①Water plays an important role in keeping you healthy. It keeps your body work properly. But do you know that too much water can poison (使……中毒) you?
②Water poisoning happens when people drink too much water. This lowers the level of sodium (钠) in their blood to dangerous levels.
③You probably already know that high levels of sodium can be unhealthy. That’s true. But low levels are also harmful. When you have too little sodium in your body, your cells (细胞) begin to swell (膨胀). As a result, a lot of things will go seriously wrong in your body.
④Your brain may begin to swell. You may get a headache, feel very tired and want to throw up (呕吐). You may even lose consciousness (知觉). In these situations, water poisoning can make you dead.
⑤Protecting 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 40 kilometers, you may have to drink a lot of water. Then, it is important to balance (平衡) the amount of water you drink with the amount of water your body is losing. This can help you stay healthy whenever you are exercising.
⑥So how much water should a person drink each day? In fact, the actual amount needed is different for each person. Today, most doctors are telling people that they should drink water whenever they feel thirsty.
⑦We can’t live without water. Neither can we live with too much water in our bodies. Make sure you take the right amount of it each day—staying healthy is all about staying balanced.

【推荐3】Why do we cook food? Well, we didn’t have to cook food before people discovered fire, just like wild animals do. The strange thing is, even after fire was discovered, that no one realized that they could use it to cook! They built fire mainly to scare away (吓跑) wild animals.
Some scientists think that one day, someone must have dropped a bit of meat or fish in the fire. After a while they noticed how good it smelled, tasted it and realised the heat had made it much more enjoyable to eat. Cooking was born, and finally everyone was doing it because it has three very important effects (效果) on our food.
First, it makes a lot of raw, hard food softer and easier to eat. Take a potato, for example. It starts off as a solid part but cooking can turn it into soft potato.
Second, it makes our food safer to eat. Sometimes food has microbes (微生物) that could make us ill. However, most of these microbes don’t like really hot temperature. Cooking kills them, so they can’t make us sick.
Third, and this is the most exciting effect for a cook like me cooking can change food into something that looks, smells and tastes wonderful.

【推荐1】The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories (卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows.
| CALORIES NEEDED PER DAY | |
| Baby 750 | Office worker 2,700 |
| Child aged 8 2,100 | Woman feeding baby 2,700 |
| Man over 70 2,100 | Boy aged 16 3,000 |
| Woman 3,600 | Farmer 2,600 |
Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on. The energy in food is in the form of three kinds of chemical materials-carbohydrate (碳水化合物), protein (蛋白质) and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein C= carbohydrate F=fat)

【推荐3】When we see well, we do not think about our eyes very often. It is only when we cannot see clearly that we realize how important our eyes are. However, we are supposed to care for our eyes even if we can see well.
People who are near-sighted can only see things that are close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing and reading become near-sighted. People who are far-sighted suffer from（遭受）just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses too.
Other people do not see clearly because of cataracts（白内障）. Their eyes become cloudy, and this, in most cases, can never be corrected by glasses. Long ago, these people often became blind. Now, however, it is possible for doctors to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a different angle（角度）. You can have a try-look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.
