21、 For many Daylight Saving Time (DST:夏令时) simply means remembering to change the clocks and twisting your sleep schedule. “Even though the time change is only an hour, it is something that causes much more destruction than people believe,” said Dr. John Sharp, a psychologist and psychiatrist at Beth-Israel Deaconess Medical Center in Boston. “It’s not just an extra hour of sleep; it’s more of a fast-forward into winter.”
With days getting darker earlier, Sharp suggests making a to-do list for activities after work ahead of time. “Any plans you have, say, going to the gym after work, require much more effort and determination. It’s much better to plan more carefully and not just rely on how you feel, especially when it is dark out,” he said. “Figure it out in advance and stick with the plan.”
In addition. Sharp says in the weeks after Daylight Saving, some may feel like they have a bigger appetite. “Eating more during this time is not the answer. People need to stay on an eating schedule and keep up healthy habits. ”
However, Sharp said there are ways to better acclimate yourself to the time change. If you are having trouble sleeping, he suggests taking some melatonin (退黑激素) in the evening. In contrast, if you find yourself feeling sleepy. Sharp said there is nothing wrong with adding an extra caffeinated drink during your day.
A word to the wise? One sure way to better adjust to the time change is to start going to bed 15 minutes earlier starting four days before Daylight Saving, adding an additional 15 minutes each night.
【1】Which is probably the best title for the passage?
A.Are you prepared for DST? B.Why DST was introduced?
C.What DST has brought to life? D.How DST has been popular?

A.Getting up earlier than before. B.Sticking to the daily routine.
C.Being aware of quality sleep. D.Getting well-prepared for DST.
【3】The underlined word “acclimate” in Paragraph 4 can be replaced by______.
A.adopt B.accelerate
C.adapt D.acknowledge
【4】The passage is probably taken from______.
A.a scientific report B.an interview
C.a speech D.a statement
22、When whales die and sink to the ocean floor, their bodies -known as whale falls -provide rich nutrients for other creatures of the deep.
Chinese scientists found a whale fall in the South China Sea during a recent scientific research voyage. It was the first time that Chinese researchers had run across this rare type of ecosystem. It was an important finding, showing China's progress in deep-sea exploration technology, Xie said, a professor at Sun Yat-sen University.
During the 22-day deep-sea exploration from March 10 to April 2. 60 scientists conducted 22 dives and successfully completed a number of scientific tasks. The research aimed to gather information about the key processes of typical seamount ecosystems in the Western Pacific: Ocean. The whale fall was found in a seamount 1,600 meters deep in the central South China Sea. Though the whale fall was only about 3 meters long, it was of great importance in understanding the sea ecosystems, Xie said.
There were dozens of white armored shrimp, red shrimp and several eels found near the whale fall. The eels were eating the tail muscles of the whale fall. This shows that the whale died not long ago and that the whale fall was still in the first stage of decomposition and thus had rare value for long-term observation, Xie said.
Like cold springs, whale falls are homes for creatures of the deep. In the northern Pacific Ocean, they have supported the survival of at least 12,490 kinds of organisms—classed in 43 species—and promote prosperity far beneath the surface, according to data from the university.
【1】What do we know about the whale fall in the South China Sea?
A．It is found on March 10.

D．It is found 3 meters deep in the sea.
【2】How is the Paragraph 3 organized?
A．By giving data.
B．By giving examples.
C．By giving definitions.
D．By making a contrast
【3】What does the underlined word "prosperity" in the last paragraph probably mean?
A．Change
B．Disappearance.
C．Richness.
D．Tourism.
【4】What does the text mainly tell about?
A．A deep-sea exploration led by China.
B．A whale fall found in the South China Sea.

