Why do we need to throw less away? There are two reasons. One is that some resources(资源)are nonrenewable(不可再生的). That means there is only a certain amount of that resource in the world. One example of these resources is oil. When we use up all the oil in the world, there will be no more.
There is a second reason for throwing less away. All of our trash has to be put somewhere. Often, it is put into garbage dumps(垃圾场). Much of that trash will be there for hundreds of years. The dumps ill be filled up with all this trash.
There are three ways to cut down on trash.
One way is to recycle. When you recycle something, it means it is made into another shape and used again. Old newspapers may become paper bags. A glassware can be melted(熔化)and made into a bottle.
Another way to cut down on trash is to reuse things. You can wash and use a bottle again that can hold mustard(芥末酱)or something else.
The third way to cut down on trash is to reduce the amount of trash you make, for example, stopping buying things that you don’t need in the first place. That reduces the amount of the earth’s resources.

A ban on smoking in most public places goes into effect(效果) on Sunday in China - home to a third of the world"s smokers. That means around 300 million smokers will no longer be allowed to light their cigarettes in the "enclosed public places." These include hotels, restaurants, theaters and public transport waiting rooms. The ban does not cover offices or factories.
The campaign is aimed at controlling(控制) the number of deaths from smoking-related illnesses, running at a million a year. According to the World Health Organization, more than 3,000 people die every day in China because of smoking. Health experts also hope it will help Chinese to raise the knowledge of the dangers of smoking.
But the new rules have been criticized because they do not include punishments(处罚) for those who choose not to obey them.Most people worry that Chinese smoking ban may have little effect.
Business owners often hate rules that force(强迫) them to ban smoking on their restaurants, bar, cafe..., because many customers(顾客) do not like the rules and complain. Often you find people smoking at the next table while you are eating your meal or having a drink in a bar.
It appears that many Chinese people don’t know the dangers of smoking. Research suggests only one in four knows the harm(害处) cigarettes or second-hand smoke can cause.

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. 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.
