[Q]: Article: Three astronauts returned to Earth safely on Wednesday after a successful 15-day mission , marking another step forward towards the country's goal of building a manned space station by 2020. Zhang Youxia, commander-in-chief of China's manned space program, said the Shenzhou X mission was a "complete success". The Shenzhou X landed safely in north China's Inner Mongolia Autonomous Region at about 8:07 a.m. on June 26, 2013. All three astronauts were in good physical condition. Nie Haisheng, commander of the Shenzhou X crew and a second-time space traveler, was the first to get out of the bowl-like module , followed by Wang Yaping, the only female astronaut of the mission, and Zhang Xiaoguang. During a brief welcoming ceremony held at the landing area, the astronauts waved happily to a crowd consisting of officers, the search and recovery team, and health personnel. "It feels really good to be back home," said astronaut Nie Haisheng. "We are dreamers, and we have now realized our dream," said Zhang Xiaoguang. "Our space dream knows no limit, and our hard work will never stop," he said. Compared with its previous mission Shenzhou IX last year, the Shenzhou X is no longer experimental but considered an applicable shuttle system for sending astronauts and supplies to orbiting modules. The mission aims to further test technologies designed for docking and supporting astronauts' stay in space, as well as to use new technologies related to the construction of a space station. In its 15-day journey in space, Shenzhou X docked with the orbiting space lab Tiangong-1 twice, once through automatic operation and the other manual .The Tiangong-1 space lab has been in orbit for more than 600 days. It's designed to work for two years. The module is considered the first step in building a permanent space station in the future. And the astronauts spent 12 days in Tiangong-1, where they conducted space medical experiments, technical tests and gave a science lesson to students on Earth on June 19 about basic physics principles. The lecture was the second video class sent from space, with US astronaut Barbara Morgan's 25-minute class being the first in 2007. China is the third country after the United States and Russia to acquire the technologies and skills necessary for space rendezvous and docking procedures, as well as supply manpower and material for an orbiting module via different docking methods. Previous docking procedures conducted between Shenzhou-type spacecraft and the orbiting space lab included two automated dockings by the unmanned Shenzhou-8 in 2011 and both an automated and manual docking by the manned Shenzhou-9 in 2012. Since its first manned space space mission in 2003, China has sent ten astronauts and six spacecrafts into the space.
Question: According to the passage, the Shenzhou X _ .

[Q]: Article: With fifteen years prefix = st1 /Britainand other nations should be well on with the building of huge industrial complexes for the recycling of waste . The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful . Even the most dangerous and unpleasant wastes would provide energy if nothing else . The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out . The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city . This plant would recycle not only metal such as steel , lead and copper , but also paper and rubber as well . Another new project is being set up to discover the best ways of sorting and separating the rubbish . When this project is complete , the rubbish will be processed like this : First , it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed ; then it will pass through a powerful fan to separate the lightest elements from the heavy solids ; after that founders and rollers will break up everything that can be broken . Finally , the rubbish will pass under magnets , which will remove the bits of iron and steel ; the rubber and plastic will then be sorted out in the final stage . The first full-scale giant recycling plants are perhaps fifteen years away . Indeed , with the growing cost of transporting rubbish to more distant dumps , some big cities will be forced to build their own recycling plants before long .
Question: The phrase "be well on with ......" (Para .1) most probably means_.
Options: (A) have completed what was started (B) get ready to start (C) have achieved a great deal in (D) put an end to
[A]: C

[Q]: Article: Old age may not sound exciting.But recent findings offer good news for older pepole and for people worried about getting older. Researches found that people become happier and experience less worry after they reach the age of fifty.In fact,they say by the age of eighty--five,people are happier with their life than they were when they were eighteen years old. The findings came from a survey of more than 340,000 adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time,the people were between the ages of eighteen and eighty--five.The searches asked questions about emotions like happiness,sadness and worry.They also asked about mental or emotional stress. Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty--two and twenty--five.The findings showed that stress levels dropped sharply after people reached their fifties.Happiness was highest among the youngest adults and those in their early seventies.The people least likely to report feeling negative emotions were those in their seventies and eighties. The study also showed that men and women had similar emotional patterns as they grew older.Hower,women at all ages reported more sadness,stress and worry than men.Researchers say they do not know why happiness increases as people get older.One theory is that,as people grow older,they grow more thankful for what they have and have better control of their emotion .They also spend less time thinking about bad experiences. The researchers also considered possible influences like having young children,being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well--being related to age.
Question: How did the researchers find older people happier?
Options: (A) They did a series of experiments. (B) They made a written survey about the old people. (C) They interviewed people of different ages face to face. (D) They telephoned people between the ages of 18 and 85.
