Right in the middle of the town are some long ponds(水池). They are only about half a foot deep. The men of Symi dug out the earth to make the ponds.
Over each pond is a low cover. It is made of glass that you can see through.
At night, sea water is taken into the ponds. The next day, the hot sun shines through the covers. The sun light turns the water into vapor(水蒸氣) and the vapor goes up from the ponds. The salt is left behind.
As it goes, the vapor became mist. On the inside of each cover, the little drops of mist run together to make big drops. These drops run down the sides of the cover, filling other ponds with fresh water.
The salt left in the ponds is washed out each night. Then more sea water is taken in. The factory is ready for the next day’s work. The covers and other parts of the factory cost very little. Sea water and sun cost nothing. Most people of Symi are poor. So to them this new way of getting fresh water seems wonderful.
【小題1】 Where are the little drops made into big drops?

A．On the inside of the covers.
B．In the ponds with fresh water.
C．On the walls of the salt water ponds.
D．Between the fresh water and the salt water.
【小題2】The men of Symi dug some long ponds        .
A．in order to keep sea water
B．in order to get hot water inside
C．in order to fill them with fresh
D．in order to get fresh water
【小題3】Which picture shows the right way to get fresh water in Symi?

【小題4】Which of the following is NOT true?
A．The sea water is taken into the ponds at night every day.
B．There is a very big river running through the town to the sea.
C．The people in Symi can get fresh water from the factory.
D．People may see the water in the ponds through the cover.


【小題1】A
【小題1】D
【小題1】C
【小題1】B

解析【小題1】根據(jù)第二行的第一段On the inside of each cover可知，水蒸氣在玻璃內(nèi)側(cè)形成大的水滴。故選A。
【小題1】根據(jù)最后一段的最后一行可知，這是一種新的、經(jīng)濟(jì)的獲取淡水的方法。人們挖水池是為了獲取淡水。故選D。
【小題1】水蒸氣變成水滴后會下落，A、B、D三幅圖中，水滴會重新落入海水中，不能獲得淡水。而C項(xiàng)所示的是，水滴流到外側(cè)，再流進(jìn)其它的池子里。故選C。
【小題1】根據(jù)第一段的第四行可知，A項(xiàng)正確；根據(jù)最后一段可知，C項(xiàng)正確；根據(jù)第一段的第三行“...you can see through”可知，水池上面用玻璃覆蓋，人們可以看到水池里面，D項(xiàng)正確。故選B。

As soon as you land at London Heathrow airport, you will see it is easy for you to ride the subway or take a bus to your hotel. However, if you are planning on touring London, it would be the best idea for you to rent a car so that you can go wherever you wish to visit freely and you don’t have to run to catch a bus or a train. Remember that the trains in London are always very crowded. So a rental car is the easiest and most comfortable way to travel.
London has so many different attractions（旅游景點(diǎn)） to offer and the same is true for England itself. In London you can find Buckingham Palace, which you can also visit during summer time when the Queen of England goes to one of the castles（城堡）around the country. If you are interested in history and art, you can’t miss the National Gallery, which is right in front of Trafalgar Square. Not far from Trafalgar Square, there is the House of Parliament that faces the Thames River. If you wish to have a good view of London, then the best idea would be to take a ride on the London Eye, the tallest Ferris wheel（摩天輪）of Europe. The tour takes about half an hour so you can sit comfortably and take pictures of London from above.
London is not too far from other major cities and attractions in England. For example, a drive of only one hour and a half will take you to Cambridge and with even less time than that you can reach Stonehenge to see the stones that have been there for centuries.
【小題1】According to the passage, the best way for you to tour London is ______________.

A．to take the subwayB．to take buses
C．to take the trainD．to rent a car
【小題2】If you wish to take pictures of London from above, you’d better ______________.
A．pay a visit to the National Gallery
B．visit Buckingham Palace
C．take a ride on the London Eye
D．take a plane
【小題3】Among these attractions, _____________ are in London.
①Buckingham Palace
②The London Eye
③Stonehenge
④Trafalgar Square
A．①②③B．②③④C．①②④D．①③④
【小題4】Which of the following is NOT true?
A．By visiting the National Gallery, you can learn much about history and art.
B．The House of Parliament lies by the Thames River.
C．Cambridge is just one and a half hours’ drive from London.
D．The stones in Stonehenge have been there for only a hundred years.

For years I wanted a garden. I’d spend hours thinking of different things I could plant that would look nice together.
But then we had Matthew, and Marvin, and the twins Alisa and Alan, and then Helen. I was too busy raising them to grow a garden.
Money was not enough. Neither was time. Often when my children were little,one of them would want something that cost too much, and I’d have to say, “Do you see a money tree outside? Money doesn't grow on trees, you know.”
Finally, all the children got through high school and college and were off on their own. I started thinking again about a garden.
Then, one spring morning, on Mother’s Day, I was working in my kitchen. Suddenly, I looked out of the window and there was a new tree, planted right in my yard. There were things blowing around on it. Then I put my glasses on—and I couldn’t believe what I saw.
There was a money tree in my yard!
I went outside to look. It was true! There were dollar bills*, one hundred of them, hanging all over that tree. There was also a note among them, “Thank you for your time, Mom. We love you!”
Later, my children bought me tools, ornaments, a sunflower stepping stone and gardening books. A new page started in my life.
That was three years ago. My garden’s now very pretty, just like I wanted. When I go out and take care of my flowers, I don’t seem to miss my children as much as I once did. It feels like they’re right there with me. Now every year when winter comes, I look out of my window and think of the flowers I’ll see next spring in my little garden. I think about what my children did for me, and I get tears in my eyes—every time.
I’m still not sure that money grows on trees. But I know love does!
