以上四个条件句代表四种不同意义的类型。这四种类型的区别完全在于主句和分句中动词形式的相互搭配，因此在讲条件句时，首先要注意动词形式问题。
Type I 是真实条件句
(real condianal)
的一种
在这种条件句中，
if
的意义接近千
whenever,
所以这种句型又叫
"whenever-
型＇，可用于三种场合：
1) 表示普遍真理和客观事实
例如：
If
you
heat
ice,
it
melts.
If
you
pour
oil
on water, it floats.
If
the temperature
drops
to
O
degrees centigrade,
water
由上述诸例可以看出，凡表示不受时间限制的自然法则的条件句，其
if-
分句和主句的谓语动词都用一般现在时：
(If)
simple
present + (Main)
simple pesent
2)

the
movies,
what
kind
of
movie

you
prefer
to

在上述表示现在习惯动作的条件句

分句和主句的谓语动词也都是用一般现在时。
