    In many western schools, sports day is a big event. Children take part in competitive (竞争性的)sports and try to break school records and take the first place.

    Sports days, or sports meetings, are usually held in the warmer seasons, either at the beginning or the end of the school year. They are also called field days. Primary school sports days are fun. They usually have activities such as the egg and the spoon race and the sack race. Other events include the skipping race (跳绳) and the three-legged race. In middle and high schools, sports days include many of the common track and field events (田径项目).  They are more serious and competitive than primary school ones.

    Students' parents and other relatives also come to the  school on sports days. They watch children play. Many schools in the West have "mothers and fathers" races for parents to take part in!

    Although sports days are exciting, they also have some problems. According to some reports in the USA, sports days have become too competitive to be good for students. Some parents put too much pressure on the children. Some schools don't have "mothers and fathers" races any more as there is much fighting and cheating.

    With their long tusks (象牙), elephants look strong. However, it is this feature that makes the animal endangered. Many of them are killed for their tusks. People make elephant tusks into crafts (工艺品) and jewelry and sell them to rich people.
    But can these priceless body parts grow back? The answer is no, Live Science said. The elephants' tusks are actually part of their teeth. Nearly all African elephants and most male Asian elephants have these long teeth. About one-third of the tusk is in the animal's skull (头骨). The tusk has a nerve (神经) running down its center. This makes it similar to your teeth. Once you lose a tooth, you will never grow a new one.
    Elephants use their tusks to protect themselves, lift things, dig water and gather food. But losing the tusk will not kill them. The way in which they lose the tusk is what matters. Usually, people get tusks by culling (限量捕杀), which means killing old and weak elephants. They also take tusks from the elephants that have died naturally.

    However, these sources aren't enough to keep up with the demand for ivory. Therefore, some poachers (偷猎者) kill healthy elephants and cut their faces open to remove the tusks. About 27,000 elephants are killed by poachers each year, according to National Geographic.
    As a result of poaching, some African elephants gradually evolved (进化) without tusks, which has allowed them to survive. In Mozambique, about 90 percent of African elephants were killed for their tusks and meat from 1975 to 1992, National Geographic reported.
    Scientists found that about a third of younger females—the generation born after 1992—never developed tusks.

    Your schooldays should be some of the best and happiest days of your life. How can you get the most from them, and be sure you do not waste (浪费) this great chance to learn?

    Be active (积极的) at school. Don't say things are difficult or boring. Take an interest in your school life and school subjects. Take part in lots of activities (活 动). Put up your hands quickly in class. Go around the school with a big smile. If you are not working, you are wasting your time at school. Teachers can not make everything enjoyable (令人愉快的).

    Keep fit. If you don't eat a good breakfast, you will be thinking about food in class.

    If you go to bed late and don't have enough sleep, you will be sleepy in class. Play enough sports every day in order to keep your body strong.

    Face the problem. Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get back in front. You cannot finish the race if you rest all the time. Everyone fails (失败) some exams, loses some matches and has a bad day. Don't make small problems very big and important. Don't forget to ask for help if you cannot solve the problems. You are young, and no one thinks you must do everything quite well!

    Spend the weekends. Don't waste time lying in bed on Saturday or Sunday morning. Go and play sports, get together with friends in the park to relax, learn to play the piano, or help someone with problems. If you don't want to go out, there are also a lot of things to do. You may read a book, practice English or help your mum with housework.

    Follow our advice, and have a happy school life!

    Schools in the UK are quite different from those in China. In the UK, at the beginning of the term, students must select their courses and teachers first.

    {#blank#}1{#/blank#} So in the first term, don't select too many courses, or you'll feel nervous and it may influence your study. Then you have to ask for some teaching plans. There is some information about subjects, time arranging, marks and textbooks. {#blank#}2{#/blank#} Different teachers have different teaching methods.

    If the teacher is called "killer" by the last grade, many students will give up choosing him, because this kind of teacher will leave too much homework, give too many exams and too low grades.

    {#blank#}3{#/blank#} How to buy textbooks makes each student feel hard. The textbooks in the UK are very expensive. Each copy is about $30 -50. In order to save money, many students buy some used textbooks. {#blank#}4{#/blank#}

    In class, discussing is very important. The teachers always encourage you to ask questions or show your own opinions freely. They don't usually ask you to sit well. {#blank#}5{#/blank#} They usually don't give you much homework to do. So in the schools in the UK you can learn knowledge and do exercises by yourself. You must do almost all things independently.

A. And some students usually borrow textbooks from the school library.

B. At the same time, you must select the teachers.

C. Selecting is very important for your grades in the UK.

D. Instead, they allow you to sit or stand everywhere you like.

E. There is another thing after you select the courses and the teachers.
