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.

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.

D．They don't pay much attention to their online image.
3.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.

Pupils remember more and behave better when 3D images areused in lessons，research suggests.They are quicker to learn andabsorb new concepts，and display higher levels of concentration.
Professor Anne Bamford，of the University of the Arts，London，studied the effectiveness of 3D content in 15 schools across seven countries，including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks，improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿动作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding，increased attention span, more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology90 percent of those in the study had seen a 3D film.Schools would need 3Denabled projectors(投影仪)，laptops with good picture capabilities,3D software and glasses for children to introduce animations(动作) into classrooms.
But Danny Nicholson，an educationist，said the technology would be impractical to use inschools and could be costly.He said，“While I think the idea of 3D technology is very interesting，I worry that 3D is a bit of an expensive gimmick(小玩意儿)．There are a few cases where a true3D image might help，but most of the time，good 2D models that can be moved would be just aseffective.”
In the US，one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
1.What is the main idea of the first three paragraphs?
A．There are slight differences between 3D and 2D images.
B．Pupils perform better when 3D images are used in classes.
C．Schools have difficulties in making full use of 3D technology.
D．3D technology is always more effective than 2D technology.
2.Danny Nicholson holds the view that 3D ________.
A．is of no help in classes
B．has a bright future in classes
C．is more practical than 2D models
D．may not be affordable for schools
3.What can we learn from the last paragraph?
A．3D technology will replace 2D models in the future.
B．Many pupils are now more Interested In science than before.
C．Teachers will use the 3D technology through specific training.
D．3D will soon be put into use in one school district in Colorado.
4.The underlined word “engrossed” in the last paragraph means ________.
A．absorbed B．annoyed
C．relaxed D. confused
