When people reunite with their loved ones, it’s usually all extremely happy moment. But what is their most common response to seeing them again? It may seem strange，but most of the time they break down in tears.
Now a group of psychologists from Yale University say they have found the reason why, and that crying tears of joy may well be the body’s way of keeping emotional balance. “They seem to take place when people are overtaken by strong positive emotions, and people who do this seem to recover better from those strong emotions,” Oriana Aragon, the lead researcher said.
Aragon and her fellow psychologists looked at hundreds of participants’ emotional responses to different things, including happy reunions and cute babies. Many participants said they would react in a negative or aggressive way to the positive things —— to cry at happy moments and want to pinch(捏)a cute baby’s face or even tell them “I want to eat you up!” But then researchers found that these people were able to calm down from strong emotions more quickly.
There are many other examples of times when people respond to a positive experience with a negative emotional reaction. At an exciting concert, fans scream at their idols(偶像). People who have just had a big lottery win are often in floods of tears. “These findings advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together.” said Aragon．

Dolphins are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time --- at least twenty or thirty years.
Like some animals, dolphins use sound to help them find their way around. They also use these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.
Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.
There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903 Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area－except for The Penguin.
Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.
1.Dolphins are different from many other animals in that they _____.
A. live in groups B. have their own language
C. are warm-blooded D. have large brains
2.Which of the following does the dolphin use to help it find its way around?
A. Its jaw. B. Its ears
C. Its nose. D. Its eyes.
3.By telling the story of Jack the writer wanted to show that _____.
A. people are cruel to animals
B. Jack is different from other dolphins
C. dolphins are friendly and clever
D. dolphins should be protected by law
4.Why did the sailors off the coast of New Zealand look for Jack?
A. They wanted his help.
B. They enjoyed playing with him.
C. He was lonely and liked to be with people

To master a language one must be able to speak and understand the spoken language as well as to read and write．Lenin and his wife Krupskaya translated a long English book into Russian．But when they went to England in 1980, English people couldn’t understand what was said to them．These days more foreigners are coming to China and more and more Chinese are going out to foreign countries to work or study．So the spoken language is becoming more and more important．
Speaking, of course, can’t go without listening．If you want to pronounce a word correctly, first you must hear it correctly．The sounds of the Chinese and English language are not exactly the same．If you don’t listen carefully, you’ll find it difficult or even impossible to understand the native speakers．
Well, what about writing? Like speaking, it’s to exchange ideas．People generally use shorter words and shorter sentences in their writing．The important thing is to make your idea in your head and then to write it in clear lively language．
Chinese students read far too slowly．If you read fast, you understand better．If you read too slowly, by the time you have reached the end of a page you have forgotten what the beginning is about．When you meet with new words, don’t look them up in the dictionary．Guess the meaning from the context(上下文)．You may not guess quite correctly the first time, but as new words come up again and again in different contexts, their meaning will become clearer and clearer．If you look up every word, you’ll never finish a book．
Students of a foreign language need a particular knowledge, the knowledge of the life, history and geography of the people whose language they’re studying．They should study these subjects in the foreign language, not only in translation．In this way one can kill two birds with one stone: learn a foreign language and get some knowledge of the foreign country at the same time．
1.In the first paragraph the writer tells us ．
A．how to speak English
B．how to read and write
C．why spoken English is important
D．why English people couldn’t understand Lenin
2.In his last point the writer advises us ．
A．to kill two birds with one stone
B．to learn two languages at a time
C．to study all the subjects in a foreign language
D．to get some knowledge of the foreign country whose language you are studying．
3.In the fourth paragraph the writer give some advice on ．
A．how to read faster
B．how to guess the meaning from the context
C．how to look up new words in the dictionary
D．how to grasp the general meaning of a passage
4.“To kill two birds with one stone” means ．
A．to get some particular knowledge
B．to get more than what one pays
C．the stone is too big
D．the birds are blind enough

WHEN you buy cooking oil in the supermarket, you may notice that some brands are labeled as “GM (genetically modified)-free”. So, what is genetic modification? Are GM foods safe?
These questions have been put back into the spotlight recently. On Nov 19, the Food and Drug Administration (FDA) in the US announced that it had approved the AquAdvantage salmon (三文鱼) to go on the market, making it the first genetically modified animal to be approved as food anywhere in the world.
GM foods are plants or animals that have been given a gene from another plant or animal to make them stronger in some way. The AquAdvantage salmon contains a gene from another type of salmon that makes it grow faster.
Although the FDA has said “food from the fish is safe to eat”, some believe that scientists can’t completely understand the potential health risks of GM foods, simply because they’re so new. Others worry that the fish could escape into the wild and cause ecological (生态的) problems.
GM crops have experienced the same controversy, even though GM technology cuts down on the use of pesticides (杀虫剂) on crops and increases yields.
While GM animals are new, GM crops have already appeared on our plates. A total of 28 countries in the world including the US, Brazil and India planted 181.5 million hectares (1.815 million km2) of GM crops in 2014, according to the International Service for the Acquisition of Agri-biotech Applications. In China, we grow GM cotton and papaya (木瓜) and import GM soybeans, corn, rape (油菜), cotton and beets (甜菜) from abroad.
Due to safety worries, many countries have regulations for producing and selling GM food.
In European Union countries, each GM food must be approved before it can be used. This process can take up to 17 months. The origin of all GM foods must also be traceable (可追溯的) , and all food with a GM content of more than 0.9 percent must also be labeled, according to EU website europa.eu.
The US is less strict about GM foods. According to FDA regulations, companies introducing new GM foods to the market should report them at least 120 days before release. The labeling is voluntary (自愿的), except that a product cannot be labeled as “GM-free” if genetically modified materials are used.
In China, GM foods can only be produced after strict tests by the Ministry of Agriculture say that they are safe. All food that is made from GM crops or contains GM ingredients must be clearly labeled on the wrapper (包装).
1.According to the text, the AquAdvantage salmon ______.
A. tastes better than normal salmon
B. is a product that mixes several types of fish
C. has a gene from a different type of salmon
D. remains to be approved in several countries
2.One of the reasons for many people to worry about the AquAdvantage salmon is that ______.
A. the gene that makes them grow faster can work on humans too
B. there are possible health risks that even scientists might not have figured out yet
C. they could possibly become threats to other wild species
D. they are not nutritious enough or might taste strange
3.From the text, it can be concluded that GM crops _____.
A. no longer cause any controversy
B. have already been planted in some countries
C. are popular because they don’t need pesticides
D. can increase yields, making them welcome in countries like Japan
4.Which of the following is TRUE about regulations for producing and selling GM food?
A. All food with GM content must be labeled in European countries.
B. In the US, the AquAdvantage salmon will have to be labeled as GM food.
C. In France, every GM food that is about to go on the market must be reported at least 120 days before release.
D. In China, all food that is made from GM crops or contains GM ingredients must be clearly labeled on the package.
