阅读下列材料，从每题所给的A、B、C、D四个选项中选出最佳选项。

Many people use the mobile phones as the alarm clocks and also use them to check e-mails before sleeping. It's a pity that these habits are becoming their sleeping problems.

Several years ago, my boss always played her mobile phone till very late and got badly ill because of that. Now she always leaves her phone in another room at night. And she asks her friends to do so. "I give each of my friends the same Christmas gift — an alarm clock. So they could stop using the phone as the alarm clock," she said.

If your mobile phone wakes you up in the morning, it may also keep you up at night. A study shows that people in mobile phone radiation mostly have sleeping problems. And according to a Swedish study, a quarter of young people in this country like having their phones around them. Most of them feel sorry for not answering messages. So they even have to answer messages to their friends before sleeping.

So what kind of people like to use mobile phones in their bedrooms better? A study has shown that three-quarters of people aged between 18 and 34 like to sleep with their phones near them better. That number becomes smaller in the middle age, but only people aged 65 and older like leaving the phone in another room when they are sleeping.

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项。

Australia is nearly as large as the United States, but most of it is too dry to live in. Around the edge(边缘) of this huge dry part are large sheep and cattle farms. A few of them are as large as the smallest states in America. Often the nearest neighbors are many hundred miles away.

The two-way radio is very important to people who live on these great Australian farms. It works much like a telephone. A person can listen to someone else talk and give an answer.

When these radios first came into use, the Australian government set up a special(专门的，特别的) two-way radio programme(节目). Then, people on the large farms could talk to a doctor hundreds of miles away. They could tell the doctor about someone who was sick, and the doctor could let them know how to care for the sick person.

Since the large farms were so far from towns, the children could not to go to school. Radio schools were set up for them in some places. At a certain time each day, the boys and girls turn on their radios and listen to teachers in cities miles away.

Families on the large farms wanted to give news to their neighbors. “Round robin(知更鸟)” talks by radio were started to keep families in touch with each other. They could talk about who was getting married or who was sick or who was going away. The men could talk about their sheep and cattle and how much money the markets would pay for them. In many ways the radio became a newspaper for the farm people of Australia.
