Have you wondered why different animals or pests have their particular colours? Colours in them seem to be used mainly to protect themselves.
Birds, especially seagulls are very fond of locusts (蝗虫), but birds can’t easily catch locusts because locusts change their colours together with the change of the colour of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown colour as crops have. Some other pests with different colours from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of colouring is to protect them. Bears, wolves and other beasts move quietly through forests. They are usually invisible(can’t be seen) to the eyes of hunters, because they have the colour much like the bark（树皮）of trees.
An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all.
1. This passage mainly talks about _______.
A. the change of colour in locusts
B. animals or pests can dye（染色）themselves different colours
C. how a certain sea fish protects itself
D. the protective colour of animals and pests

Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.
Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
1.From the passage we learn that locusts________.
A. are small animals B. are easily found by birds
C. are dangerous to their enemies D. change their colors to protect themselves
2. How can pests with different colors from plants keep out of danger?

Do you ever wonder why the English have one word for some animals and a different one for their meat? Why do they use pig and pork, cow and beef, and sheep and mutton? To find it out, we have to go back to 1066, when the Norman French invaded England and put a French king on the English throne (王位), which not only changed the government but also changed the language. French became the language of the upper classes of society. And it remained that way for 300 years. Only these high society people could afford to eat meat. As a result, French words like porc (pork) and beouf (beef) came into the English language. However, poor English farmers raised the animals. So the English language retained the words pig and cow from the Native Anglo-Saxon.
The Norman French added about 10,000 French words to the English language. Seventy-five percent of them are still in use today.
In French grammar, nouns have either a male or female gender (性别), so adjectives (形容词) take different forms for each. English has only one adjective that does this, and it came from French. The word “blond” describes someone with light-colored hair. “Blond” is used for men, and “blonde” describes women. And they are also nouns.
Some French words that entered the English language have taken on completely different meanings. The French phrase “a la mode” means “in style”. In English, the phrase means “with the ice cream”. Someone must have decided something eaten with ice cream was in style!
Now, as you learn English, you’re on your way to learning French!
1.French was once popular among the upper classes of the UK because_____.
A. too many French moved to Britain
B. French brought animals with them
C. the king and his officials spoke French
D. the king allowed French to be spoken
2.Which word can replace the word “retained” in Paragraph 1?
A. Chose B. Kept C. Introduced D. Give up
3.Why does an English speaker find French easy to learn?
A. Because English and French share similar pronunciations.
B. Because English grammar and French grammar are similar.
C. Because a large number of English words have French origins.
D. Because English has great influences on the French language.
4.French grammar is very different from English grammar because ______.
A. no words have the same pronunciation
B. all words have the same pronunciation
C. English nouns have a male or female gender
D. French nouns have different adjective forms
5.What conclusion can we draw from the text?
A. Language is closely related to history and culture.

According to language experts, English speakers who have never studied French may already know 15,000 French words! Between one-third and two-thirds of all English words have French origins. Some words such as “possible” and “avenue” are the same in French and English; only the pronunciations change. Other words such as “ballet” keep their French pronunciations in both languages.

Have you ever wondered why people drive on a different side of the road? It might seem bizarre that U. K. drivers stay on the left, but they’re not the only ones. Around 35 percent of the world population do the same, including people in Ireland, Japan, and some Caribbean islands.
Originally, almost everybody traveled on the left side of the road. However their way of transport was quite different from today: Think about four legs instead of four wheels. For Medieval swordsmen on horseback, it made sense to keep to the left to have their right arms closer to their enemies. Getting on or off was also easier from the left side of the horse, and safer done by the side of the road than in the center.
So why did people stop traveling on the left? Things changed in the late 1700s when large wagons (货车) pulled by several pairs of horses were used to transport farm products in France and the United States. The wagon driver sat behind the left horse, with his right arm free to use his whip to keep the horses moving. Since he was sitting on the left position, he wanted other wagons to pass on his left, so he kept to the right side of the road.
The British Government refused to give up their left-hand driving ways, and in 1773 introduced the General Highways Act, which encouraged driving on the left. This was later made law thanks to The Highway Act of 1835.
When Henry Ford showed his Model T in 1908, the driver’s seat was on the left, meaning that cars would have to drive on the right hand side of the road to allow front and back passengers to exit the car onto the roadside. However, British drivers remain on the left, and this is highly unlikely to change.
1.What does the underlined word “bizarre” in Paragraph 1 mean?
A. Funny. B. Strange.
C. Wrong. D. Difficult
2.Why did people riding the horse travel on the left in history?
A. It was safer to keep on the left
B. It was easier to carry goods.
C. It was easier for them to fight
D. It was necessary to control the horse.
3.What made drivers of large wagons travel on the right?
A. Their sitting position.
B. The road conditions.
C. The number of horses.
D. The products in the wagons.
4.Which of the following may be the best title for the text?
A. UK Drivers Still Go On The Left
B. Why People Like Sitting On The Left Side
C. The History Of Transportation Means
D. The Reasons For Different Driving Sides

