Years ago, if a teenager had some problems in his life, he might write them in his diary. Now a teenager w{#blank#}1{#/blank#} the same problems might get on the Internet and write them in his blog. In many ways, a diary and a blog are almost the same. So, what makes a blog d{#blank#}2{#/blank#} from a diary?

    The biggest difference is that a blog is much more public t{#blank#}3{#/blank#} a diary. Usually, a teenager likes hiding his diary book and treats it as one full of s{#blank#}4{#/blank#}. Both diaries and blogs tell what happened to the writer that day.

    A blog has both good and bad points (特点). The biggest problem is that anyone can read what you write in your blog. If you are not satisfied with a friend during school and write something bad about him in your diary, he will never know it. H{#blank#}5{#/blank#}, if you do this on the Internet, that friend may read your blog and get a{#blank#}6{#/blank#}. So we have to be careful of what we write.

    A blog has good points, of course. People choose to write in blogs, they know that their friends will read what they write. If you are f{#blank#}7{#/blank#} sad one day and write in your diary, no one will know about it. If you write the same words in your blog, your friends may quickly w{#blank#}8{#/blank#} back to comfort you or offer you help. Blogs help people stay in close contact and let them know what their friends are doing.

T{#blank#}9{#/blank#} it's a good way to write blogs about everyday life, I still p{#blank#}10{#/blank#} my old diary.

    One day, a lobster(龙虾) met a hermit crab(寄居蟹)in the deep sea. They stopped {#blank#}1{#/blank#} (swim) and began to have a talk with each other.

    The lobster {#blank#}2{#/blank#} (take) off his hard shell and showed his lovely and soft body. When the hermit crab saw the lobster take off the shell, {#blank#}3{#/blank#}felt surprised. He shouted at the lobster and wanted to stop the lobster.

    "Hey!" said the crab. “{#blank#}4{#/blank#} are you talking off your shell? The shell is {#blank#}5{#/blank#} (use) and it can protect you. Now you take off your shell. Big fish may eat you. You may also knock against a rock. Don't be silly. Please put {#blank#}6{#/blank#} your shell again. Or you will have to {#blank#}7{#/blank#} (payment) a heavy price for what you did."

    “{#blank#}8{#/blank#} (thank) for your reminding, hermit crab! But we take off our shells in order {#blank#}9{#/blank#} (grow) better. {#blank#}10{#/blank#}we are afraid to take off our shells, then we can't move forward in life," answered the lobster.

    The hermit crab thought it over and understood what the lobster said.

    Have you ever thought of living on Mars? Our Earth is becoming more and more c{#blank#}1{#/blank#}. And at the same time there's terrible p{#blank#}2{#/blank#} here. If we move to Mars, things will probably change. However, it may be d{#blank#}3{#/blank#} for people to have a conversation there, because sound doesn't travel very f{#blank#}4{#/blank#} on Mars. The low pressure(气压) makes it so. For example, as{#blank#}5{#/blank#} by a human scream on Earth can travel a little over a kilometre. But on Mars, the sound from that same scream will only move 15 metres at m{#blank#}6{#/blank#}. Besides, the atmosphere on Mars is also much t{#blank#}7{#/blank#} than that on Earth. On Earth, our atmosphere is about 3 km t{#blank#}8{#/blank#}, while it is very thin on Mars. Also Earth has a much higher t{#blank#}9{#/blank#} than Mars. while it is very thin on Marsso, are you r{#blank#}10{#/blank#} to go to Mars?
