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.

Read the passage and fill in the blanks with proper words(在短文的空格内填入适当的词,使其内容通顺,每空格限填一词,首字母已给)

I don’t believe it! It’s 11p.m. and I’m still sitting here writing this article for the school magazine !I’ve had two weeks to write it and my teacher wants it tomorrow . She’s always c1. that I leave things to the last minute. Maybe she’s right. A month ago, I made up my mind to be more efficient this year and not to leave thing to the last minute. But I’ve failed. I’ve also been trying to get fitter for four weeks now. I’ve started going to the gym. I’ve taken up karate lessons and I’ve changed my diet. I’ve even been going to bed earlier. But I’m not feeling any fitter. I felt just a little u2.. I miss my bad habits. Why is leading a better life so hard?

I’ve just read an article on a website and I’ve found out that it isn’t my fault! In fact, it isn’t anyone’s fault! It’s our brains. They’re programmed, therefore, it is difficult to break bad habits. There’s nothing we can do . Scientists have done experiments that show we use one part of our brain when we think about o3.and another when we think about other people. However, when we think about the ‘future us’, we use the part of the brain that we usually use to think about other people. In other words, the brain sees the ‘future you’ as a different person to your ‘present you ’. And that’s why we don’t always find it easy to make sensible d4. in the future when we face difficulties.

But that’s not all. Scientists have also found out that it takes around ten weeks to form a good habit. For example , if I want to keep fit, it’s going to take me ten weeks to go to the gym and then it will become an automatic part of my life. That’s because ten weeks is the amount of time the brain needs to change and a5.new ways of behavior as a part of everyday life. The good news is that once you make it to ten weeks, everything becomes much easier. The bad news is that ten weeks is a really long time, so it’s easy to give up on (打消)your good plan s6.

So there you are. Maybe we want to change our ways and become better people but our brains won’t let us . or is this just an e7.? Look! I’ve finished my article on time. Anything is possible!
