I found _____ convenient to shop online at home .

it’s 

that

it

that was

考查強(qiáng)調(diào)句。句意：我發(fā)現(xiàn)在家網(wǎng)購很方便。這里it指代后面的to shop online。其中的強(qiáng)調(diào)句式是：主語+find it +形容詞+to do，意為主語發(fā)現(xiàn)做某事是...的，故選C。

--What is happening in that new area?

---New houses          over there.

are built

are building

have built

are being built

考查時態(tài)和語態(tài)。句意：在那個新區(qū)域里發(fā)生什么事情了？那兒建起來許多新的大樓。根據(jù)第一句時態(tài)is happening 可知，時態(tài)用現(xiàn)在進(jìn)行時，故第二句也要用現(xiàn)在進(jìn)行時，主語 houses與build 建立之間是被動關(guān)系，故用現(xiàn)在進(jìn)行時的被動語態(tài)（am/is/are being done），此處為are being built，故選D項(xiàng)。

Don’t mention that at the beginning of the story, or it may             the  shocking end.

give out

give away

give up

give off

考查動詞短語辨析。句意：不要在故事的開頭提到它，否則會泄露令人震驚的結(jié)局。A. give out分發(fā)；B. give away泄露；C.give up 放棄；D. give off發(fā)出（光），根據(jù)“the shocking end”可知，此處表示“泄露”。故選B項(xiàng)。
