有没有need sth. done 或者 sth. need done

Question

有没有need sth. done 或者 sth. need done 还有 老师说need当情态动词时只能用于否定和疑问句 当实义动词时肯否疑都可用 对么？ 具体解说一下。

Answer 1

没有。
need:
1.sb
need
to
do
例：
He
needs
to
do
homework.
2.sth
need
to
be
done
The
bike
needs
to
be
repaired.
3.sth
need
doing=sth
need
to
be
done(和第二点可以相互转换的）
如上面那句也可以表示成：
The
bike
needs
repairing.
need
当情态动词是只能用于否定句和疑问句：
needn't
do
sth
he
needn't
do
his
homework
Need
he
do
his
homework?=Does
he
need
to
do
his
homework?
(如果用作肯定句，那么就和作实义动词时冲突）
作实义动词就是上面的第一点need
to
do
sth
