求求各位大哥大姐了，帮我做几道英语题目吧！！！2008年6月21日就要了！！！

(1) freezes
(2) keeps
(3) lies
(4) believe;are telling
(5) does; work; is trying

(1)(2)都是客观真理，所以用一般现在时
（3）也在陈述事实，故用一般现在时
（4）后面要用进行时，因为有now
（5）的前两个空不太确定，因为并没有明显的时态提示，个人认为一般现在时就可以了。后面用进行时

1、Water_freezes_(freeze)at the temperature 0 degrees.
2、The air keeps (keep)moving all the time.
3、The town lies (lie)to the west of the hill.
4、I believe (believe)you can tell (tell)the turth now.

teacher:Oh,yes,he is trying(try)his best now.
