One day, I was walking in the street when I noticed a woman {#blank#}1{#/blank#}(come) up to me with a nervous smile and said,“Sir, can you help a person out? I haven't eaten for almost two days.” I handed {#blank#}2{#/blank#}(she) a few quarters and watched her walk away.

    That area was so poor and {#blank#}3{#/blank#}(rule) by drugs and crimes. I walked to the corner and stopped by the door of the ATM machine. Then I {#blank#}4{#/blank#}(walk) inside and made sure that no one came in behind me.

    I put my card into the machine and deposited my money with a sigh of relief.60.{#blank#}5{#/blank#} I turned to leave, I saw a wallet sitting on another machine. I had a look at it. The name on the license was one I could not pronounce, but whoever he was, he was going to get into a panic over a wallet {#blank#}6{#/blank#} his identification in it being lost in this city.

    I put it in my pocket and went home. In my apartment, I checked the online phone book {#blank#}7{#/blank#}(find) out whether there was someone who matched the name on the cards in the wallet, but without luck. I picked up the bank card and had {#blank#}8{#/blank#} thought. Because I wanted to help the guy, I called his bank. But the girl over the phone said they could not give out any personal information about their clients. So I left my contact information with her and asked her to tell the {#blank#}9{#/blank#}(own) to contact me. Two days later, a very {#blank#}10{#/blank#}(thank) gentleman appeared at my office and I gave him back his wallet.

    Not all memories are sweet. Some people spend all{#blank#}1{#/blank#}lives trying to forget bad experiences. Now American researchers are developing a pill,{#blank#}2{#/blank#}will help people forget bad memories. The pill is planned to be taken immediately after a{#blank#}3{#/blank#}(frighten) experience. They hope it might reduce, or possibly erase, the effect of painful memories.

    However, the new research has caused a lot of argument. Supporters say bad memories may ruin people's lives. They come back{#blank#}4{#/blank#}us when we don't want to have them in a daydream or nightmare(噩梦). They usually come with very painful feelings. The pill can help to reduce many{#blank#}5{#/blank#}(suffer). But those{#blank#}6{#/blank#}are against the research say that changing memories{#blank#}7{#/blank#}(be) very dangerous because memories show who we are.

    {#blank#}8{#/blank#}the drug could first be used in only very serious cases, some people even fear that it would become more commonly used. Don't forget people always have the ability{#blank#}9{#/blank#}(use) science for the wrong purpose. What we should do is help people to have{#blank#}10{#/blank#}(good) control of memories.

    Recently Lindsay hasn't felt herself. She was a really good student, but her grades {#blank#}1{#/blank#} (fall) since three months ago. This is because she sometimes has trouble {#blank#}2{#/blank#} (concentrate) on her study. She also refuses {#blank#}3{#/blank#} (talk) with teachers and friends. What's worse, she feels {#blank#}4{#/blank#}(tire)all the time but has difficulty in falling asleep. Her behavior attracts her mother's attention. Her mother asks her what {#blank#}5{#/blank#} (happen)to her, but she just cries.

    As a matter of fact, Lindsay is {#blank#}6{#/blank#} (suffer) from clinical depression(临床抑郁症).What is clinical depression? It can be described as a mood which is {#blank#}7{#/blank#} low that it affects your daily life {#blank#}8{#/blank#} (serious).The first signs of it in teens are {#blank#}9{#/blank#} (poor) school  reports  than before, learning difficulties and staying away from  classmates and teachers. {#blank#}10{#/blank#} you have these signs, don't worry. It is not so difficult to deal with clinical depression. There are many effective ways, such as medicine, small talk, more exercise and a balanced diet.

Digital devices(设备) have become common in our lives. Today, kids often type with a keyboard instead {#blank#}1{#/blank#}writing by hand. But a recent study shows that you can learn{#blank#}2{#/blank#}(well), and possibly remember more, by handwriting your notes.

"Some schools have become{#blank#}3{#/blank#}(complete) digital," noted Audrey, who{#blank#}4{#/blank#}(lead) the study. She measured what's happening in the brain to better understand learning and behaviors. Her study found that{#blank#}5{#/blank#}(use) a pen or pencil to write notes involves more of the brain than typing on a keyboard. This is because writing needs more complex movements,{#blank#}6{#/blank#} makes more areas of our brain activate.

Think about it: you move your hands{#blank#}7{#/blank#}same way to type each letter on a keyboard. That's different from when we write. Our brain needs{#blank#}8{#/blank#}(consider) the shape of each letter. And we must control our hands to shape different letters with a pen or pencil, all of which uses and connects more areas of the brain.

So learning only by typing could be{#blank#}9{#/blank#}(harm). However, the human brain connects with the world in as many{#blank#}10{#/blank#}(way) as possible. That's why it's important to learn to write by hand and to type with a keyboard in the meanwhile.
