【題目】 I’m the engine that keeps you working, and I’m here to share some of my secrets. I have 100 billion nerve cells(神經(jīng)細胞), so you need to consider before you blame(責怪) me for not being so fast enough. It’s not really my fault: information travels through me too fast and sometimes I can’t keep all of it.
The Internet is making me weak. A study found that you’ve been relying more on the Internet. That means I’m going to forget more over time. Scientists have been worried that our ability to think is being lost.
In general, I’m about ten percent larger in men than women. It doesn’t make men smarter. It just lets me control their different bodies. Actually, it’s more common for women to get angry, but men can’t focus on a thing well. They usually have language difficulties.
Your mobile phone scares me. A new study showed that more than one hour of mobile phone use can get me in trouble. Mobile phone radiation(輻射) might cause me to be in a worse situation.
Some parts of me never sleep. It’s important for you to get a good night’s sleep. Sleep helps to improve memories. In fact, when you are asleep, some parts of me are still working hard on my duty. Besides, laughter is really the best medicine for me. So remember to laugh more for my better situation.
【1】What’s the result of depending too much on the Internet?
A.It will make people remember things for a long time.
B.It helps people to remember things more easily.
C.It may influence one’s way of thinking.
D.It may make us have the ability to learn.
【2】Why can’t I keep all the information?
A.Because there is too much information.
B.Because information travels too fast.
C.Because I can hardly work.
D.Because I am lazy.
【3】What can you do to make “me” work better?
A.Get a shorter sleep every night.
B.Blame “me” for not being fast enough.
C.Use “me” more instead of the Internet.
D.Use a mobile phone for one hour each day.
【4】What can we know from the passage?
A.Men can pay close attention to a thing.
B.At night, “I” can completely sleep and stop working.
C.It’s clear that “I” should take medicine to work better.
D.Mobile phone radiation may bring serious problems to “me”.
