     Women have been making scientific discoveries since ancient times. Twelve women have won the Nobel

Prize for science, one of the highest honors in the world. Some women scientists never married, some worked with the ir husbands, and othe rs raised large families. It has been difficult for women to be successful scientists.

     In the early 1800s in England, Mary Anning became one of the first women recognized for her discoveries

about the ancient history of the earth. Mary and her fathe r collected fossils (化石) in the ir village on the south

coast of Great Britain. Fossils are parts of plants or animals that have been saved in rocks for millions of years.

     When she was only twelve years old, Mary became the first person to find the almost complete skeletons

(骨架) of several animals that no longer existed on earth. She didn't become famous for her discoveries at that

time because she often sold her fossils to get money to support her family.

     In 1891, a young Polish woman named Marie Sklodowska traveled to Paris to study physics. She did so

because she could not get a college education in Poland. She began working in the laboratory of a man named

Pierre Curie. Marie and Pierre Curie got married and made many discoveries together. the y received the

Nobel Prize for Physics in 1903 along with anothe r scientist. Marie Curie became the first person to be

awarded a second Nobel Prize in 1911, this time for Chemistry. Marie Curie was one of the few women at the

time who became famous as a scientist.

1. the author believes that women scientists ______.

A. have more opportunities to become successful

B. can not get the highest honors in the world

C. go through difficulties to be successful

D. had better pay more attention to the ir families

2. Mary Anning was one of the first women to ______.

A. win the Nobel Prize for Science after getting married

B. make achievements in the study of ancient Earth

C. research animals and the ir bones

D. study the mystery of all kinds of plants

3. Mary Anning failed to be famous for her discoveries of fossils when she was 12 because ______.

A. nobody recognized them

B. the y weren't worth studying

C. she didn't want to be known to anyone

D. she sold the m for money

4. What can we learn about Mary Sklodowska?

A. She studied physics in Poland and got a college education.

B. She received the Nobel Prize for Physics in 1903 on her own.

C. She only got one Nobel Prize during her lifetime.

D. She made many discoveries after she got married.

5. What's the passage mainly about?

A. Ancient discoveries.

B. Women scientists.

C. Successful marriages.

D. Different prizes.

     Many people think it is safe to use a cell phone while they are driving. Yet Scores of studies
suggest that real multitaskers - those who can carry out multiple (多个的) tasks equally well,
make up just 2 per cent of the population. More surprisingly, the so-called "supertaskers" actually
have differently structured brains to the other 98 percent.
     The brain areas that make supertaskers differ from the rest of the population are the same parts
that are most different between humans and nonhuman primates (灵长类), according to David
Strayer, director of the applied cognition lab at the University of Utah. Scientists are unsure of the
reason why some brains are different. In fact, we could all benefit from doing just one task at once.
     In most of us, scientists have located a "bottleneck in the brain" that may explain why we find it
hard to do two things at once.
     The problem appears to be caused by a logjam of nerve messages. Faced with two almost
simultaneous (同时的) tasks less than 300 milliseconds apart, the brain's ability to deal with the
second one slows down. The neural (神经的) response to the second task was postponed until
the response to the first was completed. This means that with e-mails, phone calls, text messages
and online social media all competing for our attention, often against a background of television,
radio or music, our brains can reach information overload.
     Scientists made the discovery after scanning the brains of volunteers attempting to multitask on
a computer. The task was deliberately designed to involve the use of different senses and motor
responses.
     Dr Rene Marois, one of the neuroscientists who carried out the experiment at Vanderbilt University
in Nashville, Tennessee, said: "Our research offers neurological evidence that the brain cannot
effectively do two things at once." The next step, the neuroscientists say, is finding out "why these
areas cannot process two tasks at once."
1. How many people can drive equally well while using a cell phone?
A. Nobody.  
B. Everybody.
C. 2 in 100.  
D. 98 in 100.
2. The researchers tried to find out the difference between _____ brain structures.
A. different supertaskers'
B. supertaskers' and ordinary people's
C. humans' and nonhuman primates'
D. supertaskers' and nonhuman primates'
3. We can infer from the article that the brain takes 300 milliseconds to _____.
A. make a neural response
B. get ready for a response
C. complete a task
D. finish two tasks
4. If we _____, our brains may reach information overload.
A. serf the Internet after listening to music
B. use a cell phone against a background of television
C. complete all kinds of tasks within the same day
D. have lots of tasks queuing for responses

A. having an engine
B. relating to vehicles with engines
C. relating to nerves that make muscles move (control body movement)
D. the part of a machine that makes it move
