Ask three people to look out of the same window at a busy street corner and tell you what they see. {#blank#}1{#/blank#}(chance) are that you will receive three different answers. Each person sees the same scene, but each perceives something different about {#blank#}2{#/blank#}.

    Perceiving goes on in our minds. Of {#blank#}3{#/blank#} three people who look out of the window, one may say that he sees a policeman {#blank#}4{#/blank#}(give) a motorist a ticket. Another may say that he sees rush-hour traffic jam at the intersection. The {#blank#}5{#/blank#}(three) may tell you that he sees a woman trying to cross the street with four children. Perception is the mind's {#blank#}6{#/blank#}(interpret) of what the senses — in this case our eyes — tell us.

    Many psychologists today are working to try {#blank#}7{#/blank#}(determine) just how a person experiences or perceives the world around. Using a scientific approach, these psychologists set up experiments in  {#blank#}8{#/blank#} they can control all of the factors.  {#blank#}9{#/blank#} measuring and charting the results of many experiments, they are trying to find out what makes different people perceive  {#blank#}10{#/blank#}(total) different things about the same scene.

    Charles Richard Drew {#blank#}1{#/blank#}(be) a famous African — American doctor and scientist. His work on blood banks helped save thousands of{#blank#}2{#/blank#}(life) during World War II.

    Charles Richard Drew {#blank#}3{#/blank#}(bear) in 1904 in Washington D.C. His main interest was in sports when he was young. He won many medals for {#blank#}4{#/blank#}(swim). Later, he turned to basketball and football. During college, Charles became interested in medicine. He attended Medical School at McGill University in Canada. In 1933, he received {#blank#}5{#/blank#}(he) doctor of Medicine Degree.

    As a doctor and a researcher, Charles was absorbed in research on blood transfusions（输血）. Through his experiments, he found that blood plasma（血浆）could be {#blank#}6{#/blank#}(success) used instead of whole blood. He {#blank#}7{#/blank#}(write) up the results in a published report.

    During World War II, Charles worked with the British. He helped them develop the blood bank. He organized the collection{#blank#}8{#/blank#} processing of blood plasma from different hospitals. These life-saving plasmas cured wounded people in the war. He also helped the American Red Cross develop a blood bank.

    Charles died in 1950 as {#blank#}9{#/blank#} result of a car accident. After his passing away, he received many honors. Many schools and institutions were named {#blank#}10{#/blank#} him.

A: Hi, Lily! How about {#blank#}1{#/blank#}(go) to see a film together?

B: What time?

A: This Saturday evening.

B: I'm afraid I {#blank#}2{#/blank#}(can) go with you. So you'd better go there {#blank#}3{#/blank#}yourself.

A: Why? I {#blank#}4{#/blank#}(buy) two tickets already. This film is said to be very {#blank#}5{#/blank#}(interest). I had a lot of trouble in getting these two tickets.

B: I'm really sorry but I had made an{#blank#}6{#/blank#} (appoint) already. I'm going to see my former professor Lee at university this Saturday afternoon.

A: But can't you find some other time to see{#blank#}7{#/blank#}?

B: No, I can't. He is now {#blank#}8{#/blank#} (serious) ill in hospital.

A: Your teacher will be very happy {#blank#}9{#/blank#} (see) you.

B: I'm sure he will. He used to be very kind to us students {#blank#}10{#/blank#}we were at university. How about next Saturday? I will be free the whole day.

A: OK, let's make it next Saturday.

    I have been learning English for the last five years and one of the things {#blank#}1{#/blank#} has helped me to improve is reading. I love reading and often read during my free time. First, I {#blank#}2{#/blank#} (start) reading easy things in English, like recipes (食谱) for cooking and short stories {#blank#}3{#/blank#} (write) especially for language learners. Then I moved onto longer stories and newspaper articles. {#blank#}4{#/blank#} first I found that reading was difficult because of the variety of vocabulary and the grammar, {#blank#}5{#/blank#} this soon became easier and I found that I could understand more and more of {#blank#}6{#/blank#} I was reading. I didn't worry if I didn't know all the words, as I could still understand the main ideas. Reading has helped improve my English in many ways. I'm not only {#blank#}7{#/blank#} better and quicker reader, but also my {#blank#}8{#/blank#} (spell), writing, grammar and vocabulary are all much better. I think I have improved faster {#blank#}9{#/blank#} some of my friends who have been learning at the same time as me. So, I would say that everyone who wants to learn a language {#blank#}10{#/blank#} (quick) should read.

    Everyone has dreams, but not all dreams can be realized. People give up their dreams for this or that reason. Those {#blank#}1{#/blank#} dreams become true have one thing in common, that is, they insist on {#blank#}2{#/blank#} (work) for their dreams.

    Marie Curie, a famous scientist, has set {#blank#}3{#/blank#} good example. In 1898, Marie {#blank#}4{#/blank#} (find) a new element (元素) in the pitchblende (沥青铀矿). {#blank#}5{#/blank#} (prove) her discovery, she had to show it to the world, which also became her dream. After using tons of pitchblende, Marie and her husband {#blank#}6{#/blank#} (final) saw the blue light of radium (镭). There are many other examples. Athletes who gain gold medals and students who enter key universities after {#blank#}7{#/blank#} (year) of hard work, are all dream-holders.

    The path to dreams may not be smooth and the progress may be {#blank#}8{#/blank#}(pain). But hold on to your dreams, no matter {#blank#}9{#/blank#} big or small they are. Hold on to the end, and you will find there is nothing {#blank#}10{#/blank#} (happy) than your dreams coming true.
