    “Click!” That's the sound of safety. That's the sound of survival. That's the sound of a seat belt locking in place. Seat belts save lives and that's a fact. That's why I don't drive anywhere until {#blank#}1{#/blank#}(I) is on tight. Choosing {#blank#}2{#/blank#}(wear) your seat belt is like choosing between life and death. Imagine you are driving at 100 kilometers per hour or{#blank#}3{#/blank#} (fast) when somebody ahead of you puts on his or her brakes suddenly. What may happen to you?

    Someone think that seat belts are {#blank#}4{#/blank#}(comfortable). Let's just take {#blank#}5{#/blank#} close look at your choice. You are not wearing your seat belt{#blank#}6{#/blank#} you can slide in and out of your seat easily. That sounds {#blank#}7{#/blank#}a lot of fun. But you are also more likely to die or suffer serious{#blank#}8{#/blank#}(injury).

    Wearing a seat belt does not make you completely safe. You can get killed or{#blank#}9{#/blank#}(hurt) while wearing your seat belt. But wearing them{#blank#}10{#/blank#}(prove) to be safer than without them. So why not take the safer way?

    Teenagers have long been told that being active and {#blank#}1{#/blank#}(take) part in sports is good for their health. But new research suggests that too much sport for teenagers could negatively affect their well-being just as much as too {#blank#}2{#/blank#} sport.

    The US Department of Health and Human Services suggests that young people {#blank#}3{#/blank#}(age) between 6 and 17 work{#blank#}4{#/blank#}at least 60 minutes a day, 7 hours a week. But researchers from Switzerland say their study suggests that 14 hours of physical activity a week is best for promoting good health in teenagers. However, more than 14 hours {#blank#}5{#/blank#} (appear) to be harmful to their health. To reach their findings, they had 1,245 teenagers {#blank#}6{#/blank#}(survey) in their research.

    All participants (参与者) were required to answer questions about height and weight, sports practice, sports {#blank#}7{#/blank#} (injure) and well-being. Their well-being was measured using the Word Health Organization (WHO) Well-being Index, {#blank#}8{#/blank#} provides scores between 0 and 25. Of the participants, 50.4% were male. Almost 9% of these males were overweight. The overall {#blank#}9{#/blank#}well-being score for all participants was 17.

    The researchers divided sports participants into low, average, {#blank#}10{#/blank#}, and very high. The researchers found that participation in the low and very high activity groups were more likely {#blank#}11{#/blank#} (have) well-being scores below 13, compared with participants in the average group. The researchers found that the highest well-being scores were {#blank#}12{#/blank#} a by participants who carried out around 14 hours of physical activity a week, but beyond 14 hours resulted {#blank#}13{#/blank#} lower well-being scores.

    The researchers suggest that doctors {#blank#}14{#/blank#} care for teenagers should check their level of sports practice. Teenagers {#blank#}15{#/blank#} (probable) need a supportive and closer follow-up of their health and well-being.

    No one loves me more than my parents, especially my father. My father is stout and strong, {#blank#}1{#/blank#} a serious look on his face and keen expressive eyes. At first sight you may feel him hard {#blank#}2{#/blank#} (approach). In fact he is very kind and considerate. I believe my father is a {#blank#}3{#/blank#} (gift) man. He is decisive and efficient in doing things. By his own talents and years of efforts, he {#blank#}4{#/blank#} (provide) his children with good education and a {#blank#}5{#/blank#} (relative) rich life. Besides, he lives in harmony with others and never quarrels with anyone, so people from all walks of life come to my house, from {#blank#}6{#/blank#} I've gained lots of social experiences. But at home he is a strict parent who is hard on me and has a high{#blank#}7{#/blank#} (expect) of me. I can see that my idling away time hurts him deeply, while {#blank#}8{#/blank#} I have done something great and meaningful, such as {#blank#}9{#/blank#} (write) a book, he will be more excited than me. I always remind {#blank#}10{#/blank#}(I) I must go on and on, and never shall I give up halfway.