23、 Most people aren’t good at creative problem solving for two reasons: (1) They are not trained in how to be creative. (2) They don’t understand group strength well enough to harness（驾驭）their power to maximize group creativity.
A key element of creativity is applying existing knowledge to a new problem. The more people getting involved in solving it, the more knowledge there is to work on it. Unfortunately, research shows that the traditional brainstorming methods fail to achieve that goal. When groups get together to exchange ideas, they actually come up with fewer ideas overall than if they each had worked alone.
To fix this problem, you should consider the two stages of group problem-solving: divergence（分散）and convergence（集中）. Divergence happens when the group considers as many different potential solutions as possible. Convergence happens when the various proposed solutions are evaluated and reduced to a smaller set of candidate solutions to the current problem.
The essential principle of group creativity is that individuals working alone diverge, whereas group members working together converge. In groups, once a member states a potential solution, that makes others think about the problem similarly. That is why groups working together diverge less than individuals working alone.
Therefore, be aware of when to diverge and when to converge. For example, early in the problem-solving process, have group members work alone to write down statements describing the problem. Then get them back to discuss their descriptions. The group discussion will lead everyone to accept one or a small number of these statements to work on—this is healthy convergence.
When starting to generate solutions, you again want divergence. Have people work alone to start. Then collect people’s initial ideas and send them around to others and allow the divergence to continue as everyone individually builds on the ideas of other members.
Finally, let the group discuss the resulting ideas. This discussion will gradually lead the group to converge on a small number of candidate solutions.
This simple method works effectively, because it respects what individuals and groups do best.
【1】Research shows that the traditional brainstorming methods ______.
A.actually limit group creativity
B.greatly encourage group creativity
C.enable people to form more ideas together
D.prevent people’s involvement in the problems
【2】According to Para. 4, when a member presents an idea, others tend to_____.
A.think the other way round
B.follow his way of thinking
C.be more confident in their own ideas
D.be less willing to share their own ideas
【3】What should group members first do early in the problem-solving process?
A.Discuss the problem. B.Simplify the problem.
C.Put down group statements together. D.Write down their individual descriptions.
【4】How can each group member make changes to his initial solution?
A.By adding in collected evidence. B.By reorganizing his own words.
C.By drawing on others’ ideas. D.By making his statement briefer.
【5】What is the author’s purpose in writing the passage?
A.To advocate a way to make group thinking more effective.
B.To demonstrate the difficulty in organizing group thinking.
C.To highlight the differences between divergence and convergence.
D.To show the advantage of group thinking over individual thinking.
24、The first solar cell capable of powering everyday electrical equipment was made in the 1950s at Bell Labs in New Jersey. Back then the silicon-based (基于硅的) panels were hugely expensive and turned just 6% of sunlight into electricity. Since then, costs have come down dramatically and today’s silicon solar cells can tur up to 22% of sunlight into power. But they’re nearly maxed out in terms of efficiency. Now, perovskites (钙钛矿) offer the potential for dramatic increases in power output, and they could ultimately replace silicon altogether.
Rescarchers at Oxford PV, a company spun out of the University of Oxford, made a major breakthrough in 2018. By coating silicon with perovskites they achieved 28% efficiency. The company believes it can eventually reach 40%, or higher. “If we want to make all new power generation about solar photovoltaics (光伏), then we need to keep driving the price down,”Henry Snaith, professor of physics at the University of Oxford and co-founder of Oxford PV,said.“One way to do that is to keep pushing the efficiency or power output up, and this is where perovskites really come into play.”
Perovskites were discovered in 1839. Oxford PV uses a synthetic (合成的) version,made from inexpensive materials that are present on the Earth in large quantities, while other companies use variations of the original mineral,collectively called perovskites. As well as improved solar efficiency, they work better than silicon in the shade, on cloudy days or even indoors. Perovskites can be printed using an inkjet (喷墨的) printer and can be as thin as wallpaper. Oxford PV hopes perovskites will eventually replace silicon entirely.
Last month, Saule Technologies’new factory in Warsaw began printing perovskite solar cells using inkjet printers. Early next year, it will start supplying Swedish construction company Skanska Group.“The material is set to be a game changer in the energy field, because it works in every lighting condition,”said Saule Technologies co-founder Olga Malinkiewicz.
【1】What is the biggest disadvantage of silicon-based panels?
A．They are incredibly expensive.
B．They are easy to abandon totally.
C．They are relatively low in power output.
D．They have only existed for about 50 years.
【2】What attitude does Snaith have towards perovskites?
A．Favorable.
B．Cautious.
C．Opposed.
D．Ambiguous.
【3】Why can perovskites possibly replace silicon entirely?
A．They can be as thin as paper.
B．They are rarely seen on the Earth.
C．They can be printed with 3-D printers.
D．They perform well in poor lighting conditions.
【4】What can be a suitable title for the text?
A．The cost of perovskite solar cells.
B．A new way to replace perovskites.
C．The applications of solar photovoltaics.
D．A potential way to increase solar power output.

26、阅读下面材料，根据其内容和所给段落开头语续写两段，使其构成一篇完整的短文。续写的词数应为150左右.
Robert and Henry were two friends in the same class. They always played together and went home together. One day Robert and Henry were going home from school, when, on turning a corner, Robert cried out, “A fight! Let’s go and see!”
“No,” said Henry. “Let us go quietly home and not meddle with(插手) this quarrel. We have nothing to do with it and may get into mischief(trouble). Also our parents are expecting to have dinner with us together at home and I don’t want them to worry about me. ”
“You are a coward, and afraid to go,” said Robert, and off he ran. Henry went straight home, and in the afternoon went to school as usual.
But Robert had told all the boys that Henry was a coward, and they laughed at him a great deal. From then on, they looked down upon Henry and didn’t want to play with him together.
Henry was sad but he wasn’t angry with Robert for his rude behavior, because he learned that true courage is shown most in bearing misunderstanding when it was not deserved, and that he ought to be afraid of nothing but doing wrong. Thus, he just ignored the other boys’ laughter and continued to go to school and study as well. However, Robert didn’t invite Henry to go home with him anymore. Instead, he had some other boys who also thought Henry was a coward. Every day after school, they didn’t go home directly but went to the river or somewhere to play games and had a lot of fun.
A few days later, Robert was bathing with his new friends in a river, and got out of his depth. He struggled, and screamed for help, but all in vain. The boys who had called Henry a coward got out of the water as fast as they could, but they did not even try to help him.
