When you look at your food, some ingredients are easy to see. For example, there is cheese on your pizza and butter on your bread. But our meals are also filled with ingredients you can’t see. And you might be surprised to learn just how much those hidden (隐藏的) ingredients affect your health.
Salt is a perfect example of an ingredient that you might not notice, even when you eat a lot of it. More than 75% of the salt we eat is hidden in restaurant meals, fast food and processed (加工过的) food , such as French fries, hot dogs and even biscuits.
Salt is important to us. It keeps our muscles (肌肉）working and our nerves (神经）sending  messages through the whole body. Salt can be used to clean teeth, to make our skin smooth or added to a relaxing bath. Salt is also used to help make food last (持续) longer.
However eating too much salt can cause heart problems. For a long time, heart trouble has been regarded as an adult problem, but new research shows that salt is starting to affect kids. Then how much salt is safe for kids every day? Let's look at the following chart:

Ages	Amount of Salt Every Day
1—3 years old	2 grams
4—6 years old	3 grams
7—10 years old	5 grams
11 or more than 11 years old	6 grams

Kids should not eat more than that.

A fish that lives in America can live out. of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.
The Mangrove Rivulus, a kind of little fish, lives in small pools of water. When their living place dries up, they live. on the land, said Scott Taylor, a researcher in Florida.                        
The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.
The new scientific discovery came during a trip.
"We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out," Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish(肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active(活波的)way. But no other known fish can be out of water as long as the Mangrove Rivulus and keep active, according to Patricia Wright, a biologist at a Canadian University.
More studies of the fish may tell how animals changed over time.
"These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land," Wright said.
【小题1】The Mangrove Rivulus is a type of fish that_________.

【小题2】Who will write a report on Mangrove Rivulus?
A, Scott Taylor.                     B. Some reporters.

【小题3】According to the passage, lungfish can___________.

A．breathe through its skin	B．be found in Asia

【小题4】Which one of the sentences below is not true?

B．Millions of years ago, animals began to live onto land from water.

C．Lungfish found in Australia, Africa and South America can live out of water in a not active way.

D．The walking catfish found in Southeast Asia can stay on land for hours at a time.

If you want to become a better reader, what should you know about speed of reading?
Some people read very rapidly(很快地), while others read very slowly. But which one is
better?
The rapid reader may be a good reader when he reads a storybook for fun. But he may not be
able to slow down enough to read directions(说明) carefully. He may read so rapidly that he does
not take time to understand fully the ideas and information which are important to remember.
The slow reader may be a good reader when he reads directions for making something. But he
may spend too much time in reading a simple story which is meant to be enjoyed but is not
important enough to be remembered.
So, you see, either a rapid reader or a slow reader is not really a good one. If you wish to
become a better reader, here are four important things to remember about speed of reading.
1. Knowing why you are reading will often help you to know whether to read rapidly or
slowly.
2. Some things should be read slowly throughout. Examples are directions for making or doing
something, science and history books, and Maths problems. You must read such things slowly or
remember each important step and understand each important idea.
3. Some things should be read rapidly throughout. Examples are simple stories for enjoyment,
letters from friends and bits of news from hometown papers.
4. In some of your reading, you must change your speed from fast to slow and slow to fast, as
you go along. You will need to read certain(某些) pages rapidly and then slow down and do more
careful reading when you come to important ideas.
【小题1】 What should be read rapidly?

A．Directions for making something.

B．Maths problems.

C．Science and history books.

D．Storybooks, newspapers, personal letters, etc.

【小题2】What is the important thing you should keep in mind about speed of reading?

A．To read as fast as you can.	B．To fit your reading speed to your needs.
C．To read as slowly as possible.	D．To keep your reading at a certain speed.

【小题3】Which title best gives the main idea of the passage?

A．Something about Careful Reading	B．Be a Rapid Reader.
C．How to Read?	D．How to Be a Slow Reader?

When my son, Mark, was in the third grade, he saved all his pocket money for over three months to buy holiday presents. The third Saturday in December Mark said he had made his list and had twenty dollars in his pocket.
I drove him to a nearby supermarket. Mark picked up a hand basket and went in while I wailed and watched in the car. It took Mark over 45 minutes to choose his presents. Finally he came to the checkout counter (交款处) and reached into his pocket for his money. It was not there! There was a hole in his pocket, but no money. Mark stood there holding his basket, tears falling down his face.
Then a surprising thing happened. A woman came up to Mark and took him in her arms. "You would help me a lot if you let me pay for you," said the woman. "It would be the most wonderful gift you could give me. I only ask that one day you will pass it on. When you grow up, I would like you to find someone you can help. When you help others, I know you will feel as good about it as I do no."
Mark took the money, dried his tears and ran back to the checkout counter as fast as he could. That year we all enjoyed our gifts almost as much as Mm-k enjoyed giving them to us.
I would like to say "thank you" to that very kind woman, and tell her that four years later, Mark went house to house collecting blankets (毯子) and clothes for the homeless people in the fire. And I want to promise her that Mark will never forget to keep passing it on.
