Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census (普查) to colors of more than four thousand kinds of flowers and discovered that only eight of them are black. As we know, sunlight is formed by seven different colored lights. The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals (花瓣), are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.
1.It is _________ to see a black flower.
A.impossible B.seldom
C.common D.no chance
2.The passage tells us that ________________.
A.black flowers are so weak that it is difficult for them to grow up.
B.there is only eight black flowers in nature.
C.sunlight is formed by seven different colored lights, so the wave length of each light is different.
D.black flowers can take in the light of all the wave lengths which make them dry up because of high temperature.
3.Which of the following ideas is NOT true?
A.People have found that only a few kinds of flowers are black.
B.Flowers are easy to be harmed by very high temperature.
C.Red, orange and yellow flowers can also absorb the light of all wave lengths.
D.The black flowers cannot protect themselves from sunlight.

If we observe carefully, we van find that most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census(普查)to colours of more than four thousand kinds of flowers and discovered that only eight of them are black. Why?
As we know, sunlight is formed by seven different kinds of coloured light. The wave length of each light changes, so the quantity of heat in each light changes, too. Flowers, especially their petals(花瓣), are very delicate(纤弱) and prone(易于) to the harm caused by high temperature. Black flowers can take in all the light waves, which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.
That is why red, orange and yellow flowers are very common in nature while black flowers are so rare.
1.We can hardly find black flowers because _____.
| A．they are so weak that it’s difficult for them to grow up |
| B．there are no black flowers in the world. |
| C．the petals of black flowers are very delicate |
| D．they can take in the light of all wave lengths, which make the flowers dry up |
2. Sunlight is formed by _____.
| A．many different kinds of coloured light |
| B．three different kinds of coloured light—red, orange and yellow |
| C．seven different kinds of coloured light |
| D．four thousand kinds of coloured light |
3.The red, orange or yellow light contains _____.
| A．less heat than the other lights | B．more heat than the other lights |
| C．a great deal of heat | D．a little heat |
4.“It is a chance in a million” means_____________
| A．it is common | B．it is extremely rare | C．it’s lucky | D．it’s impossible |

Hummingbirds (蜂鸟) are one of nature’s most energetic fliers and the only birds to hover 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?
① Tested wings from different species of hummingbirds.
② Got resources from museums.
③ Analyzed the results and drew a conclusion.
④ Tested 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.

What color do you like best? Do you like yellow, orange and red? If you do, you must be an optimist, a leader, or an active person who enjoys life, people and excitement. Do you prefer grey and blue? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are likely to be strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists （心理学家）tell us. They have been seriously studying the meaning of color preference, and the effects that colors have on human beings. They tell us that we don’t choose our favorite color as we grow up. If you happen to love brown, you do so as soon as you open your eyes, or at least as soon as you could see clearly.
Black is depressing while light and bright colors make people not only happier but more active. A yellow room makes us feel more cheerful and more comfortable than a dark green one does, and a red dress adds warmth and cheer to sad winter days. It is a fact that factory workers work better, harder and have fewer accidents when their machines are painted orange rather than black or dark grey.
Remember, then, that if you feel low, you can always brighten your day or your life with a few colorful things. Also remember that you will know your friends (and your enemies) better when you find out what colors they like and dislike. And don’t forget that anyone can guess a lot about you when you choose a piece of handkerchief.
67. 1.According to the passage, men’s 110-meter hurdles Olympic champion and world record holder Liu Xiang is most likely to love the color ______.
| A．black | B．grey | C．green | D．brown |
68. 2.Why are machines painted orange in some factories, according to the passage?
| A．Because workers tend to prefer orange to other colors. |
| B．Because other colors are forbidden in factories. |
| C．Because less accidents happen due to the introduction of orange machines. |
| D．Because orange machines are easier to clean. |
69. 3.Which of the following statements is Not true according to the passage?
| A．It’s possible to cheer you up by enjoying some colorful pictures. |
| B．You can know your friends better through the color they like or dislike. |
| C．Some people are born with their colorful preference. |

The number of people who killed themselves on that bridge used to be larger than on any other bridge in the area -- until it was repainted green.
