In an ideal world, people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals, and expensive and time–consuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year.
Europe, on the whole, has the world’s most restrictive laws on animal experiments. Even so, its scientists use some 12 million animals a year, most of them mice and rats, for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and, as these are the most common laboratory animals, the true figure is much higher. Japan and China have even less comprehensive data than America.
Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing, such as using human tissue or computer models, are now strongly recommended. In addition, sharing all research results freely should help to reduce the number of animals for scientific use. At present, scientists often share only the results of successful experiments. If their findings do not fit the hypothesis being tested, the work never sees the light of day. This practice means wasting time, money, and animals’ lives in endlessly repeating the failed experiments.
Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue, even if that means animals sometimes suffer. Europe’s new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.
1.What is the main idea of this passage?
A. The success of animal experiments should be ensured.
B. A ban on the use of animals in the lab should be enforced.
C. Greater efforts need to be taken to reduce the number of lab animals.
D. Scientists should be required to share their research results with each other.
2.Which of the following statements is true about animals used in the lab?
A. America uses only about 1.1 million lab animals per year.
B. Europe does not use mice and rats as lab animals at all.
C. Britain does not use as many lab animals as China does.
D. Japan has less comprehensive data on the number of lab animals used each year.
3.Which of the following is mentioned as an alternative to replace animal experiments?
A. Statistical studies.

C. DNA planted in animals.
D. Tissue from dead animals.
4.What usually happens to unsuccessful animal experiments?

In an ideal world, we might be able to live free from discrimination. But not this one, in which we are constantly dividing everything into “us" and “them".
This is especially true during times of fear, like now, when the novel coronavirus is spreading across China and the world. It's a time when “us" means safe and clean while “them" means infectious and risky. Or at least we'd like to believe so.
But this is actually a misbelief, which has been fueled and promoted by fear, and sadly, the media. When the outbreak first started, the term “Wuhan virus" was used in some news, creating hostility (敌意)toward people from Wuhan and Hubei as a whole. There were reports of hotels refusing to accept guests from Hubei and some hospitals denied their entry even when they needed treatment for other medical problems.
Elsewhere in the world, German magazine Der Spiegel labeled the virus on its cover as “Made in China". Australia's Herald Sun, meanwhile, printed, “China Kids Stay Home" on its front page, implying that all kids from China are carriers of the virus. It's also reported that Chinese people overseas have faced harassment (骚扰)and even violence.
This kind of misbelief is exactly why and when the World Health Organization (WHO) was trying to come up with a name for the disease, it had to be careful. “We had to find a name that did not refer to a geographical (地理的)location, an animal, an individual or group of people," said Tedros Adhanom Ghebreyesus, Director-General of the WHO, on Feb 11. And COVID-19 was the final decision.
World leaders and institutes are also sharing sensible voices. "There is no place in our country for discrimination driven by fear or misinformation," Canadian Prime Minister Justin Trudeau said at a Lunar New Year celebration in Toronto on Feb 2. Cornell University also sent an email to students and faculty, saying, “We need to remember to care for one another and not make assumptions about others' symptoms or any characteristics of identity."
It's understandable that during times like this, we want to go to extreme lengths to make sure we're safe. But fear is never part of the cure. Only love and independent thinking takes you further.
1.What is the main purpose of Paragraphs 3 and 4?
A.To explain what has brought about misbelief.
B.To show how some news media misled the public.
C.To compare how different countries responded to COVID --- 19.
D.To present what Chinese people overseas suffer from COVID --- 19.
2.Justin Trudeau and Cornell University are quoted in the text to .
A.show positive attitudes in face of COVID ---19
B.explain why it is important to prevent discrimination
C.describe different opinions of the influence of the virus
D.introduce measures taken by foreign countries to fight COVID---19
3.What's the attitude of the author towards "discrimination"?
A.Neutral. B.Supportive. C.Opposed. D.Unconcerned.
4.What is the main idea of the passage?
A.We should always be willing to care for others.
B.Fear and discrimination are as contagious as a virus.
C.We shouldn't let misinformation influence our own judgment.
D.The media should give people confidence during times of fear.

