Scientists have observed that humans experience happiness from a wide range of stimuli(刺激), from traveling to an ideal destination to redecorating one’s home or from winning a game of soccer to eating a delicious meal. Simply watching a favorite television show or laughing at a funny joke can lift a depressed mood. While the happiness produced by such experiences tends to be short lived, a wide social network does promote a more long-lasting state of happiness as a lifestyle.

Surprisingly, income is not a primary factor in determining a person’s level of happiness once the basic needs of food, clothing, and shelter have been met. More important is one’s social network. Being socially active may be more effective in increasing one’s immunity(免疫力)to illness than a vaccine. Misery may love company, but so does happiness, and having close friends and family is vital to one’s overall level of happiness. Even sharing one’s home with an animal companion can make a person happier.

阅读下面短文，根据其内容写一篇 60 词左右的内容概要。

Scientists have announced that they have cloned the first human embryo. This has caused much debate round the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable human tissues—such as bone or lung tissue—that could be used to save human lives. On the other hand, many people, including some scientists, disagree and are afraid that, if mankind toys with nature in this way, we may be on our way to producing a real-life Frankenstein’s monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were worried that cloning would lead to more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific advance.

Ian Wilmut, the Scottish scientist who created Dolly, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, his intention has never been to create copies of humans. Instead, he thinks research efforts should concentrate on creating new tissues and organs that can be used to cure diseases like cancer. However, some people believe that cloning human embryos with the intention of destroying them shows no respect for human life.

Even though human cloning is causing a lot of anxiety, it is good news for Faye Wilson, a 41-year-old saleswoman who cannot have a baby. “I am anxious to have a child of my own,” she says. “I don’t want to adopt someone else’s child—if I had the chance, I would have a cloned baby right now.”

While cloning human embryos is not legal in many countries, some scientists are already pushing ahead with research in order to produce a cloned human baby. Severino Antinori, an Italian physician, has declared that he wants to be the first to clone a human being.

“Global warming could make humans shorter,” warn scientists who claim to have found evidence that it caused the world's first horses to shrink(收缩) nearly 50 million years ago. In fact, a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammals – horses, in this case.

The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago. As temperature went up，their size went down, and vice versa（反之亦然）;“ At one point they were as small as a house cat,” said Dr Jonathan Bloch, curator（博物馆长） of the Florida Museum of Natural History, which was quoted by the "Daily Mail" as saying.

The scientists say that the current warming could have the same effect on mammals and could even make humans smaller."Horses started out small, about the size of a small dog . What's surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that exactly corresponds to the global warming event, followed by cooling”

"It had been known that mammals were small during that time and that it was warm, but we hadn't realized that temperature specifically was driving the evolution of body size," Dr Bloch said in the "Science" journal.

1.How did scientists find out the horses’ earliest appearance millions of years ago?

A. searching the data on the net

B. sorting through the pictures of ancient times

C. using fossils to follow the evolution

D. analyzing the related images

2.What can we infer form the passage?

A. As temperatures went up, horses dramatically increased in size

B. The temperature has no effect on mammals’ evolution

C. As temperatures went up, horses’ size went down

D. In history, it used to be warm at early times , followed by a certain period of sharply cooling down.

3.Which is the most closest meaning to the underlined words most probably mean _______.

A. react to　　　　　　　　　　 B.　 be contradictory to　

C. be consistent with　　　　　　 D.　 differ from

4.What is the best title of the passage?

A. Global warming is to disappear

B. The temperature on earth is to decrease

C. Global warming makes human shorter

D. Mammals are dying out.

Scientists in Argentina have created the world’s first cow with two human genes that will enable it to produce human-like milk.

Genetic engineering was used to introduce the "mothers’ milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.

As an adult, the cloned cow "will produce milk that is similar to that of humans", which will prove "a development of great importance for the nutrition of infants(婴儿)", said the institute. "The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk," said the statement.

In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more closely resemble that of humans.

“Our goal was to raise the nutrition value of cows’ milk by adding two human genes, which do good to the immune system of infants,” said Adrian Mutto, from the National University of San Martin which worked with the institute.

Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud. She also said that she had refused the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita.”

1.What is the passage mainly about?

A. The importance of genetic engineering.

B. Ways to improve mothers’ milk.

C. Advanced agricultural technology in Argentina.

D. A cloned cow to produce human-like milk.

2.Which of the following can best replace “more closely resemble” in Para 4?

A. have more varieties than

B. have more nutrition than

C. be more similar to

D. be more different from

3.What can be inferred from Cristina Kirchner’s statements?

A. She was quite satisfied with the research done by the institute.

B. She considered it an honor to name the special cow.

C. She felt it improper to be named after the cow.

D. She refused to give a name to the cow out of self-respect.

4.What’s Adrian Mutto’s attitude to the genetic engineering?

A. negative　　 B. supportive

C. indifferent　　 D. mixed

Scientists have created a “ human-like robot” that can dance and do the housework.

“ Mahru” has been developed to imitate humans and can move its lips, eyebrows and pupils(瞳孔). The machine can also move its upper and lower body freely and automatically stop itself when walking.

In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions.

The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind.

“‘Mahru’ will open the way for the commercial use of humanoid robots doing housework,” You Bum-Jae, leader of the development research team ,said. “‘Mahru’ can dance while walking on its legs and is able to work in place of a human.”

Through an advanced motion capture (捕获) system, “Mahru” can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking.

State-funded KIST showed the robot during a presentation at its head office in Seoul.

People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves.

The research team added that they had designed another “ Mahru”, this time with sensors(传感器) allowing it to distinguish(分辨) between faces and objects.

