高中英语人教版选修八Unit 2 Cloning同步练习 (3)

阅读理解

阅读下列短文,从每题所给的四个选项 (A 、B 、C  和 D )中,选出最佳选项。

    A recent announcement by scientists that they have successfully cloned the first human embryo(胚胎) has caused much debate and has shocked many people around the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable tissues(组织) and organs that could be used to save human lives. On the other hand, many people, including some scientists, disagree and fear that if mankind interferes with (干涉) nature in this way, they may be on their way to producing a real-life Frankenstein's monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly—the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were angry because they thought cloning would create more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific breakthrough.

    The Scottish scientist who created Dolly, Ian Wilmut, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, he has never thought of creating copies of humans. Instead, he thinks the scientists should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer. However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.

    While cloning human embryos is illegal in many countries, some scientists are already pushing ahead with the research so as to deliver a cloned human baby. Severino Antinori, an Italian doctor, is one of the leaders in this field of research. He has declared that he wants to be the first to clone a human being.

In China, scientists have focused their efforts on cloning animals, as well as stem cells to be used in medical research. China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.

(1)、Which of the following statements about cloning is TRUE according to the passage?
A、Cloning technology can only be applied to animals. B、A cloned animal can live longer than a normal one. C、People all over the world are happy about the birth of Dolly. D、Cloning can produce valuable tissues and organs to cure human diseases.
(2)、The reasons why some people disagree with cloning include the following EXCEPT that                .
A、cloning may produce a real-life Frankenstein's monster B、cloning might create more diseases in the animal world C、cloning human embryos shows no respect for human lives D、cloning can't help those who want to clone their dead children
(3)、Who is in favor of cloning human beings?
A、Ian Wilmut. B、Severino Antinori. C、The author. D、The Chinese scientists.

    A news release (释放,发布)is a tool of communication,through which information is passed to even the farthest end of the world.It keeps us well informed of the happenings of the world which would otherwise remain unknown.

    When writing a news release,keep in mind that the media receive hundreds of releases every day.Try to follow these guidelines:Keep it short and professional.Come up with a catchy headline that will grasp someone's attention.Sometimes the title will take more time to come up with than writing the release.That's okay-the headline could be critical for getting an event covered!

    Cover the 5 W's in your first paragraph.Those are who you are; what you are doing;where,when you are doing;why you are doing it,which help us understand the details about the event.Besides,any opinions in the news release should be put in quotations from your designated spokesperson.Include things that the media finds newsworthy,which is the most essential.

    Make the time on your news release at least half an hour later than the time you have told activists to show up at an event.This will ensure that activists are prepared and in place by the time the media arrive.

    Choose a spokesperson for the event who can be quoted in the release and will be available for calls at that number the day before the event.

    Have someone proof the release for spelling,grammar and content (determine whether what you are trying to relay is clear and right).Sometimes the person who writes the release may not notice mistakes that a fresh pair of eyes will catch.

    Accuracy is the last but not least important in terms of your content and the location and time that you tell the media.If you do make a mistake,it is critical that you call and notify the media of the correction.

    To eat only a vegan(素食的) diet might sound difficult, especially with many popular dishes containing meat or other animal products. Yet in 2017, veganism was described as “the fastest - growing lifestyle movement” in the UK, according to BBC news.

    A study by a UK market research organization, suggests that over 542,000 Brits went vegan during the previous decade, an increase of 360%. And the main force behind this increase was those aged 15-34 years old — 42% of recent vegans fall under that age range.

    So why exactly has veganism become so popular among young Brits?

    One reason could be that many young people want to protect the environment, as less meat consumption is known to be beneficial to the environment. Global meat manufacturing is believed to cause 18% of the world's greenhouse gas emissions(排放), even more than that of all the world's cars, trains and planes combined. Another reason is that many of today's young people believe that it's wrong to kill animals to be used as food.

    Jess Murray, 22, a student at University College London, said that he chose to become vegan after realizing that eating animals is a choice that people make, rather than something that we need to do to survive. “Becoming vegan was an ethical (道德的) decision,” he told the Guardian.

    Social media is also believed to have given rise to the increase in veganism. Platforms such as Facebook allow young vegans to connect with each other much easier, while others such as Instagram have led to the creation of “vegan celebrities (名人)”, who share lips on vegan lifestyles.

    Despite the rising of veganism, Laura Wyness, an expert in diet and nutrition, said that meat is very important for people's health. “A strict vegan diet makes it difficult to get some minerals and vitamins that your body needs,” Wyness told BBC news.

    However, the popularity of veganism doesn't seem to be fading. “It feels more like this is something that is sticking.” said an expert of the Vegan Society, a UK charity that promotes veganism.

    School uniforms are becoming more and more popular across the USA. That's no surprise, because they offer many benefits. If all students are dressed in the same way, they will not pay too much attention to their clothing, and some of them will not be laughed at for wearing the "wrong" clothes.

Some people are against the strict rule of school uniforms, but they do not realize that students already accept a kind of rule —- wanting to look just like their friends. The difference is that the clothing students choose for themselves creates social barriers(阻碍); school uniforms tear those barriers down.

    Some parents are unhappy about uniforms, saying that school uniforms will affect their children's "creativity". First, as noted above , the clothes students choose to wear do not necessarily express their individuality(个性). They just copy their classmates. Second, students have the rest of the day to be as creative as they like. While they're in school, their job is to master reading, writing, and math; this should take up all the creativity they have. Mastery of those skills will be good for the students to build up their creativity in every way.

    As in other places, uniforms remind the wearers of their purpose and duties. For example, when a man or woman puts on a police uniform, he or she becomes, for a time, the symbol(象征) of law and order. The uniform means to the wearer his or her special duties and sends the same message to everyone the wearers meets. People with different jobs wear uniforms of one kind or another. For students, the school uniform reminds them that their task for the six or seven hours they are in school is to get an education.

Five trends to watch in the coming year

The number 21 is connected with luck, risk, taking chances and rolling the dice, all of which seem strangely appropriate for a year of unusual uncertainty. As 2021 approaches, here are some trends to watch in the year ahead.

⒈ Fights over vaccines

As the first vaccines become available in quantity, the focus will shit from the heroic effort of developing them to the equally difficult task of distributing them. Vaccine negotiations will accompany fights within and between countries over who should get them and when.

⒉ A mixed economic recovery

As economies bounce back from the pandemic, the recovery will be inconsistent, as local outbreaks and restrictions come and go — and governments turn from keeping companies on life-support to helping workers who have lost their jobs.

⒊ A less footloose world

Tourism will shrink and change shape, with more emphasis on domestic travel. Airlines, hotel chains and aircraft producers will struggle, as will universities that rely heavily on foreign students.

⒋ An opportunity on climate change

One positive side to the crisis is the chance to take action on climate change, as governments invest in green recovery plans to create jobs and cut emissions. How ambitious will countries' reduction promises be at the UN climate conference, delayed from 2020?

⒌ The year of déjà vu

That is just one example of how the coming year may feel, in many respects, like a second take on 2020, as events including the Olympics, the Dubai Expo and many other political, sporting and commercial gatherings do their best to open a year later than planned.
