第二部分阅读理解（共两节，满分40分）
第一节（共15小题；每小题2分，满分30分）
A
It is a good time for us to have a successful ice fishing season. Here are some things we should think about.
The first thing to remember is that you needn't be the first person on the ice. Every year someone tries to get out there before the ice is safe. As soon as it's safe，you should be out there.
Early ice is usually thin，and often there is no snow on top of it. That means the fish can see you very easily. Therefore，you need to be quiet. The more you move around，the more you're going to spook the fish. Later in the year when the ice is thick and there's snow cover，you can move around more.
Many of the most successful anglers(钓鱼者)like to fish from a shelter(遮盖物) in the ice fishing season. The fish see the shelter as just a dark object，and the movements of the angler inside it can't be seen. Also，line that is hard to see underwater will be better for ice fishing .Therefore，Fire Line Micro Ice，a new product on the market，is strongly recommended.
Early in the ice fishing season，the water is often quite clear and the fish will usually be in shallow water. This can be a great time to watch the fish. Even if you might not catch many fish on some days，you can learn many things that will help you catch more fish next time out.
Always remember our first reminder. If you remember that，you'll enjoy lots of ice fishing early in the ice fishing season.
21．The purpose of the passage is to ________.
A．warn us not to go ice fishing B．persuade us to buy a new product C．tell us the pleasure of ice fishing D．give us advice on ice fishing 22．What does the underlined word “spook”in the third paragraph probably mean?
A．Catch. B．Watch. C．Frighten. D．Attract. 23．Why do many good anglers fish from a shelter early in the ice fishing
season?
A．It can hide their movements from the fish.
B．They can be safe inside the shelter.
C．It can protect them from cold weather.
D．They can move around it freely.
B
Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach(菠菜)to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some chi ldren who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
24. A good title for this reading passage is______.
A. Popeye the Sailor
B. A Mistake with Numbers
C. The Truth About Spinach
D. Folic Acid Makes You Strong
25. Why did many people eat spinach after they saw Popeye the Sailor?
A. They thought spinach made them strong.
B. They thought Popeye was funny.
C. Spinach had a lot of iron.
D. People liked folic acid.
26. A research group told people that spinach______.
A. had more iron than other green vegetables
B. was a green vegetable
C. had less iron than other green vegetables
D. made Popeye strong
27. The reading passage says that perhaps Popeye got his strength from______.
A. iron
B. folic acid
C. spinach
D. exercise
C
Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour.
The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebrafish skin colour is determined by pigment cells, which contain melanosomes (黑色素). The number, size and darkness of melanosomes per pigment cell determines skin colour.
It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation(变异) in the gene for melanosome production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colour, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson.
28. The passage mainly tells us that ________.
A. people can not change their skin colour without any pain
B. scientists have found out that people’s skin colour is determined by the gene
C. pop king Michael Jackson often changed his skin colour as he liked
D. the new discovery could lead to search into ways to change skin colour safely
29. Scientists have done an experiment on a dark-striped zebrafish in order to ________.
A. find the different genes of humans’
B. prove the humans’ skin colour is determined by the pigment gene
C. find out the reason why the Africans’ skin colour is dark
D. find out the ways of changing people’s skin colour
30. The reason why Europeans are light-skinned is probably that ________.
A. they are born light-skinned people
B. light-skinned Europeans have mutation in the gene for melanosome
production
C. they have fewer activities outside
D. they pay much attention to protecting their skin
31. The writer’s attitude towards the discovery is ________.
A. neutral
B. positive
C. negative
D. indifferent
D
Jerry was a unique manager because he had several waiters who had followed him around from restaurant to restaurant. The reason the waiters followed Jerry was because of his attitude. He was a natural motivator. If an employee was having a bad day, Jerry was there telling the employee how to look on the positive side of the situation.
