“I’ve changed my mind. I wanted to have a telescope , but now I want my dady back .” Lucien Lawrence’s letter to Father Christmas written after his schoolteacher father had been knifed to death outside his school gate , must have touched every heart .Lucien went on to say that without his father he couldn’t see the stars in the sky . When those whom we love depart from us , we cannot see the stars for a while .
But Lucien , the stars are still there , and one day , when you are older and your tears have gone , you will see them again. And , in a strange way , I expect that you will find your father is there too , in your mind and in your heart . I find that my parents , long dead now , still figure in many of my dreams and that I think of them perhaps more than I ever did when they were alive . I still live to please them and I’m still surprised by their reactions . I remember that when I became a professor , I was so proud , or rather so pleased with myself , that I couldn’t wait to cable my parents . The reply was a long time in coming , but when it did , all Mother said was “I hope this means that now you will have more time for the children !” I haven’t forgotten . The values of my parents still live on .
It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care . Would I have been as ready as Philip Lawrence have been to face the aggressors (挑衅者), and to lay down my life for those in my care ? How many people would want me back for Christmas ? It’s a serious thought , one to give me pause .
I pray silently, sometimes , in the dead of night , that ancient cry of a poet “Deliver my soul from the sword , and my darling from the power of the dog .” Yet I know the death comes to us all , and sometimes comes suddenly . We must therefore plan to live forever , but live as if we will die tomorrow . We live on , I’m sure , in the lives of those we loved , and therefore we ought to have a care for what they will remember and what they will treasure . If more parents knew this in their hearts to be true , there might be fewer knives on our streets today .

内容概要：本文主要讲的是使海水变为淡水的各种方法。
1、选B。通读全文可知，本文主要讲的是使海水变为淡水的各种“方法”。
2、选C。boil和rise两个现象应该是同时发生的。
3、选C。根据常识，水沸腾时，上升的应是“蒸汽”(steam)。另从下一句也可推知。
4、选C。从上一句话可以推知。
5、选B。表示三者以上的另一个用another，另从下节首句中也能得到启示。
6、选A。从第七个空格处所在的句子可以推知，这里利用的是太阳的“热能”。
7、选B。余者不可能使水变热。
8、选D。太阳使水变热后，会有蒸汽“上升”。
9、选C。根据下一句可推知，蒸汽上升后，在“玻璃”上逐渐冷却变成了水，最后水顺着玻璃流入小槽。
10、选D。水应由上“向下”流。
11、选A。根据本节内容可知，这种办法是“凝固”海水。
12、选B。根据下句“然后科学家便清洗掉盐”可推知，附着在冰面上的应是“盐”。
13、选A。B、C不合语境，D（take off）“取走”，较为笼统，不及A（wash off）“清洗掉”表意准确。
14、选C。清除掉盐后，剩下的冰便是淡水了。这里fresh的意为“无咸味的，（水）淡的”。
15、选D。work意为“行得通”。余者不合文意。
16、选A。句中没有情态意味，应舍去B、C、D。
17、选B。这句话显然是对上一问题的“回答”。`
18、选A。根据下一句话以及常识可推知，这要花许多“钱”。
19、选C。根据词的用法选定。主语是人时一般不用cost、take，另save不合文意。
20、选B。根据上下文可以推知，科学家们正在“寻找”更好的方法，而不是“关心”、“等待”和“依靠”更好的方法。

Dear Editor,
I’m writing to tell you about our discussion we had on the afternoon of last Wednesday about the good and bad sides of setting off firecrackers during the spring festival. 20 boy and 20 girl students attended the discussion. As a result, 40% of them believe that setting off firecrackers certainly adds pleasure and joy to the festival, therefore, it is a wonderful tradition. But another 40% of the students think that setting off firecrackers causes air and noise pollution, and what’s worse, it sometimes causes terrible accidents to us and to our property. The other 20% have never thought about it or don’t care a bit. In my opinion, ……
