--What is happening in that new area?

---New houses over there.

are built

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。

There's no simple solution this problem.

of

for

to

about

考查介詞。句意：這個問題沒有什么簡單的解決方法。此處是短語“

the solution to....的解決方法”，應(yīng)用介詞to。故選C項。

When to someone,I usually say, "Pleased to meet you."

introduce

introduced

introducing

am introduced

考查過去分詞和省略。句意：當(dāng)我被介紹給別人時，我通常會說：“很高興認(rèn)識你”。根據(jù)句子結(jié)構(gòu)可知，本句是when引導(dǎo)的時間狀語從句，原句when I am introduced to someone,這里當(dāng)從句主語與主句主語一致時，并且從句的謂語動詞有be這時從句的主語與be同時省略，所以空格處introduced。故選B項。

---Her father is very rich.

--- She wouldn't accept his help even if it were offered.

What for?

So what?

No doubt

No wonder

It is well-known that crack cocaine is a powerful drug and users become to it much more easily if they smoke it.

addicted; addict

addictive; addict

addicted; addictive

addictive; addicted

考查形容詞辨析。眾所周知可卡因是一種強大的令人上癮的毒品，如果使用者吸了它更容易上癮得多。addicted上癮的，著迷的；addict"shi使沉迷；使上癮”是動詞；addictive “使成癮的，令人沉迷的”。第一空表示“令人上癮的”用addictive，故排除A，C項；become addicted to “對....上癮”，第二空填addicted。故選D項。
