How To Study English In China

English is obviously not the native language in China. Although many Chinese want to improve their English level to the amount needed in daily work, it’s very hard when only a few people speak English around them. 1. Here are a few tips that might help.

Join a school with native teachers to guide you.

2.The more exposure you can get to these foreign teachers, the faster and better you’re going to learn English. If a school doesn’t give students maximum exposure to native English speakers’ classes, find one that does.

Read English daily.

This means using websites that are permitted in China, accessing English texts, newspapers and books. Read short stories in English. When you come across words you don’t know write them down immediately. 3.

Find some English speakers.

Spend time with them and share conversations. There is nothing better for learning any language than finding native speakers of the language to practice with. When you speak, you are practicing every aspect of the language(except writing) in the most efficient way possible.

Memorize vocabulary.

Write new words in a notebook every week, with English definitions and a sample sentence, not a Chinese translation. 4. Carry it with you everywhere you go. Even if you have a question about something that you see and you don’t know the English word, write it down in your own language with the plan to look it up later and learn that word in English.

5.English is not well controlled by grammar rules. For every rule, there is an exception to that rule. Your time will be better spent in watching movies and learning from them than studying grammar for long hours. Find someone to write emails in English to or write a dairy every day.

There are many other ways to improve your English. Come on!

A. Learn to write.

B. Watch an English film once a month.

C. What can you do to study more English?

D. There are many English speakers in China.

E. You can do this by writing in your notebook.

F. Follow a soap opera, comedy or radio program or TV drama.

G. You should be carrying a notebook with you everywhere you go just to write down something important.

Every year more people recognize that it is wrong to kill wildlife for “sport.” Progress in this direction is slow because shooting is not a sport for watching, and only those few who take part realize the cruelty and destruction.

The number of gunners, however, grows rapidly. Children too young to develop proper judgments through independent thought are led a long way away by their gunning parents. They are subjected to advertisements of gun producers who describe shooting as good for their health and guncarrying as a way of putting redder blood in the veins (血管). They are persuaded by gunner magazines with stories honoring the chase and the kill. In school they view motion pictures which are supposedly meant to teach them how to deal with arms safely but which are actually designed to stimulate (刺激) a desire to own a gun. Wildlife is disappearing because of shooting and because of the loss of wildland habitat (栖息地). Habitat loss will continue with our increasing population, but can we slow the loss of wildlife caused by shooting? There doesn’t seem to be any chance if the serious condition of our birds is not improved.

Wildlife belongs to everyone and not to the gunners alone. Although most people do not shoot, they seem to forgive shooting for sport because they know little or nothing about it. The only answer, then, is to bring the truth about sport shooting to the great majority of people.

Now, it is time to realize that animals have the same right to life as we do and that there is nothing fair or right about a person with a gun shooting the harmless and beautiful creatures. The gunners like to describe what they do as character-building, but we know that to wound an animal and watch it go through the agony of dying can make nobody happy. If, as they would have you believe, gun-carrying and killing improve human-character, then perhaps we should encourage war.

1.According to the text, most people do not seem to be against hunting because ________.

A. they have little knowledge of it

B. it helps to build human character

C. it is too costly to stop killing wildlife

D. they want to keep wildlife under control

2.The underlined word “agony” in the last paragraph probably means ________.

A. formB. conditionC. painD. sadness

3.According to the text, the films children watch at school actually ________.

A. teach them how to deal with guns safely

B. praise hunting as character-building

C. describe hunting as an exercise

D. encourage them to have guns of their own

4.It can be inferred from the text that the author seems to ________.

A. blame the majority of people

B. worry about the existence of wildlife

C. be in favour of war

D. be in support of character-building

If you are a traditional traveller who believes cameras are irreplaceable,here are some things you should pay attention to when looking for the perfect camera.

Sensor size

Along with the megapixel (百万像素) count,the size of the sensor dictates the general image quality as well as the camera's performance in low light. It also determines whether the camera can electronically put the details it captures bigger enough to see—which is what makes the pictures not clear enough to see when you view the photos on a bigger screen.

Portability

“The important thing is that the camera isn't too big or heavy,and that you have a good zoom (变焦距镜头) range for both wide-angle and telephoto shots (远距摄影照片),”Atherton told CNN.A good choice would be a slim,light pocket camera with a high-qualified built-in optical zoom. “These are very popular for travel as they are light,but built with a telephoto lens that can zoom up to 60 times,” Atherton said.

