From the first use of the rocket to carry satellites into space to the setting up of space stations,human beings have been putting great effort into space research. And so far,we have achieved many successes. But there are still numerous tasks in front of us and we should not cease trying to progress. The international space station is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word,if we want to explore space more,the first thing we should do is to set up a space station. As the space station costs a lot of money,it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone,and it has tried to do so,but not very successful. So it _ many other countries to work on it together. Though it is still extremely expensive,it is much cheaper than doing it alone. It is really a job that needs everyone's effort and will benefit everyone. But even so, the funds needed are still a big problem. As for the USA,it seems that it has too many things to spend its money on. Although it is the richest country in the world,it has much debt every year. It has to make arrangements about its finance,and try to find a balance in all these issues. Which of the following is NOT a reason for countries' cooperation in building the international space station? A) That it requires a lot of money. B) That it needs everyone's effort. C) That it will benefit every participating country. D) That it is too far away from the earth.

Imagine that 7 out of 10 working Americans got fired tomorrow. What would they all do? It's hard to believe it would happen. But that is what the industrial revolution did to the labor force of the early 19th century. Two hundred years ago, 70 percent of American workers lived on the farm. Today automation has eliminated all but one percent of their jobs, replacing them with machines. But these workers did not sit, doing nothing. Instead, automation created hundreds of millions of jobs in completely new fields. Those who once farmed were then working in factories that produced farm equipment, cars, and other industrial products. It may be hard to believe, but before the end of this century, _ Yes, dear reader, even you will have your job taken away by machines. In other words, robot replacement is just a matter of time, First, speedy robots being able to lift 150 pounds all day long will carry boxes, sort them, and load them onto trucks. Fruit and vegetable picking will continue to be robotized until no humans pick outside of specialty farms. Next, The work of cleaning in offices and schools will be taken over by late-night robots. The trucks will be driven by robots. We need to let robots take over. They will do jobs we have been doing, and do them much better than we can. They will do jobs we can't do at all. They will do jobs we never imagined even needed to be done, and they will help us discover new jobs for ourselves and new tasks that expand who we are. They will let us focus on becoming more human than we were. What happened in the early 19th century? A) Some working Americans in factories got fired. B) Jobless workers had no choice but to sit there doing nothing at all. C) Many American workers had to leave factories to work on the farm. D) The industrial revolution caused many Americans to lose their jobs.

Ques: In a society where lung and breast cancers are leading causes of cancer death worldwide, early detection of the disease is highly desirable. In a new scientific study, researchers present astonishing new evidence that man's best friend, the dog, may have the ability to contribute to early cancer detection. Researchers show scientific evidence that a dog's extraordinary smelling ability can distinguish people with both early and late stage lung and breast cancers from healthy people. Researchers first discovered this in the case report of a dog warning its owner to the presence of a melanoma by constantly sniffing the skin lesion . Later studies published in major medical magazines proved the ability of trained dogs to detect both melanomas and bladder cancers. The new study is the first to test whether dogs can detect cancers only by sniffing the breath of cancer patients. In this study, five household dogs were trained within a short 3-week period to detect lung or breast cancer by sniffing the breath of cancer patients. The experiment consisted of 86 cancer patients (55 with lung cancer and 31 with breast cancer) and 83 healthy people. All cancer patients had recently been diagnosed with cancer and had not yet undergone any chemotherapy treatment . The dogs were presented with breath samples from the cancer patients and the healthy ones, captured in a special tube. Dogs were trained to give a positive identification of a cancer patient by sitting or lying down directly in front of a test station containing a cancer patient sample, while ignoring healthy samples. The results of the study showed that dogs can detect breast and lung cancer between 88% and 97%. Moreover, the study also proved that the trained dogs could even detect the early stages of lung cancer, as well as early breast cancer. The researchers concluded that breath analysis might become a potential of cancer diagnosis. The last sentence of the passage means_. A) doctors won't be worried about detecting cancers any more B) dogs will be the only way to detect cancers C) breath analysis can be used in diagnosing cancers in the future D) dogs can use its smell to identify people
Ans: C
Question: MADRID (Reuters)--Spain' s parliament voiced its support on Wednesday for the rights of great apes to life and freedom. Parliament's environmental committee approved resolution urging Spain to carry out the Great Ape Project (GAP), designed by scientists and philosophers who say our closest genetic s deserve rights limited to humans. "This is a historic day in the struggle for animal rights and in defense of our evolutionary comrades, which will doubtless go down in the history of humanity," said Pedro Poza, Spanish director of the Great Ape Project. The new resolution has cross-party support and it is thought they will become law within a year, making Spain the first nation to extend legal rights to apes. Under the new law, potential experiments on apes in Spain will be forbidden. "We have no knowledge of great apes being used in experiments in Spain, but there is currently no law preventing that from happening," Poza said. Keeping apes for circuses, television commercials or filming will also be forbidden.Housing apes in Spanish zoos, of which there are currently 315, will remain legal, but supporters of _ have said the conditions in which most of them live will need to improve vastly. Philosophers Peter Singer and Paola Cavalieri founded the Great Ape Project in 1993, arguing that "non-human hominids " should enjoy the rights to life and freedom and not to be mistreated. The Great Ape Project was probably set up to _ . A) protect great apes' rights B) research the great ape society C) save the endangered great apes D) study the development of the great apes
