知识精讲
1.Why

harmful(形容词)有害的；导致损害的
由harm+形容词后缀ful
构成
反义词：harmless无害的
be
harmful
to=be
bad
for对...有害
e.g.
Watching
TV
too
much
is
harmful
to
your
eyes.
看电视太多对你眼睛有害。

harm---harmful
词性转换
harm:(1)动词，
伤害，损害

（2）名词，

2.Smoking

plant
millions
of
trees
every
year.
每年我们种植数百万颗树。
（2）million
前面有基数词表示确切数目时，million后不加s。
