Article: Looking back on China's road to outer space, people can easily find it has not been very smooth. In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years. After China's first satellite into the Earth's orbit in 1970 came four flights of unmanned Shenzhou missions from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China's second human spaceflight, was launched, with a crew of two astronauts. What's more, the landmark spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration. Meanwhile, China's moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world's first man-made satellite, China's first circumlunar satellite Chang'e 1 took off on Oct.24, 2007, which became another milestone in China's space achievements after the above-mentioned manned flights. Chang'e 1 was expected to fulfill four scientific goals, one of which was to probe mineral elements on the moon, especially those not existent on Earth. It's said that the lunar regolith is abundant in helium-3, a clean fuel that may support the Earth's energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the blasting off of Chang'e 2, China's 2nd unmanned lunar probe, marking another step forward in moon exploration. This time the aim is to test the key techniques of Chang'e 3 and Chang'e 4, as a preparation for a soft lunar landing in the future. With great expectations, people all over the world are looking forward to China's greater space achievements. Question: Altogether how many astronauts have made successful spaceflight by Shenzhou spaceship by now? Yes or no, is the answer "6"?
No

Article: The library is one of the most popular places at a western university.Students turn to it for research,conversations about class,and many other services. Compared with Chinese libraries,college libraries in the US and UK tend to offer more resources.A postgraduate at Yale University can borrow as many as 225 books at a time. In addition to borrowing books,there are online and electronic resources.These include a database search of popular and academic material,such as LexisNexis Academic,which offers items from newspapers and magazines. Although books and articles are the items that students ask for most frequently,some libraries provide audio and video recordings,maps and sheet music .At some schools,teachers and tutors put electronic copies of their teaching PPTs on the library web to give easier access for students. Another useful service in western college libraries is the Interlibrary Loan.This allows a student at one school to borrow books from another school.The loan request is made through the student's college library,which gets the book,gives it to the user,and arranges for its return. Technology has brought more services to students and has made libraries attractive.Some universities have services for students to send messages through the computer or mobile texts to ask the library staff for information. Earlier this year,Harvard University introduced a new Scan and Deliver service,allowing students to make requests for parts of books and articles.Requests made through the system are handled by library staff.The student receives an email with an Internet link to the scanned pages.The service is free and all material comes within four days. It used to be that libraries didn't allow food or drinks.But that rule is changing and many of them now contain a cafe so students can spend as much time as they want in the library. Actually,some US university libraries are now allnight affairs,or have at least one study room open all night. Question: Which of the following statements is TRUE? Yes or no, is the answer "Library staff play an important role in college library service."?
(Answer)
No

Ques: Article: Many people once thought that air pollution had a bad influence upon only the area immediately around large cities with factories and heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is nearly worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of factories and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide( ) in the air resulting from the burning of fossil fuels (coal and oil) is creating a"greenhouse effect" - holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water. Another opinion, less widely held, is that increasing tiny substances in the atmosphere are blocking sunlight and lowering the earth's temperature-a result that would be equally disastrous.A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will make up for each other and the world's temperature will stay about the same as it is now. Question: It can be inferred from the passage that _ . Yes or no, is the answer "lowering the world's temperature a little would lead to agricultural disasters"?
Ans: No

Article: When I was 16 years old, I made my first visit to the United States. It wasn't the first time I had been abroad. Like most English children, I learnt French at school and I had often been to France, so I was used to speaking a foreign language to people who didn't understand English. But when I went to America I was really looking forward to having a nice easy holiday without any language problems. How wrong I was! The misunderstanding began at the airport. I was looking for a public telephone to give my American friend Danny a ring and tell her that I had arrived. A friendly old man saw me looking like being lost and asked if he could help me. "Yes,"I said."I want to give my friend a ring." "Well, that's nice,"he exclaimed ."Are you getting married? But aren't you a bit young?" "Who is talking about marriage?" I replied. "I just want to give my friend a ring to tell her I've arrived. Can you tell me where there's a phone box?" "Oh!"he said."There's a phone downstairs." When at last we did meet up, Danny explained the misunderstanding to me."Don't worry," she said to me."I had many difficulties at first. There are lots of words which the Americans use differently in meaning from us British. You'll soon get used to all the funny things they say. But most of the time British and American people can understand each other!" Question: From the passage we can see that "give somebody a ring " _ Yes or no, is the answer "has two different meanings"?
No
