Colors are really made by deflected (反射) light. We see color because most of the things reflect light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.
Some of the light is reflected and some is taken in (吸引) and turned into (变成) heat (热能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.
1. When something reflects light, we can _____.
A.see its color | B.see its heat | C.not see its color | D.see nothing |
A.some light | B.no light | C.all light | D.most light |
A.more light | B.less light | C.more color | D.less color |

【推荐2】Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition (眼睛识别) program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology (技术) will take the place of all other ways of finding out who people are.
However, scientists are also working on other systems (系统). Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct at present. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.
In the future your computer will be looking at you in the eye. So smile!

【推荐3】Welcome to the new Hong Kong Sleeping Bus Tour that helps you catch up on sleep.
The bus tour is a five-hour ride around Hong Kong on a double-decker (双层) bus. The bus stops at places like the city’s Lantau Island and the airport, where passengers can get off and take photos.
So how did the idea of the tour grow? “When we were trying to develop new tours, I saw a post from my friend saying that he was stressed out by his work, and that he couldn’t sleep at night,” said Kenneth Kong, the organizer of the bus tour. “But when he was traveling on the bus, he could sleep well. His post inspired (赋予灵感) us to create this tour.”
Tickets for the first Sleeping Bus Tour quickly sold out, and for $13 to $51 a ticket, riders can choose seats on the upper or lower deck.
Some passengers came prepared, bringing their own blankets and changing their shoes to slippers, while others brought travel pillows (枕头). Passengers were also given an eye mask and earplugs for a more comfortable sleep.
Dr. Shirley Li, who researches sleep at the University of Hong Kong, said, “People in Hong Kong don’t have enough time to sleep. They may tend to connect public transport with their sleep. And that’s why they found it easier to fall asleep on the bus.”
1. We can infer that Kenneth Kong’s friend ________.A.felt relaxed at work | B.had no trouble sleeping at night |
C.gave advice on creating the bus tour | D.wrote a post and inspired Kenneth Kong |

【推荐1】The Lantern Festival, also known as Yuanxiao Festival, is a Chinese festival with a long history. It falls on the fifteenth day of the first month of the lunar year. How do you usually celebrate it? Some of you might go to the Yuyuan Garden Lantern Fair in Shanghai. This year, the Nine-Turn Bridge was lined with lanterns of the dragon and its animal friends. It was crowded with people. Everyone wanted to take pictures.
Do you know how these colorful lanterns are made? He Weifu has the answer. He is a skilled lantern maker in Shanghai. To make a lantern, he first straightens some iron wires (铁丝) and covers them with colored paper. Then, he uses them to make the skeleton (骨架) for an animal lantern. This, according to He, is the most difficult step. He often spends a long time studying the animal. After making the skeleton, He puts paste (襁糊) on silk cloth to stiffen (使变得硬挺) it. The last step is to glue the cloth on the skeleton and draw patterns (图案).
He’s family has been making lanterns for 100 years. His grandfather, He Keming, was the “King of Lanterns” in the Jiangnan area. He started making lanterns at the age of 13. One day, he went to see a Lantern Festival show. A dragon lantern caught the boy’s eye. He looked at it carefully and tried to make one for himself. He practiced this craft all his life. His lanterns were very popular. Some of them were given as national gifts to visitors from other countries.
Which lantern at this year’s Yuyuan Garden Lantern Fair do you like the best? While you look at it next time, why not try to learn more about the craft of lantern making? Think about how you can help to keep this cultural heritage alive.

The internet is many different networks(网络)around the world. A network is a group of computers put together. These networks joined together are called the Internet.
Maybe that doesn’t sound interesting. But when we’ve joined the Internet, there are lots of things we can do. We can have a lot of interest on the World Wide Web (WWW).
We can use the Internet instead of a library to find all kinds of information for our homework. We can find information about our favorite sports or film stars and do some shopping on the Internet. We can also send messages to other people by email. It is much cheaper and quicker than calling our friends or sending letters.

Monarch butterflies(帝王蝶) from the eastern part of North America make the most amazing journey in the insect world. Each year, this tiny creature(生物) travels up to 3,000 miles(4,800 kilometers) to its winter home in central Mexico(墨西哥). How can it fly so far? And what is the purpose of its long and dangerous trip? Scientists still don’t have an explanation.
The length of the butterflies’ trip is only one part of the mystery. The other amazing thing is that the butterflies always return to the same place in central Mexico. How do the butterflies find their way back to the same place? This is an interesting question because only every fourth generation(代) makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.
Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation of Monarchs is born in the south in late April. It slowly moves north, reproduces, and then dies. On the trip north, two more generations are born, reproduce, and die. Each of these generations of butterflies lives for only two to five weeks. In the fall, the fourth generation of butterflies is born. Compared to its parents, this generation has a long life. It lives for about eight months. This generation of butterflies makes the amazing journey to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their children will be the first generation of the next circle. How amazing it is!

【推荐2】The Oil Lamp and the Lighthouse
On an island off the coast of a rocky shore stood a great lighthouse. During the day, the white walls of the lighthouse shined under the sunlight, while at night it burned a light for those at sea. Many people visited the lighthouse, and when they did, they commented on its size and strength and admired the beauty that it added to the surroundings. Some told its keeper how its light had saved them during a storm.
All loved the lighthouse except a little oil lamp that lived in the lighthouse. By day it hung forgotten at the bottom of the stairs. At dusk it helped the keeper of the lighthouse make his way from the bottom of the stairs to his bedroom. It seemed to the oil lamp that he is not important. To his way of thinking, his shortcomings were made clear by his nearness to one so much greater than he. Always, the oil lamp labored under this heaviness of heart.
Then one day, after a brilliant afternoon when many visitors had come to play on the sandy beach, there was a knock at the door. It was a boy, searching for a friend who was lost. The sun had set and what had seemed such friendly shores hours before was now dark and cold.
The keeper quickly took the youth inside and hugged him into a blanket. Then he reached to the hook between the door and the stairs and took down the little oil lamp. After carefully making sure that the tank was full of oil, the keeper lit the lamp and whispered. “Burn bright tonight, my dear friend. I cannot take the lighthouse with me. He serves his purpose here, but you were made for times like this. It is now that I need you most!”
In that instant, all of the oil lamp’s misgivings were replaced by joy—joy in knowing that here was something only he could do. All through the night, through bushes, the oil lamp burned brighter and more steadily than ever before. He had to; the keeper was depending on him. At last the lost boy was found and brought safely back to the lighthouse and his friend.
Never again did the oil lamp doubt his place or purpose. He had learned a great lesson that night: he was happiest and most useful being himself.
