As we all know, millions of people worldwide cook their food over smoky fire every day. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun.

Solar cooker, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in seventeen sixty-seven. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.

There are three kinds of solar ovens. The first is a box cooker, It is designed with a special wall that shines or reflects sunlight into the box .Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food.

The second kind of solar oven is a panel cooker. It includes several flat walls or panels that directly reflect the sun’s light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya ,for example ,panel cookers are being manufactured for just two dollars.

The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven .Food cooks quickly in parabolic ovens .However, these cookers are hard to make. They must be re-aimed often to follow the sun .Parabolic cookers can also cause burns and eye injuries if they are not used correctly.

You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

1.If you have much food to cook , you’d better choose________ .

A. a box cooker B. a panel cooker

C. a parabolic cooker D. a paper cooker

2.According to the passage we can conclude that ______.

A. panel cooker is easy to make

B. box cooker is easy to make

C. box cooker is the most effective oven

D. panel cooker is the cheapest oven of the three

3.What is the main purpose of the author in writing the passage?

A. To advertise the solar ovens.

B. To help readers to save cost on fuel.

C. To tell the readers how to make solar ovens.

D. To give the readers brief introduction of solar ovens.

Money matters, no matter who or where you are. So when China’s currency the yuan was devalued (貶值) against the US dollar for three straight days in mid-August, the world felt the effects. As CNN put it: “If China sneezes, the world catches a cold.”

Why does it matter so much?

The exchange rate is the term for the comparison of two currencies. It says how much one currency is worth in terms of (換算) the other.

“Exchange rates play an important role in a country’s level of trade. It is one of the most important determinants (決定因素) of a country’s relative level of economic health,” wrote Jason Van Bergen of Forbes.com. A higher currency makes a country’s exports more expensive and imports cheaper, and vice versa (反之亦然).

Devaluation means the same amount of RMB can be exchanged for fewer USD. For example, on Aug 11, the exchange rate of RMB to USD was 6.23, which meant $1 was worth the same as 6.23 yuan. Two days later, the rate changed to 6.4, meaning the value of RMB had dropped by 2.7 percent.

So what does a weaker currency mean for our lives?

It first affects those who want to travel to, or study in, the US. If your former classmate is leaving for a preparatory (預(yù)科) school in the US at the end of August, it now costs about 1,800 yuan more to exchange currency for 10,000 US dollars than it did earlier this month. However, since many currencies have decreased in value, the value of yuan is still relatively high despite the recent devaluation. This means it costs 1,200 yuan less to get 10,000 Canadian dollars now than it did in March.

Even if we don’t have plans to travel abroad, though, we could still be affected. For example, your mother will have to pay more if she buys directly from overseas websites with US dollars. And chances are that imported chocolate and potato chips will soon be a bit more expensive in your local supermarket.

However, the weaker yuan is good news for Chinese exporters. It makes Chinese exports less expensive and it could boost the overseas sales that have been among the main reasons for China’s economic growth during its rise over the past 30 years.

Just as Erik Britton of Fathom, a London-based economic consulting firm, told The Guardian: “We’re all going to feel it: we’ll feel it through commodities (商品), not just from China but from everywhere that has to compete with it; and we’ll feel it through wages.”

“The devalued yuan will force China’s Asian rivals (競爭對手), such as Indonesia and South Korea, to compete even harder,” wrote Heather Stewart, economics editor of The Guardian. “The result may be cheaper Christmas presents.”

1.According to the passage, it can be learned from the passage EXCEPT___________

A. The higher China’s currency is , the less expensive potato chips from America become.

B. In March people spent 1,200 yuan more to get 10,000 Canadian dollars than they do today because Canadian dollars increased in value.

C. China’s currency’s devaluation against the US dollar in mid-August makes students studying in America pay more school fees.

D. People who work in Fathom will be greatly affected on account of the weaker yuan.

2.The passage implies that ___________.

A. The yuan’s devaluation contributes a lot to China’s economic growth .

B.Exchange rates are the most important factor determining a country’s relative level of economic health

C. The yuan’s devaluation has a great impact on all the countries in the world.

D.Chinese exports sell well overseas because of their high quality

3.If the exchange rate of RMB to USD increased from 6.5 to 6.7, how much more percent would you pay when you bought a bag worth $100?

A. 2.7 B. 5.4 C.20.0 D. 3.1

See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting “print” on your computer.
You might find it hard to believe that you could actually “print” an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3D printer uses are mainly plastic, resin(樹脂) and certain metals. The thinner each layer is—from a millimetre to less than the width of a hair—the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3D printing industry—printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost ￡20，000, while now they cost only about ￡1，000, according to the BBC.
Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of—flutes , bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3D printing becomes more common, it may bring about certain problems—such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3D printer, who will visit a retail store again？” an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun?

