Last weekend,my kids along with a few other kids from the neighborhood volunteered to help me wash my car. My 10-year-old daughter came up with the idea of 1    other people's cars as well. It was pretty 2   outside and I had no plans to 3   staying in the bright sun. She 4    wanted to give lemonade (柠檬汽水) to passers-by for free. I had seen little kids 5   and sell fresh lemonade for a small cost but not free. Although I felt 6   ,I decided to help her.

7   she asked me, "What if we 8   this a smile car wash? " I couldn't hold back my tears and 9    her and the other kids to go outside the house and come up with 10    ideas. While I kept myself busy drying the car,the gang walked up to me with a(n) 11    with beautiful images of smiles. They had "Free Car Wash" written on it and the 12    of their exercise was "smile". It was pretty moving to see a team of kids ranging 5-11 years with the 13    to do something for others.

All that seemed 14    and came right from their heart. Nothing seemed to 15    to them: their playtime, the heat outside―they just wanted to 16    others and do something nice in the community!

I helped them make some fresh lemonade and brought out some additional 17   to help clean cars. Passers-by were 18   and one even shouted back to them saying "God Bless You,my kids..." One of them even tried giving them 5 dollars,which they refused. A pretty heartwarming 19    

I feel blessed by being 20   by such wonderful and loving souls.

Forget chip fat,sugar cane or rapeseed oil―the latest source of biofuel could be watermelons.

Scientists have discovered that the fruit is a great source of sugar that can be readily distilled (蒸馏) into alcohol to power cars and farm machinery.

And because sellers reject 360,000 tons of "substandard" fruit annually in America alone, they could be used as an economical way to make fuel.

The waste from US growers could produce nearly two million gallons( nine million litres) of biofuel per year.

In the study,researchers at the United States Department of Agriculture set out to determine

the biofuel potential of juice from rejected watermelons―those not sold due to cosmetic imperfec?tions ,and currently ploughed back into the field.

About a fifth of each annual watermelon crop is left in the field because of surface blemishes (瑕疯) or because they are misshapen.

Dr. Wayne Fish,who led the team,found that 50 percent of the fruit was fermentable (可发酵的) into alcohol which could provide valuable fuel.

"We've shown that the juice of these melons is a source of readily fermentable sugars, representing an unexploited raw material for alcohol biofuel production," he said.

The study, published in the journal Biotechnology for Biofuels,discovered that watermelons could produce around 20 gallons of ftiel per acre from fruit that otherwise would go to waste.

Production of biofuels has been targeted by Western governments as a way to support renewable energy targets.

The European Union has a target for 2010 that 5.75 percent of transport fuels should come from biological sources, but the target is unlikely to be met.

The British government's Renewable Transport Fuel Obligation requires five percent of the fuel sold at the pump by 2010 to be biofueled.

(   ) 1. The passage mainly tells us that        .

     A.  Western countries aim at producing biofuels

    B.  watermelons could be used to make fuel

    C.  the advantage of fuel made from watermelons

    D.  watermelon juice will be the largest source of renewable energy

(   ) 2. Which of the following is NOT the reason why so many watermelons are deserted in America each year?

A. They are substandard. B. They are imperfect.

C. They are misshapen. D. They are oversupplied.

(   ) 3. The underlined word "cosmetic" in Paragraph 5 probably means "      ".

A. inside    B. flavor C. surface    D. freshness