If you have ever been left wondering why your emails are riddled(充斥着) with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands.
Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and it can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction(互动) between our thoughts and the tools we use to express them."
Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze(分析) elements of the essays, such as range of vocabulary, sentence complexity and the cohesion(衔接) of the writing.
Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal (内在的) word search, resulting in a larger variety of words.
In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting.
This is the first study to show that changing people’s typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea.
1. The underlined “it” in the second paragraph refers to______.
A. the writing style
B. typing too fast or fluently
C. the vocabulary
D. which hand to use for typing
2. Which of the following statements is true according to the passage?
A. The study was carried out in 103 universities.
B. The researchers drew the conclusion by interviewing students about their feelings in the writing process.
C. The typing speed should be as slow as possible.
D. There is no previous study related to the topic before.
3. What is the author’s attitude to the research according to the passage?
A. objective B. doubtful
C. critical D. supportive
4.Which is the best title of the passage?
A. How to become a good writer?
B. Typing with both hands could make you a worse writer.
C. Slower typing, fewer mistakes.
D. Elements weakening the writing process

How Do Animals Catch their ZZZ's（打鼾声）？
Different creatures have developed some pretty creative ways to get their rest and stay safe． The lizard likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest． If a snake tries to slither up the branch to eat it, it will shake the branch and knock the lizard off, and the lizard will fall safely into the water． Chameleons can change color to match their surroundings in order to hide even while sleeping．
Gorillas like to sleep high in the trees． They build a new bed every night, sometimes taking up to half an hour to pile branches, twigs, and leaves into a comfortable bed． Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks, they don't use a nest． They just lock their feet around a branch and hang on． A special tendon in their legs is automatically tight when they are at rest, so they won't let go and fall．
Dolphins live underwater, but must come to the surface to breathe． Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing． Seals also do this, lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface． Some ducks may also have this ability, and actually sleep with one eye closed and one eye open．
1.How does a chameleon protect itself while sleeping?
A．By changing its body colors
B．By hanging out over a pond．
C．By sleeping with half their brain．
D．By making beds with branches．
2.Why will not birds fall when they are at rest?
A．They build nests and sleep in them．
B．They fall asleep automatically．
C．They have a loose tendon in their legs．
D．They lock their feet around a branch．
3.How do dolphins breathe?
A．They breathe underwater．
B．They come to the surface to breathe．
C．They breathe underwater or come to the surface to breathe．
D．We don't know．
4.What does the writer intend to tell us?
A．The cleverest animal is the gorilla because it can make beds．
B．Differences in habitat can lead to different living habits．
C．The ways animals catch their ZZZ's are pretty much the same．
D．In order to protect themselves most animals choose not to sleep

Have you ever wondered what wild animals do when no one is watching? Scientists have been able to record the “private” moments of wildlife with leading-edge technology. Low-cost, dependable and small modern cameras are of big help.
Cameras placed in hard-to-reach places have taken videos of everything from small desert cats to later snow loving felines (猫科) in the northern Rocky Mountains. These cameras are important tools to learn new information on wildlife.
Some videos help scientists see the effects of climate change. For example, the desert animal javelin and the tree-loving coatimundi have been caught on cameras north of their normal home. This could mean global warming is enlarging their living area northward.
Researchers use cameras along with global positioning systems, or GPS. They attach GPS devices (设备) to mule deer and antelope in and around Yellowstone National Park. Then they can record their movements, or migrations (迁移) . These cameras can be left in very rural (荒野的) areas for days, weeks or even month. They can provide information on how many animals are moving over a given period of time.
Rural video can show details about animal behavior, such as the calls made by migrating. Also some cameras record animal life and show everything from bison in Saskatchewan, Canada, to the underwater weed forest off California’s Channel Islands.
However, rural cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way. Even with such problems, rural cameras are clearly an important scientific tool in researching wild animals.
1.Which of the following helps scientists know about climate change?
A. How active animals are. B. What animals eat.
C. Where animals go. D. When animals move.
2.Where are the cameras fixed?
A. Under water B. In the field
C. On GPS devices. D. On wild animals.
3.What may be the disadvantage of the rural cameras?
A. They affect animals' search for good.
B. They make wild animals puzzled.
C. They make animals attack one another frequently.
D. They might bring danger to animals.
4.Which of the following can be the best title for the text?
A. Cameras Record Animals in the Wild B. Every Coin Has Two Sides
C. Animals No Longer Have Secrets D. An Invention Makes Animals Mad
