Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.

In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today,　 Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.

From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

1.We know from the passage that elephants may be frightened of 　　　　　 .

A. loud noises　　 B. some crops

C. video cameras D. angry bees

2.As mentioned in the passage, Lucy

A. works by herself in Africa

B. needs to test more elephant groups

C. has stopped elephants eating crops

D. has got farmers to set up beehives on their farms

3.Why did Lucy throw a stone into a wild beehive?

A. To record the sound of bees.

B. To make a video of elephants.

C. To see if elephants would run away.

D. To find out more about the behavior of bees.

4.Which of the following is true according to the passage?

A. Young elephants ignore African honeybees.

B. Waterfalls can make elephants stay in one place.

C. Elephants do not go near trees with bees living in them.

A new study finds that young females in one group of African chimps(黑猩猩) use sticks as dolls more than their male peers (同龄) do, often treating pieces of wood like a mother chimp caring for a baby. In human cultures around the world, girls play with dolls and pretend that the toys are babies far more than boys do.

Chimp observations, collected over 14 years of field work with the Kanyawara chimp community in Kibale National Park in Ugandan, provide the first evidence of a nonhuman animal in the wild that exhibits sex differences in how it plays. This finding supports an argument that biology as well as society underlies boys’ and girls’ different toy preferences.

Stick play occurred most commonly between ages 3 and 9. Females spent a lot more time carrying sticks than males did. Young male chimps occasionally used sticks to mimic(模仿) childcare. “Far more often, they fought with sticks, an infrequent behavior among females,” say Sonya Kahlenberg of Bates College in Lewiston, Maine, and Richard Wrangham of Harvard University.

“Biological differences between the sexes make female chimps more receptive to stick-mothering than males,” says Wrangham.

Consistent with reported cultural traditions among adult chimps, Kanyawara youngsters learned from each other to play with sticks as if caring for babies. Stick play among young chimps showed no evidence of being directly influenced by older chimps. Child-bearing females never played with sticks and thus didn’t model such behavior for younger chimps.

Young females carried sticks for anywhere from a few minutes to several hours. They often rested in nests with their sticks, sometimes playing with them much as chimp mothers play with their babies though they didn’t get any form of teaching from the adults.

1.What does a stick seem like to a young female chimp who plays with it?

A. A doll.　　 B. A mother.　　 C. A baby.　　 D. A toy.

2.We can see from the text that young female chimps ________.

A. often carry sticks with males

B. always carry sticks with males

C. never use sticks in fighting

D. seldom use sticks in fighting

3.From whom do the young chimps pick up the stick play behavior?

A. From each other.　　 B. From older chimps.

C. From their mothers.　　 D. From male chimps.

4.What does the text mainly tell us about young chimps’ stick play?

A. The types of stick play and social influence.

B. The sex differences and social influence.

C. The sex differences and age differences.

D. The ways of stick play and age differences.

Dreaming is believing, claim researchers of a new study, who found that dreams have an effect on people’s behavior, judgment and they might contain important hidden truths as well.

“Psychologists’ explanations of the meaning of dreams vary widely. But our findings show that people believe their dreams provide meaningful insight into themselves and their world,” said a lead author of the study Carey Morewedge, an assistant professor at Carnegie Mellon University.

In six different studies, researchers surveyed nearly 1,100 people about their dreams. One of the studies focused on general beliefs about dreams and involved 149 university students. All students were asked to rate different theories about dreams. The experts found that a surprising majority of the participants supported the theory about dreams revealing (揭示) the hidden truths about themselves and the rest of the world.

In a second experiment, they surveyed 182 people at a Boston train station, and asked them to imagine one out of four possible situation that could have occurred the night before a scheduled airline trip. Most of the participants said that dreaming of a plane crash would be more likely to affect their travel plans than would just thinking about a crash, or being warned by the government of a terrorism risk. They said a dreamed crash would influence their travel plans just as much as learning about a real crash on their planned route would.

Another experiment involved 270 men and women from across the United States. In a short online survey, they were asked to recall one of the dreams they had seen about any person they knew.

