49. All new employees ______ to attend several training programs.
(A) need
(B) are needed
(C) are needing
(D) have need

以下取自網路:

need用法如下：
1、當動詞：
S + need + N ex. I need you.
S + need + N + to-V ex. I need you to do it.
S + need + to-V ex. I need to do it.
S + need + V-ing ex. The car needs washing. 表被動

2、當助動詞 [用於否定句和疑問句]
S + need not + Vr ex. You need not do it.
Need + S + Vr ...? ex. Need you do it?

以上是need 最常用的部分

這邊回覆6F 

沒有B這樣的用法

也就是be needed to V........不存在

如果這句要用被動要用require這個單字

All employees are required to attend several training programs.

另外 S+need Ving 的用法並不適用於人

所以7F的改法也是不存在

同時給一個用在物的例句

My car needs to be repaired.=My car needs repairing.
