Do you know about bio-plastic（生物塑料）？It is a kind of plastic. but it is not the same as normal plastic. Normal plastic is made from chemical materials and takes a very long time to degrade（降解）. But bio-plastic is good for the environment. it is made by using bacteria（细菌） to process（加工）natural sources like vegetable oils, corn or sugar. It can degrade more easily.

But there is a problem with bio-plastic. The "food" that bacteria eat is what we eat. This means that bacteria are competing against humans for the same resources.

Now scientists have found a new way to make bio-plastic－using two kinds of bacteria and sunlight. According to Newsweek.

One of the bacteria can use sunlight to produce sugar. The other land eats the sugar and produces polymers(聚合物）. Polymers are used to create bio-plastics. The way the bacteria store polymers is similar as humans store fats.

The new way to produce bio-plastic has many advantages. It is 20 times faster than the normal way we produce bio-plastic. Moreover, using these two bacteria saves resources.

The next problem scientists face is that they want to put their tab research into real-world practice. By doing this, bio-plastic made with these two bacteria can be widely produced in the future.

1.According to the passage, which is TRUE about bio-plastic?

A.It is bad for the environment.

B.It's made from chemical materials.

C.It is a new kind of bacteria.

D.It can degrade more easily.

2.What does the phrase "The food" underlined refer to?

A.Normal plastic. B.Normal bacteria. C.Salty waters. D.Natural sources.

3.From the passage, which is the correct order to make bio-plastic?

a. eating the sugar

b. creating bio-plastics

c. producing polymers

d. using sunlight to produce sugar

A.a-d-c-b B.a-d-b-c C.d-a-c-b D.d-c-a-b

4.What's the main idea of the passage?

A.A new kind of plastic. B.A new way to produce bio-plastic.

C.A way to store fats D.A way to produce two kinds of bacteria.
