—_____ her son passed the driving test.

A．That

B．Because

C．Since

D．When

Answer 1

A

考查從句。句意：什么使她如此高興？她兒子通過(guò)了駕駛考試讓她如此高興。_____ her son passed the driving test補(bǔ)充完整是_____ her son passed the driving test made her so happy。所以_____ her son passed the driving test是主語(yǔ)從句，且從句句意完整，用That引導(dǎo)，B,C不能引導(dǎo)主從，而D只能做狀語(yǔ)。
