Have you ever wanted to grow your own food in...

Have you ever wanted to grow your own food inside your home? Scientists in Finland have developed a device(设备) that may do just that.

Unlike a usual vegetable garden, it doesn’t need soil. But, the small device, called the Cell Pod, grows plant cells which are safe to eat in the home.

Lauri Reuter, a biologist, says that instead of using the complete plant as food, scientists take only a small part of it–cells–and grow them in a bio-reactor(生物反应器). These plants have much of the same nutritional(营养的) value that a real plant has. The plant cells which are safe to eat, once fully grown, do not look very good. The Finnish researchers say they also need to improve the taste. However, the Cell Pod can provide important things that help your body to be healthy.

Lauri Reuter adds that the new technology will not be instead of fields for growing fruits and vegetables. However, the device could help save natural resources. All you would need to do is add the seed culture(培养物) to the device, give it water, sit back and then wait. The machine does the rest of the work.

The researchers hope to have a form of the Cell Pod on the market in the next ten years.

1.If you want to grow vegetables inside your home, you need __________.

A. real plants and water　　 B. the seed culture and the Cell Pod

C. the cells and the soil　　 D. the complete plant and the device

2.What can we learn from the passage?

A. The plant cells are more delicious than the real plants.

B. People will not grow fruit and vegetables in the fields.

C. The plant cells are not only healthy but good-looking.

D. People may buy the Cell Pod on the market in the future.

3.What does the writer think of the Cell Pod?

A. It is a usual vegetable garden at home.

B. It is a new useful device for growing food.

C. It is a difficult way of growing plants.

D. It can provide all the nutrition for our body.

Do you ever throw away food at home? Have you ever thought about what happens to the food that shops and supermarkets don’t sell? Well, you might be shocked (震惊) to find out that nearly one third of food produced for human gets lost or wasted. What’s more, around 800 million people in the world do not have enough food to lead a healthy life.

Many people in the UK and across the world are trying to do something about this imbalance and make use of thrown-out food that can be perfectly eaten. For example, there is a cafe in Leeds (UK) whose meals are all created using unsold food from supermarkets, including a lot of vegetables, fruit, fish and other things. This unwanted food is turned into delicious soups and all kinds of dishes that feed the hungry people of Leeds. Customers simply pay what they can afford, or help with the washing up. In just ten months, 10,000 people were fed at this cafe, using twenty tons of unwanted food!

Also, last year the UK’s first food waste supermarket opened. The supermarket is near Leeds and works on a “pay as you feel”; customers pay whatever they want for the produce. The stock (库存) changes daily but you can usually find things such as fresh vegetables, fruit and milk there. Some low-income families have said that it has changed their lives.

“Fuel for School” is another food waste project. Surplus (多余的) food from supermarkets such as vegetables, fruit and bread is used to feed hungry schoolchildren whose families may not be able to afford to buy them lunch.

I lived in Leeds for three years, and have had lunch at a food waste cafe, and it was delicious. I couldn’t believe that it was all food that supermarkets had thrown away! I have also taken part in projects such as “Foodcycle”, using supermarkets’ unwanted food to cook meals for poor people.　　

More cafes like this are being opened in other parts of the UK, and it is now becoming popular in the world. I think this is an amazing act as food waste is one of the world’s biggest problems. I also believe that the law should be changed, so that supermarkets don’t throw away so much perfectly good food!

1.800 million people in the world can’t live a healthy life because of ______.

A. unsold food　　 B. unwanted food

C. being unable to work　　 D. being short of food

2.According to the passage, the writer agrees that ______.

A. buying the waste food can protect the environment

B. all the people in the world make use of waste food

C. food waste in the world can be solved by the UK soon

D. the government should make the law to stop food waste

3.What is the writer’s main purpose in writing this passage?

A. To encourage people to save food.

B. To introduce some supermarkets in the UK.

C. To share his personal experience in saving food.

D. To explain why he cooked meals for poor people.

Do you have to wear uniforms to school every day? Do you like them or you just want to wear your own clothes? Many students just wonder why they can't wear whatever they like, for teenagers want to be different from others.

In fact, there are several reasons why school uniforms are a good idea. First of all, uniforms help the school look smart. The students feel that they belong to a particular (特别的)group. When every student in the school wears the uniform, nobody has to worry about fashion. Everybody wears the same style of clothes. Uniforms can be useful in unexpected ways. A school in Ireland has introduced an interesting new uniform. On the edge (边缘)of the jacket, there is a piece of cloth which gives off light in the dark. When the children are walking or cycling to school on dark mornings, car drivers can easily see them.

But can uniforms help improve school standards? The answer to this question is not clear. One study in America found that students5 grades improved a little after the school introduced uniforms. But some students didn't want to wear the uniform. Other American studies showed that uniforms have nothing to do with the school performance.

School uniforms are traditional in Britain, but some schools are starting to get rid of them. Students of some very good schools do not have to wear uniforms now. However, uniforms are still popular. Pupils at about 90 percent of British secondary schools wear uniforms.

1.Where are the interesting and useful uniforms from according to the passage?

A.Ireland. B.America. C.China. D.Britain.

2.Why can the new uniform be useful?

A.The whole jacket can give off light in the dark.

B.Students can wear it on dark mornings.

C.Students can wear it to walk or ride bikes.

D.It can make drivers see the students easily in the dark.

3.What’s the meaning of the underlined phrases in the last paragraph?

A.喜欢 B.使用 C.摆脱 D.改变

4.How does the writer start this passage?

A.By asking questions. B.By listing facts.

C.By showing numbers. D.By giving examples.

Your second job is to price your product. You want your product to be in high demand (需求). People should want your product. But they should also be able to buy it. Check store prices on products that are like yours.

Collecting Information

Work out the production costs by adding the material costs and the labor costs. (material)_______+ (labor)_______ = (production costs)_______

.Now you know what it will cost to make this item. How much do you want to charge for the item? Think about how much profit you want to make. Look back at the notes of your survey. How much will students spend for your product? Put together what you find out. What will you charge? (production costs) _______+ (profit) _______= (product price) _______

Now it’s time to show what you know. Good luck!

Every day we use money to buy what we want. But have you ever really noticed the bill (钞票) in your hand? There are different pictures on both sides of banknotes (纸币) and interesting stories behind them.

Most banknotes have famous people on the front, such as a country’s leader or a great scientist, while on the back of the paper note there are usually some well-known scenes or national buildings.

The latest editions of Chinese banknotes use the picture of Mao Zedong, founding father of the People’s Republic of China, on the front of all yuan bills. However, the backs of the bills are different. The Great Hall of the People, on the 100-yuan note, is a landmark (地标) in Beijing. Important meetings are always held there. The Lijiang River in Guilin, on the 20-yuan note, is one of the most beautiful scenes in the world.

The US 1-dollar bill has the first president, George Washington, on the front side. A 13-level pyramid is on the back. Benjamin Franklin, a great scientist and politician (政治家) from the US, appears on the front of the 100-dollar bill. You can see the White House, where the presidents live, on the back of the 20-dollar bill.

1. According to Paragraph 2, which one probably appears on the back of the banknotes?

A. Abraham Lincoln.            B. Elizabeth II.
