21、 If Mars were the popular kid in school, Venus (金星)would be the unwelcome one sitting in the corner, largely ignored. Venus has nearly the same mass and size as Earth, but being closer to the sun, it gets nearly twice as much heat from the sun.
However, instead of having a climate that is just a warmer version of Earth’s, Venus's surface and atmosphere are unbearable: clouds of sulphuric acid blanket the planet, while at ground level, it is hot enough to melt lead. Despite this, there is now a sign that Venus may harbour life.
Jane Greaves at Cardiff University, UK, and her colleagues recently detected phosphine (磷化氢)in Venus's atmosphere, with one potential explanation that it is the by-product of biology. That is because the only way this gas is made on Earth is in laboratories or by microbes(微生物).Though this doesn't mean it was produced by life on Venus, attempts to find non — biological explanations for its presence have so far failed.
Our best way of confirming or rejecting the possibility of life on Venus is to go and have a proper look. While Mars has been the focus of interplanetary exploration efforts lately, the phosphine discovery lets people look at Venus in a new light. As NASA administrator Jim Bridenstine tweeted： "It's time to prioritize Venus.”
In the months and years to come, computer simulations will be used to further study the possible chemistries of the atmosphere on Venus. More laboratory experiments will be conducted to try to identify other ways the phosphine there could be produced. However, there is no guarantee that these efforts will reveal the true nature of this substance on Venus. A newly-proposed strategy is to directly sample the atmosphere and surface of Venus. By doing so, we would be able to take direct measurements of phosphine.
The discovery of phosphine in Venus's atmosphere is a great accomplishment. The scientific efforts may be just what we need to finally refocus on this neglected world. Possibly, the quiet kid in the corner may get the last laugh.
【1】In theory, what's Venus expected to be like?
A.It is almost as large as Earth.
B.It has nearly the same mass as Earth.
C.It has a warmer Earth-like climate.
D.It has the unbearable surface and atmosphere.
【2】What can the discovery of phosphine on Venus indicate?
A.There might exist signs of life.
B.This kind of gas is very common.
C.Many products can be made with it.
D.Experiments were once conducted there.
【3】What is paragraph 5 mainly about?
A.The importance of observations.
B.The power of computer simulations.
C.The approaches to exploring phosphine.
D.The necessity to analyse phosphine.
【4】Which can best describe the author's attitude to the exploration of Venus?
A.Casual. B.Supportive. C.Cautious. D.Doubtful.
22、Throughout history, music spread through common experiences among people of different cultures. In today’s technologically advanced society, however, people spread music online, sometimes without an artist’s permission. This can lead to many problems, and music companies are now cracking down on this practice. Sharing music online without permission is theft.
Sharing music online prevents recording companies from making money from their efforts. They say that online file sharing has resulted in a huge drop in profits and sales over the past 10 years. People who find music for free online are not charged for CDs or every MP3 download. To truly understand the impact of music piracy on creators, one must understand how many people are involved in the recording process. For the sale of each album, profits must be shared between all parties: musicians, sound engineers, music producers, managers, advertisers, and the company selling the product. Many people believe sharing music only affects the recording artist, but the reality is that sharing hurts business for all companies involved. Therefore, the sharing of music files is just as damaging as stealing a CD from Target.
There are many people who don’t see the harm in sharing music files online and even think they have the right to do it. One online blogger states that he originally paid for an entire CD and that he “should be able to do with the material whatever he wants”. While he may have legally paid for the music, he does not have the right to provide it to the world at no cost. Most music is copyrighted. No one can legally hand out free copies without permission, which means people like the blogger are thieves.
Although we do not spread today’s music the same way we did historically, there’s no doubt that people around the world love to share music. However, Internet piracy could prevent musicians from wanting to continue producing albums for fear of theft. Therefore, if people want to continue listening to their favorite artists, they need to buy their music so that artists will make enough profit to continue their music careers.

C．Dealing seriously with.
D．Destroying completely.
【3】We can learn from the text that .
A．artists are taking action to protect their rights
B．sharing music files online affects a lot of people.
C．online music sharing increases sales of music CDs.
D．a person who has bought a CD has the right to share it online.

There are so many to choose from! I love Robert Frost, especially “Mending Wall”, mostly because he is my dad’s favorite poet. However, personally I love Lnagston Hughes’s poem “Dreams” because it always brings happiness to me. I am also a big fan of the older poems, such as Spenser’s “One Day I Wrote Her Name Upon the Strand” because it is so simple, and “The Tyger” and “The Lamb” by William Blake because I love the language.
Michael Ugulini 51 minutes ago
My favorite poet is Suji Kwock Kim. Ever since I read her book of poetry “Notes from the Divided Country”, I have been a big fan of her clear and thoughtful writing. My favorite poem of hers is “Borderlands”, which she wrote in memory of her grandmother. It is a poem about her grandmother’s experiences during the war.

26、Directions: Read the following three passages. Summarize the main idea and the main point（s）of the passage in no more than 60 words. Use your own words as far as possible.
How Come Scientists Draw Opposite Conclusions?
One of the biggest concerns is science is bias-that scientist themselves, consciously or unconsciously, may put their thumbs on the scales and influence the outcomes of experiments. But gathering the data and running an experiment is not the only part of the process that can go awry. The methods chosen to analyse the data can also influence results even if being based on the same data-set.
A new paper, headed by Martin Schweinsberg, a psychologist at the European School of Management and Technology, in Berlin, helps shed some light on why. Dr Schweinsberg gathered 49 different researchers with each handed a copy of a data-set consisting of nearly 8,000 comments made on an online forum for chatty intellectuals. Dr Schweinsberg asked his guinea pigs to explore a seemingly straightforward hypothesis(假设)that a woman’s tendency to participate would rise as the number of other women in a conversation increased. Crucially, the researchers were asked to describe their analysis in detail by posting their methods and workflows, which allowed Dr Schweinsberg to see exactly what they were up to.
As it turned out, no two analysts employed exactly the same methods, and none got the same results. Some 29% of analysts reported that women do indeed participate more, if plenty of other women are present. But 21% concluded that the opposite was true. (The remainder found no significant difference).
The problem was not that any of the analyses were “wrong” in any objective sense. The differences arose because researchers chose different definitions of what they were studying, and applied different techniques. When it came to defining how much women spoke, some analysts plumped for the number of words in each woman’s comment. Others chose the number of characters. Still others defined it by the number of conversations that a woman participated in, irrespective of how much she actually said. The statistical techniques chosen also had an impact, though less than the choice of definitions. Some researchers chose linear-regression analysis: others went for logistic regression or a Kendall correlation.
Truth, in other words, can be a slippery customer, even for simple-sounding questions. What to do? One conclusion is that experimental design is critically important. It is recommended that scientists specify exactly how they chose to perform their analysis, allowing those decisions to be reviewed by others. It is probably not practical, he concedes, to check and re-check every result. But if many different analytical approaches point in the same direction, then scientists can be confident that their conclusion is the right one.
