Read the following article and answer the question. Article: Chinese space trainer Wang Yuan has been chosen as one of the volunteers for the Mars-500 test project. He was very happy to be chosen and will accept the meaningful challenge  Another five volunteers are all space lovers., including three Russians, an Italy-Colombian and a Frenchman. They are about to feel what it's like to travel to Mars, only without leaving the earth. They are locked up together for a year and a half under a similar condition to the red planet during the whole process. So the experiment is called Mars-500. When reporters asked what they would miss most during the 520-day special life, French trainer Charles said:"For me, it will be mainly my family, the sun and fresh air." The Mars-500 test will be in a special building in Moscow, Russia. Although the people won't leave the building, they will fell as if they are on a real trip to the Mars. The most difficult thing will be to be separated  from the people that they used to live with. The trainer won't see sunsets, sunrises, won't feel rain for 18 months. That will be hard. The main task is to study the "Man and environment". It'll care about the astronauts' getting experience and physical effects. The 520-day-test is divided into three parts,the first 250days to Mars, the middle 30days of landing on Mars, the last 240 days to return to the earth. Everyone will stay there alone for a long time and will work lonely. They will have to make decisions themselves and only then report to the earth, and the earth will tell them whether they do the right thing or not. Each astronaut is preparing for the great challenge. It is learned that they will be launched early in June. And the experiment will end in November 2011. Question: _   members were chosen as volunteers. Answer:

Answer: Six


Read the following article and answer the question. Article: For 13-year-old Brooke Martin, seeing her golden dog Kayla has become much easier, even when she's not at home. Martin made a kind of machine--iCPooch. It allows pet owners to video chat with their pets and sends food from other places.2-1-c-n-j-y When a dog owner puts the iCPooch app on a phone, he or she can connect to the iCPooch machine at home and start talking. The owner's image  and voice will be on the screen. When the owner pushes a button on the iCPooch app, the machine will give the dog some food that has been stored inside the box. How could Martin come up with the idea? The idea came to the Washington girl when she took a business class last year. That led her to think about helping her pet Kayla. Kayla always looked sad when she was left alone at home."I wanted to know how you could talk to your dog if you were not at home. And what if you were able to give them a treat while you were away?" Martin explained her idea. Now Martin and her family have set up a company. They've had investments   from businessmen and asked a factory to make the product. They expected to sell 8,000 products by the end of 2015. Martin is satisfied  with her success. "A year ago, I never thought that I would be able to start a business, or even having an idea for a business," she said. "I've learned that we are supposed to hold on to your dreams." Question: Kayla felt   _   when she was left alone at home. Answer:

Answer: lonely


Read the following article and answer the question. Article: Teachers say the digital age has had a good and a not-so-good influence on the American teenagers. More than 2,000 high school teachers took an online survey. 75 percent of the teachers said the Internet and digital search tools have had a "mostly good" use for their students' research habits and skills, But 87 percent agreed that these technologies "make the students not have enough attention." And 64 percent said the technologies "do little to help them in courses." Judy Buchanan is a director of the National Writing Project. Ms. Buchanan says digital research tools are helping students learn more, and learn faster. Teachers really like these tools, because they are ways to make some of learning exciting. Young people enjoy using these tools. And the goal is to help them become creative students of meaningful work, and not just that kind of copyist. But one problem the survey found is that many students don't have a good understanding of how to use the digital knowledge well. In other words, they trust  too much of the information. Judy Buchanan says these students have not developed the skills they need to tell whether the online information is good or bad. Another problem the survey found is something that might not seem like a problem, at all, being-able to quickly find information online. Teachers say the ability of their students to work hard to find answers is becoming weaker. They say students depend too much on search engines   and do not make enough use, of printed books or research, librarians. Besides, many teachers are also worried about the problem that the Internet makes it easy for students to copy work done by others, instead of using their own abilities. Question: Teachers like the digital search tools because they can  _ Answer:

Answer:
