【推荐1】Experts in nutrition(营养) suggest that we should eat at least five different kinds of vegetables and fruit a day. They are very necessary for our health and help our bodies work well. They can help reduce (减少) the risk of getting ill. There are a lot of vegetables and fruit to choose from and they taste delicious.     1    !

It’s easy to buy our food from the local supermarket, so why do we go to the trouble of growing our own? Here are several good reasons:   

First,     2    . You can pick and eat it at once. When you have tried it, you will agree that vegetables and fruit that are eaten straight taste better than anything you can buy in a supermarket.   

You may want to cut down on your “food miles”-the distance that a product has travelled before it reaches your kitchen. Many food packages are flown halfway across the earth.     3    .

Homegrown（家庭种植的）food is likely to be healthier. Food producers often use fertilizers (化肥) and pesticides (农药) which can end up in your food. If you grow your own, things are different.     4    .

You might also choose to grow some traditional vegetables and fruit. These often have more of the vitamins, minerals(矿物质) and protein(蛋白质) that keep you healthy.   

    5    . And you can grow your own even if you only have a small garden. Some food can grow well in pots, including lettuce, tomatoes, potatoes and carrots. You can recycle plastic bottles and cups to grow something. Just make sure there are holes for drainage (排水) and a small plate under them to catch drops of water.

Happy gardening!

Teeth are important to everyone. National Teeth-Loving Day is on September20. Do you know the life cycle of teeth in your mouth? Children under 6 years old have 20 baby teeth. From 6 to 13, people lose their baby teeth one by one. Now permanent teeth（恒牙）begin to grow. Between the ages of 17 and 25, some people grow wisdom teeth （智齿）. Of course, wisdom teeth don’t make you any smarter. They look like a symbol of being grown-ups（长大）.

Do you know any ways of keeping our teeth strong and healthy? Let’s look at the following tips.

What we can do:

Brush your teeth at least twice a day: in the morning and before bedtime.

Brush for at least two or three minutes every time.

Brush up and down on every tooth.

Use a dental floss（牙线）for your teeth to make them cleaner if necessary.

Get a new toothbrush every three months.

What we can’t do:

Don’t eat too much food like candies and don’t drink too much soda.

Don’t eat very hard food. That can hurt your teeth.

Don’t eat snacks before bedtime.

Healthy teeth help us eat food to let us grow. They help us speak clearly. And yes, they help us look good.
