Qi Haoran, a Junior 1 student, was quite busy over the past winter holiday and not just with homework. Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign (“光盘行动”).
These students went to many restaurants and told people that saving food is important. “Excuse me, do you know that 950 million people around the world still don’t have enough food to eat? Please don’t waste(浪费) food.” They would say this kind of thing hundreds of times every day.

Luckily, the campaign has got a lot of support. In a restaurant in Xinjiang, the owner give the guests who have eaten up all that they ordered a sticker (贴花). People can enjoy a free meal when they have 10 stickers. More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers (剩饭剩菜) home.
To reduce food waste is a big task, and it needs time. It’s important that everyone does a little, just like Qi. Did you finish your meals today?

Many of us don’t know that eye care(眼护理) is important. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place.
There are several causes(原因) leading to poor eyesight(视力) like not enough food, genes(基因) and aging(老化). Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful(有害的) things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eye-sight from UV rays.
Eating healthy foods will do good to your eyesight. Remember that vitamin A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly(有规律的) and eats the right kind of food, his eyes will stay in good condition(状况) for a long time.
