In the modern age, human society runs on energy. Most machines need electricity to operate. Humans cannot live without electricity even a single day in their daily life and work. They have many different ways to create electricity. But some ways are harmful to the environment.

For example, fossil fuels (化石燃料) are the most common kind of energy.They include coal, oil, and natural gas. First, people have to dig them from the ground. This can sometimes harm the environment. However, scientists are creating cleaner and better ways to do that these days. So the environment is not harmed as much as before. But when people burn these fossil fuels, they can give off a lot of harmful gases, which is considered to be one of the greatest causes of global warning. This might harm the environment.

Tidal (潮汐) energy is another way to make electricity. This uses the ocean tides to make electricity. But some kinds of tidal energy can kill many fish and other sea animals. Also dams (大坝) can create lots of clean energy. But dams create lakes and change the way that rivers run. So they can do great harm to the balance of nature around the lakes and along the rivers.

Nuclear (核) energy is a very powerful form of energy. It is cheap. It is also very clean. But many people are afraid of it because it uses radioactive materials. Also, there have been some very serious accidents in the past which caused great harm to human and nature. But the technology is much better these days. so many countries are starting to use nuclear energy more.

1.In Paragraph I the underlined part “human society runs on energy” means “______”.

A.humans in the society waste much energy B.people use energy to make the world work

C.our society is full of varied kinds of energy D.humans cannot run fast without energy

2.According to the passage, which of the following is TRUE about fossil fuels?

A.They are dug from the ground. B.They are considered expensive.

C.They hardly harm the environment. D.They are not widely used in the world

3.From the passage, we know that tidal energy can ______.

A.cause serious accidents B.change the way that rivers run

C.give off a lot of harmful gases D.kill many living things in the ocean

4.Many countries start to use nuclear energy more because ______.

A.it’s a common kind of energy B.people are not afraid of it now

C.it’s cheap, clean and safer than before D.people can’t live without it

5.The passage is probably in the part of ______ in a newspaper.

A.health B.science C.culture D.sports

We are now living in the modern society. Most of the energy we use for heating, lighting, transportation and manufacturing (制造业) comes from fossil (化石) fuels. These are carbon-based fuels from oil, coal and natural gas. When we burn these fuels we release heat which p__1.___ the energy.

There are three main disadvantages to using these fuels. Firstly, they are causing climate problems because of the G_2.___ Effect. When we burn fossil fuels they produce carbon dioxide which causes global warming. Secondly, when we have used up all our coal, oil and natural gas, we will have n__3.__ left to burn. Thirdly, they are not very efficient. The internal combustion engine (内燃机) that we use in most cars, trucks and buses, for example, is only about 14% efficient.

Scientists are working on another fuel—hydrogen. There are a couple of advantages to using hydrogen as a fuel. Firstly, because two-thirds of the e__4.__ surface is water and water is made of hydrogen and oxygen. There is an almost unlimited supply of hydrogen. Secondly, burning hydrogen does not cause global warming. Thirdly, it is much more efficient than carbon-based fuels.

Unfortunately there are problems with hydrogen at the present time: there is the problem of separating (分离) it from water c_5.___, and there is the difficulty of storing it. It can be stored under pressure but high pressure tanks are far from safe. It can also be stored as a liquid but only at extremely low temperatures. It seems likely, therefore, that there will have to be a completely new technology before hydrogen replaces fossil fuels. S__6.___ these problems is an urgent (急迫的) matter. Although China, India and Australia have huge amounts of cheap coal, and there are still l__7.___ oil and gas reserves(储藏量) elsewhere, the effects on the planet’s climate will be bad if they are used.

Energy is very important in modern life. People use energy to run machines, heat and cool their homes, cook, get light, and transport people and products from place to place. Most energy comes from fossil（化石）fuels--petroleum, coal and natural gas. However, burning fossil fuels cause pollution. Also if we don't find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be?

Energy from the wind

All over the world, people use the power of the wind. It turns windmills and moves sail-boats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy.

Energy from water

When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40000 people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive.

Energy from the earth

There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world.

Energy from the sun

Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy.

1.What does this passage mainly talk about?