The findings showed that people were more likely to remember and describe pleasant dreams about a person they liked, rather than a person they disliked. Meanwhile, in most cases they tended to consider an unpleasant dream as more meaningful if it was about a person they disliked.

“In other words,” said Morewedge, “people attribute meaning to dreams when it corresponds (与……一致) with their pre-existing beliefs and desires.”

The researchers say that more investigation is needed to fully understand how people interpret their dreams. According to Morewedge, most people realize that dreams are not predicting their future, but they still try to find some meaning in there.

1.. The purpose of the studies is to ________.

A. determine when people tend to remember their dreams

B. research whether dreams have anything to do with real life

C. find out how people explain their dreams and what impact that has

D. understand what causes people to dream and how to interpret dreams

2. According to the second experiment, what might influence people’s travel plans most?

A. Thinking about a past plane crash.

B. Dreaming about a plane crash.

C. Hearing a government’s warning of a terrorism risk.

D. Imagining a plane crashing on their planned route.

3.. What can be concluded from the study?

A. Dreams can be a useful tool for learning and problem solving.

B. Most people disagree that dreams help them better know themselves and the world.

C. A majority of people believes that dreams can predict their future and try to find their meaning.

D. When a dream conflicts with people’s existing beliefs and desires, they tend to attribute less meaning to it.

4.. Which kind of dream is seen as more meaningful than the rest?

A. A pleasant dream about a person the dreamer likes.

B. A pleasant dream about a person the dreamer dislikes

C. An unpleasant dream about a person the dreamer likes.

D. An unpleasant dream about a person the dreamer dislikes.

A new study, a project of the researchers from the University of Pittsburgh in Pennsylvania, finds the fitness tracker probably does not help with weight loss.

The devices are designed to record your physical activity. They are usually worn around the wrist, where they measure a person’s heart rate. The research team looked at two groups of individuals. The first wore a fitness tracker and took part in health counseling (咨询) with experts to consider the best weight-loss plan. The researchers compared this group with people who only got health counseling.

The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic, the lead researcher, questioned the use of electronic devices for weight control in place of “effective behavioral counseling for physical activity and diet. ”

The study involved 470 subjects aged between 18 and 35. Some of them were overweight, while others were considered obese (肥胖的). Over three fourths of the subjects were women. All the subjects were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a fitness tracker. Eighteen months later, both groups “showed significant improvements in fitness, physical activity, and diet,” with no major difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.

Jakicic said, “the study’s findings are important because effective long-term treatments are needed to address America’s obesity. ” More information is needed, he added, to learn how to best use these devices to change “physical activity and diet behaviors” in adults who want to lose weight.

1.All the subjects in the study were asked to ________.

A. start on a high-calorie diet　　 B. wear a fitness tracker

C. increase physical activities　　 D. record their heart rates

2.Why does Jakicic think the findings are important?

A. Wearing fitness trackers hardly helps people lose weight.

B. Physical activity and diet have no effect on weight loss.

C. Handling obesity requires effective long-term treatments.

D. There are great differences in fitness between both groups.

3.What can we infer about the study mentioned in the text?

A. The study went on for about two years.

B. More than 120 men took part in the study.

C. Health counseling helps lose almost 6 kilograms.

D. Wearing a fitness tracker is useful for keeping slim.

4.The purpose of the text is to ________.

A. describe how the researchers were conducting the study

B. indicate regular counseling for weight control is necessary

C. convince readers to wear fitness trackers for weight control

D. warn women are more likely to suffer from weight problems

Elephants have four distinct personalities that help their herd survive in the African bush, scientists have found.

With their grey skin, mournful eyes and slow heavy pace, you could be forgiven for thinking elephants are uniformly melancholy(忧郁的) creatures. But scientists have now discovered the largest living land animals have personalities to match their size.

In a new study of African elephants, researchers have identified four distinct characters that are common in a herd – the leaders, the gentle giants, the playful rogues(小淘气) and the reliable plodders (辛勤工作的人).

Each of the types has developed to help the giant mammals survive in their harsh environment and is almost unique in the animal kingdom, according to the scientists.

