According to a recent survey,violence did exist in schools. Students {#blank#}1{#/blank#} (show) their fear and parents and teachers also expressed their great concern about it. {#blank#}2{#/blank#} (expert) hope the whole society will pay more attention to the mental health of adolescents.

    Nowadays, school violence is {#blank#}3{#/blank#} hot issue. I think this is a phenomenon（现象）, {#blank#}4{#/blank#} calls for our great concern.We should try every effort {#blank#}5{#/blank#} (prevent) violence happening at school for more and more students would drop out of school if their personal {#blank#}6{#/blank#} (safe) could not be guaranteed.In fact,violence can be learned.Children learn violent behavior from adults or from {#blank#}7{#/blank#} they see on television or on the Internet.

    If I meet with school violence,I will not answer violence {#blank#}8{#/blank#} violence, for it will result in {#blank#}9{#/blank#} (much、fighting.I will tell my teachers or parents about it.I think they will help me deal with it well and they will protect me from the bad guys.

    All in all, every student should behave {#blank#}10{#/blank#} (he) and keep away from violence.

    A best friend is someone to {#blank#}1{#/blank#} you can tell everything, even your most {#blank#}2{#/blank#} (person) feelings and thoughts. Anne Frank treated her diary {#blank#}3{#/blank#} her best friend. The German Nazis were in search of Anne and her family. The family had to{#blank#}4{#/blank#} away from the chase. They didn't dare to go out even in the evenings. They had to stay indoors day and night. Not {#blank#}5{#/blank#} (be) able to go out for such a long time, Anne missed the beauty of nature so much that she grew {#blank#}6{#/blank#} about everything to do with it. She stayed up {#blank#}7{#/blank#} eleven thirty one evening on {#blank#}8{#/blank#} just to see the moonlight. She said, “This is the first time I {#blank#}9{#/blank#} (see) the moonlight since I came here.”

{#blank#}10{#/blank#} (fortunate), the family were discovered at last and taken away from the hiding place.

    Several days ago, a letter attracted a lot of attention on the Internet. It was written to NASA by 9-year-old Jack Davis {#blank#}1{#/blank#}(ask) to be considered for a job working with astronauts. He wrote to apply {#blank#}2{#/blank#} a planetary protection officer position at NASA. Despite his young age, he thought he would be fit for the job {#blank#}3{#/blank#} (perfect).

    With a pencil, he wrote: “I may be nine, but I think I would be {#blank#}4{#/blank#} good fit. My sister says I am an alien. Also, I.{#blank#}5{#/blank#} (see) all the space and alien movies in the past years.” Jack ended the letter stating the other {#blank#}6{#/blank#} (factor) that would make him perfect for the position, such as his great video game skills and his youth,{#blank#}7{#/blank#} would make it easy to learn to think like an alien. He then signed the letter, “Jack, Guardian of the Galaxy.”

    The position of planetary protection officer is well-paid every year. The job, however, is more about science and biology and {#blank#}8{#/blank#} (little) about fighting aliens. The officer must make sure that no new species or plants {#blank#}9{#/blank#} (bring) to other planets, and doesn't return from trips to space with anything that might harm Earth. The recent announcement of the position created in the 1960s has caused a lot of {#blank#}10{#/blank#} (excite) in the public, according to a NASA's statement.

    Before the invention of the postage stamp, it was difficult to send a letter to another country. The sender paid for the letter {#blank#}1{#/blank#} (travel) in his or her own country. Then the person in the other country paid for that part of the trip.{#blank#}2{#/blank#} a letter crossed several countries, the problem was {#blank#}3{#/blank#} (bad).

    Rowland Hill, a British teacher, had the idea of a postage stamp with glue on the back. The British post office made the first stamps {#blank#}4{#/blank#} 1840.They were the Penny Black and the Twopence Blue. A person {#blank#}5{#/blank#} (buy) a stamp and stuck it on a letter. The post office delivered {#blank#}6{#/blank#} letter. When people received letters, they didn't have to pay anything. The letters were prepaid.

    Postage stamps became popular in Great Britain {#blank#}7{#/blank#} (immediate).Other countries started making {#blank#}8{#/blank#} (they) own postage stamps very quickly. Today, post offices in every country sell beautiful stamps.{#blank#}9{#/blank#} (collect) stamps is one of the most popular {#blank#}10{#/blank#} (hobby) in the world, and every stamp collector knows about the Penny Black and the Twopence Blue.

    Chinese high-speed railways are a very {#blank#}1{#/blank#} (comfort) way to travel. They are clean, quiet and efficient. China has led other developing countries and even some developed ones in this field since the first high-speed train {#blank#}2{#/blank#} (come) into use in 2008.

    The stations are {#blank#}3{#/blank#} (main) built outside the town center, but local transport has been lengthened {#blank#}4{#/blank#} (connect) the high-speed network. The facilities on the train are new and the staff are well trained. Even the second class {#blank#}5{#/blank#} (chair) provide plenty of space. The passages are so wide {#blank#}6{#/blank#} you can move without disturbing anyone. You can use your mobile phone, access {#blank#}7{#/blank#} Internet or work on your laptop. There is also a restaurant car, though the kinds of food {#blank#}8{#/blank#} (be) limited. The toilets arc large, clean and user-friendly too. The train almost doesn't rock. Even when the train brakes, you can hardly feel it shake.

    What's more, with a faster check-in, the high-speed train are also {#blank#}9{#/blank#} (little) affected by weather than planes. Seldom are {#blank#}10{#/blank#} delayed or cancelled for weather condition. Therefore, they have become the first choice for many passengers.
