26、 In the middle of winter, when snow is falling in many parts of the United States，scientists have sounded a warning to people who plan to spend many hours in the sun this summer. The warming is: The sun's summertime rays are more dangerous than once thought.
A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone in the atmosphere，which protects humans from harmful levels of ultraviolet radiation, will be thinner over the United States this summer. The thinner layer allows more ultraviolet rays from the sun to reach Earth. The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
Scientists first became concerned about the ozone layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter. The hole was caused by chemicals used in refrigerators and air conditioners. When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.
Concern about the protective ozone layer rose more recently when data from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica. Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.
Although many countries have already begun stopping the use of ozone destroying chemicals, the new findings are expected to advance the timetable for a total ban of the chemicals.
【1】What do we know about the hole in the ozone layer?
A．It was first discovered in the 19th century.
B．It only appears in winters of a year.
C．It can protect human from ultraviolet rays.
D．It was caused by particular chemicals.
【2】Which can best describe scientists' attitude to the condition of ozone layer?
A．Worried.
B．Scared.
C．Favorable.
D．Surprised.
【3】Why do people become more concerned about ozone layer?
A．Because the weather became worse and worse.
B．Because they knew ozone levels were dropping.
C．Because air pollution caused more cancer cases.
D．Because ozone destroying chemicals were banned.
【4】We can infer that ________.
A．people may not get skin cancer in winters
B．it is unnecessary to totally ban the chemicals
C．many countries have realized the damage of the chemicals
D．the situation become less serious in the past few years
27、2020 is special. When we dip into the model “suspended class, ongoing learning” during the pandemic(大流行）of NCP, have you thought of the inventors that supply us the convenience on the computers? Here, let’s know a respectable person who left us a few months ago.
Larry Tesler: computer scientist ,an icon of early computing, died at the age of 74 in this spring. Mr Tesler started working in Silicon Valley in the early 1960s, at a time when computers were inaccessible to the vast majority of people.It was thanks to his innovations ,which included the “cut”, “copy” and “paste” commands that the personal computer became simple to learn and use. Xerox, where Mr Tesler spent part of his career, paid tribute to him. “The inventor of cut/copy & paste, find & replace, and more, was former Xerox researcher Larry Tesler,” the company tweeted. “Your workday is easier thanks to his revolutionary ideas.”
Mr Tesler was born in the Bronx, New York, in 1945, and studied at Stanford University in California. After graduating, he specialised in user interface(界面) design, that is, making computer systems more user-friendly. He worked for a number of major tech firms during his long career. He started at Xerox Palo Alto Research Center (Parc), before Steve Jobs invited him for Apple, where he spent 17 years and rose to chief scientist. After leaving Apple he set up an education firm, and worked for brief periods at Amazon and Yahoo.
In 2012, he told the BBC of Silicon Valley: “There’s almost a custom -- after you’ve made some money, you don’t just retire, you spend your time funding other companies.”
“There’s a very strong element of excitement, of being able to share what you’ve learned with the next generation.” he added.
【1】Which of the following is true according to the second paragraph?
A．Mr Tesler innovated the computer.
B．Mr Tesler invented the “cut”, “copy” and “paste” commands.
C．Mr Tesler spent part of his career as a data man in Xerox company.
D．Most people have many chances to use computers in the early 1960s.
【2】How many companies did Larry Tesler once worked in ?
A．three
B．four
C．five
D．six
【3】Which word can best describe Mr Tesler as a scientist?
A．selfless
B．friendly
C．special
D．humorous
【4】What will the passage continue to talk about after the last paragraph?
A．Educating the next generation.
B．Discussing his retired life.
C．Showing the prospect of the Silicon Valley.
D．Sharing his knowledge with the next generation.
28、Students perform less well in final exams if smartphones are allowed in class, for non-academic (非学业的) purposes in lectures, a new study in Educational Psychology finds. Students who don’t use smartphones themselves but attend lectures where their use is acceptable also do worse, suggesting that smartphone use damages the group learning environment.
Researchers from Rutgers University in the US performed an in-class experiment to test whether dividing attention between smartphones and the lecturer during the class affected students’ performance in within-lecture tests and a final exam. 118 students at Rutgers University took part in the experiment during one term of their course. Smartphones were not allowed in half of the lectures and allowed in the other half. When smartphones were allowed, students were asked to record whether they had used them for non-academic purposes during the lecture.
The study found that having a smartphone didn’t lower students’ scores in comprehension tests within lectures, but it did lower scores in the final exam by at least 5%, or half a grade. This finding shows for the first time that the main effect of divided attention in the classroom is on the length of time in keeping memory, with fewer things of a study task later remembered. In addition, when the use of smartphones was allowed in class, performance was also poorer for students who did not use them as well as for those who did.
The study’s lead author, Professor Arnold Glass, added: “These findings should alarm students and teachers that dividing attention is having a not obvious but harmful effect that is damaging their exam performance and final grade. To help manage the use of smartphones in the classroom, teachers should explain to students the alarming effect—not only for themselves, but for the whole class.”
This is the first-ever study in an actual classroom showing a relationship between losing attention from smartphones and exam performance. However, more researches are required to see how students are affected by using smartphones after school.
【1】What is the purpose of paragraph 1?
A．To present the main findings of the experiment.
B．To explain how the experiment was carried out.
C．To give details about the result of the experiment.
