As scientific meetings are canceled worldwide, researchers are rethinking how they network a move that should have done earlier. “At some point, we need to be having conversations about ‘What is the point of a conference now? says Sarah Horst, a planetary scientist.
Meeting spaces that are inaccessible to some disabled scientists, health considerations, a lack of access to childcare and travel restrictions can all encl up alienating potential attendees from physical conferences. There’s a large appetite” for alternative conference set-ups, says Divya Persaud, a planetary scientist. She and Eleanor Armstrong, a UCL sociologist of space science, have a grant from their university to hold an experimental virtual conference, called Space Science in Context, in May. The conference aims to improve accessibility. Participants will watch recorded talks ahead of time and then join in online conversations on the day of the conference. Persaud says that the response to plans for the meeting, which launched its save-the-date website last week, has been overwhelmingly positive. But she also points out that many of the adjustments that conferences are making, such as introducing virtual participation, are accommodations for which disabled scientists have been demanding loudly for years, and it’s a shame that it took a global health crisis to make them happen.
Still, as conference organizers are finding out, making these changes, especially on short notice, is no easy thing. The European Geophysical Union (EGU) general conference is scheduled for 3---8 May in Vienna, and session leaders are making other plans in case it is canceled. Those intending to participate in the Lunar and Planetary Science Conference this week in The Woodlands, Texas, found that they are trying to come up with alternative solutions when that conference was canceled on 4 March. Most of the responses were just ‘ Well , have the conference online’ “ says Horst.
1.Which of the following is NOT a potential attendee?
A.Scientists without visas. B.Scientists who are not feeling well.
C.Scientists with physical disabilities. D.Scientists who don't understand childcare.
2.What is the public’s attitude towards online conference?
A.Uncertain. B.Supportive. C.Disappointed. D.Dissatisfied.
3.Why does the second paragraph take Space Science in Context as an example?
A.To show that modern technology can realize conference online.
B.To prove that virtual conferences can make more people involved.
C.To praise the conference organizing ability of these two scientists.
D.To emphasize that the previous physical meetings were unsuccessful.
4.Where would this passage most probably appear?

Scientific research depends on far-sighted people who can think outside the box. Such research is key to our understanding of the universe, the development of physical science, and our ability to enjoy world-changing technology products.
One such far-sighted people is John B. Goodenough, now 97, who developed the lithium-ion battery (锂离子电池) in the 1970s. Now, decades after his important breakthrough, Goodenough enters history as the winner of the Nobel Prize in chemistry of 2019. He shares the award with Akira Yoshino, 71, and M Stanley Whittingham, 77, who co-created the battery with Goodenough at the University of Oxford.
“Through their work, they have created the right conditions for wireless and fossil fuel-free society, and brought the greatest benefit to humankind,” said the Nobel Foundation.
Yet despite this rechargeable battery benefiting billions of people around the world every day, we too often take science for granted.
Indeed, the Nobel Committee - and even Goodenough himself - hadn’t seemed to appreciate the impact his research would have on future generation. “At the time we developed the battery, it was just something to do,” Goodenough told the Times Newspaper earlier this year. “I didn’t know what electrical engineers would do with the battery. I really didn’t anticipate cellphones, camera and everything else.”
As many have agreed - and Goodenough shows - the science of today is the technology of tomorrow. Goodenough’s invention is evidence of imagination being put to work for the greater good. For that, his research is good enough at last.
1.Why does Goodenough enter history?
A.Because he is the oldest man in the world.
B.Because he is a famous scientist.
C.Because he has won the Nobel Prize in chemistry.
D.Because he worked with other scientists.
2.The underlined word “anticipate” in Paragraph 5 is closest in meaning to _________.
A.show B.instruct C.expect D.invent
3.What can we learn from the text?
A.Goodenough’s invention has benefited human beings a lot.
B.Most people don’t take science for granted.
C.Goodenough discovered the lithium-ion battery in the1970s.
D.The Nobel Prize in chemistry in 2019 is awarded to Goodenough alone.
4.What would this passage most probably be?
A.story. B.An advertisement. C.A biography. D.A news report.

Women, as all research suggests, are far more critical of their appearance than men. Most of them are likely to feel dissatisfied with their reflection in the mirror.
It is quite possible that men looking in the mirror are either pleased with what they see or indifferent. Research shows that men generally have a much more positive body-image than women---if anything, they may tend to over-estimate their attractiveness. Some men looking in the mirror may literally not see the flaws in their appearance.
Why are women so much more self-critical than men? Because women are judged more on their appearance than men, and standards of female beauty are considerably higher and more inflexible. Women are continually bombarded (轰炸) with images of the “ideal” face. And constant exposure to idealized images of female beauty on TV, magazines and billboards makes exceptional good looks seem normal and anything short of perfection seem abnormal and ugly. It has been estimated that young women now see more images of outstandingly beautiful women in one day than our mothers saw throughout their entire adolescence.
Also, most women trying to achieve the impossible standards of female beauty have in fact become progressively more unrealistic during the last century. In 1917, the physically perfect woman was about 5 feet 4 inches tall and weighed nearly 10 stone. Even 25 years ago, top models and beauty queens weighed only 8% less than the average women, now they weigh 23% less. The current media ideal for women is achievable by less than 5% of the female population---and that’s just in terms of weight and size. If you want the ideal shape, face etc., it’s probably more like 1%.
1.The passage is mainly to _____________.
A．compare different views on beauty between women and men
B．tell us that standards of female beauty are very high
C．explain why women are more critical of their appearance than men
D．show us that women pay more attention to their appearance than men
2.Which of the following is NOT the reason why women are more critical of their appearance?
A．People pay more attention to their appearance than men’s.
B．The criterion (标准；准则) used to judge women’s beauty is more critical and less changeable.
C．Idealized images of female beauty are constantly shown in different media.
D．Women tend to pursue perfection by nature.
3.Which statement is true about men?
A．Few men will feel pleased when they are looking themselves in the mirror.
B．Men looking in the mirror usually ignore the flaws in their appearance.
C．It is likely that men will consider themselves more attractive than they really are.
D．Men don’t care about their body image.
4.Nowadays, if an average woman weighs 110 pounds, then a physically perfect woman should weigh about _________.
A．85 pounds B．101 pounds C．90 pounds D．135 pounds
5.What can be inferred from the last paragraph?
A．Most women try to achieve the standards of beauty.
B．The standards of female beauty. in the past were more easily achieved than today.
C．Women are more unrealistic in their pursuit of beauty than men.
D．Less than 5% of the female population can achieve the current media ideal for women.

Recently there was a major discovery in the scientific research — the mapping of all DNA in a human gene(基因) is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument, in terms of morality(道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations, then the other clone would be as well. The latter could be inserted in the woman and allowed to ripen to term. Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle” of life. There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal. Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades” of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.
1. Which of the following is true according to the passage？
A. Genetic limitation will be beneficial for some women
B. A large number of genes will prevent us from developing
C. Prohibition(禁止) of cloning might limit the freedom of scientists
D. First cloned humans might be normal according to scientists
2.What’s the author’s opinion on cloning?
A. Cloning should be entirely banned
B. Cloning should be used in creating life
C. Cloning will take away the right to reproduce
D. Cloning is acceptable if it is used for cloning organs
3.Which of the following shows the structure of the passage
