A proverb says, "Time is money". But in my opinion, time is even {#blank#}1{#/blank#} precious than money. Why？{#blank#}2{#/blank#} when money is spent, we can earn it back. However, when time is {#blank#}3{#/blank#}（go） , it will never return. {#blank#}4{#/blank#} is known to all that the time we can use is limited. Therefore we should make {#blank#}5{#/blank#} use of our time to study hard so as to serve our country in {#blank#}6{#/blank#} future. But it is a pity that there are a lot of people {#blank#}7{#/blank#} do not realize the value of time. They waste their precious time smoking, drinking and playing. In {#blank#}8{#/blank#} word, we should form the good habit of {#blank#}9{#/blank#} (save) time. Do not put off what can be done today {#blank#}10{#/blank#} tomorrow.

    “Why are you unwilling to accept this opportunity in space? Have you read the{#blank#}1{#/blank#}(describe) carefully?” Wang Ping asked me. “You will live in a {#blank#}2{#/blank#}(furnish) house with all modem equipment and robots will be able to clarify any problems. You are only needed to become familiar with the administration and rules for such a project. It will be an{#blank#}3{#/blank#} (enjoy) experience for you.”

    Many people need to be reminded of the job opportunities in space stations, which{#blank#}4{#/blank#} (constant) need space cooks, cleaners, teachers, stewards and stewardesses. You can be swiftly trained for your new job from using previous skills. At first people may find new surroundings difficult{#blank#}5{#/blank#}(tolerate). However, they will be able to overcome the difficulties if their families encourage them to take{#blank#}6{#/blank#} the job. There are lots of advantages{#blank#}7{#/blank#}come from a period of time in space. But for health reasons only one stay of three years{#blank#}8{#/blank#}(allow), because{#blank#}9{#/blank#}link between illness and length of stay may be strong. It is a little disappointing,{#blank#}10{#/blank#}the rules cannot be changed for anyone.

    In a recent survey, 19 percent of teenagers said they had posted a comment online that they later regretted. The problem is that once something {#blank#}1{#/blank#}(put) on the Internet, it can be difficult to remove. Even if you're able to do so, someone else {#blank#}2{#/blank#}(probable)has already taken a picture your post. In addition, the content{#blank#}3{#/blank#}(delete)from a Webpage can often be recovered.

    Posting negative comments or images online is certainly best avoided, {#blank#}4{#/blank#} that's not the only thing you should consider when it comes to your online behavior. Experts say it's also important for young people {#blank#}5{#/blank#} (earn) a positive Internet reputation. You can do this by sharing positive content about the things you're most interested{#blank#}6{#/blank#}. This way, if someone {#blank#}7{#/blank#}(run)a search on you, the results will show them the content you most want them to see.

    Managing an online reputation can be {#blank#}8{#/blank#} (challenge). Remember that privacy settings can be very helpful for this, so use {#blank#}9{#/blank#}(they)if they're available. But most importantly, be careful about{#blank#}10{#/blank#} you share-your future may depend on it.

If we go to{#blank#}8{#/blank#}（differ）provinces, we may not be able {#blank#}9{#/blank#}（communicate）with the local people orally. However, we can understand each other in writing. The written language can be further divided{#blank#}10{#/blank#}different forms, like simplified Chinese and traditional Chinese.
