题目内容

You may know the English letters A, B and C. But do you know there are people called ABC? You may like eating bananas. But did you know there is such thing as a “banana person”? How strange! Are these people from “another earth”? No. They are just Chinese people like you and me.

ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a “banana person”. A banana is yellow outside and white inside. So, when a person is a banana, he or she is white inside-thinking like a Westerner and yellow outside-looking like a Chinese.

Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them don’t speak Chinese. Also, they are not interested in Chinese politics.

But if ABCs cannot speak Chinese, can we still call them Chinese people? Yes, of course. They are Chinese. They are overseas (海外的) Chinese. These people may be citizens(公民) of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are not people of the People’s Republic of China. For example, we all know the famous scientist C. N. Yang (杨振宁). He got the Nobel Prize for Physics in 1957. Chinese people love him. But he is an American citizen.

A. three English letters

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

When I was little, I’d see tons of bats flying around streetlights at night in my neighborhood in upstate New York. But I’ll never forget the first time when I saw a bat up close. By the time I turned 7, though, I noticed something strange: All the bats in my neighborhood had disappeared, and I wondered why.

Then, three years ago, when I was 11 and visiting the state fair, I learned what had happened to my town’s bats. A disease called “white nose syndrome” had killed 93 percent of New York State’s bats. I was horrified. Then I wrote a letter to the host of an environmental program on the local radio station, asking if they could do a show on bats. They did!

But I still wanted to find a way to educate people face to face. I reached out to a teacher I had in elementary school and asked if I could make a presentation to her class. I described how bats help farmers by eating crop-damaging insects. It went over so well that other teachers started requesting me. Over the past three years, I’ve talked in front of everyone from 5-year-olds to senior citizens! Many people think that bats are blind, and that they always carry diseases, but none of that is true. The more I present, the more I notice that I am changing minds.

And while getting people to respect bats is pretty hard, getting them to respect me has been difficult too. When I first applied to host a booth (摊位) at a local street fair, the managers thought I was too young. But I refused to take “no” for an answer. I continued to make my case, and they finally said yes! The best part is, I impressed them so much— 100 visitors on my first day — that they now invite me back every year.

1.All the bats in the neighborhood disappeared because they .

A. were killed by a disease

B. moved to another habitat

C. were hunted by other animals

D. hid in a place where people couldn’t find them

2.The author wrote a letter to the host in order to ask them to .

A. donate some money to save bats

B. make a radio program about bats

C. announce new findings about bats

D. finish some questionnaires about the fair

3.How did the author save bats?

A. By building a new home for them.

B. By volunteering to work in the wild.

C. By improving their living environment.

D. By educating people that they are beneficial.

4.What does the underlined phrase “make my case.” in the last paragraph mean?

A. make an impressive persuasion.

B. look into the matter.

C. quarrel with them

D. stick to the facts.

Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably, mosquitoes can do more than cause an itchy(发痒的)wound. Some mosquitoes spread several serious diseases,including Dengue,yellow fever and malaria.

Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.

Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.

But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains,use three senses to find a blood meal.

Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.

Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr. Dickinson said, at first, the mosquitoes showed no interest in the objects at all. “What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2, they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点).”

This suggested to the researchers that a mosquito’s sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal,they also follow visual signals.

1.What do mosquitoes mainly use to find their targets?

A. Sense of smell B. Sense of touch

C. Sense of sight D. Smart brains

2.The first response of the mosquitoes to the objects in the experiment is _______.

A. to fly to the dark ones

B. to catch and stick to them

C. to take no notice of them

D. to attach themselves to them

3.How can we avoid being attacked by mosquitoes according to the text?

A. Don’t let them see us.

B. Use dark objects to stop them.

C. Make them fly back and forth for hours.

D. Attract them to objects full of carbon dioxide gas.

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

A. How Do Mosquitoes Survive?

B. Why Do Mosquitoes Need Blood?

C. How Do Mosquitoes Choose to Bite You?

D. Why Do Mosquitoes Attack the Human Being?

I just realized that while children are dogs-loyal and affectionate-teenagers are cats.

1. You feed it, train it, and boss it around. It puts its head on your knee and gazes at you as if you were a Rembrandt painting. It bounds indoors with enthusiasm when you call it. However, around age 13, your adoring little puppy(child) turns into a big old cat(teenager). Then when you tell it to come inside, it looks amazed, as if wondering who died. Instead of following your doorsteps, it disappears. 2.

Not realizing that the dog is now a cat, you think something must be desperately wrong within. Since you're the one who raised it, you assume that you did something wrong. Now you're dealing with a cat. Filled with guilt and fear, you redouble your efforts to make your pet behave. 3. Call it, and it runs way. Tell it to sit, and it jumps on the counter.

Instead of continuing to act like a dog owner, you can learn to behave like a cat owner. Put a dish of food near the door, and let it come to you. 4. You sit still,and it will come, seeking that warm, comforting lap it has not entirely forgotten. Be there to open the door for it. One day your grown-up child will walk into the kitchen,give you a big kiss and say, "You've been working hard all day. Let me get those dishes for you."_ 5.

A. It's so easy to be a dog owner.

B. Children as cats can turn to their parents.

C. You won't see it again until it gets hungry.

D. Then you'll realize your cat is a dog again.

E. Teenagers can understand and appreciate their parents' love.

F. But remember that a cat needs your help and your affection, too.

G. However, all the efforts made before now produce the opposite of the desired result.
