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.

    Happiness means different things to different people. For Mary, who has {#blank#}1{#/blank#} severe sleeping problem, happiness is as simple as having a good night's sleep.

    Bed was once a place {#blank#}2{#/blank#} Mary went to rest after a long, hard day. {#blank#}3{#/blank#}, she has not had a full night's sleep in almost six months. Her doctor said that{#blank#}4{#/blank#}(count) sheep might help her fall asleep. She tried this, but soon got tired of it after it failed to work. She finds the nights without sleep almost {#blank#}5{#/blank#}(bear) . She is always sleepy and lacks energy during the day.

    Mary is not alone. Studies show that more than one in three people worldwide struggle with getting enough sleep. It often takes on different {#blank#}6{#/blank#}(form) : some people can get to sleep, but wake up much too early; some get a full night's sleep, but are {#blank#}7{#/blank#}(disappoint)  to find that they still feel tired when they wake up; others, like Mary, find {#blank#}8{#/blank#} difficult to fall asleep in the first place.

    Specialists say that people should not worry too much about this problem. In most cases, a lack of sleep {#blank#}9{#/blank#}(cause) by anxiety and pressure. It is important to keep yourself {#blank#}10{#/blank#} good spirits and to be positive. 

    In my family, there {#blank#}1{#/blank#}(be) three people. My father is a {#blank#}2{#/blank#} (farm) and goes to work in the field every day. He isn't good at {#blank#}3{#/blank#} (talk) but he gets on well with other people. My mother is very kind and is {#blank#}4{#/blank#} (friend) to everybody. So when I have {#blank#}5{#/blank#} problem I will turn{#blank#}6{#/blank#} her for help. My friends say I am clever, because when the teacher asks {#blank#}7{#/blank#} (we) very difficult questions, I can come up with the answers {#blank#}8{#/blank#} (quick). But my father thinks I am not patient. He says once I have difficulty in {#blank#}9{#/blank#} (solve) problems, I will {#blank#}10{#/blank#} (easy) give up. This is what I need to improve in the future.

Dear Sir or Madam,

    I have{#blank#}1{#/blank#}(recent) read about your organization in the local newspaper. In my opinion, you are doing a great job and {#blank#}2{#/blank#}（give）a great opportunity to people with a desire to help people living in absolute poverty.

    I have just graduated from the Pedagogical University and got{#blank#}3{#/blank#}bachelor's degree（学士学位）. My aunt left me fifteen thousand dollars in her will(遗嘱) and in memory {#blank#}4{#/blank#}her I have decided to share my knowledge and volunteer to teach English to people{#blank#}5{#/blank#}can't afford it.

    Moreover I also speak French well and I once{#blank#}6{#/blank#}(teach) both English and French in school.

    It{#blank#}7{#/blank#}(mention) in the article of your newspaper that the work of Cultural Expeditions covers countries in Africa. If it is{#blank#}8{#/blank#}(possibility) I would like to work in Nigeria for one year from September 15th.

    I am sending my CV(个人简历) where you can find all the information about my {#blank#}9{#/blank#}(educate) and references.

    If you have any{#blank#}10{#/blank#}(question) you can get in touch with me by email or phone number written in my CV.

    I am looking forward to your reply.

Yours sincerely,

Mary

    Traditional Chinese culture is beginning to capture the attention of the world. Kung fu,{#blank#}1{#/blank#} (especial), has had a great effect {#blank#}2{#/blank#}the millions of people who first learned about China through it. From that, they may come to China and learn about some other {#blank#}3{#/blank#}(aspect) of this culture. Other Asian nations have long known about the {#blank#}4{#/blank#}(great) of ancient Chinese culture. Their own cultures are {#blank#}5{#/blank#}mix of native ones and those Chinese characteristics. Korea and Japan long ago adopted Confucianism (孔子学说）, something that continues today even as it {#blank#}6{#/blank#}(challenge) by pop culture . This strength comes from the ideas {#blank#}7{#/blank#} (give) in the Four Books of Confucianism, which built upon the ideas of an even {#blank#}8{#/blank#}(much) ancient period codified (编纂) in the Five Classics . From them, the West learns {#blank#}9{#/blank#} is uniquely Chinese, for example, feng shui. So far China has taken steps {#blank#}10{#/blank#}(further) this spread of its culture by establishing Chinese Cultural Centers in such places as the United States and Europe.

    China successfully landed the Chang'e 4 lunar probe(月球探测器)on the far side of the moon on January 3,2019, becoming the only country in history{#blank#}1{#/blank#}(touch) the lunar surface unseen by those on Earth. The far side of the moon has been seen and mapped{#blank#}2{#/blank#}(previous) by astronauts of the Apollo missions. But it is the first time that the moon's far side{#blank#}3{#/blank#}(set) foot on by any spacecraft, and the successful landing of Chang'e 4 is seen as a major milestone in space {#blank#}4{#/blank#}(explore).

    The Chang'e 4 spacecraft consists{#blank#}5{#/blank#}two parts:a lander and a rover(巡视器). Representing China's{#blank#}6{#/blank#}(new) step in the lunar probe project of all time, it landed at 10:26 am Beijing time. Then it sent back a photo of the landing place.{#blank#}7{#/blank#}(shoot) through cameras on the probe's lander, the photo marks the world's first image taken on the surface of the far side of the moon. One of the photos published by the China National Space Administration shows the place{#blank#}8{#/blank#}Chang'e 4's rover-named Yutu 2~will be heading hours later for{#blank#}9{#/blank#}purpose of conducting further research. The name Chang'e has its roots in the Chinese goddess of the moon. In the ancient tale, Chang'e{#blank#}10{#/blank#}(fly) to the heavens and landed on the moon as her final resting place.
