If you are in Shanghai and want to throw away a cup of milk tea, be careful. You need to follow these steps: first, pour out any leftover(残留物）into a wet waste bin; second, put the paper wrapper(包装材料)into a recyclable waste bin; third, throw the single-use cup into a dry waste bin.
Sound difficult? You'll have to get used to it. From July lst, people in Shanghai are required to sort(分类)their garbage according to strict rules.
Why should we sort our garbage? The answer lies in the increasing amount of waste we are producing. Chinese cities produce over 200 million tons of waste each year, according to China Economic Net. Most of this waste is buried in landfills, which may pollute the water and soil. Moreover, we are running out of space for new landfills.
In fact, more than half of our waste can be recycled. Recyclable garbage can be made into new materials. For example, wet garbage can be used to make gas, heat and many other kinds of useful things. But in order to recycle garbage efficiently（有效地）, we need to sort our garbage.
Can't garbage-processing companies do the sorting job? They can. But that requires a lot of work and costs lots of money. Things will become much easier if each of us can sort our own garbage. Besides, the difficult task of sorting might encourage people to produce less waste. Do you still want to buy that milk tea?

Succulents(多肉植物) are booming in popularity for two simple reasons: they are beautiful and easy to grow. You can plant succulents in containers or in the garden, but either way, take care to make sure your plants are healthy. Here are some general rules.
Get the pots ready. Succulents need pots that will house the plant comfortably. The actual pot size will depend on the size of the plant. You need to repot(移盆) them later. If you keep it in a smaller pot, it will generally stick to that size. You’d best choose clay (陶土) pots. There should be 3 or more holes at the bottom of the pot.
Prepare your soil. Don’t use regular potting soil because it will hold onto too much water that may cause your succulents to rot. A well-drained soil is a must. Succulents tolerate dry conditions and poorer soils.
Give them some light. Succulents prefer bright light; therefore, place the pots in an area where there is plenty of sunlight, direct or indirect. Succulents need at least four hours of direct light each day. Don’t expose your succulents to hot summer sun for too long.
Water your plant. One of the common mistakes made with succulents is overwatering. If you overwater your succulents, they aren’t going to survive. It’s the same with simply spraying them lightly. The best way to water succulents is the “soak and dry” method. Basically, you need to give your succulents enough water so that the soil gets completely wet. Then, let it dry out completely before you water again. Once every couple of weeks is generally enough during the warmer months. Over winter they don’t really need water at all.
Feed your succulents during the plants’ active growing season. Some grow actively in summer while others are winter plants. Stop fertilizing(施肥) when plant growth naturally slows.