Zoom and shutter (快门) speed

For action or crowd shots,a fast shutter speed is a key factor. “When dealing with anything that's active—wildlife or people in action on the street—faces change within a tiny part of a second,” said Arnold,“a fast shutter speed is helpful in shooting the several hundred photos you might need to get that single winning shot.”

1. According to Atherton,what isn't a requirement for an ideal camera?

A.Portable shape.

B.Wide-ranged zoom.

C.Good telephoto lens.

D.Reasonable sensor size.

2.What will contribute to a satisfactory photo of a running lion in the wild?

A.The sensor size. B.The zoom range.

C.The shutter speed. D.The megapixel.

3.Which of the following can be the best title of the passage?

A.How to choose ideal travel cameras?

B.How to put a camera into good use?

C.A fashionable camera—up for sale

D.A high-quality camera—a modern life's must

Every living thing has genes. Genes carry information. 1. They make sure that humans give birth to humans and cows give birth to cows. They also make sure that a dog doesn’t give birth to a frog, or an elephant to a horse. However, genetic engineers take genes from one species-for example, a snake, and transfer them to another-for example, corn. 2. Such new life forms have been described, by some scientists as a real-life Frankenstein(科幻怪人).

Genetic engineers put duck genes into chicken to make the chickens bigger. They put hormones(激素) into cows to make them produce more milk. They put genes from flowers into beans and from fish into tomatoes. 3. It just makes them easier and faster for the farmer to grow.

The effects of genetic engineering on the natural world may be disastrous. The engineers may create strange life beings, or monsters. that we cannot control. 4. They’ll have to find one, fight for one-or kill for one. It may be your land they fight for-or you that they kill. Moreover, the effects of these experiments can often be cruel. In America, pigs were given human genes to make them bigger and less fatty. The experiment failed. The pigs became very ill and began to lose their eyesight. We would all like a better, healthier and longer life, and genetic engineering might give us this. On the other hand, it may be a dangerous experiment with nature. In the story of Frankenstein, the doctor created such a terrible and dangerous monster that he had to destroy it. 5.

A. The information tells us what to do or what not to do

B. We must make sure that this tale remains a story-and no more than that

C. This doesn’t make them cheaper, tastier, or healthier

D. The new life forms have no natural habitat or home

E. Then they feed the tomatoes to the fish

F. In this way a new life form is created

G. They are passed on from generation to generation

My teacher, Mr.August J.Bachmann, was the most influential teacher I ever had.

I had gotten into trouble in his class:Another student had pushed me for fun,and I became angry and began to hit him.Mr.Bachmann stopped the fight,but instead of sending me to the office,he sat me down and asked a simple question:"Penna,why are you wasting your life?Why aren't you going to college?"

I didn't know anything about colleges or scholarships.No one had ever considered that a fatherless boy from the poorest neighborhood had a future.That day,instead of rushing off for lunch,he stayed and explained possible education options to me.At the end of our talk,he sent me to see a secretary who had a child at a state college.This was in 1962 at Emerson High School in Union City,New Jersey.

Well,53 years have passed, and what have I done with the knowledge he gave me?I gained a PhD from Fordham University when I was only 29.I taught English and social studies and then moved up the chain of command from teacher to principal.

I've sat on the board for Magnet Schools of America and represented that organization at the United Nations.I've won a number of great educational awards.But where would I be if a truly caring teacher had not taken the time out of his lunch period to speak to me? It was without question only his confidence in me that helped me forward.

I have repaid his kindness hundreds of times by encouraging misguided youngsters to aim higher. If I have saved any children, it is because of him. If I have been a successful educator, it is because I had a great role model in Mr. Bachmann.

1.The writer ________ before Mr.Bachmann talked to him.

A. was an active boy

B. liked making troubles in class

C. was an aimless boy

D. would get punished by his teachers

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

1.The difficulty the team of engineers met with while making the robotic fly was that ________.

A. they had no model in their mind

B. they did not have sufficient time

C. they had no ready-made components

D. they could not assemble the components

2.It can be inferred from paragraphs 3 and 4 that the robotic fly ________.

A. consists of a flight device and a control system

B. can just fly in limited areas at the present time

C. can collect information from many sources

D. has been put into wide application

3.Which of the following can be learned from the passage?

A. The robotic flyer is designed to learn about insects.

B. Animals are not allowed in biological experiments.

C. There used to be few ways to study how insects fly.

D. Wood’s design can replace animals in some experiments.

4.Which of the following might be the best title of the passage?

A. Father of Robotic Fly

B. Inspiration from Engineering Science

C. Robotic Fly Imitates Real Life Insect

D. Harvard Breaks Through in Insect Study
