“Millions of young people will lose their hearing in five years if they listen to MP3 or MP4 players at a too high voice every day,” scientists say recently.
Do you often listen to MP3 players at a too high voice? Are you frightened to hear this?
The sizes of MP3 players are very small, but small MP3 players make it easy to take hundreds of songs with you. So many young people carry them and listen to music every day. MP3 players are very popular among students.
The scientists say teenagers should be far from high volume (音量), including mobile phones’ noise. A study says, “High volume and long listening time can cause hearing problems.” They think if young people listen at more than 89 decibels (分貝) every day, they will lose their hearing in five years. A scientist said, “So many young people often use personal music players and mobile phones at a high voice. I am afraid that they may be losing their hearing.
So let’s turn our MP3 players down!
小題1:According to the passage, which of the following is true?

A．Scientists tell young people to turn off their MP3 players.

B．Teenagers will lose their hearing if they listen to hundreds of songs in MP3 players.

C．A person will lose hearing in 5 years if he or she listens to an MP3 player every day.

D．The mobile phone can also cause hearing problems if we don’t use it correctly.

小題1:根據上文“So many young people……at a high voice.可知此處所說的主要是青少年，故選D。
小題1:這篇短文主要說的是高音量對聽力的危害，故選A，最符合題意。把你的MP3音量降下來。

Do you know that women’s brains are smaller than men’s? Normally the women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聰明的） than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount（數量）of “thinking” brain is almost the same in both men and women.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes（性別）. As white matter is the key to spatial（空間的）tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses（胎兒）are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
小題1:Which of the following is TRUE according to Paragraph 1?

A．Grey matter controls thinking in the brain.

B．Men’s brain is 10% less than women’s.

C．Grey matter plays the same role as white matter.

D．Men and women have the same amount of white matter.

小題2:What can you infer from Paragraphs 2 and 3?

A．Men have weaker spatial abilities.

B．Women do not need to tell directions.

C．Women prefer doing many things at a time.

D．Women do many jobs at a time better than men.

小題3:What can you learn from Paragraph 4?

A．Our children needed more spatial skills.

B．Women may have more feelings than men.

C．Young boys may be stronger than young girls.

D．More women take up jobs requiring speech skills.

小題4: The passage is mainly about _______.

A．ways of being more intelligent

B．differences between men and women

C．studies on brains between two sexes

D．studies on white matter and grey matter