D．To suggest what should be done for teachers and students.
【2】We know from the experiment that having a smartphone in class ________.
A．had no bad effect if students do not use them
B．caused an average 5% drop in students’ scores
C．made it harder for students to keep things in mind
D．had a bad effect on students’ performance in all tests
【3】What’s Professor Glass’ attitude towards using smartphones in class?
A．He was against it.
B．He was in favor of it.
C．He cared little about it.
D．He doubted the findings.
【4】What is the research team likely to do next?
A．To find out ways to improve students’ memory.
B．To call on schools to ban smartphones completely.
C．To study the influence of using smartphones after class.
D．To do researches on focusing attention in actual classrooms.
29、The heavy use of fossil fuels over the last 150 years has caused the Earth to warm up. That pattern will continue and get worse unless we stop the pollution very, very quickly. And even if we do end fossil fuel use, there’s still way too much of a polluting gas called “carbon dioxide”(CO2)in our atmosphere. Recent reports by scientists make it clear that this CO2 must be removed from the atmosphere and stored.
Plants and trees do this naturally. But there’s so much CO2 in the atmosphere that planting trees and protecting forests won’t come close to solving the problem. That means humans need to come up with ways of removing carbon from the air and storing it. This is called Direct Air Capture(DAC).
Last September, the world’s largest carbon capture factory opened in Iceland. Called Orca, the project is run by Climeworks, which works on capturing the CO2. Experts say that by 2030, we need to be able to remove 85 million metric tons of CO2 from the air. It would take 1, 000 factories like Orca over 20 years to remove that much. Factories that can remove even more CO2 are being planned, but it will take time for them to be built.
Until recently, scientists working on capturing carbon had a hard time finding support for their research. Now, because of the crisis, there are many scientists working on the problem, and many companies willing to pay for it. Governments worldwide have promised nearly $4 billion to develop carbon capture methods and factories.
Some people worry that there’s not enough time left for DAC technology to be developed and become powerful enough to make a big difference. Others worry that focusing on removing carbon could take attention away from more important climate actions, like switching from fossil fuels to renewable energy.
【1】What is Direct Air Capture(DAC)?
A．Recycling polluting gases in the air.
B．Removing and store carbon dioxide.
C．Storing carbon dioxide underground.
D．Getting rid of carbon dioxide directly.
【2】What does the writer intend to show in third paragraph?
A．1,000 factories will have been built by 2030.
B．Iceland will build more carbon capture plants.
C．There’s a very long way to go to achieve the goal.
D．Carbon capture factories have made huge progress.
【3】What can we infer from the text?
A．We will end fossil fuel use from now on.
B．Plants and trees can absorb CO2 naturally.
C．Governments have spent amounts of money on CO2.
D．Removing carbon dioxide from the air is challenging.
【4】What can we know from the last paragraph?
A．Not everyone is excited about carbon removal.
B．DAC technology should he developed quickly.
C．Renewable energy is enough for people to use.
D．More attention should be paid to climate actions.

The meaning of silence varies among cultural group. Silence may be 【1】, or they may be empty when a person has nothing to say. A silence in conversation may also show stubbornness, uneasiness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every 【2】 with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person’s needs. Many native Americans value silence and feel it is a basic part of 【3】 among people, just at some traditional Chinese and Thai persons do. Therefore when a person from one of these culture is speaking and suddenly stops, what may be 【4】 is that the person wants the listener to consider what has been said before continuing. In these culture, silence is a call for 【5】.
Other cultures may use silence in other ways, particularly when dealing with 【6】 among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show 【7】between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority（权威）rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.
Nurses and other care-givers need to be aware of the 【8】 meanings of silence wen they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own persona and cultural construction of silence so that a patient’s silence is not 【9】 too early or allowed to go on unnecessarily. A nurse who understands the healing 【10】 of silence can use this understanding to assist in the care of patients from their own and from other cultures.
32、阅读下面短文，根据其内容写一篇60词左右的内容概要。
While many of us go to sleep before midnight, some teenagers choose to stay up much later. They are not driven by the burning desire to write a better essay or achieve a higher grade. Instead, they are busy playing online games. Known as young Internet addicts (有瘾的人), they have long been a problem in China. A report released (发行) in 2016 by the China Youth Association for Network Development showed that there were over 24 million young Internet addicts among China’s young urban Internet users. The report also said that over 18 million youths had a tendency to develop Internet addiction.
To deal with the problem of Internet addiction among teenagers, the Cyberspace Administration of China has released draft (草案) regulations which carried out a ban on online gaming. If the regulations are adopted under-18s would be banned from playing online games between midnight and 8 am.
As soon as the government’s draft law surfaced, it drew great attention from the public. Some support the law as a way to better protect teenagers, saying that too much overnight gaming is harmful to teenagers’ health and believing the period between midnight and 8 am to be important to human physical functions. However, others wondered whether it would be practical if it came into effect, as teenagers could just borrow their parents’ IDs to register (注册) accounts to play online games. The Guangming Daily suggested that parents should help their teenagers find a balance between the cyber world and the real world.
China is by no means the only one trying to fight against teenager gaming addiction. Germany introduced a regulation in 2002 in an attempt to stop teens from playing online games from 10 pm to 6 am. Meanwhile, the UK, the US and Australia have forced a rating system on computer games to make sure that teenagers cannot access “adult” content such as violence, sex or bad language.
