【題目】Daily homework is necessary, __________ too much homework may bring harm to students.

A. soB. butC. forD. or

A. so因此；B. but但是；C. for為了；D. or或者。根據(jù)Daily homework is necessary每天做作業(yè)是必要的，可知，這是說作業(yè)的好處。與后面的句子__________ too much homework may bring harm to students. 這是說作業(yè)的壞處，前后事實(shí)相反，因此應(yīng)該用轉(zhuǎn)折連詞but。故選B。

【題目】 Your third year of middle school was probably a difficult and busy time. You may have had trouble getting enough sleep. We all know that not getting enough sleep is not good for our health. But it has be found that less sleep could even cause you to have fewer friends, the Guardian reported.

According to researchers from the University of California, people who don't get enough sleep are less willing to socialize(社交)with others. They are simply too tired to go out.

The researchers did a small study. They tested 18 young people who had just had a good night's sleep -as well as tested them again after a sleepless night. The participants watched videos of people with expressions walking toward them. When the person on the video got too "close" to them, they pushed a button to stop the video, which recorded how close they allowed the person to get.

The results showed that the participants kept the person at a further distance if they hadn't gotten enough sleep. They might think the person intruded their personal space. But when the participants got a good night's sleep, they allowed the person to get much closer to them.

According to a lead researcher Matthew Walker, the less sleep you get, the less you want to socialize with others. In turn, other people may think you look strange and stay away from you. This can make you feel lonely and cause you to sleep even less. It becomes a vicious cycle(惡性循環(huán)).

So if you want to be a more sociable and popular person, seeping well might help. "One night of good see makes you feel more outgoing and confident." Walker told the Daily Mail.
