The low percentage of women in science ，technology，engineering，and mathematics(STEM) careers is often attributed (归因于) to men being believed to be better at the sort of thinking those fields require. Though studies have debunked the view,they have largely been based on results acquired from various several standardized tests. Now, researchers from Pennsylvania' S Carnegie Mellon University have found evidence that is hard to overlook; MRI (磁共振成像) proves that young girls and boys use the same mechanisms and networks in the brain to solve math problems.

The groundbreaking study to evaluate the biological gender differences in the math talent of young children was led by the university' s professor of neuroscience, Jessica Cantlon. For their study ,the team selected 104 young children, between 3 and 10 years old, divided almost equally by gender. The scientists used a functional MRI to observe their brain activity as they engaged in math tasks. These included watching age appropriate educational videos and doing math exercises such as counting and addition,as well as reading for comparison.

“We looked at which areas of the brain respond more strongly to mathematics content in the videos and tasks, compared to non math content like reading or the alphabet, Cantlon said.“When we do that in lite girls, we see a particular network of the brain respond,and when we do that same analysis in boys, we see the exact same regions.”

So why do girls and young women tend to avoid math and STEM careers in general? Cantlon thinks it may be rooted in social and cultural conventions. Previous studies have indicated that parents tend to spend more time with young boys in play that inspire spatial cognition (空间认知)-such as toys that involve learning number skills and shapes and solving puzzles. Educators were also observed to spend more time with boys during math class.

1.What does the underlined word“debunked” in paragraph 1 mean?

The early lack of exposure to science ，technology，engineering and mathematics (STEM) can be harmful to achieving gender (性别）balance in these fields. It begins when we are young and continues throughout our time in high school.

While at home，girls generally don’t get to experience the level of exposure or encouragement in STEM fields that their male counterparts do. It is often subtle ，but it’s the first hurdle that faces and confuses so many women. Boys ，on the other hand, get on their path ，and are encouraged to do so， generally earlier than girls. For example ，boys are more often given science sets as toys ，which spark an interest in these subjects.

In school ₃ boys are often pushed to take the more challenging math and science classes. So if we want to attract the best and brightest minds into the fields that will advance us as a people _? a country，and a planet，we can no longer look to only half of the population. Young girls cannot possibly consider opportunities they do not know exist. If girls are not exposed to certain subject and career paths，they are highly unlikely to choose to follow them in college.

Our bias(偏见)toward girls₉ either from families or from schools ，is so rooted in our culture that we often don’t even recognize it. Although the situation Has changed greatly in the past 20 or 30 years，there is still a sense that girls aren't as good at math ₉ for instance ₉ even though there is almost no evidence to support such a belief.

It is important that as a society we deal with gender stereotypes long before young people are faced with a decision to declare or choose a major in college. Without making efforts to break them， we are limiting the potentials of our youth，both male and female. Providing the necessary resources， exposure _, and encouragement would help young women understand that their gender shouldn^’t determine the career path they choose, and that pursuing a STEM career does not make them less feminine.

1.According to the passage _? not many girls grow to enter STEM fields because______.

A．girls are not as good at STEM as boys

B．girls do not like to take science classes

C．girls get fewer chances to know about STEM

D．girls seldom survive the high pressure positions

2.The underlined word “it” in Para. 4 refers to______

A．our bias           B．our culture        C．the situation       D．a sense

3.The main purpose of the passage is to______.

A．show women’s potentials in STEM fields

B．praise women’s contributions to STEM fields

C．describe the present gender bias in STEM fields

D．call for more involvement of women in STEM fields

4.Which of the following shows the structure of the passage?

Humans’ invention of zero was vital for modern mathematics and science, but we’re not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.

Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.

Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren’t just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.

In further experiments, the researchers showed that bees’ understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators（捕食者）and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.

1.According to the trials, the researchers have found that bees ________.

A. have the same intelligence as parrots and monkeys

B. can count many numbers after being trained

C. can identify the smaller number quickly

D. understand the concept of zero

2.The researchers trained another group of bees to ________ .

A. confirm the bees are able to identify the smaller number

B. find the big difference between the two groups of bees

C. prove the bees are interested in new things

D. show the bees can be distinguished easily

3.What do the researchers suggest in further experiments?

