Science and technology makes our life easier and better than before. For example, a pair of shoes that helps you run faster and jumps higher, a cup that keeps your drink warm all the time, or a cute robot that talks to you, just like a human. The iPhone X is a “dream come true”, according to Apple. It does have some eye-catching selling points. The biggest selling point is Face ID. It can help users unlock their phone and pay for things just by looking at their smart phones.

According to Apple, Face ID has to do with a camera system(系统) called TrueDepth. When the camera system sees a person’s face, it “maps” the face with 30,000 invisible dots (看不见的点). Then the system creates and saves (保存)the model of the face in the phone.

The next time a person looks at the iPhone X, the same dots will compare his or her face with the saved model. If the two match, the phone unlocks. This happens in less than a second.

Apple says that the system is smart. So if you change your hairstyle, put on sunglasses, or use the phone in the dark, then it will still work.

But Face ID may not work with twins. According to Apple, the chance(机率) of someone unlocking your iPhone X by using Face ID is one in a million. Twins will make the statistics (数据) fall down, so you would really need to make a password for twins.

Apple also says that Face ID only unlocks when you look at it. So if you are sleeping or just taking a look at the phone very quickly, then it won’t unlock.

“You say your hair is gone?” Jim said like an idiot (白痴).

“You needn’t look for it,” said Della. “It’s sold, I tell you - sold and gone, too. It’s Christmas Eve, boy. It’s time for gifts. Be good to me, for it went for you. Maybe the hairs of my head were numbered,” she went on with a sudden serious sweetness, “but nobody could ever count my love for you.”

Jim drew a package from his overcoat pocket and threw it upon the table.

“Don’t make any mistake, Dell...” he said, “...about me. I don’t think there’s anything that could make me like my girl any less, no matter what hair style you have. But if you’ll open that package you may understand how I felt at first.”

She opened the package with her white fingers quickly and lightly. And then an excited cry of joy; and then, alas! a quick change to uncontrollable tears.

For there lay the combs - the set of combs (发梳), side and back, that Della had dreamed of for long in a Broadway window. Beautiful combs with jeweled rims (边缘)-just the color to wear in her beautiful hair. They were expensive combs, she knew, and her heart had always wanted them. But there was no hope of having them. And now they were hers, but the hair was gone. But she hugged them to her bosom (胸口), and at last she was able to look up with dim (黯淡的) eyes and a smile and say: “My hair grows so fast, Jim!”

Why is that many teenagers have energy to play computer games until late at night， but can't find the energy to get out of bed in time for school？ According to a new report， today's teenagers are getting so little sleep but their health is in danger．

This raises serious questions about whether being short of sleep is influencing children's ability to pay attention at school． Research has shown that losing even just half an hour's sleep at night can have deep influences on how children perform the next day．

So why aren't teenagers getting enough sleep？Some experts suggest that televisions， computers and mobile phones in children's bedrooms may cause problems．Instead of reading a book at bedtime，children are playing computer games，surfing the web，sending messages， or watching television．As these new pre-sleep activities have become more common，more traditional ones such as reading have become less，Dr．Luci Wiggs，a researcher at Oxford

University's Section of Child and Adolescent Psychiatry said，“One of the problems with these pre-sleep activities is that they do not have clear start and end times which leads to being short of sleep．”

Research has shown that teenagers have different sleep patterns from adults．Human bodies produce melatonin（褪黑激素）to help fall asleep． Most adults start to produce melatonin at

about 10 pm，while teenagers only begin to produce it three hours later．It is possible that this delay in melatonin production is caused by the behaviors of teenagers such as playing with phones late at night．

Problems about sleep- who needs how much and when -are usually connected to students' achievements． But modern brain researchers say it is time that more schools wake up to both biological and social facts and make a better timetable for their teenager students．

D.teenagers shouldn't watch TV before they go to sleep．

3.What does the underlined word 'delay' mean？

A.Rushing． B.Changing． C.Putting off． D.Cutting off．
