1 . Water plays an important role in keeping you healthy. This should come as no surprise. Much of your body is made up of water, after all. It keeps your body working properly. But did you know that too much water can poison (使……中毒) you?

Water poisoning happens when people drink too much water. This makes sodium (钠) in their blood too little.

You probably already know that too much sodium can be unhealthy. That’s true, but too little is also harmful. When you have too little sodium in your body, a lot of things will go seriously wrong in your body. Then you will feel really terrible.

Your brain may begin to go wrong. You may get a headache, feel very tired and want to throw up. In these cases, water poisoning can be deadly. You will need to be sent to a hospital right away.

Protecting yourself from water poisoning may seem easy—just don’t drink too much water, right? In some situations, however, this is easier said than done. For example, when you do some heavy exercise, such as running a marathon, you may have to drink a lot of water. It is then important to balance the number of water you drink with the number of water your body is losing. This can help you stay healthy whenever you are exercising.

So, how much water should a person drink each day? For years, we have been told to drink two liters (升) of water a day. But in fact, the actual number needed is different for each person. Today, most doctors are telling people that they should drink water whenever they feel thirsty. We can’t live without water. Neither can we live with too much water in our bodies. Make sure you take the right number of it each day—staying healthy is all about staying balanced!

G．Have a good rest (休息) every day.

6 . Once you begin to eat potato chips, you may keep eating until the bag is empty. Have you ever experienced this? Why can’t you stop eating these salty chips? Scientists said it is due to a kind of neuron (神经元).

Scientists at the Beth Israel Deaconess Medical Center in Boston have found that some neurons can make us want to eat salt.

The neurons take note of whether our bodies are lacking sodium (钠), a main part of salt. Then, they send signals (信号) to our brain to encourage us to eat more salt, according to the Daily Mail.

How do these neurons work?

Scientists did experiments on mice. They found that when mice lack sodium, their body gives off a kind of hormone (荷尔蒙) called aldosterone (醛固酮). This hormone then makes these neurons become active.

More research showed that adding salt to meals makes people enjoy their food more, Time magazine reported. This may cause people to continue eating even if they are full.

Scientists from Deakin University in Australia asked healthy people to eat the same food for lunch for four weeks. The amount of salt in the food was changed each week. At the same time, the scientists measured how much these people ate. They also asked the people how they felt about the meals; for example, if they felt happy or were still hungry after eating.

The results showed that salt made people eat 11 percent more food and calories. When eating low-salt meals, they could control (控制) over how much they ate. “But when we add salt to that food, all of a sudden those controls are gone,” researcher Russell Keast said to Time.

Many facts suggest that children are overweight and the situation is getting worse, according to the doctors.     1    

Some people blame (责备) the fact that we are surrounded (包围) by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices.     2    

There is another argument that blames parents for allowing their children to become overweight.     3     Because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food or they are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

There is a third reason for this situation.     4     They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime, it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.

The above are the main reasons for this problem.     5     Besides, adults should keep them away from fast food shops and bad eating habits.

A．Children these days take very little exercise.

B．So we have to encourage young people to be more active.

C．If there were fewer of these restaurants, then probably children would buy less take-away food.

D．I agree with this.

E．It’s a good idea to allow children to eat what they choose.

F．I feel there are a number of reasons for this.
