Since September about 11m hectares of Australia have been in flames. This year’s fires are the worst on record, with at least 26 people dead, about half-billion animals burned alive, and over 2300 homes destroyed. Australians of all species are suffering the most. But the fires have serious consequences for the rest of the world, too.
New Zealand, one of Australia’s closest neighbors, is feeling the effects of the bushfires. The most important effect of the fires might be on the country’s glaciers, about which Helen Clark, New Zealand’s former prime minister, tweeted: “Australian bushfires have created haze in New Zealand with particular impact on the South Island yesterday and now spreading more widely. Impact of ash on glaciers is likely to speed melting.” Melting glaciers could open up a future none of us wants to suffer.
There’s no such thing as weather that happens in isolation. As a recent Forbes article reports, fires have the potential to not only block visibility for airplanes, grounding them, but to create pockets of hotter or colder air, or create situations where the weather is increasingly less stable — although no one is yet certain how far from the Australian continent those effects might wander, or how harmful they may prove to be.
In addition to coal, Australia also exports all kinds of agricultural products — like beef and wool—particularly to Asian countries including China and Japan. But what happens when the land it uses to grow all that food and fiber is destroyed by fire? Obviously, no more goods to export, which creates a huge problem in the international supply chain. Thanks to globalization, pretty much no country eats only the food it grows. What happens to the global food supply as agricultural land in Australia and other export nation’s burns to a crisp?
1.What can we learn about the Australian bushfires?
A.They’ve left most of Australian land in flames.
B.They’ve speeded the melting of glaciers.
C.They will certainly create hotter air.
D.No one is certain how harmful their effects will be on climate.
2.What’s the author’s attitude towards the future of the global food supply?
A.Doubtful. B.Objective.
C.Concerned. D.Indifferent.
3.What is the best title for the text?
A.The Effects of the Australian Bushfires on Climate Change
B.Australian Bushfires: a Big Disaster to the Country
C.What the Australian Bushfires Mean for the Rest of the World?
D.Why the Australian Bushfires Affect the Rest of the World?

Since December,there have been tens of thousands of the COVID-19 cases both in and out of China,caused by a previously unknown virus:novel coronavirus.
What are they?Viruses are considered to be non-living organisms(有机物).They can't reproduce(繁殖) on their own. Instead, they invaded the cells of living organisms to reproduce, spread and take over.But the basic question is,where did viruses first come from? Until now, no clear explanation for their origin exists.
Understanding the origins of viruses means fully understanding the history of their hosts not only humans,but also bacteria,plants and other animals,which is a complicated task. However,there are three main theories to explain the origin of viruses.First,viruses started as independent organisms,then became parasites(寄生者). Second,viruses evolved(进化) from pieces of DNA or RNA that"escaped"from larger organisms.The third one is that viruses co-evolved with their host cells,which means they existed alongside these cells.
For the time being,these are only theories.The technology and proofs we have today cannot be used to test these theories and discover the most plausible explanation.Continuing studies may provide us with clearer answers.Or future studies may find that the answer is even more mysterious than it now appears.
1.What can we learn about viruses from the article?
A.They mainly infect animals and plants.
B.They are really small living organisms.
C.They are more dangerous than bacteria.
D.They can't reproduce unless they find a host cell.
2.Which of the following might explain the origin of viruses?
A.They evolved along with their host cells.
B.They evolved from the DNA or RNA in animals.
C.They evolved from the fossils of large organisms.
D.They evolved from parasites to independent organisms.
3.The underlined word"plausible"in the last paragraph probably means______.
A.creative B.reasonable
C.common D.unbelievable
4.What can we conclude from the article?
A.The author is confident about future virus research.
B.Viruses will become more like bacteria as they evolve.
C.Viruses live longer in human host cells than in animals.
D.It may take a long time to understand the origin of viruses.

