Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the robot mail carrier, brings mail to a large office building in Washington, D.C. He is one of 250 robot mail carriers in the United States. Mr. Leachim, who weights two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child’s name, their parents’ names, and what each child knows and needs to know. In addition, he knows each child’s pets and hobbies. Mr. Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification (识别) number. His computer brain puts the child’s voice and number together. He identifies the child with no mistakes.
Another advantage is that Mr. Leachim is flexible. If the children need more time to do their lessons they can move switches. In this way they can repeat Mr. Leachim’s lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr. Leachim off.

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（聪明的） 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（数量）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（性别）. As white matter is the key to spatial（空间的）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（胎儿）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.
小题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.

小题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.

小题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.

小题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

People with bigger brains tend to score higher on standardized tests of intelligence, according to new study findings.
However, Dr. Michael A.McDaniel emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein’s brain was “ not particularly large,” McDaniel noted “ There’s some relationship between brain size and intelligence on average, but there’s plenty of room for exceptions,” he said.
Interest in the relationship between brain size and intelligence grew in the 1830s, when German anantomist(解剖学家)Frederick Tidemann wrote that he believed there was “ a natural connection between the size of the brain and the mental energy displayed by the individual man.” Since that statement, scientists have conducted numerous studies to determine if Tidemann’s idea was , in fact, correct. Most studies have investigated the link between head size and intelligence .More recently, however, researchers have published additional studies on intelligence and brain size, measure using MRI scans .
For his study, McDaniel analyzed more than 20 studies that investigated the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on average, people with larger brain volume tended to be more intelligent. The relationship was stronger in women that men, and adults than children ,McDaniel noted.
In an interview, McDaniel noted that he’s not sure why the relationship was stronger for adults and women. Previous research has shown that women, on average, tend to have smaller brains that men, but score just as well--- if not higher--- in tests of intelligence he said.
McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-brained people who are highly intelligent,” he said” But , on average, the relationship holds.”
73．What does the passage mainly tell us?
A．The success of using MRI scans for studies on man’s intelligence.
B．On average bigger brains mean higher IQ.
C．The importance of our brain volume.
D．Dr. Michael succeeded in his studies on man’s intelligence.
74．By mentioning Albert Einstein, the writer wanted to show ___.
A．what Albert Einstein achieved had nothing to do with his brain size
B．probably the studies on man’s intelligence are not worth believing
C．why hard working is more important than intelligence.
D．the results of thes e studies are not true for everyone
75．The underlined word “investigated “ could be replaced by ____.
A．worked our
B．guessed C．study
D．imagined
