I went to the doctor's yesterday {#blank#}1{#/blank#} I had a bad cold. I have {#blank#}2{#/blank#} for three days, so I had a sore throat. When I got there,m there were many people {#blank#}3{#/blank#}  inline. I had to join the line at the end. But the man who was in front of me was{#blank#}4{#/blank#}  there. The smoke made me sick. I wanted to stop him but I was afraid he would get{#blank#}5{#/blank#} . But I really couldn't stand it. So I told him {#blank#}6{#/blank#} , “Would you mind smoking outside?” After hearing what I said, the man threw the{#blank#}7{#/blank#}  on the ground and said to me, “Sorry.”I thought it was bad to do so, but I said {#blank#}8{#/blank#} and picked up the cigarette. Seeing what I was doing, the {#blank#}9{#/blank#}  face turned red and felt very sorry about {#blank#}10{#/blank#} he did. He turned to me and said, “You are a good girl. I won't do that again.”

People often talk on their mobile phones when they are driving. But talking or sending messages over a mobile phone can be as{#blank#}1{#/blank#} as drunk driving. They can't pay more attention to the road safety any more. Because of this, about 330,000 people are hurt and more than 2,000 people {#blank#}2{#/blank#} every year.
Now, an American company invented a key by using Bluetooth technology {#blank#}3{#/blank#} help people drive safely. With the key, a driver can't talk or send messages when driving a car.
With Bluetooth technology, when the driver is driving, the phone will{#blank#}4{#/blank#} all incoming calls and messages by itself with “I am driving now. I will call you later.” The only calls allowed out are to emergency services. When the driver {#blank#}5{#/blank#} the car, he then can use the phone. This is all about saving lives and safer driving.

    The champions of the Earth Awards (地球卫士奖) is the United Nations' highest environmental honor. On Dec 5th, 2017, it {#blank#}1{#/blank#} to China's Saihanba.

    Saihanba is a vast forest{#blank#}2{#/blank#} in Chengde, Hebei. In Mongolian, its name means “beautiful highland”, and rightly so: across the area{#blank#}3{#/blank#} forests and grasslands are around crystal-clear lakes.

    Around the 10th century, Saihanba became a{#blank#}4{#/blank#} hunting ground. During the Qing Dynasty (1644-1911), Emperor Kangxi liked Saihanba so much and he once killed 318 rabbits in a single day.

    In 1860, because of a shortage of money, the land {#blank#}5{#/blank#}to the public. In the following years, logging (砍伐) and wildfires destroyed the forest and grassland. By the 1950s, Saihanba had become a barren (荒芜的) land.

    Hard work and efforts{#blank#}6{#/blank#} a national forest in Saihanba started in the 1960s. In 1961, a group of six scientists traveled through Saihanba and studied the {#blank#}7{#/blank#} of growing trees there.

    They finally found one tree standing alone in the vast land, which {#blank#}8{#/blank#}encouraged them. If one tree could survive there, so could millions of others.

    About 56 years later, after overcoming the countless difficulties of planting trees in a very cold place, the barren land is now a vast forest. Today, Saihanba is known as a natural shield (防护){#blank#}9{#/blank#} sandstorms. It is very important for Beijing's water and air{#blank#}10{#/blank#}

    We all need exercise. Exercise uses up food that we eat and keeps the body full {#blank#}1{#/blank#} energy(能量). Exercise makes your heart and muscles(肌肉) strong. Exercise {#blank#}2{#/blank#} makes you feel relaxed. If you exercise several times a week, you will stay happy and {#blank#}3{#/blank#}. There are many {#blank#}4{#/blank#} to exercise. You can walk, run or swim.

    However, most people cannot do this. It is too far from their homes to their offices. They have no choice {#blank#}5{#/blank#} to drive to work. First, these people don't have a chance to exercise because they are sitting in their cars for two to four hours each day. Second,  driving is challenging(具有挑战性的), {#blank#}6{#/blank#}in rush hours, and needs too much attention.  It makes a person tired out. When these people arrive home after work, they don't want to take exercise.

    Some western countries, such as the United States, have problems with {#blank#}7{#/blank#}. Many people don't have enough exercise. They have to work from morning till night, so they don't have time {#blank#}8{#/blank#} exercise.

    Today, many people in the West are fat, which causes health problems. Doctors say exercise can help people both lose {#blank#}9{#/blank#} and improve their health. So many people are trying to get more exercise. But it takes time to change, and when people don't see a {#blank#}10{#/blank#} right away, they will lose heart and stop exercising.