Animals have been used, and sometimes abused(虐待), in movie-making since the early days of the industry. However, the American Humane Association has worked for many years to protect animals in films. And, the digital age might make animal actors unnecessary.
The new film “Dolphin Tale” tells about a dolphin that loses her tail because of an injury from a crab-trap. A doctor provides her with an artificial tail that saves her life. The film is based on a real event. And the star of the film, Winter, is a real dolphin that lost her tail. The American Humane Society worked with the movie’s makers to make sure Winter stayed safe and healthy during filming. The animal protection group does this for all animal actors in America.
A thick book of rules and guidelines tells Hollywood moviemakers how to treat animals. Karen Rosa leads the American Humane Society’s film and television group. He said, “Everything from the smallest insect to the largest mammal shall be protected. We believe that for the sake of entertainment, everybody should go home alive.
This was not always the policy in the early days of film. In 1939, a horse was forced off a mountain, falling to his death, in the movie “Jesse James.” The next year, guidelines were established to guarantee safe and healthy conditions for animals in movies.
A new film “Rise of the Planet of the Apes” tells about the creation of super intelligent apes through science. However, no real animals were among the performers. Computer generated imagery provided the chimpanzees, gorillas and orangutans that movie goers see. Clare Richardson is the president of the Diane Fossey Gorilla Fund. She says computer generated imagery should decrease the use of animals in the film industry. She praises movie makers for the use of computer-made animals.
1.What’s mainly talked about in the text?
A. How to protect animals in making films.
B. How to create animal actors by computer.
C. How to use animals to produce digital films.
D. How to improve the movie-making industry.
2.When was it forbidden to abuse animals while making films?
A. In 1939. B. In 1938.
C. In 1941. D. In 1940.
3.The film Rise of the Planet of the Apes mainly tells about ____________.
A. how directors protect actors in making movies
B. how people make use of real animals in films
C. how the computer-made animals replace humans
D. how intelligent animals are created through science
4.Which of the following is TRUE of Clare Richardson?
A. She believes that computer-made animals are dull.
B. She thinks highly of the computer-made animals.
C. She is famous for making films with animal actors.
D. She directed the film “Rise of the Planet of the Apes”.

Since people first sent rockets into space in the 1950s, we have been leaving behind all sorts of things. Some of them, like the camera, were lost by astronauts while they did work outside their spaceship. But much of the space junk is made up of little pieces of things that were once bigger objects, until they struck each other and broke apart.
Some things we send into space fall back toward the earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit the ground or the ocean at great speeds. So there is always concern that something may fall from the sky and do some harm.
But space junk falling on housetops (屋顶) is not the biggest worry. Scientists are concerned about what happens when an empty rocket strikes another while orbiting (绕轨道飞行) the earth. Two big things become many smaller things. They then hit other things. The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles.
So what can be done to clean up the space around our planet? Marco Castronuovo, an Italian researcher, talks about sending a satellite into space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the earth. After a time, the junk burns up in the atmosphere.
Mr. Castronuovo has proposed (提议) using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite would jump from one large piece of junk to another. He thinks this method could destroy about ten large objects each year.
Scientists have been concerned about space junk for many years. Right now, the costs of the clean-up have been too great. Mr. Castronuovo says his system could be put in place for a much more reasonable amount of money.
1.Much of the space junk _____.
A．was thrown by the astronauts
B．is from broken spaceship
C．is made up of small pieces of things
D．returns to the earth piece by piece
2.Scientists are most worried that the space junk _____.
A．will stop the future space vehicles
B．will do harm to the atmosphere
C．will fall on the housetops
D．will burn up in space
3.What does Marco Castronuovo think of his system?
A．It can remove space junk completely.
B．It can save a large amount of money.
C．It can create a large amount of space.
D．It can develop robotic technology.

I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me to the World Wide Web.
I’ve always felt like a master of the Internet world. MSN, Gmail, Facebook, My space -- I’ve got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.
Some online businesses are run from one-room home offices. Others have hundreds of employees across the world. Have you ever heard of Amazon.com, Yahoo.com?
My friends often said they got cheap textbooks on Amazon.com, or had a good deal (交易) on Steve Madden shoes that were on sale at SteveMaden.com. Unfortunately for me, I continued my “e-commerceless” Web-surfing, not knowing about all the deals I was missing out on.
That is, of course, until my sister finally sold the idea to me.
“Why are all these packages arriving in the mail for you, Katy?”I asked her one day. Strange envelopes (信封) had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know little sisters should never be getting more mail than their elders!
“Oh, it’s the things I ordered online!” she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!
“How much did all of this cost?”
“Oh, only about $15 in all!”She said excitedly.“Everything on eBay is on sale! It’s a way better than going to the store.”
I felt as if there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.
1.From the first two paragraphs we can conclude that the writer___________.
A. had no experience using computers
B. had no idea of what e-commerce is
C. only enjoyed checking e-mail on the Internet
D. thought surfing the Internet was a waste of time

A. he stopped web-surfing
B. he visited a store in his backyard
C. his sister explained the packages she got by mail
D. his friends told him about the online deals they made
3.We can infer from the last paragraph that the writer____________________.
A. never enjoyed shopping that much
B. loves the big store in his backyard
C. feels he is a true master of the Internet
D. has begun to enjoy online shopping
4.What’s the purpose of the article?
