【題目】根據(jù)短文理解，選擇正確答案。
The wind tried pushing Colin to the ground. It felt as if Colin's news-bag was full of potatoes.
Maybe it had to do with the news Dad read before Colin left. The morning headlines（標(biāo)題）were full of the usual sad stories.
“No good news again!” Dad said.
Car accidents! House burns! Storm damage（損害）!
Colin moved quickly from house to house leaving papers in the mailbox. He wished he could bring only good news to his family, also to his friendly neighbours. “How could I make things better for everyone?” he wondered.
Colin noticed Alice coming. She only had one real eye. The other was made of glass. He liked Alice even if many others laughed at her. He didn't realize how much it helped her, having a friend like Colin.
Each time Colin left a paper by a customer's door, he thought, “How could I make some good news?”
Colin gave his usual cheerful “Hi” to everyone on his way. His smile was like the rising sun.
Someone was crying and he ran to where a little boy had fallen and hurt his leg. Colin calmed him down until the boy's mother arrived.

He continued on his way, but he didn't feel tired. It was fun doing what he usually did—helping others.
He raced up the street to his last customer. Mrs. Williams saw Colin coming and had peanut butter cookies as a treat for her favourite paperboy. She wondered why such a lively boy always had time to chat with an old lady.

【題目】閱讀下面短文，根據(jù)短文內(nèi)容完成句子。

Most of us use alarm clocks to wake up at the right time for school or work. We look at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine. We can’t look at a clock for the right time for these activities. We must listen to the clock inside our bodies: the biological (生物的) clock.

Barbara Wells exercised every morning. She woke up at 6:00 a.m. She ran about two miles before she went to work. But Barbara’s legs and back started to hurt. She did some exercise before she ran. But her legs and back still hurt. She ran slower, but the pain didn’t stop. Barbara talked to her doctor. The doctor said, “Don’t run in the morning. Try to exercise later in the day. That is the time when your body is at the right temperature for exercise after work.” Her legs and back didn’t hurt anymore.

Today, doctors are learning more about chronobiology (生物鐘學(xué)), the study of biological clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep on time every night and to eat only when they’re hungry. Also, doctors discovered that some illnesses, such as heart attacks, occur (發(fā)生) most often in the morning. This information tells them that the best time to take heart medication (藥物) may be at night. When patients take heart medication at night, they may prevent a heart attack in the morning.

Many doctors believe chronobiology (生物鐘) can help us live healthier lives. It may be the right time to listen to these doctors!

【1】We all have _________ clocks inside our bodies.

【2】Barbara Wells ran _________ every morning before she went to work.

【3】Barbara Wells’ legs and back got well by _________.

【4】What is the right time for the person who has a heart attack to take heart medication?

【5】Many doctors believe _________.