Seeing this style really made me curious, so one day I went up to Jerry and asked him, “I don’t get it! You can’t be a positive person all of the time. How do you do it?”Jerry replied, “Each morning I wake up an d say to myself, ‘Jerry, you have two choices today. You can choose to be in a good mood or you can choose to be in a bad mood.’ I choose to be in a good mood. Each time something bad happens, I can choose to be a victim or I can choose to learn from it. I choose to learn from it. Every time someone comes to me complaining, I can choose to accept their complaining or I can point out the positive side of life. I choose the positive side of life. The bottom line: It’s your choice how you live life.” I reflect ed on what Jerry said. Later, I left the restaurant industry to start my own business. We lost touch, but I often thought about him when I made a choice about life.
Several years later, I heard that Jerry did something you are never supposed to do in a restaurant business: he left the back door open one morning
and was held up at gun point by three armed robbers. While trying to open the safe, he forgot the password, nervous. The robbers panicked and shot him. Luckily, Jerry was found relatively quickly and rushed to the local hospital. After 18 hours of surgery and weeks of intensive care, Jerry was released from the hospital with fragments（碎片） of the bullets still in his body.
I saw Jerry about six months after the accident. When I asked him how he was, he replied, “The first thing that went through my mind was that I should have locked the back door,” Jerry replied. “Then, as I lay on the floor, I remembered that I had two choices: I could choose to live, or I could choose to die. I chose to live.” “Weren’t you scared? Did you lose consciousness?” I asked. Jerry continued, “The doctors and nurses were great. They kept telling me I was going to be fine. But when they wheeled me into the emergency room and I saw the expressions on the faces of the doctors and nurses, I got really scared. I knew I needed to take action.”
“What did you do?” I asked. “Well, there was a big, strong nurse shouting questions at me,” said Jerry.“She asked if I was allergic (过敏的)to anything. “Yes,” I replied. The doctors and nurses s topped working as they waited for my reply. I took a deep breath and yelled, “Bullets!”Over their laughter, I told them. “I am choosing to live. Operate on me as if I am alive, not dead.”
Jerry lived thanks to the skill of his doctors, but also because of his amazing attitude. I learned from him that every day we have the choice to live fully.
32. The author left Jerry’s restaurant because he___________.
A. wanted to start business on his own
B. was afraid of another robbery later
C. was not equal to the job any longer
D. didn’t get along well with others
33. What was Jerry really afraid in the emergency room?
A. The doctors and nurses gave him up.
B. He decided to take action to live again.
C. He saw the expressions of the doctors and nurses.
D. He might not be saved by doctors and nurses.
34. From the passage we can learn that Jerry was _________.
A. no longer positive to his life after the operation
B. optimistic even when things were at their worst
C. Jerry influenced all his colleges in many ways
D. badly injured and stayed in hospital for six months
35. Which of the following is conveyed in this article?
A. Where there is life, there is hope.
B. Everything comes to him who waits.
C. Humor is the best medicine that creates miracle.
D. Attitude determines everything.

I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags huddling together on the top step. “Any old papers, lady？” asked one of them. I was busy. I wanted to say “no” until I looked down at their feet. They were wearing th in little sandals(凉鞋), wet with heavy snow. “Come in and I'll make you a cup of hot cocoa.” They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread to fight against the cold outside. Then I went back to the kitchen and started cooking. The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, “Lady, are you rich？” “Am I rich? Pity, no！” I looked at my worn-out slipcovers(椅套). The girl put her cup back in its saucer(茶碟)carefully and said, “Your cups match your saucers.” They left after that, holding their papers against the wind. They had reminded me that I had so much for which to be grateful. Plain blue china cups and saucers were only worth five pence. But they matched. I tasted the potatoes and stirred(搅动)the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a regular job, these matched, too. I moved the chairs back from the fire and cleaned the living room. The muddy marks of little sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am. 36．Which of the following would be the best title for the text? A．Lady, are you rich? B．A story of Thanksgiving Day C．Don't forget how rich you are D．Does cups and saucers match well? 37．Which of the following statements is NOT true according to the passage? A．The girl thought the writer was rich just because she wanted to make the writer happy. B．The writer had thought she wasn't rich because her supplies were not expensive.
