I'm not sure {#blank#}1{#/blank#} is more frightened, me or the female gorilla(大猩猩）that suddenly appears out of nowhere. I'm walking on a path in the forest in the Central African Republic. Unexpectedly, I'm face-to-face with the gorilla, who begins screaming at {#blank#}2{#/blank#} top of her lungs. That makes her baby scream, and then a 400-pound male appears. He screams the {#blank#}3{#/blank#}(loud)of all. The noise shakes the trees as the male beats his chest and charges toward me. I quickly lower myself, ducking my head to avoid {#blank#}4{#/blank#}(look) directly into his eyes so he doesn't feel{#blank#}5{#/blank#}(challenge).

My name is Mireya Mayor. I'm a {#blank#}6{#/blank#}(science)who studies animals such as apes and monkeys. I was searching {#blank#}7{#/blank#} these three western lowland gorillas I'd been observing. No one had seen them for hours, and my colleagues and I were worried.

    When the gorillas and I frightened each other, I was just glad to find {#blank#}8{#/blank#}(they) alive. True to a gorilla's unaggressive nature, the huge animal {#blank#}9{#/blank#}(mean)me no real harm. He was just saying: "I'm king of this forest, and here is your reminder!" Once his message was delivered, he allowed me {#blank#}10{#/blank#} (stay)and watch.

    Nearly all of us have dreamed about winning the big prize in a lottery(彩票). We dream about {#blank#}1{#/blank#} we would do with the money, but we seldom stop to think about how the money would change us.

    For most of us, our way of life is {#blank#}2{#/blank#} (close) connected with our social economy. The different parts of {#blank#}3{#/blank#} lives fit together like a jigsaw(拼板) — work, home, friends, hobbies and sports make up our world.  A sudden fortune would change it all and break the jigsaw. For example, some people like the idea {#blank#}4{#/blank#} not having to work, but winners have found that without work there is no reason to get up in the morning. It seems great {#blank#}5{#/blank#} (move) to a bigger house in a wealthy area, {#blank#}6{#/blank#} if you do that, you leave old friends behind.

    Usually, winners {#blank#}7{#/blank#} (advise) not to make their addresses and phone numbers known, but begging letters still arrive. {#blank#}8{#/blank#} they are not careful, most of their money will be spent {#blank#}9{#/blank#} the {#blank#}10{#/blank#} (protect) of their possessions(财产).

    First, reading books {#blank#}1{#/blank#}(be) fun. You can always keep yourself {#blank#}2{#/blank#}(interest) and it can help you have an enjoyable time if you like reading. This is especially useful when the weather is bad. It is a {#blank#}3{#/blank#}(relax) hobby too.

    Next，you can read a book anywhere：in a car，in a waiting room, on a plane, in bed—even in the bath.{#blank#}4{#/blank#} you need is a book! Reading is a convenient hobby as it is easy to stop and then start again.

    Another good reason for reading books is {#blank#}5{#/blank#} it is useful. If you read as a hobby，you {#blank#}6{#/blank#}(get) better and better at it. This means that you will read faster and will become {#blank#}7{#/blank#}(good) at understanding what you read. As your reading improves, you will probably find your school work becomes much easier. Many school subjects depend {#blank#}8{#/blank#} good reading and, as you read you learn more and more.

    Good readers are most likely to be good {#blank#}9{#/blank#}(write), too. They are usually good at{#blank#}10{#/blank#}(spell) as well, and have more things to write about. Reading books is really a wonderful hobby.

    Robot teachers are now very popular with pupils in some primary schools in South Korea. Compared with human teachers, the robot teachers are {#blank#}1{#/blank#} (patient). They never get angry and are always kind to the students. That's {#blank#}2{#/blank#} the children can always get on well with their robot teachers.

    English-teaching robots {#blank#}3{#/blank#} (send) to three primary schools for eight weeks last December. {#blank#}4{#/blank#} (equip) with a microphone and video camera, the robots teach students as teachers. Researchers found that the English-teaching robots helped raise students' interests in the language and build up their {#blank#}5{#/blank#} (confident). More and more students came to like studying and they got better grades in exams. Meanwhile, other robot teachers, {#blank#}6{#/blank#} can teach math, science and art, have also been developed.

    Many people think these robot teachers should be used {#blank#}7{#/blank#} faraway village schools so that the children there can also receive a good education. {#blank#}8{#/blank#} (give) rural school children more learning chances, the South Korean government has expressed great interest in {#blank#}9{#/blank#} (develop) these robots. No doubt there will be more and more robot teachers working with students. Perhaps they will {#blank#}10{#/blank#} (complete) replace human teachers one day in the future. Who knows?

    With the {#blank#}1{#/blank#}(develop) of industry, air pollution is getting more and more serious. In Beijing, many people suffer different kinds of illnesses because {#blank#}2{#/blank#} air pollution.

    Air pollution is caused by the following {#blank#}3{#/blank#} (reason): about half of the problem is caused by vehicles. There are more and more cars, buses on the roads, and they give off {#blank#}4{#/blank#} (harm) gases.25% of air pollution is caused by factories. Another factor is the smokers. Smoking not only does harm to their health {#blank#}5{#/blank#}to others. {#blank#}6{#/blank#} (beside) these, about 10% of air pollution is caused by other reasons.

    We should take some measures to fight {#blank#}7{#/blank#} pollution. New fuel can be used to take {#blank#}8{#/blank#} place of gas. We can plant more trees. If everybody realizes the {#blank#}9{#/blank#} (important) of the environment and does something to stop pollution, the problem will {#blank#}10{#/blank#} (solve).
