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:
Kids should not eat more than that.

When I was ten, my mother worked all day so I had to take care of my younger brother. At that time my little brother was about four years old and he missed mum all the time.
One day, after I had given him his dinner, he started crying for mum.He was so young and really needed mum. So I dressed him, put on his shoes, carried him on my back and walked out. Soon he fell asleep. About half an hour later, I found that he had lost a shoe while sleeping. I took him off my back and put him down. I knew we needed to find that shoe, for our mother couldn’t afford new shoes. We had to go back to find it, so I told my brother to wait right there. A man heard it and stopped me just before I walked off. He asked me, “You are leaving your brother here to find the shoe? What would you do if he is not here when you return?” I did not know how to answer that question. He continued, “It’s OK if you can’t find the shoe, but it is not OK to lose your brother.” Then he sent us to mum’s workplace by taxi.
My whole life I have depended on the kindness of many strangers, I feel regretful that I cannot find them and say thank you. I do not even remember what the man’s face looked like, but he taught me a lesson—people are more important than things.

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.
C. Patricia Wright. D. Scientists from Europe.

How do you remember the way to your house? Where do dreams come from? It is your brain(大脑) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按钮)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
l Eat healthy food.
l Get a lot of playtime or exercise.
l Don’t drink or smoke.
l Use your brain a lot.
【小题1】 A British scientist found out that ________ could improve our memories.
