    Contrary to popular belief, people who sleep six to seven hours a night live longer, and those who sleep eight hours or more die younger, according to the latest study ever conducted on the subject. The study, which has tracked the sleeping habits of 1.1 million Americans for six years, weakens the advice of many sleep doctors who have long recommended that people get eight or nine hours of sleep every night.

    “There's an old idea that people should sleep eight hours a night, which has no more scientific basis than the gold at the end of the rainbow,” said Daniel Kripke, professor of psychiatry(精神病学)at the University of California at San Diego who led the study published in a recent copy of JAMA Psychiatry.

    The study was not designed to answer why sleeping longer may be harmful or whether people could extend their lifespan by sleeping less.

    But Kripke said it was possible that people who slept longer tended to suffer from short-term absence of sleeping, a condition where weak breathing puts stress on the heart and brain. He also stressed that the need for sleep was similar to that for food, where getting less than people want may be better for them.

    The study quickly caused warnings and criticism(批评), with some sleep experts saying that the main problem of America's sleep habits was deprivation(剥夺), not sleeping too much.

    “None of this says sleep kills people,” said Daniel Buysse, a psychiatrist at the university of Pittsburgh Medical Center.

    “You should sleep as much as you need to feel awake, alert and attentive the next day,” Buysse added. “I'm much more concerned about people short-changing themselves on sleep than people sleeping too long.”

    “Sleeplessness produces a variety of health consequences that were not measured in the study,” critics said.

(1)、The traditional idea about sleeping is that ________.
A、people who sleep longer die younger B、people who sleep less than six or seven hours live longer C、people need to sleep less to keep healthy D、people need to sleep eight or nine hours a night

A、People can extend their lifespan by sleeping less. B、Sleeping longer may be harmful to people's health. C、People should sleep as much as they need to keep awake, alert and attentive. D、It is possible that people who sleep longer tend to suffer from short-term absence of sleeping.
(3)、“The gold at the end of the rainbow” mentioned in the passage shows that ________.
A、sleeping is quite valuable in our lives B、the traditional idea that people should sleep eight hours a night has no scientific basis at all. C、sleeping longer is as valuable as the gold at the end of the rainbow. D、the idea of long sleeping hours comes from the gold at the end of the rainbow.
(4)、What is the best title for this passage?
A、A new idea challenges the scientists B、Sleep less, live longer C、Sleep more, die younger D、A new idea about sleeping causes criticism

    Apple is to open a research lab in the southern Chinese city of Shenzhen, according to Tim Cook, its chief executive, as it seeks to boost sales in the country and improve ties with the authorities.

    Beijing has been encouraging foreign technology companies to carry out more high-end work on the mainland as part of efforts to revitalize local industry.

    It will be Apple's second facility in China. It already has a new research and development facility in Beijing.

    The two R&D centers were “aimed at strengthening relationships with local partners and universities as we work to support talent development across the country”, Apple said in a statement.

    A closer relationship with the Chinese authorities has been a priority following setbacks for the US technology company this year.

    The iPhone has been losing market share to high-end handsets made by local competitors including Huawei, Vivo and Oppo, which topped the rankings in the second quarter, while Apple languished in fifth place, according to Canalys data.

    Analysts said the announcement of the R&D centre was Mr. Cook's latest attempt to gain favour with Beijing, following the US group's $1billion investment in Didi Chuxing, the Chinese car-hailing company, in May.

    Apple has had to change its approach in China as it faces rising nationalism and high-quality local competition, according to Ge Jia, a tech blogger, who wrote yesterday: “It's time for Apple to cast aside their pride.” “Their previous strategy of only selling devices to China without leaving anything behind is not working any more and they are starting their process of localisation in China through the Shenzhen lab.”

    There are many fun, free activities that you can do as a family. All that is required is a bit of imagination and some time set aside for fun. And the best part is that these are the kind of memories a child will remember for a lifetime.

Family game night

    Find out any of the games that are already around the house. Kids often get computer games for Christmas or birthdays, and would love to have a chance to play with their family. Or, make up some games of your own. “Charades” is a fun game to play that will challenge a child to use his/her imagination. Divide the family into teams and let each team come up with words that the other has to act out.

Family art time

    Pick some time for the family to sit down and come up with their own masterpiece. It doesn't need to be just a drawing -- take some old magazines sitting around the house, let the kids cut out pictures and paste them into their own montage. Or, use items from nature. Let them use leaves, pine cones, twigs and whatever else they can find to create something from their imaginations.

Family Picnic

    Taking the family for a picnic is a great way for some fun that doesn't cost any money. If the weather is nice, take them to a park or playground and let the kids have a day of playing. Or, if it is the middle of winter and a foot of snow is on the ground, set up a picnic in the living room.

Family Field Trip

    A family field trip doesn't have to cost a dime. Ask a nearby farm if it would be alright to bring your kids out for a tour and to see some of the animals. Or take them to a park and make a scavenger hunt where they need to find certain items from nature. Ask a local business if you could bring the family for a tour to see how things work -- you might be surprised at the number of people who would be thrilled to share what they do with others, and it could be an interesting lesson for the kids.

    A minister was on a long flight from China to London. The first warning of the approaching problems came when the sign on the airplane flashed on: Fasten your seat belts. Then, after a while, a calm voice said, "We shall not be serving the drinks at this time as there is going to be something unexpected. Please be sure seat belt is fastened."

    Soon the storm broke out. One moment the airplane was lifted on terrific currents of air. The plane dropped as if it were about to crash.

    The minister believed that he shared the discomfort and fear of those around him. As he looked around the plane, he could see that nearly all the passengers were upset and alarmed. The future seemed ominous and many were wondering if they would make it through the storm. Then he suddenly saw a little girl. Apparently the storm meant nothing to her. She was reading a book and everything within her small world was calm orderly. Sometimes she closed her eyes and then she would read again. Then she would straighten her legs, worry and fear were not in her world. The minister could hardly believe his eyes.

    It was not surprising therefore that when the plane finally reached its destination and all the passengers hurried to leave, the minister walked up to the girl he had watched for such a long time. Having commented about the storm and the behavior of the plane, he asked why she had not been afraid. The girl replied, "Because my dad is the pilot, and he's taking me home."

    Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake.

    This robot looking like a helicopter(直升机), is called the detector-bot . It's about 4 meters long, and it took about 4 years to develop the model. Its main functions(作用)are to collect information from the air, and send goods of up to 30kilos, to people stuck in an earthquake.

    This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, "Unlike other automatic machines, the most important feature of this robot is that it doesn't need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3,000 meters, and as fast as 100 kilometers per hour. "

This robot has a different function — it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go.

    As well as a detector(探测器)that finds victims(遇难者)and detects poisonous gas, a camera is placed in the 40 centimeter long robot, which can work in the dark.

    Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids.

    Experts have said that the robots will enter production, and serve as part of the national earth- quake rescue team as soon as next year.

    Humans' invention of zero was vital for modern mathematics and science, but we're not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.

    Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.

    Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren't just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.

    In further experiments, the researchers showed that bees' understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators(捕食者)and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.
