Stop! Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noisy. Noise is loud and unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes, tractors and so on. And, to some people, rock bands are also noise.
What happened to people who live near noisy machines or use them over a period of time? Doctors find that these people have trouble in sleeping, But, most important, constant loud noise can cause a loss of hearing.
Scientists use a unit of measure called a decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level causes the greatest hearing loss.

Jia Meng used to keep a diary (日記) in Chinese. But one year ago, the 14-year-old girl from Hei Longjiang began to write her diary in English, because Jia found her mother was reading her diary secretly. She changed the language because her mother can’t read English. “It’s like killing two birds with one stone.” said Jia, “My privacy (隱私) became safe and my English improves a lot.”
Jia’s mother is not the only mom who reads her child’s diary. Recently, Renmin University of China had a national survey among over 2, 3000 parents. The results show that  40% of parents read their children’s secrets. That’s why, like Jia, many teenagers try to find ways to protect(保護(hù)) their privacy.
Wu Lei, 15, of Shanxi, keeps a diary, too. But he doesn’t write in on paper. He writes online which he thinks is perfectly safe because his parents “know nothing about the Internet.”
Lu Huan, 13, of Guangdong, said her parents always secretly listened to the talk between her friends and her on the telephone in their room. To solve this problem, Lu asked her parents to buy her a mobile phone.
“Parents want to know what is going on in their children’s lives,” said Shao Xiazhen, a teenage expert in Beijing. “ But sometimes they go about it the wrong way.” Shao suggested to teenagers that instead of hiding their secrets, talking to parents is a better solution. “If your parents know that you are safe, they’ll let you keep your secrets.”
根據(jù)短文內(nèi)容,判斷下列句子正誤。正確的用“A”表示,不正確的用“B”表示。

We can’t live without love and we know what love is, but we don’t say only humans know what love is. Yes, it’s impossible for animals to do some things because of their physical body. However, sometimes some of them might be able to show us the love that we have forgotten on our “busy road”, just like the following story.
A dog, was knocked down by a car and died in the middle of the road. Later, another dog ran beside the body of the dead dog and he tried to wake his friend up using his legs. When his effort to wake up his friend failed, he tried to push his friend to the roadside. But his friend was too heavy for him to push.
Though traffic was busy and dangerous, he wouldn’t want to go away from his friend, just standing beside his friend shouting and crying.
A lot of people saw this story and were very touched (感動(dòng)的). Even a dog can show his loyalty (忠誠) and love to his friend, what can our humans do?
