　　Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh.

　　Why aren't there many factories like the Symi factory?

　　In some places, the sun isn't hot enough, or it doesn't shine every day. In these places, other ways of heating seawater can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat, a lot of fresh water can be made quickly.

　　But heating is not the only way to get fresh water from salt water. Other ways are tried. One way is freezing. The fresh part of salt water freeze., first. To get fresh water, the pieces of ice are taken nut.

　　Which way is best? The one that gives the most water for the least money. It may be a different way for each place.

　　Symi's way seems very good for small, hot places. It doesn't make very much water at a time. But the factory is easy to build and cost little.

　　That's why people in many dry places talk about Symi!

Answer 1

答案：B;A;C;B;D
解析：

1．B（通過閱讀整篇短文，尤其是根據(jù)短文第一段所敘述的世界許多地方需要更多的淡水及句子Every country is trying to find ways to turn salt water into fresh．可得到答案B．） 　　2．A（短文第一段敘述了每一個(gè)國(guó)家都在盡力探索把海水變成淡水的方法，在根據(jù)短文第二段中表示反問的否定特殊疑問句Why aren't there many factories like the Symi factory？就不難推斷出Symi factory是一個(gè)淡水加工廠．） 　　3．C（根據(jù)短文倒數(shù)第二段的Symi's way seems very good for small，hot places．可知，Symi的方法是小而炎熱的地方獲取淡水的最好方法．） 　　4．B（短文首段敘述了Many places in the world need more fresh water．Every country is trying to find ways to turn salt water into fresh．以下各段都敘述了從海水里提取淡水的不同方法，如：Symi工廠制造淡水，加熱海水，冷凍海水等．從全文考慮，只有B項(xiàng)才能概括全文．） 　　5．D（短文敘述了從海水中提取淡水的Symi工廠似乎對(duì)小而炎熱的地方比較合適．雖然用這種方法每次不能制造出許多的淡水，但工廠容易建造，花費(fèi)也少．再根據(jù)短文的結(jié)束句That's why people in many dry places talk about Symi！就可以判斷出Symi的方法在干燥的地方不能奏效的說法與事實(shí)不符，所以選D．）
