Zoos are places {#blank#}1{#/blank#} animals are kept. There are some reasons {#blank#}2{#/blank#} keeping animals in zoos.

    Firstly, zoos are entertaining and interesting places of children. Most children like to see animals in zoos. Zoos also offer people {#blank#}3{#/blank#} (live) in big cities a chance of getting close to nature.

    Secondly, it is easier for scientists to research animals' lives when they are kept in zoos than they are in forests. Scientists can study animals' {#blank#}4{#/blank#} (relate), their life cycles, or their habits to learn how to breed animals, {#blank#}5{#/blank#} can reduce animal {#blank#}6{#/blank#} (extinct).

    Furthermore, the risk of dying out of some {#blank#}7{#/blank#} (endanger) animals is reduced because they are kept in safety.

    {#blank#}8{#/blank#}, zoos also cause some problems for animals, such as restrictions on their freedom. They also lose their “wild” character. For example, tigers might lose their {#blank#}9{#/blank#} (hunt) skills. Besides, zoos cost a lot of money for land, animals' food and labors. This may charge {#blank#}10{#/blank#} (expense) for people who want to visit zoos.

    Cambridge University is one of the {#blank#}1{#/blank#}(old) universities in the world, and one of the largest in the United Kingdom. It is famous {#blank#}2{#/blank#} outstanding academic achievements and the high quality of research undertaken in a wide range of science and art subjects. The university pioneers work in the {#blank#}3{#/blank#} (understand) of diseases, the creation of new materials, advances in telecommunications and the research into the origins of the universe. It trains doctors, veto, architects, engineers and teachers. At all levels about half of the students at Cambridge study arts and humanities, many of {#blank#}4{#/blank#} have gone on to become outstanding figures in the arts, print and broadcast {#blank#}5{#/blank#}(medium). The university's achievements in sconces can be measured by the sixty or more Nobel Prizes {#blank#}6{#/blank#}(award) to its members over the years.

    As Cambridge approached {#blank#}7{#/blank#}(it) eight hundredth anniversary in 2009, it was looking to the future. The modern university is an international center of teaching and research in {#blank#}8{#/blank#} vast range of subjects. It continues to change in response to the challenges it faces. The 1990s {#blank#}9{#/blank#}(see) a major expansion of the university accommodation for teaching and research. There are many major new buildings either underway {#blank#}10{#/blank#} already completed, including the Law Faculty Building and the Judge Institute of Management Studies.

    {#blank#}1{#/blank#}(keep) a diary in English is one of the effective ways to improve our English writing abilities.

    Compared with other forms of writing, it is shorter and takes{#blank#}2{#/blank#}(little) time. It can help us to develop the habit of thinking in English. If we keep doing this，{#blank#}3{#/blank#} (gradual)we'll learn how to express ourselves in English. In keeping a diary in English，we will certainly meet many difficulties. First, it often happens that we have difficulty{#blank#}4{#/blank#}(find)proper words and phrases to give expression to our mind.{#blank#}5{#/blank#} (two), there are so many idioms(成语)in Chinese{#blank#}6{#/blank#}it is extremely hard for us to put them into English properly.

    In my opinion，my{#blank#}7{#/blank#}(suggest)is that we should always have a notebook and a Chinese-English  dictionary  within  easy reach. Whenever something{#blank#}8{#/blank#}(beat)us，we can first put it down in our notebook and then refer {#blank#}9{#/blank#} our dictionary. We can also turn to our English teacher for help，if necessary. In short，I believe that it is of great use to keep{#blank#}10{#/blank#}diary in English for the development of our writing skills.

    There is a woman {#blank#}1{#/blank#}（name）Daisy who has devoted all her life to {#blank#}2{#/blank#}（attend）to the homeless children. It's generally recognized that what she has done for children {#blank#}3{#/blank#}（deserve）to be respected by everyone. {#blank#}4{#/blank#}（personal）speaking, her selfless behavior sets a good example to us.

    There was a time when I came across Daisy who {#blank#}5{#/blank#}（invite）to deliver a speech, during which she indicated, “{#blank#}6{#/blank#}（take）care of homeless children is just {#blank#}7{#/blank#} ordinary job, but it doesn't mean that you can look down {#blank#}8{#/blank#}it. Every job is equal. We can't say which one is {#blank#}9{#/blank#}（good ）.” She also said, “Once you set out to do something, you ought to carry on with it to the end, {#blank#}10{#/blank#} you will gain nothing in the end.”

    The man who is going to fix our roof must be {#blank#}1{#/blank#}(honest) person my husband and I have ever met.

    My husband knew the back roof of the porch was fine and wanted {#blank#}2{#/blank#}(see) what this roofer would say when he gave his estimate. He told my husband that the back roof was just fine and then gave the estimate for the rest of the roof:$2,400.

    He called last night to tell us he could do the roof on Monday but {#blank#}3{#/blank#}(tell) us he had measured the roof {#blank#}4{#/blank#}(correct) by forgetting to add on the front part of the roof.{#blank#}5{#/blank#} instead of giving us a new estimate, he told us he {#blank#}6{#/blank#}(go) to do the roof for what he quoted us.

    My husband asked him what the correct estimate would {#blank#}7{#/blank#}(be).He said,"$3,000."Well, that's what I had thought it would be so that's {#blank#}8{#/blank#} I set aside. My husband was simply {#blank#}9{#/blank#}(amaze) at this roofer.

    The roofer doesn't know our decision that he'll get the $3,000.He's honest and is planning to be responsible for the mistake. My boss was kind to me when I made some {#blank#}10{#/blank#}(mistake) in the past and now I get a chance to pass this on to others.
