2 . When it comes to becoming eco-conscious (有生态意识的), many people choose to start with something simple: recycling (回收利用). But it’s not as simple as everyone seems to believe.

Indeed, the desire for some people to recycle can lead to ill-informed (不了解情况的) decisions about what can and cannot be recycled, and non-recyclable objects are accidentally put into the recycling bin. The practice is what is known as wishcycling.

Wishcycling boils down to (归结起来是) the idea that just about anything can be recycled, and that if you put it into a recycling bin, those who are responsible (负责的) for it will find a way to recycle it. This is obviously not true, because, despite everything that you’ve been told by the media, not everything is recyclable.

Small non-recyclable objects that are attached to recyclables are generally acceptable. For example, glue and tape attached to paper will be removed in the recycling process without any trouble. But improperly recycling broken eyeglasses, plastic shopping bags, food waste and greasy (沾油渍的) pizza boxes could cause problems to the recycling process.

The objects in the recycling bin are typically sorted by machines at recycling centers, not people. These complex machines are designed to separate plastics, paper, and other recyclables. If something is thrown into the bin that shouldn’t be there, it could end up damaging the machine, which means the recycling center could lose time and money every time people decide to wishcycle. Sometimes, a non-recyclable object is able to sneak (溜) past these sorting machines. If this happens, the non-recyclable object ends up in a load of recyclables that will be sold for the recycling center to make a profit. However, having just one non-recyclable thing mixed in can pollute the entire load of recyclables, which has to be thrown away.

So what you as a consumer need to do is make your own recycling practice most functional (实用的). The best way is to educate yourself. There are certain general rules when it comes to recycling that everyone should know.

1. What do we know about wishcycling?

A．It is misled by the media.	B．It leads to a better ecology.
C．It is related to bad information.	D．It comes from people’s hope.

2. Which of the following can be put into the recycling bin according to the passage?

A．Paper with glue on it.	B．Only pizza boxes.
C．Plastic shopping bags.	D．Left-over food.

3. What is Paragraph 5 about?

A．The problems from wishcycling.	B．The need to update the machines.
C．The reasons for making less profit.	D．The objects unsuitable for recycling.

4. What might be talked about in the paragraph that follows?

A．Reducing waste.	B．Making rules.
C．Recycling properly.	D．Consuming wisely.

3 . Open an app at your smart phone and scan the code bar (二维码) on the garbage can. When you throw garbage into the garbage can, it will show the weight of the garbage and the points you can get from doing so.     1     It will become more popular in the future. Yes, we are talking about the smart garbage can.

    2     The environmental problems have become constant headaches in the development of the cities. Encouraging garbage classification has become an effective way.

In some cities, a variety of multifunctional smart garbage cans are being put into use. In Beijing, for example, a smart garbage can is equipped with an LED screen, which not only shows national policies on garbage classification but also shows the correct steps for garbage sorting. It can also calculate the weight of the garbage and the accumulated points one can get. They can be traded for some articles of daily use.     3     Its body is actually a screen. It is equipped with some internal sensors. When people throw garbage into it, the internal sensors can automatically tell the types of the garbage. Meanwhile, people can see how to deal with them.     4    

Garbage disposal is a small issue that involves everybody each day. However, it is also a big issue.     5     With smart garbage cans in our daily life, the idea of garbage sorting will become more established. Our dream of building a greener and more beautiful China will come true so long as we start to make small changes right now.

A．The good habit of garbage classification can improve the living environment.

B．Over 200 million tons of garbage is produced each year in some cities.

C．It will affect China’s transformation towards green development.

D．Such a way of handling garbage has appeared in some cities.

E．It is no wonder that residents cheered for their presence.

F．Another kind of garbage can is even smarter.

G．Garbage sorting has been a new fashion.
