2）What
some
scientists
have
found

the
land

people's
health.
3）Whoever
wants
to
stay

a
hotel

great
Chinese
poet，was

主语时常用于以下句型：
①It＋be＋形容词(obvious，natural，surprising，etc.)＋that从句
②It＋be＋名词词组(no
wonder，an
honor，a
pity，etc.)＋that从句
③It＋
be＋过去分词(said，reported，thought，etc.)＋that从句
在“It

在“It
+
系动词
+
过去分词

done
was
a
good
question.

be
done
was
a
