A
There are three reasons why I don't think that we are ready for cloning. Firstly, we don't know exactly what the consequences of cloning would be. For example, if scientists cloned a man, they might know what he would look like, but they wouldn't know his quality. What would happen if scientists cloned another Hitler or others like him? Do you really think we would survive if this became a reality?
Secondly, cloning raises many ethical questions. Look back at the cloned man that has been presented and ask yourself these questions：
“Do you really think that he would be a man？” “Who would be responsible for him？”
“Do you think he should have the same rights as we have？” I don't think that we can answer these questions now.
Lastly, we don't know exactly what the meaning of life is. In my opinion, creating life is the duty of nature, and we must not interfere (干预) with that task because we can't understand the extremely complicated relationships among lives that are defined by nature. Usually these relationships are extremely complex. Sometimes, they seem to be so untouchable that they cannot be changed. From my point of view, we have to look at the natural environment around us. We can see that an ecosystem (生态系统) is made up of a lot of different kinds of life, and each life has its own function within the system. If we disturb that, I think it could lead to our extinction (灭绝)．
Even though cloning may have a lot of benefits for humans, I think we should stop cloning because we do not understand it and can't control all of its effects. Maybe in the future, we will be ready to do it, but that time has not yet arrived.
语篇解读：本文主要从三个方面讲述了我们为什么不要克隆。
1．According to the author, we are not ready for cloning because ________. A．two or more people may have the same appearance
B．scientists are not sure about the personalities of the cloned people
C．people may not function properly if there are more cloned human beings D．cloning has not been permitted by the government
解析：选B 细节理解题。从第一段“For example, if scientists cloned a man, they might know what he would look like, but they wouldn't know his quality.”可知答案。
2．In the third argument the author fears that we will ________ if we create life at will.
A．change the natural environment around us B．disturb the ecosystem in nature C．suffer from overpopulation
D．accelerate the extinction of animals
解析：选B 细节理解题。根据文章倒数第二段“We can see that an ecosystem (生态系统) ...I think it could lead to our extinction (灭绝)．”可知，B项正确。
3．According to the passage, what's the author's attitude towards cloning? A．Positive.
C．Indifferent.
B．Critical. D．Supportive.
解析：选B 推理判断题。根据全文内容可知，作者并不赞成克隆，对此持批评态度。
B
For many years, people have watched wild animals doing tricks in circuses and marine parks. Elephants parade around a noisy arena. They impress the crowd with tricks they have been forced to learn — things they'd never do in the wild.
At marine parks, orca whales — measuring up to 25 feet long and weighing thousands of pounds — splash (溅出水花) out
of the water and do amazing tricks, drawing cheers from the audience.
Sure, it's fun to watch these wild animals up close — but many people wonder if it's really fair to the animals? After all, an orca whale in the wild has the entire ocean as a home. They live in family groups and may travel 100 miles in a day. Is living alone swimming around in circles in a small pool a good life for an orca?
In the wild, elephants also live in close family groups. They travel long distances to find food. They're very smart and look after each other and play together — things they can't do as circus performers.
Today, more and more people are saying that things should change. They believe the animals deserve to live a more natural life and not be used for entertainment. And now some companies are beginning to listen.
In March 2015, Ringling Bros, and Barnum and Bailey announced that they would no longer use elephant acts in their circuses. And on May 1, 2016, the elephants performed their last show, signaling an end to a long history of elephants in circuses and traveling shows.
A year after the Ringling announcement, SeaWorld Theme Parks promised to give the orcas in their parks a better life as well. The company announced that it would begin to phase_out shows featuring orcas performing tricks. Instead, they will highlight (突出) more of the whales' natural behaviors. SeaWorld also said they wouldn't add any more captive (被俘的) orcas to their parks.
These are first steps toward putting an end to using captive wildlife for entertainment. And these changes were made after many people spoke out loud and clear to say that wild animals deserve to live wild and free.
语篇解读：马戏团里的野生动物表演为观众带来了很多乐趣，然而这种强迫动物表演杂技的做法对动物公平吗？
4．Why does the author mention elephants and orca whales in the first two paragraphs?
A．To introduce the subject. B．To show they are very smart.
C．To stress the great fun they bring us. D．To encourage readers to watch animal shows.
解析：选A 推理判断题。作者在第一、二段中提到大象和虎鲸表演杂技动作，引来观众的欢呼和喝彩，紧接着作者在第三段中写道“it's fun to watch these wild animals up close — but many people wonder if it's really fair to the animals？”由此推断，作者提到大象和虎鲸的表演是为了引出主题。
5．What does the underlined part “phase out” in Paragraph 7 mean? A．Put on. C．Gradually stop.
B．Figure out. D．Creatively improve.
解析：选C 词义猜测题。由第六段中的“they would no longer use elephant acts”和第七段中的“promised to give the orcas ... a better life”和“Instead, they will highlight more of the whales' natural behaviors”可知，海洋世界主题公园宣布将会开始逐渐停止虎鲸的表演；由此推断，phase out意为“逐步淘汰，逐渐停止”。
6．What would be the best title for the text? A．Last chance for animals B．Tons of fun: not for everyone
