles of coastline, desert, rain forest, mountains, and rich plains. From the American borderlands of the wide, agriculturally rich north, the country narrows gently as it sweeps south and east. The two main mountain ranges(山脊), the Sierra Madre Occidental and the Sierra Madre Oriental, hug the west and east, finally merging（融入） into the volcanically active central highlands and the capital, Mexico City - the most populous city in the world. Further south, the country narrows to only 100 miles, then broadens again before reaching the Guatemalan border. There are two major peninsulas (半島) in Mexico: the Baja Peninsula to the west and the Yucatan peninsular to the east.
The population is about 106 million. and the generosity (慷慨大方) of the Mexican people is unsurpassed. Knowing a few simple sentences in Spanish will win hearts.
Mexico has been blessed with an unusually temperate (適度的) climate year-round. The most important thing to remember is that the Mexican summer is also the rainy season, although the rain rarely lasts more than a few hours, and typically arrives in the late afternoon. Extremes(極端)are present only in the North and in Baja, both of which have deserts where the temperature leaps above 100F. Mexico City has a year-round temperature in the high 80s. while the coasts usually stay in the mid-90s. Night time temperatures fall somewhat, but rarely break down below a comfortable 60F.

B
“It was all his own idea, ” says Pat Peters, the 38-year-old wife of Palo Alto, California high school football coach Bob Peters, 39. Bob had just drawn up a “motherhood contract” --a document stating that for 70 days this summer he would take over the care and feeding of the couple’s four children, plus all household chores. Although he didn’t even know how to make coffee when he signed, he was quite confident.(He thought the experience would make a nice book.)
After 40 of the 70 days, he was ready to give up. “I was beaten down, completely humbled（挫敗的）,”  admits Peters. Three weeks later he spoke to the local press, stating, “Not only is motherhood a difficult task, not only is it never-ending, it is an impossible job for any normal human being.”
Bob and Pat were high school sweethearts. After they were married in 1960, she worked as a secretary to help put him through university. Since then Bob has been the football and wrestling coach at Palo Alto’s Cubberley High while Pat raised the kids. Then two years ago Pat went back to work as a secretary at Cubberley. “I had been around children so much,” she sighs, “I couldn’t talk to a grown-up.” She continued to run the household, however----until Bob signed the contract, therefore, she decided to relax and enjoy it. 
Although Peters had consulted(咨詢) with his school’s home economics teachers and the head of the cafeteria, his meals were sometimes a disaster. “I tried to slip the butter I’d forgotten under the eggs after they were frying, ” he says. For the last three weeks, the family ate out a lot—sometimes having Macdonald’s hamburgers for lunch and dinner.
As for housekeeping, a home economics teacher had told Bob that a room always looks clean if the bed is made. “I found an easier way-I shut the doors, ” he says. Soon the kids were wearing the same clothes for a week. “I made them wear their shirts inside out, and when we went to pick up Pat at work they turned them right side out so they would look clean.”
Now that Bob has publicly admitted he was wrong, he is routinely sharing the child-raising and household tasks with Pat. The tentative（暫時(shí)的） title of his book about the summer is taken from something he shouted at the kids one day.
45. The couple signed the contract because _______.
A. Pat complained a lot about her doing the housework all by herself
B. Bob loved taking care of children and wanted his wife to have a good rest
C. they agreed that husband and wife should share household tasks
D. Bob thought it easy to take care of the family and wanted the experience for a book
46. It was agreed that if Bob failed to keep to the contract, he would have to _______.
A. pay a certain amount of money
B.  admit publicly he was wrong about motherhood 
C. say sorry to his wife         D. do all the housework for years
47. What can we learn about Pat Peters?
A. She was hard-working and selfless.   B. She was pretty and kind-hearted.
C. She was tired of the child-raising and household tasks.
D. She did not love Bob any longer.
48. Which of the following can best end the news story?
A. “Wait till your mother gets home!”    B. “My experience of being a mother.”
C. “I’m proud of you all, my dear!”     D. “Motherhood: an impossible job for anyone.”

Few Americans remain in one position or one place for a lifetime. We move from town to city to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where we raise our children to the home where we plan to live in retirement. With each move we are forever making new friends, who become part of our new life at that time.

For many of us summer is a special time for forming new friendships. Today millions of Americans vacation abroad, and they go not only to see new sights but also with the hope of meeting new people. No one really expects a vacation trip to produce a close friend, but the beginning of a friendship is possible.

We often hear the phrase: "You've a greater chance of being struck by lightning." It is used to describe something that hasn't got much chance of happening. However, the common saying undermines(掩蓋) the very real dangers of lightning.

Last Friday, at least 5 people were killed by lightning in Nepal(尼泊爾).

Lightning strikes are the second most common cause of deaths during natural disasters in the US. The first is floods. Around 400 people nationwide are struck by lightning each year, and of those, 73 people die. There are more people killed by lightning than by tornadoes and hurricanes.

Because lightning kills only one or two people at a time, its danger does not receive as much attention as other disasters.

So to raise awareness, the US has made June 22-28 National Lightning Safety Week. It aims to warn the public of the dangers of lightning and provide safety tips during thunderstorms.

"If you hear thunder, you are in danger of lightning," said Rocky Lopes, a disaster educator at the American Red Cross.

"Thunder means that lightning is close enough to hit you at any minute, so you should move indoors immediately and stay there until after the storm has ended. The single most important thing to remember is to seek a hiding place," Lopes said.

Summer is the high time for lightning storms, so when lightning strikes across the sky, remember these safety tips:

Stop working, fishing, swimming or playing in open fields.

If you can count less than ten seconds between a thunder and a lightning flash, take cover inside the nearest building.

Do not stand under a tree.

Get off bicycles or motorcycles.

Crouch down(蹲下)if there is no hiding place.

Avoid open spaces, wire fences, metal objects and electrical objects such as hair driers.

 

1.  The popular opinion about being struck by lightening is that ______.

A. there’s a greater chance for being killed by lightening than any other natural disaster

B. it is the most dangerous among all the natural disasters

  D. it is impossible for people to be killed by lightening

2.The average death rate of being struck by lightening in US is about _______.

  A.18%　　　　　B.50%　　　　　  C. 30%　　　　  D. 73%

3.thunder in             the open air______.

A. just stand by your bicycles and motorcycles

  B. quickly find a place to go inside

  C. count ten seconds between a thunder and a lightening

  D. don’t have a hair drier in your hand

4.According to the passage, which of the following is TRUE?

A. There are more people killed by tornadoes and hurricanes than by lightening in US each year.

B. There are on average 5 persons killed by lightening in Nepal each day.

C. The death rate of being stuck by lightening is much higher than by other natural disasters.

D. The National Lightening Safety Week is made to warn the public against the lightening.
