21、 You feel especially smart and funny when talking to a particular person, only to feel hopelessly unintelligent and tongue-tied in the presence of another.
Experiments show when people report feeling comfortable with a conversational partner, they are judged by those partners and by observers as actually being more witty (机智的）。
It's just one example of the powerful influence that social factors can have on intelligence. As parents, teachers and students settle into the school year, this work should encourage us to think about intelligence not as a “lump of something that's in our heads,” as the psychologist Joshua Aronson puts it, but as “a transaction among people.”
Mr. Aronson, an associate professor at New York University, has been a leader in investigating the effects of social forces on academic achievement. Along with the psychologist Claude Steele, he identified the phenomenon known as “stereotype (刻板印象） threat.” Members of groups believed not to be academically good score much lower on tests when reminded in advance of their race or gender.
The pair's experiments in the 1990s concluded that the performance of these students suffered because they were worried about confirming negative stereotypes about their group.
Minorities aren't the only ones easily hurt by stereotype threat. We all are. A group of people especially confident about their mathematical abilities did worse on a math test when told that the experiment was intended to investigate “why Asians appear to perform better than other students on tests of math ability.”
And in a study published earlier this year in the journal Learning and Individual Differences, high school students did worse on a test of spatial (空间的） skills when told that males are better at solving spatial problems because of genetic differences between males and females. The girls were anxious about confirming assumptions about their gender, while the boys were anxious about living up to them.
The evolving literature on stereotype threat shows that performance is always social in nature. Even alone in an exam room, we hear a chorus of voices assessing, evaluating, passing judgment. And as social creatures, humans are strongly affected by what these voices say.
【1】What does the underlined word “transaction” in paragraph 3 refer to?
A.Spatial reasoning skills. B.The ability to remember information.
C.Interaction between us and the environment. D.Passing on knowledge from teachers to students.
【2】After being told males typically perform better than females in math, males are most likely to perform .
A.better than females B.the same as females
C.worse than usual D.worse than females
【3】Which of the following “voices” in our head may influence performance on an exam?
A.“I am as prepared as I can be.”
B.“I am supposed to do well on this.”
C.“The testing room is different from my classroom.”
D.“I am solving the problems faster than the one sitting in front of me.”
【4】How do stereotypes threaten our academic achievement?
A.Making us unintelligent. B.Reminding us of our weaknesses.
C.Limiting our spatial reasoning skills. D.Raising our anxiety level.
22、If you choose only to complain and escape from a misfortune, it will always follow you wherever you go. But if you decide to be strong, the hardship will turn out to be a fortune on which new hopes will arise.
In an accident, a boy lost both his arms and his father------who was the main source of support for the family. Since then, he has had to depend on the arms of his younger brother. In order to take care of him, his younger brother became his shadow, never leaving him alone for years. Except for writing with his toes, he was completely unable to do anything in his life.
As the two brothers grew up together, they had their share of problems and they would often quarrel. Then one day, his younger brother wanted to leave, living his own life, as many normal people do. So he was heart-broken and didn't know what to do.
A similar misfortune happened to a girl, too. One night her mother, who suffered from chronic（慢性的）mental illness, disappeared. Her father went out to look for her mother, leaving her alone at home. She tried to prepare meals for her parents, only to overturn the kerosene (煤油) light on the stove, resulting in a fire which took her hands away.
Though her elder sister who was studying in another city, showed her willingness to take care of her, she was determined to be completely independent. At school, she always studied hard. Most of all she learned to be self-reliant (依靠自己).
One day, the boy and the girl were both invited to appear on a television interview program. The boy told the TV host about his uncertain future at being left on his own, while the girl was full of enthusiasm for her life. They both were asked to write something on a piece of paper with their toes. The boy wrote: My younger brother's arms are my arms; while the girl wrote: Broken wings, flying heart.

