Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to get round this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp(安培) current to store this electricity, and a lamp whose bulb is a light-emitting diode(二極管). The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again.

The trick is that, to be able to use the electricity, the system's keeper must buy a scratch card—for as little as a dollar—on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit. 

Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards—which Eight19 expects would take the average family around 18 months—the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell. 

In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably.

According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil—enough to fuel a couple of smoky lamps—plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the cost of solar technology falls, it should get even cheaper.

1.The underlined word “get round” in the first paragraph can be replaced by _______ .

A.make use of       B.come up with       C.look into          D.deal with

2.What should the user do when the electricity in the battery is used up?

A.Buy a scratch card.                      B.Recharge it outside.

C.Buy another solar cell.                    D.Return it to the company.

3.How much would users pay for the cell and scratch cards before they own a 2.5-watt solar cell?

A.Around $10.       B.Around $80.       C.Around $90.       D.Around $180.

4.It can be inferred from the last paragraph that  ____________.

A.Kenyan families would find it difficult to afford the solar cell

B.using the solar cell would help Kenyan families save money

C.few Kenyan families use mobile phones for lack of electricity

D.the company will make a great profit from selling solar cells

5.What might be the most suitable title for the passage?

A.Solar Energy: Starting from Scratch.

B.Eight19: a creative British Company.

C.Kenyan Families: Using Solar Energy for Free.

D.Poor Countries: Beginning to Use Solar Energy.

It was graduation day at the university where I work and a beautiful day quite unlike the first graduation I attended as a young professor.On that cold day years ago, as we watched the students walking into the hall, one of my colleagues turned to me and said, "Graduation will be one of the happiest and one of the saddest time of your life." At my inquiry, he answered, "Because the students you have gotten to know have to leave."

As years went by, my previous confusion about my colleague's words no longer existed.When I came across naughty students, I have had to rethink why I chose to be a teacher.It obviously isn't the money.Once a former computer science student of mine called me, asking me if I wanted to have a change.He was working at Nintendo Corporation.His salary was higher than my current one, though I have more education and have worked for over a decade.With my programming skills, he said he could get me hired.I thanked him, but declined his kind offer.

A few days before this current graduation, while working on final grades, I found a note a student had slipped in with her homework.She thanked me for being her teacher and said the things she had learned in my class—not about math, but about life—would be things she would remember long after the math skills had faded away.As I finished reading, I remembered why I had become a teacher.

Now, on this sunny graduation day, as I again observed the sea of blue hats and gowns, I did so with renewed dedication (奉獻(xiàn)) and a deeper sense of satisfaction—I will always be grateful that I am a teacher.

1.Hearing his colleague's description of graduation for the first time, the author __________.

A.quite agreed with his colleague

B.was very puzzled

C.thought it very funny

D.was very sad

2.The computer science student called up the author because he___________.

A.wanted to inform the author of his present job

B.tried to persuade the author to work with him

C.wanted the author to share his joy and satisfaction

D.thought the author wasn't fit to be a teacher

3.The underlined part “blue hats and gowns” refers to___________.

A.university colleagues

B.graduates' clothes

C.life memories

D.decorations in the hall

4.The author wrote this passage to __________.

A.express his devotion to being a teacher

B.compare two different graduation ceremonies

C.talk about the meaning of graduation

D.give advice on how to be a good teacher

Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.

Garlic (大蒜) is one of the most common spices of the kitchen, and the good news is that growing garlic indoors is simple. Garlic can be easily grown at home from individual cloves (瓣), which is the most commonly used form of cultivating garlic than growing garlic from seeds. Here are some useful tips on growing garlic indoors.

Autumn is the best time to plant garlic. Garlic requires enough time to develop strong roots. In warmer climate, it can be delayed to late winter or early spring.

Ensure the container used to grow garlic is large enough for the roots to have enough space to grow. The larger the size of the container, the healthier and bigger the garlic bulbs (鱗莖) will be. The container should also have holes at the bottom so that the water can drain (流走) out easily.

Sow each clove vertically into the soil at a depth of one inch. Ensure that the bluntend (平端) is facing downward. In case of container gardening, the number of cloves to be sowed in each container depends on the size of the container. In case you are planning to sow more than one clove in each container, make sure that each clove is at least 5 inches apart from others.

For the best growth of the garlic plant, choose a sunny spot where there is enough air circulation (流通). This will aid evaporation (蒸發(fā)) of too much amount of water and prevent the soil from becoming too damp in case too much watering does occur. Window sill (窗臺(tái)) is a good place to put your container of garlic plant.

Once the clove has been sowed, cover the soil with a layer of mulch (覆蓋物) to protect the roots from extreme cold. Provide fertilizer at the correct time in right amounts, and proper watering. Once the garlic tips start appearing in the spring season, pull back the layer of mulch. Feed the plants once or twice every month with fertilizer.

李華是一名高一年級(jí)的中學(xué)生,閱讀她的這篇日記,然后按照要求寫(xiě)一篇150詞左右的英語(yǔ)短文。

August 6, 2010                           Sunny

Half of my summer vocation has passed. It's supposed to be the time for me, a senior- one student, to relax, read novels, chat with friends and, anyway, not to worry about getting up at 7 am for class.

Even before the vocation, I had been arranged to attend different "enrichment" classes to improve my main subjects. My mum did ask for my opinion whether I would like to go to such classes. But could I refuse? My negative reply would cause a long persuasion, which I would not face.

Besides, the teachers made summer homework lists as we were sent off for vocation. The reason sounds persuasive -- to keep us studying during the long break so we wouldn't forget our lessons.

I found that the joy of my summer vocation had been stolen. But do I blame my mum or my teachers? Of course not. Though I don't like listening to my mum's lessons about society competition, I still understand that I should do well in study. What bothers me is that I don't feel like sitting in the classroom focusing my mind on the teachers' lectures. My mind is staying outdoors, tasting the freedom of the blue skies, the power of sunshine and the comfort of gentle wind....... not only scores or certificates.

【寫(xiě)作內(nèi)容】

1.以約30個(gè)詞概括短文的要點(diǎn);

2.然后以約120個(gè)詞就“中學(xué)生在暑假參加學(xué)習(xí)班”的現(xiàn)象發(fā)表看法,并包括如下要點(diǎn):

1)你認(rèn)為中學(xué)生在暑假參加強(qiáng)化學(xué)習(xí)班(enrichment classes)是否有好處?

2)以你自己或身邊的實(shí)例說(shuō)明你的觀(guān)點(diǎn);

3)對(duì)中學(xué)生的家長(zhǎng)們提出建議。

【寫(xiě)作要求】

【評(píng)分標(biāo)準(zhǔn)】
