When I was a university student, I {#blank#}1{#/blank#}(attract) by the Chinese. So I got a job as a teacher in Wuhan three years ago.{#blank#}2{#/blank#} (think) back, I realize it was the students I met in the first year and Chinese university life in general {#blank#}3{#/blank#}gave me the deepest impression.

    During my school days, I would rarely give up my spare time to any activity {#blank#}4{#/blank#}(connect) with study. Unless exams were approaching, my weekends were devoted to having fun or perhaps a part-time job. My Chinese students,{#blank#}5{#/blank#} the other hand, seemed to spend their entire waking hours studying. I understand that competition in Chinese universities is extremely fierce. Nonetheless, their energy and motivation put {#blank#}6{#/blank#}(I) to shame.

    My first year in China was also my first year as a teacher. It was both challenging {#blank#}7{#/blank#}rewarding. One thing I know for certain is that my year in Wuhan changed me for the {#blank#}8{#/blank#}(good). Thanks to the politeness and {#blank#}9{#/blank#}(warm) of Chinese students, I overcame my fear of speaking in public and became more self-confident. Most {#blank#}10{#/blank#}(important), I met dozens of nice people and made many excellent friends.

    If you go out to the fields at night in spring or summer, you can hear frogs singing{#blank#}1{#/blank#}(joy) here and there. It seems as if they were performing a field symphony（交响乐）.

    The frog is a good and useful creature that benefits human beings. They can catch fast-moving insects. Each frog eats a large number of pests that are {#blank#}2{#/blank#}(harm) to crops. This little creature is regarded {#blank#}3{#/blank#}“the natural enemy of pests”.

    {#blank#}4{#/blank#} now frogs are getting fewer and fewer. This is{#blank#}5{#/blank#}they are killed and put on the table as a delicious dish by their chief enemy, human beings. It is a shameless and cruel act, isn't it? Another reason responsible for the rapid reduction of frogs is {#blank#}6{#/blank#}farmers use insecticides (杀虫剂) to kill pests and frogs get {#blank#}7{#/blank#}(kill)as a result of drinking poisoned water or eating poison-killed insects.

    Something must be done without delay {#blank#}8{#/blank#}(save) frogs. If we don't punish those {#blank#}9{#/blank#}sell and kill frogs to make money, then one day all of us {#blank#}10{#/blank#}(punish) by nature for failing to keep the balance of nature.

    Bank of China and Alibaba are the dream employers for Chinese students, according to a new survey.

    The survey of more than 55,000 students, {#blank#}1{#/blank#}(conduct) by a research firm Universum, found that {#blank#}2{#/blank#}(rough)a quarter want to work for an international company, while only 9% want to work for a start-up. Five percent want to start {#blank#}3{#/blank#}own business.

    When it comes to desirable companies, business students{#blank#}4{#/blank#}(name)Bank of China the top choice for seven years, and it shows no signs of {#blank#}5{#/blank#}(give)up its lead.

    William Wu, manager of Universum, said that banking remains{#blank#}6{#/blank#}attractive industry for young Chinese. “China's government is now emphasizing the revolution of finance industry, {#blank#}7{#/blank#}leaves the younger generation with the impression that though banking is a {#blank#}8{#/blank#}(tradition)industry, there are still a lot of development {#blank#}9{#/blank#}(opportunity),” Wu said.

    Alibaba improved six places from 2014, {#blank#}10{#/blank#}(rank)second among business students. It held a record-breaking $25 billion IPO in September.

    In Hebei Province lies a vast forest called Saihanba. This green Great Wall, {#blank#}1{#/blank#} at its peak during the Qing Dynasty covered thousands of hectares, had by the 1950s {#blank#}2{#/blank#}（virtual）disappeared. This allowed sand to blow into Beijing from the northern deserts.

    Saihanba is a combination of Chinese and Mongolian, {#blank#}3{#/blank#}（mean）“beautiful highlands". Until the Qing Dynasty, it was a royal hunting land because of its cool summer weather and beautiful surroundings. However, most of the area had turned into a desert by the end of the Qing Dynasty.

    In fact 56 years ago there was only one tree left. But without that tree, there {#blank#}4{#/blank#}（be）no miracle of Saihanba today. In the early 1960s, over 350 foresters {#blank#}5{#/blank#}（send）to this area to fight the desert. They were required {#blank#}6{#/blank#}（rebuild）the forest in Saihanba. Few people, including the foresters themselves, believed they would succeed.

Their doubt disappeared, however, when they found the 200-year-old tree, swaying alone in {#blank#}7{#/blank#} wind. If one tree could survive here, {#blank#}8{#/blank#} could millions of trees, they thought.

    After decades of hard work, three generations of the foresters have restored almost 80% of the original Saihanba forest. Recently, they were awarded the {#blank#}9{#/blank#}（high）environmental honor from the United Nations for their great {#blank#}10{#/blank#}（contribute）to creating a greener world.

    Many of the earth's plants and animals have already{#blank#}1{#/blank#}(die) out, and a hundred species become {#blank#}2{#/blank#}(endanger) every day. If nothing is done, we may find ourselves{#blank#}3{#/blank#} (lonely) on the earth.

    Wild animals live in the{#blank#}4{#/blank#} (forest) which are being destroyed by people. As{#blank#}5{#/blank#} result, the animals are {#blank#}6{#/blank#}(lose) their habitats. Without the trees, the animals are short of food. And many animals are dying out because of pollution.

    I suggest that measures should be taken {#blank#}7{#/blank#}(protect) wildlife. The government should keep people {#blank#}8{#/blank#}destroying forests and shut down the factories {#blank#}9{#/blank#} pollute rivers and air, I think more wildlife reserves should also be {#blank#}10{#/blank#}(build).
