8.The weather is getting hotter.You are thirsty after playing basketball or riding home from school.A cold drink may be just the thing.But be careful what you are drinking.Something that looks cool may not be good for your health.
There are plenty of"energy drinks"on the market.Most of them have beautiful colors and cool names.The lists on them tell you they are helpful to your health.Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them.These drinks are especially aimed at (针对) young people.Makers sometimes say their drinks make you better at sports and can keep you awake.But be careful not to drink too much.
Caffeine makes your heart beat fast.Because of this,the International Olympic Committee has limited (限制) its use.Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea.Possible health dangers have something to do with energy drinks.Just one box of energy drink can make you nervous,have difficulty sleeping and can even cause heart problems.Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

Rubbish sorting (分类) probably doesn't sound like much fun. But there is a new mobile game that may change your opinion about it, and you might even learn something while you play it-Meet Sortee.

Meet Sortee is a puzzle game developed by Flow Studio, a UK company. It makes you think deeply about everyday objects and their meanings.

The rule of the game is quite simple. Two bins are placed on either side of the screen. Each of the bins has a label (标签) next to it and the label explains what it is for. When an object, such as a car or an apple, appears on the screen, you need to decide which bin it should be sorted into and then send it there by moving your finger.

The game seems easy enough at first. But as you move on to more levels, it gets harder. The number of bins increases to three or four and the time given gets shorter. You need to think and move faster. That can be really difficult.

There are 400 0bjects in total and more than 100 bins in the game. The more objects you correctly sort, the more game coins you can get It's a bit like working in a rubbish recycling center, but it has no bad smell.

You can download the free game from Apple's app store (苹果软件下载中心), but it only lets you play the first few levels. If you want to open the next 40 levels, you need to pay 6 yuan for the full game.

1.The passage is probably taken from __ __.

A. a postcard B. a newspaper C. a comic book D. a novel

2.Which of the following can we infer (推断) from the passage?

A. You can play the full game for free.

B. You can play the full game easily.

C. There are only 2 bins in each level.

D. There are over 40 levels in the game.

3. What's the best title of the passage?

A. A mobile game. B. Rubbish sorting.

C. Apple's app store. D. A recycling center.

13.There is not enough oil in the world now.As time goes by,it becomes less and less,so what are we going to do when it runs out?Perhaps we will go back to using horses,carriages and bicycles.
In the Second World War,some people didn't use gas made from petroleum(石油) in their cars.However,they made gas from wood and plants.The cars didn't go fast,but at least they ran,so this was better than nothing.However,in the future,we can't cut down all our trees to make gas; we need our trees for other things,too.
Besides different types of gas,we can also use electricity to run our cars,but first we must make the electricity!Some countries have coal and they make electricity with that,but we might not always have coal,either.Other countries have big,strong rivers,and they can use the power of water to turn turbines(涡轮机)and make electricity more easily and cheaply.
We are also able to get power from the ocean tides(潮汐).We put turbines into the mouth of the river.Then the tide comes in,the water turns the turbines and then it goes out,it turns them again.
Which of these ways will be used to run our cars in the future?

61.When might people have to go back to using horses and carriages?B
A.When they are poor.
B.When they run out of oil.
C.When they need more exercise.
D.When they aren't any big trees in the world.
62.What did some people use to make gas in the Second World War?C
A.Water.
B.Coal.
C.Wood and plants.
D.Tides.
63.How many ways are suggested to make electricity in the passage?D
A.2.
B.5           
C.4                  
D.3
64.According to the passage,which of the following statements is TRUE?B
A.There is more petroleum than we can use now.
B.Trees are needed for some other things besides making gas.
C.We got electricity from ocean tides in the old days.
D.Gas wasn't used to run cars in the Second World War.
65.The passage is mainly aboutB.
A.how to run our cars            
B.what to do when oil runs out
