The salted fish is a kind of popular food in ...

The salted fish is a kind of popular food in the south of China. It is delicious and adds a salty flavor to other dishes. But eating too much salted fish can give you cancer. We can see it clearly on the list of cancer­causing foods, which was recently published by the China Food and Drug Administration(中国食品药品监督管理局)．

The salted fish is produced with a large amount of salt, which later turns into nitrites(亚硝酸盐). When nitrites reach our stomach, they turn into another kind of chemical that can cause cancer.

So does this mean we can't eat salted fish anymore?

“People don't need to worry too much. Cancer is concerned with how often you eat certain foods and how much of them you eat，” Huang said. If you really like eating salted fish, you can eat a small amount once or twice a month. Meanwhile, you should also eat more fruit and vegetables that are rich in vitamin C, as this can help to prevent the formation of nitrites.

In fact, there are many foods that we often eat that are thought to cause cancer, such as pickles(咸菜), areca palms(槟榔) and so on.

Although these foods may bring cancer, it doesn't mean a person will get cancer just from eating them. Cancer is caused by many different factors, such as one's genes, environment, lifestyle and eating habits. As long as one has a balanced diet, he doesn't need to avoid cancer­causing foods entirely.

Do you like Physics or Chemistry? Matter (物质) is always changing, either physically or chemically. If a material goes through a physical change, it is still the same material. During a chemical change, one kind of matter changes into another completely different kind of matter. For example, when we burn wood or cook fish, materials change. People use chemistry every day in the kitchen. The food we eat has many different natural chemicals. Many of the chemicals in food are necessary parts of a healthy diet.

Much of the food we eat has been changed in some way from its original form. The changes that food undergoes may be chemical or physical. If a change does not affect the food’s chemical composition, we call it a physical change. For example, melted (溶解的) cheese has gone through a physical change. It gets softer when it is heated but it is still the same type of material. Any change that changes the chemicals in the food is a chemical change. Bread contains carbohydrates, which are chemicals made up of carbon, hydrogen, and oxygen. When bread is baked (烘焙), the carbohydrates break down into black carbon and water. The carbon gives the bread a dark color and a crunchy texture (质地). The water goes into the air.

To get a closer look at the chemistry of baking, let’s watch how a carrot cake is made. The main steps of baking any cake are mixing the ingredients (材料) and baking them together. In the course of making cakes, the dry ingredients are mixed first. They are flour, sugar, salt, baking soda, baking powder and spices. Flour gives the cake structure. Sugar helps to make it sweet. Salt strengthens the cake batter. Baking powder and baking soda make the cake rise.

Next, the carrots may be added to the cake. These help give the carrot cake its flavor, texture, and color. The other ingredients in the carrot cake are oil and eggs. The oil makes the cake tender and moist. Eggs serve two purposes—the whites help the cake to rise, while the yolks (蛋黄) give it a creamy texture. All of these ingredients form a mixture. This mixture can be separated into its different components (成分) although it is very difficult. Once the cake mixture is formed, it’s poured into a cake pan and baked in an oven. The heat from the oven has caused chemical changes to take place. The cake is finished and the ingredients cannot be separated.

1.The material doesn’t change when we _______.

A.melt ice cream B.burn paper C.bake apple pies D.cook beef

2.What’s the correct order of baking a carrot cake in the passage?

a. Carrots, oil and eggs are added.　　　　　　 b. The dry ingredients are mixed.

c. The mixture is baked in an oven.　　　　　 d. Baking powder and soda make the cake rise.

e. Preparing some dry ingredients.　　　　　　 f. The heat from the oven causes chemical changes.

g. The ingredients cannot be separated.　　　　 h. The mixture is poured into a pan

A.b-a-h-f-g B.b-h-c-d-f C.e-d-c-a-g D.e-c-a-g-d

3.After reading the passage, we know that ________.

A.water and carbon can give the cake a dark color and a crunchy texture

B.people can separate the mixture of eggs and oil into different components

C.chemicals in different kinds of food that people eat are bad for their health

D.sugar and salt can’t be put into the mixture to make a cake at the same time

4.The passage mainly helps us to _______.

A.look at the steps of baking cakes closely

B.learn how to make carrot cakes at home

Before winter arrives, many kinds of birds know that it is time to fly south. The migration (迁徙) has always made us think hard. Why do only some birds migrate? How do birds know when to go south? How do they find their way?

Some birds fly south because their food supply runs short in winter. The woodpecker (啄木鸟), for example, doesn't need to fly south because it can find food in the bark (树皮) of trees. Some birds eat grains, insects and other food that disappear in winter, so they must fly south where food can still be found. But why don't they stay in the south? Perhaps they know that if they stayed down south, they would run out of food there, too.

It is possible that birds know when winter is coming because they find that the days are getting shorter. Once they leave from the north, they use the sun as a compass. The sun is in different positions in the sky at different times of day. To use it as a guide, birds would have to know the time of day. On long flight, most birds use the stars to navigate (导航) their way.

The homing pigeon (信鸽) doesn't use the sun or the stars. Scientists believe that it uses the magnetic field (磁场) of the earth. One of the most amazing migrations is that of the tiny hummingbird (蜂鸟). It travels from Canada to Mexico—a long distance of over 3,600 kilometers.

1.It is believed that some birds fly south because ________.

A.they need food B.they like warm weather

C.they get lost D.it is just a habit

2.On long migration flights, most birds find their way with the help of _______.

A.the stars B.other birds

C.the moon D.the magnetic field

3.Which of the following is NOT true according to the passage?

A.The woodpecker usually doesn't need migration.

B.The hummingbird flies to Mexico for food.

C.Birds migrate before winter comes.

D.Birds that eat insects like staying in the south better.

It's a common belief that fish can't remember anything for longer than seven seconds. It may seem sad to think that every moment in their lives would be like seeing the world for the first time. But don't be so quick to feel sorry for them. A new study has found that fish have much better memories than we used to think.

In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They took the fish out and then waited for 12 days before putting them back in the tank again. They found that after such a long break the fish sill went to the same place where they first got food.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. But there was no clear evidence until the latest findings.

Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. "If fish are able to remember that a certain area contains(容纳) safe food, they will be able to go back to that area without putting their lives in danger," lead researcher Trevor Hamilton told Live Science.

So next time you are watching your pet fish from outside the tank, perhaps you should feel close to them-they may remember who you are.

1.We often feel sorry for fish because __________.

A.they have bad memories B.they can't remember anything

C.they are often used for research D.every moment in their lives is new

2.Why did the researchers carry out the research?

A.To know if fish can find food easily. B.To find out if fish have better memories.

C.To tell us fish can live for days without water. D.To show fish can live long without eating things.

3.What does the underlined word "tank" in Paragraph 2 mean?

A.A kind of fish food. B.A kind of hiding place.

C.A container for holding water. D.A container for keeping fish.

4.Which is true according to Trevor Hamilton?

A.Fish know where to get food. B.It's easy for fish to live in the wild.

C.A good memory can make fish safer in the wild. D.Fish are often in danger when they look for food.

5.Where does this article probably come from?

A.A story book. B.A science magazine. C.A news report. D.A travel book.

Americans work hard, and they don't have much time to eat meals. American families don't often eat dinner together. For example, children may eat earlier or later than their parents. When American mothers work late, their children sometimes cook their own dinners. Americans eat lots of snacks, and get cheap meals like hamburgers and French fries from restaurants. These are called"fast food"because people don't have to wait long for their order. Now more and more people find them a problem because they aren't healthy.
