Next you need some friends to be in your club with you. _73_ All you need is three or four other people who are interested in the same thing as you.
_74 You should all sit down somewhere together with lots of pieces of paper and write down every name you can think up. That’ll keep you busy for ages.
At your first meeting you should make up a rule book. And the first rule should be no grown-ups or little/big brothers or sisters! The best clubs are always secret!
Now you have just about everything you need, except membership cards. These are very important and again you can speed a lot of time making them. 75 Why not leave some space for a photo of yourself? That will make the membership card really look like it.

第四篇：
Hollywood movies are regularly filled with sex and violence. They can be exciting films but sometimes all you want is a little light-hearted entertainment.
Have you heard of Bollywood? All singing, all dancing and unrealistic, it is the perfect alternative to normal Hollywood movies. Bollywood is the Indian film industry, based in Mumbai, formerly known as
Bombay. 1 Yet Bollywood is the largest producer of films in the world. This year the Indian Filmgare Awards, Bollywood's Oscars, turn 50 years old.
The typical Bollywood movie usually has the following ingredients: a cup of romance, a tea-spoon of comedy, a dash of international sight-seeing, served with a huge slice of singing and dancing. There will also be one brave hero, one beautiful heroine and one baddie. 2
Bollywood films are full of ideal things and free of daily worries. 3The actors change clothes and locations within a single song. But the audience don't mind. To Indian movie lovers, especially the poor, such films are a gateway to heaven and the stars are their gods. The films take them to a magical world away from their everyday troubles. The films tell them the impossible is possible and that true love conquers all.
4Behind the beautiful scenes, Bollywood still emphasizes traditional family values. In most films, if two lovers want to break an arranged marriage, they can't just run away. They must win over their parents.
Bollywood is a decent refreshing replacement for those over-stimulating Hollywood films. 5They will take you to a brighter, cheerier and more colorful world, where it's still cool to dance around a tree and sing a love song.
A．Bollywood has gradually won its reputation on the world stage.
B．There is never any mention of politics, poverty or war.
C．Most Chinese school kids have probably never seen an Indian film.
D．Bollywood films are mostly comic romances with light-hearted incidental music.
E. Bollywood pays great attention to traditional values.
F．The result is a fun-filled musical.
G．So if you're tired of all that Hollywood actions, check out the following Bollywood films.

The weather’s nice, and the youngsters are out of time. Here are a few tips to help you along the way: Nature is all around us. 37 For small kids, there’s likely plenty in the backyard, courtyard, or schoolyard. National parks are great, but kids foster a deep connection with nature close to home! 38 Don’t worry too much about what to do once you arrive at your nature-rich destination. What kids really need is free time to engage all their senses and use their imaginations. You can learn too. What counts is simply to get out there, show that you value the outdoors, and be ready to have fun. 39 In fact, it is not necessary for you to know anything at all about science or nature. And remember, questions are more powerful than answers anyway! Sit back and watch your kids learn. Don’t be too much of a helicopter parent, always saying “no”. Instead, try to spare more time to stay with your kids when necessary.

【专题训练】阅读七选五专题训练六 第二节(共5小题；每小题2分,满分10分) 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 （1） On the first day of my new high school, I almost had a nervous breakdown. Everything about the school seemed so difficult. When I got home, my parents said, “You’re nervous and that’s okay. Everyone is afraid of high school.”36 I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends. On the first day I was late for every class and was constantly lost. 37 Was thi s how the whole year was going to be? I didn’t think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it! The schoolmates seemed to regard me as a fool, and they were probably right. 38 With the exception of falling up and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad. It was actually much better than middle school and much more challenging. Since then, I’ve been elected vice president of my class, which wasn’t much of a victory since only three people ran for the four positions. It is normal to be scared about a new school.

高一英语七选五训练二十七 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Americans use many expressions with the word “dog”. People in the United States love their dogs and treat them well. 1 However, dogs without owners to care for them lead a different kind of life.The expression, to lead a dog’s life, describes a person who has an unhappy existence. Some people say we live in a dog-eat-dog world. 2 They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog. 3 This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dognew tricks. They believe that older people do not like to learn new things and will not change the way they do things. 4 People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. Mean dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite. Dog expressions are also used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. 5 . A. Still, people say every dog has its day. B. We do not want it to rain cats and dogs. C. Some people are compared to dogs in bad ways. D. Dogs are their best friends and they are loyal to people. E. There are many other expressions waiting for you to explore. F. That means many people are competing for the same things, like good jobs. G. They take their dogs for walks, let them play outside and give them good food and medical care.
