Ques: Read the article and select the best answer. Article: What do you see from a handful of seeds? Some see green plants, some see blooming flowers, or just seeds. But one group of Shanghai students saw an opportunity to make money. Eight students from No 2 Secondary School Attached to East China Normal University started a virtual company selling different seeds and seed products. They successfully sold 28 pictures pasted with different seeds at a campus auction a week ago. The company, which has recruited around 20 student staff members, has earned over 2000 yuan in the past three months. "We donated part of the money to a poor school in the countryside of Anhui Province. It's great to realize our ideal of 'spreading love and culture with seeds' after many tests and lots of hard work," said Senior 2 Shi Chen, CEO of the company. Just like any other company, Shi's didn't develop smoothly. Shi and her young colleagues used to sell fresh flowers and old books, and later found seeds might be something that their company could engage in. They bought seeds of various plants and flowers at low prices from a local farm and sold them in schools or on streets. The creative students also made accessories and pictures with different seeds. With little business knowledge, the students had to learn new skills as the leaders of different departments, such as public relations (PR), sales and marketing. They persuaded a joint Sino-French company near their school to give them training in business management. "They helped us overcome our shyness. We also learned quite a lot of business theory. I found communication skills and teamwork are very important for my job" said Senior 1 Qian Yifei. The 16-year-old was elected as PR manager thanks to her talent for speaking. She is also in charge of after sales service, dealing with complaints and providing suggestions. As the head of the company, CEO Shi has a lot more to think about. First of all, she has to learn how to make her colleagues work efficiently as the company only opens at weekends due to all their studies. makes the company... Question: We can learn from the passage that _ . Options: A: the company is owned by 20 students. B: the company is over-night successful. C: the company sells fresh flowers and old books D: the company gets much help from other company selling seeds.
Ans: A

Ques: Read the article and select the best answer. Article: Everyone has those nights-you lie in your bed for hours, tossing and turning, totally unable to fall asleep. You wish you could just turn your brain off as if it were a light. That would make things much easier, wouldn't it? Now it looks like you are one step closer to this wild dream of yours-scientists from Oxford University, UK have just discovered the "switch" that tells the brain to go to sleep, reported Forbes. To understand the study, you first need to know that there are two mechanisms that regulate sleep. There's one that we're already familiar with --our body clock, which works in a 24-hour cycle based on the light changes throughout the day. The other one is what scientists call the sleep "homeostat ". This mechanism has nothing to do with daylight. Instead, it keeps track of the brain's waking hours and urges it to rest if it has been awake for a long time. "It is similar to the thermostat in your home. A thermostat measures temperature and switches on the heating if it's too cold," Professor Gero Miesenbock, who led the study, told The Telegraph. Our bodies use both of the mechanisms to regulate sleep. "The body clock says it's the right time, and the sleep thermostat has built up pressure during a long waking day," explained Miesenbock. There is no way that scientists can trick the body clock. But with the sleep homeostat, there might be something they can do. The researchers found that the sleep homeostat works by activating a specific group of nerve cells, or neurons, in the brain. They tested their theory on fruit flies by removing the neurons from the insects' brains. And as expected, they found that the flies without the homeostat neurons did not keep a regular sleep pattern anymore. Now that scientists have pinpointed the exact place in the brain-- or, the "switch"--that regulates sleep, they can begin investigating how to activate these cells at any given time so that people can be sent to sleep instantly. More importantly, figuring out how sleep mechanisms work may also help us to one... Question: What can we conclude from the article? Options: A: Generally, the sleep homeostat has less effect on people during the day than at night. B: There is little scientists can do to affect the way the sleep homeostat works. C: What makes us go to sleep at night is probably a combination of the two mechanisms. D: The more homeostat neurons there are in one's brain, the more easily one can fall asleep.
Ans: C

Ques: Read the article and select the best answer. Article: 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. Question: According to Zhou Jianliang we can know that _ . Options: A: on the moon the rover can't communicate with the lander B: sunlight is the necessary power for the rover and the lander C: Chinese technology has been regarded the most successful D: the lunar night can destroy the equipment on the moon
Ans:
B
