Leaves are the world’s food factories. Plants take water from the ground through their roots and take CO2 from the air. Plants use sunlight to turn water and CO2into glucose(葡萄糖), a kind of sugar. Plants use it as food for energy and growing.

A chemical called“chlorophyll”in the leaves gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.

During winter, there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories. As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves.

The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples, sunlight and the cool nights of autumn turn the glucose in the leaves into a red colour. And we can enjoy the beautiful red leaves during autumn.

If you are in Shanghai and want to throw a cup of milk tea, be careful. You need to follow these steps: first, pour out any leftover( 殘留物) into a wet waste bin; second, put the paper wrapper into a recyclable waste bin; finally, throw the single-use cup and straw(吸管) into a dry waste bin.

Sound complex( 復(fù) 雜 的 ) ？ You’ll have to get used to it. From July 1st,2019 on, people in Shanghai are required to sort(將…..分類) their garbage（垃圾） according to strict rules. Garbage is divided into wet garbage, toxic( 有 毒 的 )garbage and recyclable garbage. Many other cities in China are planning to create similar sorting 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 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, while wet garbage can be used to make gas, heat and fertilizer(肥料). But in order to recycle efficiently(有效地), we need to sort our garbage.

Can't garbage-processing companies do the sorting job for us? 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 troublesome task of sorting might encourage people to produce less waste. Do you still want to buy that milk tea?

In real life, robots are mainly used in factories. They do some dangerous and difficult jobs for humans.

Robots also helpdisabledpeople, for example, blind people. Today many blind people have a guide dog to help them. In the future, guide dogs might be robot dogs.

One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner’s walk. The owner wears a special belt (帶子). This belt sends instructions to the owner from the dog, such as “Stop here”, “Turn left” or “Turn right”.

In the United States, another kind of robot helps disabled people to take care of themselves in their daily life. The robot hears the sound of its owner’s voice. It follows instructions such as “Turn the page” or “Make a cup of coffee”.

Robots are also used in American hospitals. They can do simple jobs. At one hospital, for example, a robot takes meals from the kitchen to patients’ rooms. It never gets lost because this robot has a map of the hospital in its computer memory.

Though robots can help people in many different ways, they will never take the place of humans.
