So they can’t learn it well. But English is very easy for me. I’m good at it. I’m very glad to tell you something about how I study English.First, I think an interest in English is very important. When I was in Grade One, we had a new subject —— English. It was fresh for me . I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! After that, I learned English harder and harder. Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!Second, I think English is a foreign language. I should learn it well in the following ways: Listen to the teacher carefully, speak bravely, read aloud and have a good vocabulary. Then practice again and again, never be tired. And I also have a good habit: Asking whenever I have a question, I must make it clear by asking our English teacher. How happy I am when I understand!Besides this, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also useful. They help me understand a lot of things. So to do more reading is an important way to learn English well.And I also do some exercises from our class magazines, and I often write English diaries. English has become a close friend of mine.Now I have learned English for more than two years. I always keep the first position in our school. From these words, I hope every student can learn English well.()1.Why do some students often “have a headache”?A. Because they are easy to catch cold.B. Because it’s often very coldC.

The smile was so beautiful that he wanted to see it again, so he gave her a Coke. She smiled once again. The boy was very happy.They sat there all the afternoon, eating and smiling, but they said nothing. When it grew dark, the boy decided to leave. But before he had gone more than a few steps, he turned around, ran back to the old woman and gave her a hug. The woman gave him her biggest smile ever.When the boy opened the door of his house, his mother was surprised by the look of joy(快乐)on his face and asked what had made him so happy. "I had lunch with Love. She has got the most beautiful smile in the world." At the same time, the old woman’s son was also surprised at his mother,s pleasure and asked why."I ate a pizza in the park with Love," she said, "and he is much younger_________ I expected."If the world is full of love, we can enjoy a better life.1题完成句子;2题简略回答问题;3题将文中横线处空缺的一个单词填写在下面的答题纸上;4题找出并写出全文的主题句;5题将文中画线句子译成汉语。

You may spend time with a friend and get to see where he lives. So remember to be polite.When to arriveThe first thing to remember is that when a friend invites you over, you need to arrive on time. If your friend tells you to come “around 3:00”, that means you can turn up a little bit after 3:00. But usually it is a good idea to arrive at the right time.What to bringOften it is also nice to bring something to your friend’s house. This could be a box of chocolates for you two to share, or maybe a movie that you can watch together. You can also bring some flowers.A little gift is a nice way to show your friend that you are excited to be at his house.How to greet (问候)When you visit your friend’s house, you may also meet his parents. You should tell them who you are and they may tell you their names. As a child, I went to visit my friend Paul. I called his parents by their first names John and Mary. But now I know it is more polite to call them Mr. or Mrs. Smith. This will show them more respect (尊重) and then they may tell you to call them by their first names. Another way to show respect is to call them Madam or Sir.It is a cool thing to visit a friend’s house. Be polite to your friend and your friend’s parents, and you will be invited again!9. If you are told to get to your friend’s house around 5:00 p.m., it is polite to arrive at_____A. 5:02 p.m.B. 4:50 p.m.C. 4:30 p.m.D. 5:30 p.m.10.

An artist will mix blue and yellow paint to get a shade of green; a scientist will mix green and red light to create (产生)yellow. The printed page in a magazine is yet another system.Scientists recognize(确认)the light primaries (原色) are red, green and blue. When mixed, red and green light rays(光线)produce yellow, blue and green produce cyan(青色), red and blue produce magenta(洋红). Red, green and blue mix to create white (light). This colour model is used in computer monitors, television sets and theater.Most artists recognize red, yellow and blue as the three basic primary colours. These primaries are the pure colours which can not be created by mixing any other colours.In the print industry, cyan, magenta, yellow and black are used as the primary colours. When you mix all the colours, the result is gray.12.__________ on the colour systems.A. Scientists and artists have the same ideaB. Scientists agree with artistsC. Scientists and artists have different ideasD. Some of their ideas are the same13. How many colour systems are mentioned in the passage?A. Two.B. Three.C. Only one.D. Four.14.

Red, green and blue are used in television sets.B. If scientists want to get white, they will mix red, yellow and blue together.C. Most artists think red, yellow and blue are the pure colours.D. In the print industry, if you mix all the colors, you will get gray.四、词汇(共15小题;每小题1分,满分15分)。
