The world would be a very different place if someone hadn’t invented the lift. There would be few, if any, high-rise buildings because people would refuse to climb many stairs. By the time workers reached their offices on the top floors of a tower building, it would be time to go home – if they were not too tired for the long walk down!

The first lift that we know about was used by the Greek scientist, Archimedes, in about 230 BC. It was a simple place that could be pulled up and down with a rope. A lift like this was used much later in the 12th century by priests who lived on top of a mountain at Metereo in Greece. Because they were afraid of killers, the priests had not built any stairs up the mountain. The only way up was by lift, which priests worked from the top of the mountain.
A few hundred years later, a Frenchman, Villayer, invented a ‘flying chair’ which used a rope and a place. A number of rich people had these ‘flying chairs’ built in their homes, including Queen Anne of England in Windsor Castle and Louis XVI of France at Versailles. Unluckily, Louis’ daughter was badly hurt when using one of the chairs, and Villayer ran away, afraid that he would be punished.
The main problem for lift engineers was that either humans or animals were needed to pull the ropes. This problem was not worked out until the discovery of steam power. But even steam powered lifts were not always safe because they also used ropes which sometimes broke. If the rope broke - which it sometimes did - the lift fell to the ground and people in it were killed or hurt. This problem worked out in 1854 when an American, Elisha Otis, invented something which stopped the lift from falling if the rope broke. At first Otis lifts were used only in factories, then in 1857 he built one in a large New York store. Now lifts use electric power and are completely safe. They also travel very quickly. Some lifts travel faster than 60 kilometers an hour.
小題1:The writer thinks that lifts are important today because __________.
A.people like playing on them
B.they are the best way of using steam power
C.we need them for tall buildings
D.workers are lazy
小題2:The 12th century priests had a simple lift instead of stairs because ___________.
A.they thought the stairs were broken
B.they liked having stairs and a lift
C.the lived at the bottom of a mountain
D.they were afraid of killers

A.poor people could not afford his ‘flying chair
B.someone was hurt in one of his ‘flying chairs’
C.his ‘flying chair’ did not work at all
D.he ran away with Louis XVI’s daughter
小題4:Steam power meant that ________  .
A.they did not need a living thing to pull the ropes
B.Elisha Otis could invent a lift that would not fall
C.the rope always broke
D.they could use lifts in factories

Do you know how important it is to have breakfast? A study of 2,000 teenagers in the US showed that eating breakfast daily is helpful to young people.
According to the study, teenagers who eat breakfast weigh around 5 pounds less than teenagers who do not. Although they take in more calories (卡路里) in the morning, they are more active during the day because they have more energy. This means they burn more calories than non-breakfast eaters. The breakfast does not even have to be very healthy, as eating anything is better than nothing.
The study also showed that eating breakfast keeps teenagers feeling full for longer, so they will not eat too many snacks (零食) later in the day. This is good news as most popular snacks, like sweets and potato chips, are usually unhealthy and full of calories.
Another big advantage of eating breakfast is that it helps teenagers do better at school.This is because it gives them more energy to keep their attention in class.
What's more, a study in the UK showed that adults (成年人) who eat breakfast daily put on less weight and also perform better at work.
Whatever your age is, take time to have breakfast every day.
小題1:The underlined sentence in Paragraph 2 means that _________.
A.teenagers should eat something for breakfast

Last March, the H7N9 virus (病毒) hit Shanghai, Anhui, Jiangsu, Zhejiang and so on. It seemed that most people who were infected(被感染) with H7N9 had the common flu. Some people suffered from a fever or a cough.

Don’t be afraid—it’s not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes.
Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet, and after you touch animals, because your hands may carry viruses.
Cover your nose and mouth. When someone sneezes(打噴嚏) or coughs, flu viruses can travel as far as one meter through the air, so you’d better stand a proper distance (距離) while talking to someone who has a cold. And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your hands.
Wear a mask(口罩). Some doctors say that masks can stop the flu as much as 80%, but if
you don’t wash your hands often, it’s no use wearing a mask. And it’s necessary to wear the mask in the groups of people.
Do sports often. Exercises will help make your body strong enough to resist the virus.

Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap(捕蠅草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all these important things, especially nitrogen(氮).Animal meat has a lot of nitrogen, so some plants eat meat to get what they need.

Have you ever wondered?
Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon (大氣現(xiàn)象) known as the jet stream (氣流). The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.
What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other buildings float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Turning off’ gravity would be like letting go of the string. Things not attached to the earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling (=" top" surface of a room). Most things outside would fly off into space.
小題1:What information can we get from the first passage?
A.It is the jet stream that affects how fast airplanes fly.
B.Planes go slower when they are moving with the wind.
C.It takes more time to fly from NY to London than from London to NY.
D.The jet stream always blows from the east to the west across the Atlantic.
小題2:The underlined word “shoot” in the 2nd paragraph means “_________”.
A.send for B.move quicklyC.come out D.grow quickly
小題3:It can be known that without gravity _________.
A.buildings and other structures would float away
B.trees and buildings would not so easily fly off
C.something around your head would not float away
D.everything outside buildings would fly off into space
小題4:Which of the following is not mentioned in the passage?
A.It takes seven hours to travel from London to New York.
B.The earth is moving at a high speed.
C.Things on the earth will float away if there’s no gravity.
D.Things not attached to the earth would fly off in a straight line.
小題5:Where can we read this passage?
A.In a research paper. B.In a short story.
C.In a travel magazine.D.In a student’s book

Imagine the situation. You are driving in a village or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car doesn’t work. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is used for finding your position(位置) with the help of satellites (衛(wèi)星). A GPS can’t start your car, but at least you will know where you are.
GPS, which means Global Positioning System(全球定位系統(tǒng)), is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find a GPS in cars, planes, or boats. Some of them have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.
There are three parts to GPS. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites going around the Earth. The receiver communicates with at least four of the satellites and calculates its position. The third part of the system is a network of ground stations all over the world. They control (控制) the satellites and make sure they are working well.
Some people think that in the future the GPS will be as common as the mobile. They are becoming better and cheaper. There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.
小題1:According to the passage, with the help of the GPS, people __________.
A.can’t be lost in a new city
B.can’t find their way in different countries
C.can learn about the culture of an unknown place
D.can spend the least time getting to another place
小題2:We can learn from the passage that ____________.
A.there are three parts to the GPS
B.a(chǎn) GPS can’t be put into a watch
C.a(chǎn) GPS can help you start your car
D.the GPS are becoming more and more expensive
小題3:The underlined word “They ” in paragraph 3 means “____________”.
A.ReceiversB.GPSC.SatellitesD.Ground stations
小題4:What can we infer(推斷) from the passage?
A.All GPS devices have electronic maps.
B.People in many countries will use the GPS for free.
C.The receiver of the GPS communicates with at least five of the satellites.
D.The GPS will become more and more common in everyday life.
