Sometimes, we see some people reading books while biting their nails (咬指甲). According to the BBC(英国广播公司), up to 45 percent of teenagers bit their nails. There is not an exact answer to{#blank#}1{#/blank#}   why people bite their nails. But most commonly, nail biting is said to be a nervous habit. It is done  {#blank#}2{#/blank#}  of stress(压力), boredom or excitement.

 What's more, a report says that people with higher levels of intelligence(智力)  {#blank#}3{#/blank#}  biting their nails at an early age. It believes that compared  {#blank#}4{#/blank#}  common person,  {#blank#}5{#/blank#}   with higher levels of intelligence may feel higher levels of stress more easily.

 This habit is   {#blank#}6{#/blank#}   for the biters. It can give them red or sore fingertips. And long-term nail biting can affect(影响)   {#blank#}7{#/blank#}   nails grow.

 But don't worry! There are many   {#blank#}8{#/blank#}  to stop biting your nails. First, keep your nails clean. The more you focus on taking care of your nails, the  {#blank#}9{#/blank#}   likely you may bite them again.

Last night I had a wonderful dream. I {#blank#}1{#/blank#} that I turned into a good swimmer.
In my dream, the weather {#blank#}2{#/blank#} fine and I came to a nice beach. There were few people on the beach and I {#blank#}3{#/blank#} to swim in the sea. While I was swimming, some {#blank#}4{#/blank#} fish followed me all the time. When I stopped, they came to swam {#blank#}5{#/blank#} me. Then, one of the fish began to talk with me. It {#blank#}6{#/blank#} Chinese, too! We had a wonderful conversation. Soon we became good {#blank#}7{#/blank#} and it invited me to visit the place where they lived.
{#blank#}8{#/blank#} I heard a voice, “Weiwei, it's time to get up! Breakfast is ready!” It was Mom's voice. Just then I woke up from my sweet dream {#blank#}9{#/blank#} had to face the real world again.
My dream was {#blank#}10{#/blank#} like a cartoon film, wasn't it?

    "Dreams (梦 ) may be more important than sleep. We all need to dream," some scientists say.
     Dreams take up about one quarter of our {#blank#}1{#/blank#} time. People have several {#blank#}2{#/blank#} each night. Dreams are like short films. They are usually in color. Some dreams are {#blank#}3{#/blank#}  old films. They come to us over and over {#blank#}4{#/blank#} . That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer.
    Some people get new ideas{#blank#}5{#/blank#}  their work from dreams. They may have been {#blank#}6{#/blank#}  about their work all day. These thoughts can carry over into dreams.
    Sometimes, we {#blank#}7{#/blank#}  with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear (消失) {#blank#}8{#/blank#} from memory (记忆).
    Too much dreaming can be harmful (有害的). The {#blank#}9{#/blank#}  we sleep, the longer we dream. The mind is hard at work when we dream. That is {#blank#}10{#/blank#} we may have a long sleep and still wake up tired.

Jack: Annie, I'm a little nervous. I have to finish reading a book and give a report next Monday.

Annie: That doesn't sound too bad.

Jack: But I'm a very slow reader.

Annie: For the {#blank#}1{#/blank#} time, just read quickly to get the main ideas. Don't read word by word, read word groups. 

Jack: But I don't understand many of the words. I have to use a {#blank#}2{#/blank#}.

Annie: Try to guess a word's {#blank#}3{#/blank#}by reading the sentences before and after it. You probably understand more than you think.

Jack: That sounds difficult!

Annie: Well, be patient. It takes time. You can become better by {#blank#}4{#/blank#} something you enjoy every day. The more you read, the {#blank#}5{#/blank#} you'll be.
