How do you remember the way to your house? Where do dreams come from? It is your brain(大脑) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按钮)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
Eat healthy food.
Get a lot of playtime or exercise.
Don’t drink or smoke.
Use your brain a lot.

A kind of little cars may be seen in the streets in the future. People will like this kind of small cars better than the big ones. The car is as small as a bike. But it can carry two people in it. Everybody can drive it easily, just like riding a bike. Even children and old people can drive them to schools or parks.
If everyone drives such cars in the future, there will be less pollution in the air. There will be more space for all the cars in cities, and there will also be more space for people to walk in the streets.
The little cars of the future will cost less money to buy and to drive. These little cars can go only 65 kilometers an hour, so driving will be safer. The cars of the future will be fine for going around the city, but they will not be useful for a long trip.
This kind of cars can save a lot of gas. They will go 450 kilometers, then they have to stop for more gas.

My summer hols wr CWOT. B4, we usd 2 go 2 NY 2C my bro, his CF & thr 3:-@ kids FTF ILNY, its gr8.
　　Can you understand this sentence? If you can"t, don"t feel too bad: neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on Internet or cellphones. To newcomers, it can look like a completely foreign language. So, what is the "translation" of the sentence above? My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face. I love New York; it"s great.
　　Schoolteachers and parents say this new form of writing is harming（破坏）the English language. Increasing spelling and grammatical mistakes cxan be seen in students" writing. They fear the language could become corrupted（面目全非的）.
　　Everyone should just relax, say linguists（语言学家）. They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nunberg, from Stanford University, agrees. "People get better at writing by writing," he says, "Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than, their parents."
　　Linguist James Millroy says, for centuries, it is believed without exception that young people are harming the language. And you can bet your bottom dollar that when today"s teenagers become tomorrow"s parents, they too will think this way. Milroy argues that languages do not and cannot become "corrupted"; they simply change to meet the new needs.
　　However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, "I can understand Netspeak worries teachers and it"s important that they get across to their pupils that text messaging is for fun, but that learning to write proper English is a must for their future."
　　Perhaps we should give teenagers a little more trust anyway. Erin, age 12, says, "I wouldn"t use text language in my homework. Texting is just for fun"
　小题1:What is the main purpose of the first paragraph?

A．To give an example of a foreign language.

B．To show an example of creative methods.

C．To express worries about using Netspeak.

D．To lead in the topic of Netspeak.

　小题2:Which of the following is true according to the passage?

A．Cynthia McVey points out teenagers can deal with Netspeak properly.

B．Geoffrey Nunberg believes Netspeakers can write Standard English.

C．David Crystal thinks Netspeak helps develop the habit of writing.

D．James Milroy says that language is changing and improving.

　　小题3:The expression "bet your bottom dollar" in Paragraph 5 means ______.

A．be fairly sure	B．be greatly surprised
C．think it a pity	D．find it interesting

　　小题4: What can be the best title for the passage?

A．Netspeak: A Widely-Used Language on Internet

B．Is Netspeak Harming the English Language?

C．Is Netspeak Helpful in Language Learning?

D．Netspeak: Advantages and Disadvantages

　　We need to be responsible for our environment. Being a frugal consumer(节俭的消费者) is one way to help. But, what exactly does that mean?
　　Use It Up
　　You can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use the last little piece of soap. Don"t throw away any bits of the biscuit at the bottom of the box.
　　Wear It Out
　　You do not always need to have new things. Suppose your sneakers have broken laces, but they still fit you. Repair them and wear them longer. You don"t have the latest iPhone until the old one doesn"t work anymore. Then you can get a new one. Think twice before replacing something that still works.
　　Make It Do
　　When something you want is not on hand, look for something else that you already have to take its place. Suppose you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just throwing them away. With a little thought, you can make something do, instead of buying something new.
　　Do Without
　　Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy you saw on TV? Making the things that we want uses up your world"s resources(资源). And, getting rid of the things we don"t want any more takes up even more resources and space.
　小题1:Do we need to be responsible for our environment?
　小题2: How do we deal with the last little piece of soap?
　小题3:When do we need to get a new iPhone?
　小题4: What should we do when something we want is not on hand？

Everyone has got two personalities (性格) —the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control yourself, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by new ideas. You don’t like to make people unhappy, so you never express your real feelings. You’re quite shy and you aren’t very confident.
If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you’re always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.
If you sleep on curled up (蜷缩), you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You’re shy and you don’t usually like meeting people. You like to be on your own.
If you sleep on your side, you have usually got a well-balanced (平衡的) personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel worried, but you don’t often get unhappy. You always say what you think, even if it makes people angry.
