Recently, more and more people pay attention to eating healthily. Some food additives(添加剂) are used to make different kinds of foods. Some of them can make the food more delicious and some of them can make it colorful. But lots of chemicals are used to produce what we eat every day.
Sudan red is a kind of chemical that factories used it to dye cloth, make the shoes brighter. But some people produced salted duck eggs with it . However, it isn’t a kind of food additive. The food made from Sudan red makes it easier to cause cancer. Melamine(三聚氰胺) is another kind of chemical that are banned(禁止). It’s white crystal(晶体), which was discovered by a German chemist called Sustus Von Liebig in 1834. Melamine can be used to make paper, medicine and woods, ect. But nobody can imagine that some people used it as a material of milk powder(粉末). Because of melamine, it’s reported that 4 babies died and more than 50 thousand babies are affected since 2008. Sanlu, a famous milk powder factory was closed. What’s worse, milk powder with melamine appeared in 2011 again. Problems of food safety, for example, poisonous rice, lean meat powder(瘦肉精) and plasticizers(塑化剂) are becoming more and more serious.
Fortunately, lots of laws have been made to make the solution(解决方法) better. We think we will eat more healthily in the future.

Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren’t there many factories like the Symi factory?
In some places the sun is not hot enough. Or it does not shine every day.
In such places other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried.
One way is freezing. The fresh part of salt water freezes first. To get fresh water, the bits of ice are taken out.
Which way is the best? The one that gives the most water for the least money. It may be a different way for each place.
Symi’s way seems very good for small, hot places. It does not make much water at a time. But the factory is easy to build and costs little.
That is why people in many dry places talk about Symi. 
小题1:From the passage we know that fresh water _____________.

Robots have come a long way since 15th century. We’ve got robots to build cars, carry heavy things, work in dangerous places and explore planets. But things haven’t stopped there.
In 1986, Honda made a robot called ASIMO. And now, it has been developed greatly. Standing at 130cm and weighing 54kg. ASIMO is very much like a small astronaut wearing a bag on the back. And he can walk, flight, climb and run fast. Isn’t it wonderful?
The world’s first robot teacher is Saya. With her human-like face, she can show expressions like happiness, surprise, sadness, dislike, fear and she can even smile or show anger at students, which look much like a real teacher’s. To do this, her rubber skin is pulled from the back with motors inside. And her eyes and mouth have wires(电线) too. She can also say some simple words like “hello” or “thank you”.
In the UK, the development of robots is exciting. The mini-robots will send food, clean floors, collect and throw away waste. These robots can open doors by themselves and stop if anything or anyone is in the way.
These mini-robots are very useful for controlling infection(传染). Usually clean and dirty work is done by the same person, but here, you’ll have robots that do”dirty work”, like collecting dirty sheets, or taking away hospital waste; and you’ll have robots that do”clean work”, like bringing meals or clean sheets to patients. The robots have separate work so there’s no way for infection, which is great. But of course, robots would not take the piece of humans, but would free up more time for nurses to be with patients.
But if this is what it’s like in 2011, what’s it going to be like to 2021?
小题1:In the following, which is ASIMO’s behavior?
A．Smiling at people, saying “hello”.
B．Sending food or opening doors by himself
C．Fighting, climbing or running fast
D．Collecting waste for patients
小题2:What makes Saya look real?
A．Her face and rich expressionsB．Her clothes and shoes
C．Her walking and running speedD．Her rich knowledge
小题3:Which of the following is true according to the passage?
A．Robots have come a long way since 1986.
B．The first robot teacher was made by Honda.
C．Saya looks like a small astronaut.
D．If anyone or anything is in the way, mini-robots will stop.
小题4:The main idea of Paragraph 5 is that _______.
A．nurses would have more free time with patients
B．robots would not take the place of humans
C．dirty and clean work is always done by the same person
D．mini-robots are useful for controlling infection
We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (壳) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.
小题1: A snail _________.
A．moves more slowly at nightB．has thousands of feet
C．doesn’t move at all　　D．sleeps much of the time
小题2: In the sentence “A snail draws its body into its shell”, the word “draw” means _____.

C．a snail’s nose is quite short D．a snail’s body changes in different seasons
小题4: A snail goes to sleep when _____.
A．it feels hungry B．it is put into a paper boxC．spring is coming D．it rains heavily
小题5:Which of the following is wrong?
A．In winter the snail doesn’t eat or move.B．A snail doesn’t like living under the sun
C．The snail’s teeth can’t be worn out.D．The snail’s nose helps to find food.
We have always been warned of the dangers of forest fires. They cause _____ 85 _____ to a forest. They kill many plants and animals in an eco-system, which is a group of living things and their environment. But have you ever heard of a forest fire that can be _____86_____  for a forest? People start some of the fires with a special reason to actually do good to the eco-system.
In fact, fires are a natural part of any eco-system. Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can _____87_____ some of these old trees. When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.
Some trees even need fires to grow. These trees hold their seeds (种子) inside. Heat from a fire allows the coat of the seeds to open up. Then the seeds fall to the ground and have the _____88____ to grow/
Scientist, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or _____89_____ a after forest fires, they can go hungry _____90_____ their food has been damaged in the fire. Small, controlled fires mean than animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This _____91_____  makes an eco-system.
So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.

Most children don’t enjoy doing housework. They like playing computer games rather than cleaning the rooms. But in Australia, Jim and Robert’s mother, Mrs Black, has good and proper methods to get their children to do housework.
Here is an example.
“Mum, have you worked out next week’s housework? Let Jim and me choose the cards I can’t wait. It’s fun!”
When Robert shouted out, his mother had already put all the cards on their big table. On the cards, there are some words like these, “sweep the floor, clean your bedroom, help mum cook, wash vegetables, make beds, feed the fish, cut the wood, clean the bathroom” and many others, Jim and Robert chose two cards for each day from Monday to Friday. Then they would hang them on the week day task board. Jim likes to clean the bathroom, so he picked up the card “clean the bathroom”. Robert loves to make the bed so he picked up his favorite card. Jim again picked up “wash vegetables” and Robert chose “feed the fish”. Soon the two boys were happy to take away all the cards
To help the children do housework, their mother thought hard and came up with this idea. Of    course, the parents did the housework on the weekends and left Jim and Robert two days free.
