Last weekend, I helped my grandparents with their trip to the Dalian. On Saturday morning, together with my grandparents, I search the Internet for the train schedule, the weather in Dalian, and some hotel informations. In the afternoon, they went to the train station and managed to buy two tickets for my grandparents although there had a long queue. After dinner, I packed the things into the suitcase, what my grandparents would need, such as clothes, glasses, an umbrella, a map. The next morning, I went to the station to show them off. Waved goodbye to them on the platform, I felt happily for them and wished them a safe journey.

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£¨°²Åࣩ current to store this electricity, and a lamp whose bulb is a light-emitting diode£¨¶þ¼«¹Ü£©. 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¡ªfor as little as a dollar¡ªon 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¡ªwhich Eight19 expects would take the average family around 18 months¡ªthe 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 afford ably.
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¡ªenough to fuel a couple of smoky lamps¡ªplus $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.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.
3.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
4.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.

Researchers Jose Cordova and Erich Astudillo have discovered a new molecule(·Ö×Ó) that kills the bacteria Streptococcus Mutans, long known to be responsible for breaking down sugars in food in the mouth, which damages tooth leading to decay(¸¯ÀÃ). The new molecule they call ¡°Keep 32¡± has been found to kill the bacteria.
The two have applied for a patent(רÀû) on their discovery and have also begun a marketing strategy aimed at both oral care products and food products. They say either product, if left in the mouth for just 60 seconds ,will kill all the harmful bacteria in the mouth and keep them at bay for several hours. If the new molecule passes health and safety tests, the two believe products using their new molecule should be on the market in as little as a year and a half. They expect the market for such a product to reach $300 million in just the first year.
The two have been working together since 2005 using money from the Founder Institute and say the aim is to approve the process for creating the molecule they¡¯ve discovered for big companies like Procter & Gamble, Colgate even candy companies such as Hershey¡¯s. In interviews, Astudillo has suggested that the two researchers are already heavily into discussion with several companies, some of which are interested in buying the patent once it is approved.
Over the years many products have come on the scene with announcement of reducing tooth decay and even the loss of teeth, but other than the introduction of fluoride(·ú»¯Îï) into drinking water, not much progress has been made. If the announcement made by this new team proves true however, it could foresee a mark in saving the world of tooth decay as well as helping to improve the health for millions of people as tooth decay has been linked to many other health problems throughout the body including heart attacks.
1.The underlined word ¡°them¡± in Para. 2 refers to _________.
A. oral care products B. food products
C. new molecules D. the harmful bacteria
2.The phrase ¡°come on the scene¡± in Para. 4 is closest in meaning to __________.
A. performed B. occurred
C. existed D. arrived
3.What has been a way to reduce tooth decay and even the loss of teeth over the years?
A. Using the molecule ¡°Keep 32¡±.
B. Killing the bacteria Mutans.
C. Introducing fluoride into drinking water.
D. Cooperating with some big companies.

A. many health problems are closely connected to tooth decay
B. the discovery of a new molecule will greatly benefit health care

Food we need
Have you learned a lot about the kinds of food people need? They say that there are several kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds. (2) citrus(¸Ì½Û) fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereal(¹ÈÀà), rice is also in this kind of food; (7) butter, or something like butter.
What food counts
People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn¡¯t matter whether foods are eaten raw(ÉúµÄ) or cooked, canned or frozen. It doesn¡¯t matter if a person eats dinner at 4 o¡¯clock in the afternoon or at eleven o¡¯clock at night. The important thing is what you eat every day.
How shall we do?
There are two problems, then, in feeding the large number of people on earth. The first is to find some ways to feed the world¡¯s population so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.
