American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.
The study, conducted by neuroscientists (神经学家)and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy. “Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals. “From the second paragraph, we can learn that ________.

One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem, while the student claimed a perfect score. I was elected as their arbiter（仲裁人）. I read the examination problem: “Show how it is possible to determine the height of a tall building with the aid of a barometer（气压计）. ”The student had answered; "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. The length of it is the height of the building.”
The student had really answered the question completely, but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and dashed off one, which read：“Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula（公式）to calculate the height of the building.”
At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others, and then added, "Probably the best is to take the barometer to the administrator and said to him, ‘Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.”,
Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.
The name of the student was Bohr who later was famous all over the world. He won the Nobel Prize for Physics in 1922.The student got a zero at the beginning because _____.
| A．the teacher wasn't satisfied with him |
| B．his answer wasn't complete or correct |
| C．the teacher didn't fully understand his answer |
| D．his answer didn't show his knowledge of physics |
We know from the passage that _____.
| A．the student knew the expected answer |
| B．the administrator told Bohr the height |
| C．the author preferred Bohr's last answer |
| D．the teacher was a very stubborn person |
We can learn from the passage that _____.
| A．instructors can teach students how to think |
| B．arbiters can help students to get high scores |
| C．students should be given more freedom in thinking |
| D．teachers should make students use physical formulas |
What was Bohr's attitude toward his schooling?
| A．Optimistic | B．Critical | C．Approving | D．Neutral |

The African elephant, which is the largest land animal remaining on earth, is of great importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna (大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.What is the passage mainly about?

Edmonton's Downtown Park is transformed into one huge stage for five days where artists are able to share their talents, and where people are able to celebrate and enjoy themselves. Since its beginning in 1980, the Edmonton Folk Music Festival has been commemorating (纪念）the true feeling of what folk music is all about and that’s the traditional togetherness (友爱）that is felt when people gather to share stories and feelings through song.
This year will be the sixth year when volunteer Riedel will be offering up her time to the festival. “People coming off a busy spring and summer have a moment of relaxation,” Riedel said. “It’s really easy to relax, and it’s great seeing family and friends have fun together.” These families and friends come from all different kinds of musical tastes. People who take pleasure in Blues are there, so are people who love Bluegrass. This festival does its best to develop everyone's musical interests.
With so many years of experience, the festival has become a well-oiled machine, and does whatever it can to make attendees feel as comfortable as possible. There are free water stations throughout the venue (举办地）for people to fill up their travel cups. When people buy food, reusable dishes are given a $2 plate fee, but that is returned when the plate is brought back.
The festival has completely sold out of tickets, and in record time. But with big names such as Van Morrison and Jakob Dylan, it’s easy to see how that was going to happen. There is no parking area during the festival, so using the Park & Ride system or Edmonton Transit is highly recommended. A bike lock-up area is provided and will be available Thursday until Sunday one hour before the gates open until 45 minutes after the gates close.

It was a dark, wet November morning. It seemed like it would take a million years to get to summer again. I thought bears have got it right---- what a perfect idea to sleep through the worst part of the year and wake up when spring comes!
“Want some words of affirmation(肯定)?” a coworker, seeing my mood, kindly suggested. “You don’t think they would cheer you up?”
“Today? No.” I shook my head.
“I used to think so too,” he said, “until I realized the effect my words had on a certain person. Well, it was someone I knew pretty well. I have to say I treated him rather badly.”
“You? But you are always so positive! How did you treat him badly?”
“I told him I did not like anything about him, really. I told him I did not even like his name. In fact, it wasn’t only what I said. I also did pretty bad things to him. When he was hungry, I did not give him the chance to eat proper food. When he felt like doing something fun, I said to him that he was being childish and having fun was not productive (有成果的). And worst of all, when he was sick and needed care, I did not care. I told him to get up and get to work. And when he did, I never told him he did good work. You could say I was ashamed of him,” he said. “I wanted to get rid of him because he just wasn’t good enough for me---but couldn’t.”
“But that was heartless!”
He nodded. “Then one day it all changed. I stood there in front of the bathroom mirror one morning. I saw the dark circles under his eyes, I saw the excess (过量的) weight. I saw the hair that needed cutting. And I saw the eyes that once had looked at the world eagerly. Now they were so sad and tired. And there and then I realized he deserved better. So I told the man I had disliked for so many years that he was a good person after all.”
My jaw (下巴) dropped. I looked at him---full of positive energy, in good shape, always ready to encourage others.
“Wow…”
