The first robot rover to land on the Moon in nearly 40 years, China's Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飞行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04：35 Beijing time on Saturday (20：35 GMT)．It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon's surface.
Ma Xingrui, chief mander of China's lunar programme, declared the mission (任务)a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China's ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang'e3 mission landed some 12 days after being launched atop a Chinesedeveloped Long March 3B rocket from Xichang in the country's south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13：00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球车) in Shanghai a few years ago it's a wonderful technological achievement to have landed，” Prof Andrew Coates, from UCL's Mullard Space Science Laboratory, told BBC News.
Chang'e3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod2, which was kept warm by polonium(钋)210. But the sixwheeled Chinese vehicle carries a more sophisticated payload(复杂的有效负荷), including groundpenetrating radar which will gather measurements of the lunar soil and crust.What does the text mainly talk about?

According to a recent article in The Wall Street Journal, we might all be braggarts(大话王) in this competitive society addicted to social networking.
Take a close look at your socialnetworking sites. Do you like to post photos of yourself in restaurants to show others what an exciting life you have? Or do you like to write about how happily in love you are? Or perhaps you are of the subtle type who constantly complain about jobs but really just want to impress others with your important position.
According to the results of a series of experiments conducted by Harvard University neuroscientists(神经科学家), the reward areas of our brain——the same areas that respond to “primary rewards” such as food ——are activated when we talk about ourselves. We devote between 30 to 40 percent of our conversation time to doing just that. Unfortunately, Bernstein says, some people can't tell the difference between sharing positive information that others might actually want to know and direct bragging. She suggests that bragging involves comparison, whether stated or implied.
“We are expected to be perfect all the time. The result is that more and more people are carefully managing their online images”. says Elizabeth Bernstein, a columnist with the Wall Street Journal.
But the issue is not limited to the Internet. In a fiercely competitive job market we must sell ourselves on multiple platforms and show that we are better than others. In fact, we have become so accustomed to bragging that we don't even realize we are doing it, says Bernstein. This is harmful to our relationships and puts people off.
Bernstein talked to some experts who said that people brag for all sorts of reasons: to appear worthy of attention; to prove to ourselves we are doing fine and that people who said we would fail are wrong; or simply because we're excited when good things happen to us.
“Feel sorry for them, because they're doing this unconscious, destructive thing that won't help them in the long run，” said Professor Simian Valier, a research psychologist at Washington University. The underlined word “subtle” in Para.2 is closest in meaning to “________”．
| A．hidden | B．apparent |
| C．outstanding | D．simple |
Which of the following is one of the features of braggarts?
| A．They control conversation and only talk about themselves. |
| B．They know well how to share positive information. |
| C．They selfpromote to stand out in their career. |
| D．They don't pay much attention to their online image. |
What can we infer from the passage?
| A．Braggarts make a good first impression but the effect decreases over time. |
| B．People who like bragging know what they are doing. |
| C．Braggarts always adopt comparison directly to show they are excellent. |
| D．They care much about the feelings of others when talking. |
Growers around the world are using new methods to grow grapes to make wine. They use natural and organic methods to control harmful insects and weeds instead of using chemicals. Now, a winery in Canada has adopted a natural way to control its grapevines (葡萄藤). The Featherstone Winery is in southern Ontario. The grapevines, like other plants, need to be cut every year.
Cutting grapevines must be done very carefully. Only a targeted area of leaves is removed from the lower part of the vines to help the grapes grow better. But at the Featherstone Winery, no man or machine does the cutting. Instead, the job is done by 40 little wooly lambs.
David Johnson owns the vineyard (葡萄园). He says he learned about using lambs while visiting wineries in New Zealand. The young lambs are perfectly designed to do the job. They eat the grape leaves on the lower parts of the vine. But they are not tall enough to reach the grapes. They only weigh about 22 kilograms, so they do not beat down the soil. And their waste makes good organic fertilizer. In addition, using the lambs costs much less than hiring workers to cut the vines for seven weeks in summer. And when the cutting is done in August, the lambs become tasty dishes.
Mr. Johnson says he had a difficult time finding enough lambs to do the job. There are about 50 million lambs in New Zealand. But there are not nearly as many in Ontario. Also, some organic pesticides (杀虫剂) are harmful to lambs. And the lambs must be watched to make sure they do not eat too much of the grapevines.
David Johnson says the lambs help him carry out his environmental ideas about farming. They are lovely and peaceful and he likes having them in his vineyard. People visiting the vineyard also enjoy watching the lambs do their job.Farmers who grow grapes with natural and organic methods ________.
| A．don't cut grapevines every year |
| B．don't use chemicals to control harmful insects and weeds |
| C．don't need to control harmful insects and weeds |
| D．don't use organic fertilizer |
In order to help the grapes grow better, growers ________.
| A．only have to remove the dead leaves |
| B．need to remove a specific area of leaves |
| C．shouldn't remove any part of the plants |
| D．should let little lambs do the cutting |
Paragraph 4 is mainly about ________.
| A．the future of getting lambs to do the cutting |
| B．the worries about using organic pesticides |
| C．the ways to get lambs to do the cutting |
| D．the problems related to lambs doing the cutting |
We can infer from the passage that David Johnson ________.
| A．owns several wineries in Canada |
| B．buys lambs from New Zealand |
| C．is concerned about protecting the environment |
| D．loves keeping lambs instead of farming |