23、Iman, the last Sumatran rhino(犀牛) in Malaysia, died in 2019 — bringing the endangered species one step closer to extinction. Now, Malaysian scientists are hoping to use tissues and cells from Iman and other dead rhinos to bring the population back.
“Before the three rhinos (the last survivors in Malaysia) died, we got their cells, and the cells are still alive — which is why I’m quite confident,” Dr. Lokman said. “If we don’ t have any cells, or have just tissue that isn’t living anymore, we wouldn’t be able to do anything. But now we have a living thing that we can use.”
The cells came from the rhinos’ hearts, lungs and brains. What is the most important is that the team collected stem cells (干细胞). One possible approach is to develop these stem cells into an egg（卵子）and sperm (精子), to create an embryo (胚胎) that will be placed into a surrogate mother (代孕母亲). She will likely be another rhino, either a Sumatran rhino from another country or another species. The other method is to take the egg of a surrogate animal, remove the nucleus (细胞核), and join it with a Sumatran rhino’s body cell. This technique was famously used to clone Dolly the sheep in 1996. Dr. Lokman and his colleagues are trying both ways. The team is still in the early stages; next, they need to find a suitable surrogate female.
Sumatran rhinos are listed as critically endangered by the World Wildlife Fund. There are less than 80 alive in Indonesia and Thailand. The fall in the population was first caused by hunting. Later, the situation was worsened by the loss of habitats and human activity. Unfortunately, there are now only five remaining rhino species worldwide, and all are threatened. Some sub-species have already died out; the western black rhino was declared extinct in 2013. And it is a pity that the last male northern white rhino died in 2019.
【1】What makes it possible for the team to bring the Sumatran rhinos population back?
A．They have collected three rhinos living cells.
B．They have carried out similar experiments before.
C．There is a baby Sumatran rhino living in Malaysia.
D．There are still some cells alive in the dying rhino.
【2】What do the two methods have in common?
A．Both have been used for Dolly.
B．Both change the cell’ s nucleus.
C．Both involve a surrogate female.
D．Both rely on the Sumatran rhinos’ stem cells.
【3】What feeling does the author express in the last paragraph?
A．Her admiration for cloning technology.
B．Her satisfaction with the scientists’ efforts.
C．Her disappointment at protection measures.
D．Her deep worry about the rhino population.
【4】What’s the main idea of the passage?
A．Last Sumatran rhino in Malaysia has died.
B．Scientists hope to clone Sumatran rhinos.
C．Stem cells are giving birth to new rhino babies.
D．Sumatran rhinos are listed as critically endangered.
24、 Rushing to work, watching the stock (股票) market drop daily working long into the night on a project, all of these situations can build up stress. Stress in such situations means pressure, conflict, loss of control, and uncertainty. These feelings can lead to a variety of problems. 【1】
What is stress? Stress is your body's physical and psychological response to anything you regard as overpowering. This may be viewed as a result of life's demands, and your lack of resources to meet them. 【2】 This additional energy cannot be destroyed. If not used, it creates an imbalance within your system. Somehow the energy must be channeled into responses to regain a balance.
【3】 Without some stress you would lose your energy for living. You will do well on certain amounts; but too much or too little stress will limit your effectiveness. Ideally, you find your best level of stress---the balance at which you are most motivated.
【4】 It can make you spend your efforts on not being unhappy, rather than on being happy. You can become negatively influenced in your attitudes and feelings about your life more easily.
In addition, medical research estimates as much as 90 percent of illness and disease is Stress-related. 【5】 High blood pressure and heart disease have been linked to stress factors. Most health professionals agree stress can be a contributing factor in making existing medical problems worse.
A．These different attitudes influence a person's reaction to stressful situations.
B．That is why stress such an ugly ring.
C．Stress is a natural part of your life.
D．In each person's life there are uncertainties.
E．When stressed, your body creates extra energy to protect itself.
F．Stress can have a bad effect on your physical functioning and bodily processes.
G．Too much stress influences your daily life.
