What can you do on the Internet? Many of us like to read the news, buy things and play games. Some students now have a new use for the Internet – helping them with their homework.
Tina, 14, from Shenzhen, Guangdong, often searches online for the answers to her math problems. She said sometimes she and even her parents don’t know the answers to the problems, so she has to turn to the Internet.
“I can see how other people work out these problems and learn from them,” Tina said. “It’s easy and saves time.”
But not all the students welcome this. Leo, 15, from Hangzhou, Zhejiang, thinks it may make students stop thinking.
“We should think over the problems first. Simply copying the answers won’t improve our abilities. ” he said.
In the eyes of Wang Zhaoming, a Shanghai teacher, the success of all this is down to the students. If they use the Internet properly (適當?shù)?, it could be a good tool for study, Wang said.
“Students should first think about the problems by themselves. As for the online answers, they should choose the best among different ones. The most important thing is to know the logic (邏輯) behind the answers,” he said. “Don’t be shy to ask teachers and classmates the next day if you don’t understand the answer.”
小題1:According to the passage, it’s a new use for students to ___________ on the Internet.
A.buy thingsB.play gamesC.help with homeworkD.read news
小題2:The right order to use the Internet to help with our homework is ____________.

② Search the answers on the Internet;
③ Think about the problems by ourselves;
④ Try to understand the logic behind the answer you’ve chosen.
A.①②③④B.③②①④C.②③①④D.④③②①
小題3:In Leo’s opinion, searching online for the answers may _______________. 
A.make students simply copy the answers instead of thinking
B.help solve the problems between students and their parents
C.be a good tool of study if students use the Internet properly
D.improve the students’ different abilities

Is learning a foreign language ever easy? Yes. If you are five and move to another country, you will quickly pick up the language. But what about for the rest of us who are no longer five, and need to be polite when traveling for business or for pleasure? I think that answer is also yes. Language learning can be easy if you don’t want or need to learn too much.
The key to successful language learning in my mind is not to set the goal too high. It is rather like running. Even if you run twice a week, you don’t necessarily want to be able to run a marathon (馬拉松). You might just want to keep a level of fitness. I think the same can be true for language learning.
Let’s get back to the goal. If you decide to learn ten words in a foreign language before visiting the country, you know that you will be sure to do this. However, if you decide to talk to people with great fluency (流利), unless you are quite a talented person, you will probably fail and give up in half-way.
It is also far easier to start learning a foreign language than to finish. In other words, the better you are, the slower it can be to improve, because you will not be able to move further because of grammar, making sentences, learning less common words, etc. If you are only trying to learn a few foreign words and sentences, you will enjoy faster progress, have more fun, and won’t have to spend too much time.
The idea of learning only a few hundred words in a language, and then stopping, isn’t the usual way to language learning, but it can be a very meaningful and enjoyable activity.
小題1:In the writer’s opinion, it is easy for adults to learn English if _______.
A.they are especially talented people
B.they don’t want or need to learn too much
C.they have to spend a lot of time on it
D.they have a chance to go abroad
小題2:The writer believes that if you want to be good at a foreign language, you will probably _______.
A.forget your own goals
B.become a talented language learner
C.get tired of learning it
D.reach your learning goal
小題3:The best title of this passage would be _______.
A.Easy Language Learning B.Hard Language Learning
C.Fluency in a Foreign Language D.A way of Language Learning

It's important to learn about protecting our environment. Here is a 5R rule for us:
1.Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste
2.Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat(壓平)and melted(融化)and the melted things are made for new coke cans.
4.Recover
When you buy a box of apples, there may be a few rotten(腐爛的)apples, You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5. Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a "throw-away" society(社會).But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
小題1:_______can be recycled.
A.Only hard things B.Many thingsC.Few soft thingsD.A11 things
小題2:The "recover' rule mainly requires us_______.
A.to throw waste things awayB.to cover waste things with earth
C.to get back the useful partsD.to throw the whole things away
小題3:We can infer(推斷)that the writer of this passage may live in_______.
A.ChinaB.JapanC.AustraliaD.America
小題4:Which of the following is true?
A.We will have no resources(資源)of nature unless we can do with the waste.
B.Recycling is the best way to save resources.
C.If we waste less, we can save more resources of nature
D.More things are wasted in developed countries than in developing ones.

Ding-Dong!
“Jason, honey? Can you answer the door?”
“I am busy, mom!” Jason shouted back at his mother. He had spent three hours so far working to this point in the game. He couldn’t stop now.
Ding-Dong!Mom′s footsteps approached the front door.
“Jason, it’s your friend Todd.” Mom called from the doorway.
Todd, his best friend, stepped into the room. “ Jason!I need a partner for playing basketball. ”He sounded excited.
Jason snorted. “No way, Todd. I′m playing a game here.”
Jason gave his friend a dirty look, and his character in the game almost got killed while he looked away, “ I almost died because of you!”
Todd looked at Jason′s mother. Jason’s mother looked back at him. They both looked at Jason. “Why don′t you play basketball with your friend?” Jason’s mother suggested.
“Tomorrow, maybe…” There were more levels to beat tomorrow, though, Maybe he had played tomorrow. He’d have to see what mood he was in. He thought he heard footsteps walking away, but he was too busy beating the next level to care.
An hour later, Jason’s father came home. It was dinner time after his father washed up and sat down. Jason didn′t even hear his name being called to the table. He didn′t hear his father walk at behind him and ask him to turn the game off, either.
When the screen suddenly went black and his father’s angry face loomed in front of him, Jason finally heard. “No more game for a month.” Jason′s father shouted at him. “You don’t play basketball, you don′t come to dinner, and you don′t do your chores. We′ll make you do something else before you play any more.”
Jason nodded slowly. He knew better than to argue with his father, and when he thought about it, he had been playing quite a bit. It was fun, but he was letting down his friends, his family, and himself by paying too much.
He′d try harder in the future.

If you have a bottle of water recycled(再利用) from urine(尿), would you drink it? Astronauts at the ISS may soon do so.
NASA(美國航空航天局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.
At present, each ISS astronaut uses about 4.4 liters(升) of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $ 11,000.
The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.
Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria(細菌). Scientists say that the recycled water is thousands of times better than the water from a city tap.

Eating in space is different from eating on the earth. The food that astronauts carry with them does not look like the food you eat.
Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship, the astronaut puts the water back. He “shoots” hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag.
Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cakes often come in bite-size pieces.
Astronauts cannot drink water from open cups. The water would float in drops in the spaceship. The water is put in the special gun. The astronaut shoots the water into his mouth.
小題1:Some food carried in the closed bags by astronauts is ________.
A. cooked and frozen      B. full of water            C. raw
小題2:Astronauts can’t drink from open cups because__________.
