    Some people surveyed tasted the sweet, salty, and crunchy together with other tastes of food as they listen to different noises. It shows that louder noises reduced the reported sweetness or saltiness of food while increasing the measure of crunchiness(松脆).

    It may go some way to explain why airline food is widely complained about by both the workers and passengers. Andy Woods, a researcher, said, “It’s a general opinion that plane foods aren’t fantastic, but I’m sure airlines do their best, so we wondered if there were other reasons. One thought was that perhaps the background noise may have an effect. NASA gives their space explorers very strong-tasting foods, because for some reason, they can’t taste food that strongly—again, it may have something to do with the background noise.”

    In a study, 48 people were fed sweet foods or salty ones, while listening to nothing or noise through earphones. Meanwhile they rated(划分等级) the foods. In noisier settings, foods were rated less salty or sweet than they were when it was silent, but were rated crunchier. “The evidence shows that if the background noise is loud, your attention might be drawn to that, away from the food.” Dr. Woods said.

    “We are still at an early stage of progressing and this is a rather small study to really draw definitive(最完整可靠的) conclusions from,” Dr Woods said, “but they suggest that restaurants could well adapt their choice of food for a given environment.”

    Also in the group’s findings there is the suggestion that the overall satisfaction with the food is also related to the degree to which people like what they are hearing.

    1.How does the food taste when it is eaten in a noisy environment?

    A. Less salty but crunchier.B. Sweeter and saltier.

    C. Sweeter but less crunchy.D. Less sweet and crunchy.

    2.Why does NASA give their space explorers very strong-tasting foods?

    A. Foods become less tasty in space.

    B. The explorers lose their sense of taste in space.

    C. Loud noises in space may weaken the explorers’ sense of taste.

    D. The explorers need tastier foods to keep energetic in space.

    3.We can infer from what Dr. Woods said in the 4th paragraph that ________.

    A. the environment influences the food a restaurant sells

    B. the researchers have made an effective conclusion

    C. music will weaken people’s sense of taste while eating

    D. listening to nothing while eating is the best choice

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

    A. The best dinner environment

    B. How to change plane foods

    C. Listening to music while eating

    D. Background noise affects the taste of foods

    I was not good in math in the first year of junior high school. Having been failed so many times in math exams, I was anxious about the subject. Every time I tried my best work out a math problem and I was afraid of making mistakes, which really made me feel helpless. Unluckily, I met a nice math teacher in a second year. She told me that I did need to worry about making mistakes because I could find out my shortcomings through my mistakes. She always encouraged myself to try again whenever I make a mistake. Thanks to my teacher encouragement, I became interested in math and made rapid progress. My experience proves that failure was the mother of success and that we can learn a lot from our mistakes.

    I always felt sorry for the people in wheelchairs. Some people, old and weak, cannot get around by themselves. Others seem perfectly healthy, dressed in business suits. But whenever I saw someone in a wheelchair, I only saw a disability, not a person.

    Then I fainted (晕倒) at Euro Disney due to low blood pressure. This was the first time I had ever fainted, and my parents said that I must rest for a while after First Aid. I agreed to take it easy but, as I stepped towards the door, I saw my dad pushing a wheelchair in my direction. Feeling color burn my cheeks, I asked him to wheel that thing right back to where he found it.

    I could not believe this was happening to me. Wheelchairs were fine for other people but not for me, as my father wheeled me out into the main street, people immediately began to treat me differently.

    Little kids ran in front of me, forcing my father to stop the wheelchair suddenly. Bitterness set in as I was thrown back and forth. “Stupid kids… they have perfectly good legs. Why can’t they watch where they are going?” I thought. People stared down at me, with pity in their eyes. Then they would look away, maybe because they thought the sooner they forgot me the better.

    “I’m just like you!” I wanted to scream. “The only difference is you’ve got legs, and I have wheels.”

    People in wheelchair are not stupid. They see every look and hear each word. Looking out at the faces, I finally understood: I was once just like them. I treated people in wheelchairs exactly the way they did not want to be treated. I realized it is some of us with two healthy legs who are truly disabled.

    1.The author once _________ when she was healthy.

    A. showed respected to disabled people

    B. looked down upon disabled people

    C. imagined herself sitting in a wheelchair

    2.Facing the wheelchair for the first time, the author _________.

    A. felt curious about it B. got ready to move around in it right away

    C. thought it was ready for her father D. refused to accept it right away

    3.The experience of the author tells us that_________.

    A. life is the best teacher

    B. people often eat their bitter fruit

    C. life is so changeable that nobody can predict

    D. one should never does to others what he would not like others do to him

    4.Which is the best title for this passage?

    A. How to Get Used to Wheelchairs

    B. Wheelchairs Are as Good as Two Legs

    C. People with Two Legs Are Truly Healthy

    D. The Difference Between Healthy People and the Disabled

    Here comes a story that many years ago a man arrived at a village in India to catch monkeys so he could sell them to zoos. The monkeys, however, were very clever and every sort of trap he set failed. A young boy watched the man's pathetic efforts and laughed.

    The man said, “If you can catch me a monkey, I'll give you $ 2.” That was a huge amount of money then.

    The boy went to his home and took a clay pot with a narrow neck. He placed a few nuts around the pot and put lots of nuts inside. He then tied the pot to a tree and told the man, “We should have a rest in a few hours. Let's wait in the village. The monkey will call us when he is ready.”

    Certainly enough, a band of monkeys soon discovered the nuts and the pot. One slipped his hand in the pot and grabbed a handful of nuts, but he couldn't pull his hand out of the narrow opening of the pot because his fist(拳头) was clenched. The monkey feared and started making loud noises. Some of the other monkeys tried unsuccessfully to pull the pot off his hand.

    The boy and the man heard the noises and the boy got a big strong bag. As they approached the monkeys they all ran away except the one with its hand in the pot. The boy grabbed the monkey and the pot. The man was amazed and asked the boy the secret of his monkey trap, “Why was it so easy for the monkey to get his hand in but so hard to get it out?”

    The boy laughed and said, “The monkey could have easily got his hand back out and escaped, but he would have had to let go of the nuts in the pot and he just wasn't willing to let go. They never are.”

    What lessons can be learned from this story? Do people sometimes trap themselves by holding onto things that they should let go? Do you?

    1.What does the underlined word “clenched” in the 4th paragraph probably mean?

    A. quickly pushed B. lightly pulled

    C. tightly fastened D. closely held

    2.Why couldn’t the monkey pull his hand out of the pot? The reason lies in that .

    A. the pot’s neck was too narrow B. the monkey wouldn’t let go of the nuts

    C. the monkey’s fist was too big D. the nuts in the pot were too delicious

    3.Which of the statement is NOT true according to the story?

    A. The boy just played a trick on the man.

    B. The monkeys were too clever to be trapped.

    C. The boy was helpful.

    D. The boy could ask for $2 from the man.

    4.What might be the best title of this passage?

    A. the monkey and the boy B. the boy and the pot

    C. the monkey and the pot D. the man and the pot
