As is known to all, we live in a world of germs（细菌）. It is impossible to avoid exposure. Genetic makeups may give some people {#blank#}1{#/blank#} advantage over others. However, it does not stop people {#blank#}2{#/blank#}(become) sick.

    All of us have been a victim of an {#blank#}3{#/blank#}(ill) at some point in our lives. Moreover, it is likely that we {#blank#}4{#/blank#}(get) sick again in the future. Our best chances of avoiding sickness {#blank#}5{#/blank#}(be) by exercising and employing good {#blank#}6{#/blank#}(habit).

    While good hygiene and exercise serve as obvious advice to most people, eating healthily is not always obvious. If you cannot define ＂healthy＂, then your immune system will be happy {#blank#}7{#/blank#}(tell) you. The immune system is the foundation of our health. It works for us every day to keep us well. Ask yourself: ＂Are you making its job easier {#blank#}8{#/blank#} harder?＂

    Like any system, the immune system is no {#blank#}9{#/blank#}(difference). It has a tolerance too. If you eat unhealthily, your immune system will make you aware of it.

    Take a step {#blank#}10{#/blank#} the right direction by including some healthy food in your diet.

    Most of the clubs work the same way. Members read the same book at the same time. Then they meet to talk about the book. Members may be friends or people{#blank#}3{#/blank#} live near each other. Some Americans belong to reading groups on{#blank#}4{#/blank#}Internet. These groups include people around the world who communicate about books they read. They send electronic mails instead of gathering{#blank#}5{#/blank#} (discuss) books.

Other groups may{#blank#}8{#/blank#} (name) for an important person in the work of the writer,{#blank#}9{#/blank#} a Sherlock Holmes Club.

    Nowadays, in my spare time, I prefer to go outdoors and spend my time in some different places and with some different people.

    The first reason {#blank#}1{#/blank#} I do outdoor activities is that I have spent too much time indoors. Most of the time I just sit in the classroom, listening {#blank#}2{#/blank#} the teachers and doing my homework. The indoor activities are too {#blank#}3{#/blank#}(limit). The second reason is that fresh air, sunlight and enough physical exercise {#blank#}4{#/blank#}(need) for a healthy body. So when I am free, I should go out. And the {#blank#}5{#/blank#}(three) one is that I want to have more {#blank#}6{#/blank#}(experience) in my life. When you go out, far away from your daily life, you will meet a lot of people who are quite different from you. It will give you a lot of {#blank#}7{#/blank#}(beauty) moments.

    {#blank#}8{#/blank#}(do) outdoor activities, however, will take a lot of money and energy. So if you have not prepared enough, having some amusement indoors is also {#blank#}9{#/blank#} good choice. It may be much cheaper and easier {#blank#}10{#/blank#}(carry) out. Reading some books and enjoying music are also very good.

    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.
