According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate (互换). The end result is that the opposite sides of the body are controlled by the opposite sides of the brain.
The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in reading, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies.
Theory number two focuses on the asymmetrical nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left.
There is no doubt that all exist in a “right-handed society”, which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instruments for the 96%. Left-handed people make up for the unfairness by being members of an elite (精英) society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci.
1.Which of the following statements is TRUE according to the passage?
A. Left-handed people are better at speaking
B. Left-handed people are believed to have stronger left halves of the brains
C. Right-handed people are cleverer than left-handed people
D. Right-handed people work best with the right side of their bodies
2.Which of the words or phrases is closest in meaning to the word “asymmetrical”?
A. valuable B. not typical
C. not balanced D. negative
3.What can be inferred from the passage?
A. Left-handed people may feel inconvenient in this right-handed society
B. This is an equal society for the left-handed people
C. Most great geniuses are left-handed
D. Left-handed people are considered to be disabled
4. What’s the best title for the passage?
A. Which proves to be the better way to live, right-handed or left-handed?
B. How do left-handed people differ from right-handed ones?
C. Why are some people left-handed?
D. Are left-handed people equally treated in society?

It is six o’clock in the morning. You are asleep in my left arm and I am learning the art of one-handed typing. Your mother, more tired yet more happy than I’ve ever known her, is sound asleep in the room next door.
When you’re older we’ll tell you that you were born in Hong Kong in the lunar year of the pig. “It's a boy, so lucky,” our neighbours told us. They said you were the first baby to be born in the block this year. This, they told us, was good Feng Shui, in other words, a positive sign. Naturally your mother and I were only too happy to believe that.
Your coming has turned me upside down and inside out. I am pained by the memory of each suffering child I have come across on my journeys as a journalist. To tell you the truth, it’s nearly too much for me to even think of the children being hurt and abused and killed.
Last October, in Afghanistan, when you were growing inside your mother, I met Sharja, aged twelve, motherless, fatherless, guiding me through the grey ruins of her home. Everything was gone, she told me.
There is another memory of Rwanda, and the churchyard where I found a mother and her three young children huddled(蜷缩) together where they’d been beaten to death. The children had died holding on to their mother.
Daniel, these memories explain some of the protectiveness I feel for you, and the occasional moments of blind terror when I imagine anything bad happening to you.

Hummingbirds(蜂鸟) are one of nature’s most energetic fliers and the only birds to hover(盘旋) in the air by relying on their strength alone.
Now scientists have found that it is the ratio(比值) of the bird’s wing length to its width that makes them so efficient. The discovery is helping experts compete with 42 million years of natural selection to build helicopters that are increasingly efficient.
David Lentink, an assistant professor at Stanford University in California, tested wings from 12 different species of hummingbirds, which he sourced from museums. He placed them on a machine used to test the aerodynamics(气力学) of the helicopter blades(桨叶). Professor Lentink’s team used the same machine to test the blades from an advanced micro-helicopter used by the UK’s army. They found that the micro-helicopter’s blades are as efficient at hovering as the average hummingbirds.
But while the micro-helicopter’s blades kept pace with the average hummingbird wings, they could not keep up with the most efficient hummingbird’s wing. The wings of Anna’s hummingbird were found to be about 27 percent more efficient than the man-made micro- helicopter’s blades.
While Professor Lentink wasn’t surprised at nature’s superiority, he said that helicopter blades have come a long way. “The technology is at the level of an average hummingbird,” he said. “A helicopter is really the most efficient hovering device that we can build. The best hummingbirds are still better, but I think it’s amazing that we’re getting closer. It’s not easy to match their performance, but if we build better wings with better shapes, we might match hummingbirds.”
Professor Lentink said that we don’t know how hummingbirds maintain their flight in a strong wind, how they navigate(确定方向) through branches, or how they change direction so quickly. He thinks that great steps could be made by studying wing aspect ratios-the ratio of wing length to wing width. Understanding these abilities and characteristics could be a benefit for robotics and will be the focus of future experiments.
1.What did the scientists find about hummingbirds?
A. Their wings are long and wide
B. They can hover in the air for a long time
C. The ratio of their wing length to wing width is very important
D. They are the most energetic flier in nature
2.Which is the right order of Professor Lentink’s research?
①Tested wings from different species of hummingbirds
②Got resources from museums
③Analyzed the results and drew a conclusion
④Tested the blades from a micro-helicopter
A. ①②③④ B. ②①③④
C. ②④①③ D. ②①④③
3.According to Professor Lentink, what will be the focus of future experiments?
A. To know how hummingbirds can fly in a strong wind
B. To know how hummingbirds change direction so quickly
C. To develop a new kind of helicopter
D. To study the secrets of hummingbirds