Professor Phyllis Lee and her colleague Cynthia Moss studied a herd of elephants in the Amboseli National Park in Kenya known as the EB family — famous for their matriarch Echo before she died in 2009.

Using data collected over 38 years of watching this group, the researchers analyzed them for 26 types of behavior and found four personality features tended to emerge.

The strongest personality to emerge was that of the leader. Unlike other animals, where leadership tends to be won by the most dominant and aggressive individual, the elephants instead respected intelligence and problem solving in their leader. Echo, the matriarch and oldest in the group, her daughter Enid, and Ella, the second oldest female, all emerged as leaders.

The playful elephants tended to be younger but were more curious and active. Eudora, a 40-year-old female in the herd, seemed to be the most playful, consistently showing this feature throughout her life while playfulness in some of the other elephants declined with age.

Gentle elephants, which included two 27-year-old females Eleanor and Eliot, touched and rubbed against others more than the others.

Those that were reliable tended to be those that were most consistent at making good decisions, helped to care for infants in the herd and were calm when faced with threats. Echo and her youngest daughter Ebony seemed to be the most reliable.

Professor Lee said that elephants with these features tended to be the most socially integrated in the group while those who tended to be less reliable and pushy were more likely to split from the herd.

1.From the passage we get to know that ________.

A．the researchers reached their conclusion by analyzing the data

B．the research centered on the 26 types of behavior of the matriarch

C．the scientists conducted the research by comparing elephants with other animals

D．professor Phyllis Lee and her colleague spent nearly 38 years tracking the herd

2.According to the new findings of the scientists, ________.

A．playfulness of an elephant will always decline with age

B．those elephants which are caring and wise are most reliable

C．each elephant can be matched with only one of the four personalities

D．once becoming a member of a herd, an elephant will never split from it

3.In the EB family Echo and Eudora are ________.

A．mother and daughter                    B．two oldest females

C．the gentlest ones                       D．leader and member

Protests (抗议) at the use of animals in research have taken on a new and fearful character in Britain with the attempted murder of two British scientists by the terrorist (恐怖分子的) technique of the pre-planted car–bomb .

The research community (社团) will rightly be alarmed at these developments which have two aims :to draw public attention and to frighten people working in research with animals . The scientists insist that everything should be done to identify those responsible for the crimes and to put them on trial . The Defense Research Society has taken the practical step of offering a reward of £10，000 for information leading to those responsible , but past experience is not encouraging . People are unlikely to be attracted by such offers . The professional police will similarly be challenged by the problem of finding a needle in a haystack .

That is why the intellectual (知识分子) community in Britain and elsewhere must act more strongly in its own defense . There are several steps that can be taken , of which the chief one is to demand of all the organizations that exist with the declared aims of defending the interests of animals that they should declare clearly where they stand on violence towards people . And it will not be enough for the chairman and chairwoman of these organizations to make placatory (安抚的) statements on behalf of all their members . These people should also promise that it will be a test of continuing membership in their organizations that members and would-be members should declare that they will take no part in acts of violence against human beings .

67．The words “these developments” (Linel , Para .2 ) most probably refer to ________ .

A．the use of animals in research

B．the acts of violence against scientists

C．the techniques of planting bombs in cars

D．setting up of new animal protection organizations

68．Which of the following is true according to the passage ?

A．The police gave up their efforts to find the criminals .

B．The terrorists escaped with the help of their organization .

C．The attempted murder caused great anxiety among British scientists .

D．People supported the animal protectors in spite of their extremist acts .

69．The author’s purpose in writing this article is to demand that animal-protecting organizations ________ .

A．give up the use of violence

B．declare their aims clearly

C．continue the dialogue with the scientific community

D．help to fid those responsible for the attempted murder

70．In the author’s opinion ,________ .

A．animal-protecting organizations should be declared illegal

B．the scientists should take effective measures to protect themselves

C．since people can lie , the problem about eh rights of scientists can’t be solved

D．animal-protecting organizations should help the police to fight against the acts of violence

against scientists