1.According to the article, in the future, the 3D printing technology will _______.
A. enable people to make better purchases online

B. change the way we make many products
C. be applied as widely in our daily life as computers
D. shorten the time it takes for people to get what they buy online

2.What happened in the 3D printing industry last year?
A. The 3D printing technology was taken out of the factory.
B. The 3D printing technology began to be used in various fields.
C. The 3D printer was used for medical treatment for the first time.
D. The 3D printer became more affordable for consumers.

3.What is the best title of the passage?
A. Great Demand for 3D Printers B. Technology in the Future
C. Online Shopping Disappearing D. Printing out Everything

4.How is the last paragraph developed?
A. By giving examples.

B. By making comparisons.
C. By analyzing the cause and effect.

D. By presenting research findings.

Peter, a high school student, was pretty busy with school, and he was on the soccer team. High school was hard, because everyone wanted to have nice clothes, hang out, drive cars, and all these cost money. Peter’s father was the sort of guy that believed you had to earn whatever you got, so he wasn’t just about to hand over lots of money for Peter to use to have fun. So, he had to get a job.

During his freshman year summer vacation, his classmate got him a job working on a hay (干草) farm. He threw hay up into wagons as the tractor drove around fields, and then they stacked (剁起) it in the hot barn.（干草棚） It was a hot, low paying job.

He once worked a few nights a week at a grocery store. He put things on the shelf. It was a lot of lifting and carrying, and his arms were strong from this and the previous job. It was dull and didn’t pay much.

He took some time off when soccer got serious, but the following summer he tried working at a lumber（廢舊家具）yard. It was hot outside, but he got a lot of exercise lifting and carrying things like boards and drywall. He also learned a lot about building supplies. It still didn’t pay well.

From there, he spent a year doing some tutoring for a friend of the family, but that was piecemeal. His first real job came the last year at school, when he fixed registers and worked on computers at a big box store. It was his favorite job yet, but it still didn’t pay well.

What Peter realized with all of these jobs was that he needed a better paying job! The only way to get that was to get trained or educated. He could go to school and get a 2?year degree in an office or technical position. His other choices were going to a 4?year college or joining the army. He wasn’t sure what he was going to do yet, but he knew he had to do something. Jobs were a lot of work, money was hard to earn, but he liked staying busy and being able to buy things. Peter wanted the most out of life, and that meant education.

1.How many jobs had Peter taken?

A. Three B. Four C. Five D. Six

2.All the jobs Peter had taken had one thing in common:________.

A. They were done during his vacation

B. They were dull and tiresome

C. They needed hard labour

D. They didn’t pay well

3.________was the most important for Peter if he wanted a good job.

A. Confidence B. Education C. Opportunity D. Wisdom

4.We can learn from the text that________.

A. Peter knew what to do for his future

B. Peter’s father didn’t care about him

C. it was very hard for Peter to make his choices

D. Peter was determined to do whatever he liked

Last week we held a heating discussion on which we should do for our school before we graduate. The students in our class have different suggestion. Some students thought that we can collect money to buy some books for the school library or everything else for the schoo1. Others students think that it’s not necessary to spend money. We can study hard and make our school satisfied with us.

In my opinion, we don’t have to spend money. We can do something meaningfully without money. For an example, we can do some voluntary work to beautify the school and try to get better results in the coming exams so that our school will proud of us.

Modern festival-goers who worry about ending up with a dead mobile phone battery(電池) after days stuck in a muddy field with no electric plug power points may now have a solution——power boots(靴子).

Mobile phone company European Telco Orange has introduced a phone charging(充電) prototype—— a set of thermoelectric gumboots or Wellington boots with a “power generation sole” that changes heat from the wearer’s feet into electrical power to charge battery-powered hand-helds.

The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. “In the sole of the Wellington boot there’s a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge,” Pain said. “That electrical charge we then pass through to a battery which you’ll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone.” These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers. When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made.

But the prototype boot does have one drawback. You have to walk for 12 hours in the boots to make one hour’s worth of charge.

1.The passage is probably taken from _____________ of a website.

A. the business book B. the sports book

C. the science book D. the health book

2.What’s the main idea of the third paragraph?

A. How the boot works to make electricity.

B. How long the boot can be used.

C. Who invented the power boot.

D. The weakness of the boot.

3.Which of the following can replace the underlined word “drawback” in the last paragraph?

A. Benefit. B. Disadvantage.

C. Patience. D. Function.

4.The invention seems to be good news to those___________.

A. who like traveling in the wild

B. who work at home

C. who study at school

D. who work at an office