The showing of “ Mahru” came a week after researcher in Japan said they had created the “most human-like” robot in the world. A team at robotics department of Osaka University in Japan claimed that “ robogirl”, Repliee R-1, “ looks, moves and interacts (相互作用) like a human, and has silicone(硅胶) skin that feels almost human to the touch.”

1. “Mahru” made by KIST can do the following things EXCEPT____________

2. According to what You Bum- Jae said in Paragraph 5, his research team wants to ________.

3. When Mahru” meets something in its way, it will be likely to________.

4.According to the last paragraph, Repliee R-1 __________.

5.The passage is probably a  __________.

Scientists have transformed men’s minds into a virtual（虚拟的）woman’s body in an experiment that could throw light upon how humans distinguish themselves form others.

In a study at Barcelona University, men wore a virtual reality headset that allowed them to see and hear the world as a female character. When they looked down, they could even see their new body and clothes.

The “body－swapping” effect was so convincing that the men’s sense of self was transferred into the virtual woman, causing them to react to events in the virtual world they were immersed（沉浸）. “This work opens up another avenue for virtual reality, which is not just to transform your sense of place, but also your sense of self,” said Mel Slater, “If you can temporarily give people the illusion that their bodies are different, then the evidence suggests it also affects their behavior and the way they think. They can have new experiences: a person who is thin can know what it is like to be fat. A man can have an experience of what it’s like to be a woman.”

During the experiment, a “female” approached and hit the face of the character another man was playing. “Their reaction was immediate,” said Slate. “They would take in a quick breath and maybe flinch（退缩）. The more people reported being in the girl’s body, the stronger physical reaction they had.” But in all cases, the feeling was temporary and lasted only as long as the study.

The study shows that our minds have a very fluid picture of our bodies. The research is expected to shed light on the puzzle of how our brain tells the difference between a part of our own body and something else in the wider world. Thus the work might improve the conditions for those who have experienced strokes by placing them in a world that helps them to use their bodies to the full again.

1.How can a man’s mind get into a woman’s body?

A．by distinguishing themselves from women

B．by taking part in an activity actively

C．by wearing a special device（设备）

D．by transforming his sense of place

2.Of the following statements, which we can’t infer from the passage?

A．Men in the experiment can temporarily have the wrong feeling that they are women.

B．When hit, the men in the virtual world will react angrily to it.

C．As soon as the experiment is finished, the men will return to the normal state

D．Probably, this study can be applied to medical fields and benefit humans.

3.What is the author’s intention of writing this passage?

A．to introduce an interesting and advanced study

B．to inform us of the latest development of virtual reality

C．to illustrate the importance of virtual reality

D．to build up our confidence to fight stroke

As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone.

Scientists in London say they have found the best diet for both humans and the planet. If the world followed the so-called "planetary health" diet, the scientists told Reuters that each year more than 11 million early deaths could be prevented. Scientists say that the way we produce and eat food is very bad for the planet. For the health of the planet, they claim the same diet would reduce greenhouse gases and save more land, water and animals.

Tim Lang, a professor at Britain's University of London, co-led the research. He told Reuters, "The food we eat and how we produce it determines change what we eat and the way we eat by "improving food production and reducing food waste."

Well, what do you eat on the planetary health diet? The scientists who created this diet say it is largely plant-based but still has small amounts of dairy, fish and meat. The diet calls for cutting red meat and sugar by 50 percent and doubling the amount of nuts, fruits, vegetables and legumes.

Food situations around the world are not equal. In certain areas, this would mean great changes. People in North America, for example, eat 6.5 times the recommended amount of red meat. On the other hand, people in South Asia eat only half the amount suggested by the new planetary health diet. Meeting the targets for vegetables would need big changes in other areas. In sub-Saharan Africa, people on average eat 7.5 times the suggested amount of vegetables like potatoes and cassava.

The scientists admit their goal will be difficult to achieve. But for them doing nothing is also not an option. Willet said, "If we can't quite make it, it's better to try and get as close as we can."

The human brain remembers negative experiences more easily than positive ones. Our brains have developed in this way because threats, like dangerous animals, have a more immediate effect on people’s survival compared to positive things like food or shelter. As a result, you clearly know what makes you unhappy, but do you know what makes you happy?

Research suggests that our level of happiness is partly shaped by the choices we make. If you’ve been chasing wealth, fame, power and some material things, you may be looking for happiness in the wrong places. Psychologists suggest that the following habits can make people happier.

People who own close relationships tend to be happier than those who do not. The number of our friends is not important. What matters is the quality of our relationships. Relationships that bring happiness usually consist of the sharing of feelings, acceptance, mutual (双方的) respect and trust.

People who exercise regularly can improve both their physical and mental well-being. Some research has shown that exercise can be as effective as some medicine in treating depression.

If we are so interested in an activity, we may lose track of time, and we can be in a state of flow. The activity could be playing the piano, surfing the Internet or playing a game… People who experience flow in their work or life tend to be happier.

People are more likely to be happy if they know what their strengths are and can use them regularly. People are especially happy when they can set goals and use their strengths to achieve them.

People, who think positively by being grateful, mindful and optimistic, are more likely to be happy. Being grateful means being thankful. Being mindful means considering, focusing on, and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

1.Human brains remember negative things more easily because negative things____ .

A. tend to affect human survival immediately

B. are much more important than other things

C. can make people live much happier

D. are easy to remember

2.According to this passage, people may find happiness in___ .

A. being famous　　 B. chasing power

C. setting life goals　　 D. earning money

3.In the last paragraph, the author tries to tell us to ____.

A. think more about our future　　 B. be positive in our life and work

C. focus on everything in our life　　 D. only enjoy the present moment

4.What does the passage mainly want to tell us?

A. Why people remember positive things easily.

B. Why people remember negative things easily.

C. What makes people happy.

D. What makes people sad.
