People often say that “failure is the mother of success”. 1. As a result, Manalo, a professor of educational psychology in Japan says, “We know we shouldn’t give up when we fail—but in reality, we do.”

Manalo and Manu, a professor of learning sciences in Swiss, put together a special issue (专利) last December on benefiting from failure. The issue’s 15 studies provide teachers and educational researchers with a guide for achieving success. 2. Another confirmed that advice on failures is most constructive when the receiver is prepared to experience unpleasant feelings.

Manalo and his co-authors also focused on overcoming one everyday form of failure: not completing a task. They asked 131 students to write an article about their school experiences. Half of the students received instructions for their writing, and half were left to their own. 3. Afterward the researchers found that those in the instructed group were more willing to complete their articles, compared with those who lacked guidance—even if the latter were closer to being done. 4.

5. Stephanie Couch, the director of the Lemelson-MIT Program, holds the opinion. Couch, whose work was also featured in the special issue, says that we should tell them to think of failure as part of a process toward success.

A.However, all were stopped before finishing.

B.The saying shows the importance of success.

C.Teaching students not to fear failure makes goals achieved more easily.

D.One study reported that the sooner students fail, the sooner they can move forward.

E.Though having some truth to it, the saying does not tell us how to turn a loss into a win.

F.They believed that learning how to fail can help people avoid becoming lasting failures.

G.Knowing how to finish, in other words, was more important than being close to finishing.

United States health officials say an estimated 80,000 people died of influenza (流感) and problems resulting from the flu last winter, making it the worst season since 1977. The director for the U.S.Centers for Disease Control and Prevention (CDC) reported the number to The Associated Press. Health experts were expecting the winter of 2017-2018 to be a bad year for flu deaths, but not that.

Doctor William Schaffner is an expert on vaccines,　 at Vanderbilt University in Tennessee. Schaffner noted that 80,000 deaths are nearly twice as much as what health officials once considered a “bad year”.

CDC officials say that between 12,000 and 56,000 Americans die every year from flu-related causes, but they do not have an exact count of how many people die from the flu each year. Influenza is a relatively common disease and not always listed on death records as the official cause of death. While last winter was a bad flu season in the U.S., it was not the worst. The 1918 flu lasted nearly two years. Historians estimate that the disease was to blame for between 500,000 to 700,000 deaths during that period. The exact number is still not known.

One thing that made the 2017-2018 flu season so bad was that the flu virus was strong. Usually the disease kills the very young, the very old or those who are already sick. However, last winter, the flu killed many healthy Americans. Another thing that made the flu season so deadly was that the flu vaccine was not as effective as experts had predicted. Drug makers have made changes to the vaccine. Even though the vaccine did not work well last year, health experts still strongly suggest getting vaccinated.

1.What can we learn about influenza in the first paragraph?

A.The winter of 2017-2018 saw the deadliest flu in history.

B.Effective cures should be found to deal with influenza.

C.Health experts had assumed flu would be severer.

D.More people died of influenza than expected in the winter of 2017-2018.

2.How many deaths did the health officials expect in a bad year?

A.80,000. B.40,000.

C.60,000. D.20,000.

3.Why can't CDC officials give an exact number of deaths from flu?

A.Because flu is always considered as a common disease.

B.Because people usually don't take flu seriously.

C.Because CDC officials are unwilling to count the deaths.

D.Because flu is not always listed on death records.

4.What do experts recommend people to do in the last paragraph?

A.Change the vaccine. B.Avoid using vaccine.

C.Get vaccinated. D.Do research on vaccine.

Every year, 1.5 million kids around the world die as a result of not getting vaccines (疫苗). This is partly because transporting and storing medicines can be a huge challenge in some countries.

Anurudh Ganesan, 17, knows this firsthand. When he was a baby in India, his grandparents carried him 10 miles to a health clinic in a remote village to receive a vaccine. But by the time they arrived, the vaccines were no longer usable because they had been overheated.

Vaccines, Anurudh later learned, must be kept cool to stay effective. But refrigerating them requires electricity or ice – precious resources that many developing countries lack.

Although Anurudh eventually received the vaccine he needed, his experience as a baby and the sad reality that so many other children aren’t as lucky motivated him to take action. The high school student invented Vaxxwagon, a portable vaccine-carrying device that generates its own power to keep lifesaving medicines cool as they’re delivered to remote areas around the world.

Anurudh first got his idea for Vaxxwagon in 2014. He read several textbooks to learn everything he could about refrigeration, and then he did research online to learn more about vaccines. Rather than relying on electricity or ice, Anurudh figured out a way to use wheels to power a refrigeration system for about eight hours. The entire rechargeable cooling system can be pulled to areas in need of vaccines by a bicycle, a car, or an animal. Eventually, Anurudh took his design to professors at Johns Hopkins University for advice. Not only did they confirm Vaxxwagon could work, but they offered him funding to help build it.

Anurudh was rewarded with the 2015 Google Science Fair LEGO Education Builder Award for his invention. Anurudh says his final goal is to start selling Vaxxwagon to relief organizations, so it can be used to help people around the world.

Anurudh, who plans to pursue engineering degree in college, says, “Don’t give up on your ideas. But always try to help others with your projects. That’s the point of engineering – to help people.”

1.Why do many children die every year?

A. They lack qualified medical teams.

B. They cannot afford usable medicines.

C. They don’t have an electricity system.

D. They have no access to effective vaccines.

2.What is special about Vaxxwagon?

A. It can serve as a fridge.

B. It can produce safe vaccines.

C. It can detect deadly diseases.

D. It can be a means of transport.

3.Which of the following words can best describe Anurudh?

A. Caring and creative.

B. Modest and sympathetic.

C. Loyal and determined.

D. Honest and hard-working.

4.What can we learn from the story?

A. Practice makes perfect.

B. One good turn deserves another.

C. Motivation is the mother of success.

D. All things are difficult before they are easy.

高三英语单项填空简单题查看答案及解析

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag(时差). People with jet lag feel extremely tired for several days. They may also have problems in thinking clearly and remembering.

Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.

The researcher took some saliva (唾液) from the women’s mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain’s temporal lobes (脑叶).

It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction on the visual memory test. And their saliva samples showed higher levels of stress hormones.

The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.

Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently affect memory.

1.It can be inferred from the text that ______.

A. the conclusion is refused by many scientists

B. scientists fear that this research is not done properly

C. every scientific conclusion needs the support from many tests

D. the women who were examined in the research were not healthy

2.From the result of the research we can see that _____.

A. the women who have longer rest at home perform better on the test.

B. the women who fly in short time have smaller right temporal lobes

C. the women who have longer flights fail the memory test

D. the women who rest more than 14 days produce more hormones

3.What is the subject discussed in the test?

A. The cause of jet lag.

B. A story of a group of flight attendants.

C. The importance of having enough rest after flights.

D. A research about the effects of jet lag on the brain

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. Jet lag interferes with a person's normal times for sleeping and waking. People with jet lag may feel extremely tired for several days. They also may have problems thinking clearly and remembering.

Kwangwook Cho is a researcher at the University of Bristol in Britain. He reported the findings of his jet lag study in the publication Nature Neuroscience.

The study involved twenty young women who worked for international airlines. The women had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.

Mister Cho took some fluid from the women's mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains using magnetic resonance imaging. This is a way to measure the size of the brain's temporal lobes（颞叶）.

It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
