科目:高中英語 來源:2010—2011學(xué)年福建省安溪一中、惠安一中、養(yǎng)正中學(xué)高二下期末聯(lián)考英語卷 題型:閱讀理解

A popular saying goes, “Sticks and stone may break my bones, but words will never hurt me.” However, that’s not really true. Words have the power to build us up or tear us down. It doesn’t matter if the words come from someone else or ourselves – the positive and negative effects are just as lasting.
We all talk to ourselves sometimes. We’re usually too embarrassed to admit it, though. But we really shouldn’t be, because more and more experts believe talking to ourselves out loud is a healthy habit.
This “self-talk” helps us motivate ourselves, remember things, solves problems, and calm ourselves down. Beware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying, “Good job!”
Words possess power because of their lasting effects. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it true? Is it loving? Is it needed? If what we want to say doesn’t pass this test, then it’s better left unsaid.
Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem(自尊) and motive others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.
【小題1】The author argues in the first paragraph that ________.

A.words will never hurt us at all
B.words have lasting effects on us
C.positive effects last longer than negative effects
D.negative words last longer than positive effects
【小題2】Why should we not feel embarrassed when talking to ourselves?
A.Almost everybody has the habit of talking to oneself.
B.It does harm to have “self-talk” when we are alone.
C.Talking to ourselves helps us to solve all the problems.
D.Talking to ourselves is believed to be good for our health.
【小題3】The underlined phrase “give ourselves a pat on the back” in Paragraph 3 means _________.
A.blame ourselvesB.punish ourselves
C.praise ourselvesD.talk to ourselves
【小題4】Which of the following statements would the author agree to?
A.It is better to think twice before talking to others.
B.It is impossible for unkind words to be forgotten.
C.Words always possess long positive effects.
D.Kind words are sometimes not needed at all.

Is it true that cats have nine lives? One 4-year-old American cat named Sugar definitely seems to have more than one. Sugar fell from the 19th floor of her owner’s home in Boston last month and was only hurt a little on her chest.
“This story isn’t much of a surprise,” said Jake Socha, a scientist at Virginia Tech University, US, in an interview with the BBC. “There have been lots of records of these cats surviving.”
Back in 1987, scientists studied 132 cats. All of them had been brought to a vet’s clinic in New York after falling from tall buildings. Around 90 percent of these cats were alive after their fall and only 37 percent had been seriously injured.
“Being able to survive falls is a critical thing for animals that live in trees, and cats are one of them,” said Socha.
Cats have developed special body structures to survive accidental falls. Their legs are muscular. This can protect their bones from breaking, Professor Andrew Biewener from Harvard University told the BBC. Cats can also spread out their legs like a parachute to reduce their falling speed, he said.
The strange part, according to scientists, is that cats have a better chance of survival if they fall from higher than seven stories. This is because cats have a good sense of which way is down. They can twist their bodies as they fall to make sure they land on their feet. A higher fall means more time for the cat to change its body position.
However, you should not throw your cat out of the window to see how this works. Most pet cats are overweight nowadays. They are not fit enough to change their position in midair, warned Steve Dale, an American cat behavior scientist.
“This cat (Sugar) was lucky,” Dale said. In fact, most cats would suffer serious lung damage, a broken leg or a broken jaw or teeth damage, he said.
【小題1】What can we learn from Paragraph 3?

A.Cats really do have nine lives.
B.Many cats can survive falls.
C.Cats are the softest animals in the world.
D.More than half of the cats that fall from high places end up badly injured.
【小題2】What does the underlined word “critical” mean in the context?
A.Important.B.Easy.C.Challenging. D.Serious.
【小題3】Why can cats survive falls according to the article?
a. They have a hidden parachute in their bodies.
b. Their legs have developed in a way that protects their bones from breaking.
c. They can land on their feet.
d. They can twist their bodies to reduce the speed at which they are falling.
A.a(chǎn), bB.b, cC.c, dD.b, d
【小題4】Which of the following statements is TRUE?
A.A pet cat that falls out of a tall building is not really at risk.
B.Sugar was lucky that she was only injured in the leg.
C.Cats are confused as to which way is down when they are in midair.
D.A cat that falls from the fourth story of a building is more likely to die than one that falls from the 10th story.

A popular saying goes,“Sticks and stones may break my bones,but words will never hurt me.”However,that's not really true.Words have the power to build us up or tear us down.It doesn't matter whether the words come from someone else or ourselves—the positive and negative effects are just as lasting.

We all talk to ourselves sometimes.We're usually too embarrassed to admit it,though.In fact,we really shouldn't be because more and more experts believe talking to ourselves out loud is a healthy habit.

This“self—talk”helps us motivate ourselves,remember things,solve problems,and calm ourselves down.Be aware, though,that as much as 77%of self—talk tends to be negative.So in order to stay positive,we should only speak words of encouragement to ourselves.We should also be quick to give ourselves a pat on the back .The next time you finish a project,do well in a test,or finally clean your room,join me in saying“Good job!”

Often,words come out of our mouths without us thinking about the effect they will have.But we should be aware that our words cause certain responses in others.For example,when returning an item to a store,we might use warm,friendly language during the exchange.And the clerk will probably respond in a similar manner.Or unkind and critical language will most likely cause the clerk to be defensive.

Words possess power because of their lasting effect.Many of us regret something we once said.And we remember unkind words said to us! Before speaking,we should always ask ourselves:Is it true? Is it loving? Is it needed? If what we want to say doesn't pass this test,then it's better left unsaid.