A. Bees should be trained more.

B. Numerical abilities could help predators find bees.

C. Insects are better at understanding zero than animals.

D. Animals may display a thorough grasp of the number zero.

4.What is the best the title for the text?

A. New Findings About Bees’ Concept of Zero

B. Experients on Bees’ Numerical Skills

If maths is the language of the universe, bees may have just uttered their first words. New research suggests these busybodies of the insect world are capable of addition and subtraction (减法)—using colors in the place of plus and minus symbols.

In the animal kingdom, the ability to count—or at least distinguish between differing quantities—isn’t unusual: It has been seen in frogs, spiders, and even fish. But solving equations (方程式) using symbols is rare, so far only achieved by famously brainy animals such as chimpanzees and African grey parrots.

Building on previous research that says the social insects can count to four and understand the concept of zero, researchers wanted to test the limits of what their tiny brains can do.

Scientists trained 14 bees to link the colors blue and yellow to addition and subtraction, respectively. They placed the bees at the entrance of a Y-shaped maze (迷宫), where they were shown several shapes in either yellow or blue. If the shapes were blue, bees got a reward if they went to the end of the maze with one more blue shape (the other end had one less blue shape); if the shapes were yellow, they got a reward if they went to the end of the maze with one less yellow shape.

The testing worked the same way: Bees that “subtracted” one shape when they saw yellow, or “added” one shape when they saw blue were considered to have aced the test. The bees got the right answer 63% to 72% of the time, depending on the type of equation and the direction of the right answer—much better than random guesses would allow—the researchers report today in Science Advances.

Though the results came from just 14 bees, researchers say the advance is exciting. If a brain about 20,000 times smaller than ours can perform maths using symbols, it could pave the way to novel approaches in artificial intelligence (AI) and machine learning. Just don’t ask the bees to do your homework anytime soon.

1.Why do the scientists conduct the research?

A. To teach them maths. B. To test the power of tiny brains.

C. To explain the meaning of colors. D. To get access to machine learning.

2.What does the underlined word “aced” in Paragraph 5 probably mean?

A. Given up. B. Entered for.

C. Got through. D. Checked over.

3.What might the research make contributions to?

A. Language acquisition. B. Arithmetic learning.

C. Protection of animals. D. Development of AI.

4.What can be the best title for the text?

A. Bees “Like” Counting

B. Bees “Tell” Colors Apart

C. Bees “Perform” Maths Using Shapes

D. Bees “Get” Addition and Subtraction

Probably one of the most popular topics in science-fiction of all times has been the idea of time traveling. We know and love such films as H. G. Wells’ The Time Machine, H. P. Lovecraft ’s The Shadow Out of Time as well as a great number of films and TV shows: Back to the Future, The Butterfly Effect. These, as well as many others, are dedicated mostly to one question: how can an individual affect or even change their entire life in the present by making even slight corrections, in their own past?

When I was a child, I often dreamed about a special pocket device that would allow me to “save” certain moments of my life. In that case, if I failed to do something, I could always “load” my life. I imagined all the things I could do if I had such power : jumping from very tall buildings without a parachute ( and “loading” at the last second) and taking up other risky occupations.

Sometimes, I would like to jump into a time machine, go back to a couple of years ago, and make many corrections. I would warn myself about the consequences of my most reckless (不顾后果的) decisions. I would talk to that long-haired teen holding his first cigarette and tell him, “Don't do that — years will pass until you finally manage to quit it. ” There are so many warnings I would give to myself that sometimes I think: was it really I who did this and that?

Having a time machine is an amazingly attractive idea. It seems that having one would make life so much easier! Perhaps, it is true. But what I think more often now is that living without it teaches us responsibility. I try to live each day at the maximum in order to regret nothing. This is actually what our parents always try to do when we are children. But you know what? I am glad that no time machine has been invented.

1.What's the writer's main purpose of writing Paragraph 1?

A.To introduce some famous movies.

B.To raise a question about time travel.

C.To show those movies are very popular.

D.To show the scenes in movies might become true.

2.What does the writer try to convey in this article?

A.Unpractical dreams can never be realized.

B.What happened in the past can't be changed.

C.The idea of the time machine is really a creative invention.

D.Being responsible for the present is better than regretting.

3.What's the writer's attitude toward the invention of the time machine?

A.Objective. B.Supportive.

C.Negative. D.Indifferent.
