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. Question: It can inferred from the passage that _ . Options: A: China had made great achievements in 10 years B: no country can be equal to China in exploring space C: scientists can get more proof to research the moon D: the soil from the moon has been taken to China

Ques: Read the article and select the best answer. Article: Analysis of the composition of quicksand shows that there are four key ingredients--sand, obviously water, clay and salt. Together these materials form a structure resembling a house of cards, with large water-filled gaps between the sand particles, which are loosely glued in place by the clay. As long as it's left alone, the structure remains stable. But as soon as it's disturbed, by stepping on it, the clay changes from a jelly-like consistency to a runny liquid. The effect is the same as stirring a pot of yoghurt. Liquefying the clay makes the quicksand about one million times runnier, and the whole house of cards comes tumbling down, with you inside it. Very quickly, the sand sinks to the bottom and the water floats to the top. This is where the salt comes in. When there's enough salt present, as soon as the clay particles liquefy, electrical charges make them begin to stick together to form bigger particles and these also settle with the sand. Quicksand is a mixture which looks like solid, but behaves more like a liquid. Despite its murderous reputation, quicksand does not such people under and swallow them, although it can hold a person in firm grip. The human body is more buoyant in quicksand than in water, and sooner or later anyone trapped in it will float. Unlike most liquids, quicksand's viscosity, or "runniness" can suddenly change if it comes under pressure, for example under a human foot. The surface gives way and the victim quickly sinks in up to the knees, surrounded by an area of dirty things that turns semi-solid around its victim. Escaping from the quicksand's grip requires a large amount of force. Without something solid to pull at, people often find they are stuck fast. Pulling at one leg simply makes the other one sink further. So how do you escape from quicksand's control? Stay still and call for help. Staying still stops you sinking any further, until--with luck--help arrives on the scene. If no one appears and you need to draw yourself out, gently lie down on your back until your... Question: Which ingredient of the quicksand make someone trapped in it stuck and stuck fast? Options: A: Sand B: Clay C: Water D: Salt
Ans: B

Ques: Read the article and select the best answer. Article: As the only physician in a small local clinic and hospital, Katrina Poe sees dozens of patients on any given day. She's on call at the hospital in Kilmichael every day, and she gets little time with her sons, aged 3 and 3 months. But the country doctor doesn't complain about her job. It's the one she chose for herself 25 years ago while she was a fifth-grader in Kilmicahael. The daughter of two workers in a town that had produced only two other doctors, Poe might not have been expected to go to college at all, let alone medical school. But it was a challenge at first, being the town's first female and first black doctor. She even had patients who refused to see her at first. But a lot of those patients who were unwilling in the beginning are now some of her most favorite patients and have accepted her, finally. Many patients, in fact, now refuse to seek health care elsewhere. Though she's working at least 80 hours a week, Poe is sorry that she sometimes has to turn patients away. "I just can't see everybody," she says. "I'm seeing patients after hours, so it's just very busy." In addition to her work at the hospital and clinic, Poe cares for all residents of the local nursing home and the local mental health facility during monthly visits. "This town and the little hospital are fortunate to have her," says Calvin Johnson, Poe's husband. He says it is without a doubt "the love and support of the people" that make living in Kilmichael worthwhile for the family. In recognition of her services to rural medicine, the Texas-based physician staffing firm Staff Care Inc. named Poe, 35, the "2005 Country Doctor of the Year." Question: When Katrina Poe began her work at the beginning, it was difficult because _ . Options: A: she was not accepted by the local people B: she was poor in medical skills C: there were few patients in the town D: the town had other good hospitals
Ans:
