Carol has three sisters. All of them are very beautiful. Sometimes she feels very bad because she doesn't look like them at all. She is short and heavy and she doesn't have big eyes or beautiful hair.

As young girls, her sisters often go to parties on weekends but Carol always stays at home—reading books and doing the homework. She says it's her dream to go to university(大学).

Ten years later, Carol grows up. All her sisters get married(结婚) at a young age and don't live a happy life. But Carol is now a teacher in a university and she spends most of her free time taking trips. Every day her life is colorful.

Well, you see it won't matter if you are not beautiful but you must study hard all the time. That may be the only way if you want to make your dream come true.

Dear Mom,

If you wake up in the middle of the night, you might want to check the time and see how many hours you have left before 1 up. But this is a bad idea.

Looking at light outside, an electronic watch or a 2 , sends information to the brain to wake up. The biological clock helps 3 the timing (节奏) of bodily processes. Circadian rhythms* are important for managing sleep and how the human body 4 . One of the most important and well-known circadian rhythms is the sleep-wake cycle.

The circadian rhythm and sleep-wake system are sensitive (敏感的) to 5 , and even a quick look at light can make falling back to sleep more difficult. But even more 6 , checking the time can create a feeling of more stress. And that's not helpful for you to sleep again.

Dr Nerina Ramlakhan, a 7 and stress management expert suggests that checking the time every time you wake up will just lead to a more worrying night. Never check the time if you 8 during the night. It is completely normal to wake during the night. But if you're easy to wake at night, then checking the time can make you 9 how much sleep you will or won't have.

When you have too much stress, the body becomes sensitive. This process is not 10 for staying sleepy.

*Circadian rhythms are 24-hour cycles that are part of the body's clock.

 There are about 180,000 words in the Oxford English Dictionary, but most of us only know a few thousand of them. That's why we often want to get the answer of" how to improve vocabulary". Here are some ways to improve your vocabulary.

Watch English movies

 Watching the English movies is a vocabulary booster. If you see the movie of your favourite book, you will have a better understanding of the words in it. You read something and then you see it on the screen. You will remember better because you have a visual representation.

Get out of the house

 Going to new places and doing something new are great ways to build new knowledge. When you open your eyes to new people and things, you also get new words from them.

Join a book club

 In a book club, you have to spend some time reading. Read as many kinds of books as you can and you will learn more new words in different areas. Don't forget to write the new words down. Try to remember and use them.
