China's Jade Rabbit moon rover has " woken up" since it entered the lunar night two weeks ago. The moon rover, known as Yutu in Mandarin Chinese, and the Chang'e-3 lander were restarted by the Beijing Aerospace Control Center (BACC), China's Xinhua news agency said. It had been set to sleep for two weeks to ride out extreme climatic conditions and will finally undertake its scientific mission. The Jade Rabbit was " put to sleep" on 26 December at the onset of the first lunar night of the mission. One night on the moon lasts for around two weeks on Earth and during this time, temperatures fall to -180degC ---conditions too cold for the equipment to function in. There is also no sunlight to power the Jade Rabbit's solar panels. Zhou Jianliang, chief engineer with the BACC, explained: " During the lunar night, the lander and the rover were in a power-off condition and the communication with Earth was cut off. " When the night ends, they will be started up with the power provided by sunlight and resume operation and communication according to preset programmes. He added that the Jade Rabbit surviving the lunar night showed Chinese technology had proved successful. The Jade Rabbit and the lander compose Chang'e-3 landed on the moon on 14 December. With the landing, China became one of only three nations to soft-land on the moon, and the first to do so in more than three decades. Scientists said the mission was designed to test new technologies and build the country's expertise of space exploration. The Jade Rabbit will gather scientific data and capture images from the Moon. China was planning further missions planned to collect lunar soil samples and it is thought officials are looking to conduct manned lunar landings if they prove successful. What does the author intend to tell in the passage? A) Jade Rabbit wakes up to begin moon mission. B) Jade Rabbit was put to sleep on the moon. C) Jade Rabbit lost contact with the earth. D) Jade Rabbit is to undertake new mission.

This happened several years ago.But it has stuck with me so I wanted to share it. Every day on my way to work I would buy a newspaper from an elderly gentleman on the corner of the street.He would always smile and say,"Good morning."His smile always made my day. Most of the people who sell these papers are homeless or poor and they do it to make a few bucks. One day Charlie wasn't there!Someone else was in his place! This other guy told me Charlie was in the veterans' hospital. It troubled me all day long.All I could think about was Charlie being alone in the hospital.I never knew he was a veteran who had served our country.I just knew his smile always made my day. I asked my girlfriend if she would go with me to visit him and she agreed.When I showed up in Charlie's room he began to cry.He told us he had been feeling very lonely and was convinced no one would ever visit him.He said that we were his only visitors. We told him we were glad to do it and thanked him for all that he had done for others. I never saw Charlie after that,although I heard he moved to California.That was thirty years ago but I haven't forgotten my smiling friend.A big thankyou to those who serve our country and protect us and thank you Charlie,wherever you are! Why did Charlie cry at the hospital? A) Because he was afraid of his death. B) Because the doctor didn't treat him well. C) Because he had someone to visit him at last. D) Because he couldn't afford to pay the operation.

(Question)
Researchers Jose Cordova and Erich Astudillo have discovered a new molecule that kills the bacteria Streptococcus Mutans, long known to be responsible for breaking down sugars in food in the mouth, which damages tooth leading to decay . The new molecule they call "Keep 32" has been found to kill the bacteria. The two have applied for a patent on their discovery and have also begun a marketing strategy aimed at both oral care products and food products. They say either product, if left in the mouth for just 60 seconds ,will kill all the harmful bacteria in the mouth and keep _ at bay for several hours. If the new molecule passes health and safety tests, the two believe products using their new molecule should be on the market in as little as a year and a half. They expect the market for such a product to reach $300 million in just the first year. The two have been working together since 2005 using money from the Founder Institute and say the aim is to approve the process for creating the molecule they've discovered for big companies like Procter & Gamble, Colgate even candy companies such as Hershey's. In interviews, Astudillo has suggested that the two researchers are already heavily into discussion with several companies, some of which are interested in buying the patent once it is approved. Over the years many products have _ with announcement of reducing tooth decay and even the loss of teeth, but other than the introduction of fluoride into drinking water, not much progress has been made. If the announcement made by this new team proves true however, it could foresee a mark in saving the world of tooth decay as well as helping to improve the health for millions of people as tooth decay has been linked to many other health problems throughout the body including heart attacks. This passage mainly tells us that _ . A) many health problems are closely connected to tooth decay B) the discovery of a new molecule will greatly benefit health care C) two researchers are discussing their patent with companies D) researchers discover a molecule that can kill tooth decay-causing bacteria