高三英语单项填空简单题查看答案及解析
In an ideal world, we usually get eight hours of sleep every night, and wake up with enough energy before work. But when we're struggling to balance the responsibilities of everyday life, cutting back on sleep seems to be the only solution. Many of us rely on coffee or energy drinks to get us through the day, instead of making sleep a priority. Sadly, as delicious as it can be, caffeine is not the solution. Being tired not only brings down our energy levels, but also makes us less productive and less motivated. There are concrete steps you can take right now to renew your energy.
Awareness comes first because you have to understand what's going on before you can do anything to change it. Most of us are too busy to notice how fatigue(疲劳) really affects our bodies and minds. What signs of trouble do you regularly display? The patterns of your signs of trouble can give you clues about the negative effects of your fatigue. In addition, it's wise to start thinking about whoever can feel the effects of your fatigue.
Reflecting on the choices you've made can provide clarity, which will help you figure out what needs to be changed. During this reflection, you will be able to understand more about yourself and why you do the things you do. You may decide to forgive yourself for the mistakes you've made. Thinking about the positive aspects of your life will make you feel refreshed and ready to move forward.
Conversing with others not only provides support, but also leads to new perspectives and feedback that can help with treatment and what you need to heal. To start with, have an open mind and an open heart. Limit complaining. Complaints may need to be aired in order to relieve pressure, but if they dominate(占上风), anger will win. Tell the truth. You do not need to tell people everything, but you do need to be honest. Listen carefully because it shows respect.
The fourth step is about renewal—getting rid of what is bringing you down and making a fresh start. It's helpful to break the process down. It is easier to make small adjustments than big ones. On occasion, the small steps alone can remove fatigue. For instance, you may not need to change your career but change emphasis. If you feel hopelessly dragged down by fatigue, selfcare may be the best prescription.

The world is not coming to an end on December 21, 2012, the US space agency insisted Monday in a rare campaign to dispel widespread rumors fueled by the Internet and a new Hollywood movie.
The latest big screen offering from Sony Picture, 2012, arrives in theaters on Friday, with a 200-million-dollar production about the end of the world supposedly based on myths backed by the Mayan calendar.It is claimed that the end of time will come as a Planet X---or Nibiru---heads toward or collides with the Earth.
Some websites accuse NASA of hiding the truth on the planet’s existence, but the US space agency condemned such stories as an “Internet hoax”.“There is no factual basis for these claims,” NASA said in a question-and-anwser posting on this website.“If such a collision were real, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye.Obviously, it does not exist.Credible scientists worldwide know of no threat associated with 2012,” it insisted.“After all, our planet has been getting along just well for more than four billion years,” added NASA.
There is another planet, Eris, floating in space.But the small planet similar to Pluto will remain safely fixed in the outer solar system and it can come no closer than four billion miles to the Earth, according to NASA.
Earlier theories set the disaster for May 2003, but when nothing happened the date was moved forward to the winter in 2012 to coincide with the end of a cycle of the ancient Mayan calendar.
NASA insisted the Mayan calendar in fact does not end on December 21, 2012, as another period begins immediately afterward.
And even if the planets were to line up as some have forecast, the effect on our planet would be “negligible(unimportant)”, NASA said.
“And while comets and asteroids (小行星) have always hit the Earth, big hits are very rare,” NASA noted.The last major impact was believed to be 65 million years ago, resulting in the end of dinosaurs.
“We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs,” the space agency said.
1.______ played a key role in the spread of the rumors.
A.A new book B.The Internet and a new Hollywood movie
C.NASA D.An Indian calendar
2.We can infer that ______.
A.people didn’t take the rumor seriously
B.Planet X --- or Nibiru does exist
C.astronomers have been tracking Planet X for over ten years
D.the rumor caused a panic among some people
3.NASA thinks that Eris ______.
A.might have a threat to the Earth B.doesn’t have any threat to the Earth
C.is too far away to be visible D.is similar to our planet, where life might exist
4.Which of the following is the best title?
A.New Hollywood movie 2012
B.December 21, 2012, Not the end of the world
C.End of the ancient Mayan calendar
D.How rumors came into being