A. Advantages of the energy from nature.

B. The future of energy.

C. Scientists have been working hard to research other kinds of energy.

D. scientists have found other kinds of energy for future

3.What is the writer's opinion about the energy?

A. Try to use water energy more though it costs a lot.

B. Each natural energy has its own advantages and disadvantages.

C. Solar power is environmental.

D. Wind power is the cheapest but we can't get enough.

4.The writer suggests in the passage that ________.

A. in the 21st century fossil fuels may be used up

B. the new sources of energy will change in the next twenty years

C. if we dig deep enough, in the earth, we find geothermal energy everywhere

D. French and American are more interested in water and heat energy

The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?

The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.

The energy in food is in the form of three kinds of chemical materials—carbohydrate（碳水化合物）, protein（蛋白质） and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.

(P= protein      C= carbohydrate    F=fat)

1.How many calories are needed to raise the temperature of 5kg of water from 35℃ to 90℃?

2.Which of the following contains the most amount of calories?

3.Who needs the most amount of calories each day?

4.Which of following is True?　　

5.This passage mainly tells us ______.

Running two miles on the playground isn’t a fun thing to do for most students. But students in Miss Brown’s class at Mark Twain School in the USA gladly put on their running shoes. They wanted to raise money to help a dog in need.

Miss Brown told her students about Peter, a dog who had a hard start in life. At less than a year old, Peter’s owners found out that he was not healthy. Something was wrong with his body. Medicine could help but it was very expensive. For Peter to have a better life, he needed surgery (外科手术). But his owners couldn’t afford that. Finally, they had to leave Peter at the animal hospital.

“I love dogs and when I hear about Peter, I felt so sad for him,” says student Tony.

Miss Brown’s class decided to hold a Jog-a-Thon to raise money for Peter’s surgery.

“At first I felt like the Jog-a-Thon was just to get us to exercise,” says Mike “but then I wanted to help this dog.”

“I just wanted to make a difference in Peter’s life,” adds student Chance Wood.

News of the Jog-a-Thon spread throughout the school. Before long, five other classes also took part in the event. “I started receiving money from all kinds of people in our school community,” says Miss Brown. “We raised $3,180.64 in all.”

Chinese TV shows that describe young people's lives in modern society are crossing the cultural divide and attracting a lot of foreign audiences.

One of the examples is the Chinese TV series "A Beautiful Daughter-in-law Era", a light comedy about a modern Chinese couple.

The TV series was first aired in Shanghai in November 2009. It was dubbed in Swahili and broadcast in east African countries in 2011. Two Kenyan（肯尼亚人） actresses were chosen to do voice dubbing for the two leading roles in the African version of the series. It was a great success in Africa.

Tanzanians（坦桑尼亚人） say that they are able to understand how young Chinese people live happily in modern times and they may be able to find ways to solve their personal problems by watching the series.

Although China is one of the world's most prolific（多产的） producers of TV series, its series are not particularly popular overseas. The popularity of "A Beautiful Daughter-In-Law Era" may serve as an example for Chinese TV producers who want to bring their work to other countries.

In recent years, some TV series that show the lives of people in Chinese cities have achieved some success in the foreign market.

"Go Lala Go!," a TV series that details the adventures of a female office worker named Du Lala, has also started to reach global audiences. The series has been exported to Singapore, Malaysia, the United States and Canada.

"The Chinese dream will be more easily accepted by foreign audiences when it is manifested in small and touching stories," said Meng Jian, a professor at Fudan University.

请阅读一篇短文，根据所提供的信息，完成下面的表格。

In the modern society, the traffic problem has become more and more serious, which has aroused(引起) wide public concern（关心）, especially in the rush hour , at some time or other, people would rather walk on the street than drive the car, and the line people waiting for the bus can be as long as 10 meters. Because a great number of office workers go to work and go off work at the same time, most private cars and buses are on the roads at the same time, which of course leads to traffic jams(交通堵塞).

But how to solve it? As far as I’m concerned, for one thing, the government should build more roads to meet the needs of cars; for another, we should call for people to take a bus instead of driving their own cars. At times, we can also ride bikes to go to work or visit somewhere. Not only do we strengthen ourselves in this way, but also we protect the environment. In a word ,if all of us take actions to solve it, I believe there will not be a word named traffic jam .
