通常是事物(也可以是人)作want，need, require，deserve等動詞的主語時(shí)，表示事物(或人)客觀上“需要……”，用動名詞一般式的主動形式作賓語表示被動意義。若動名詞是不及物的，后面還應(yīng)有相應(yīng)的介詞。
The children need looking after.孩子們需要照看。
這種用法還可把動名詞改為動詞不定式的被動形式來表被動。
The children need to be looked after.

The rock is hard to break.這塊巖石很難打碎。
不定式符號to在被動語態(tài)中不可省略

【解析】考查時(shí)態(tài)和語態(tài)。由句中的時(shí)間狀語in the past years可知，這里應(yīng)用現(xiàn)在完成時(shí);句子的主語new substances與discover之間為動賓關(guān)系，故選D項(xiàng)。
【答案】 D
22.(2010屆成都聯(lián)考)—Look!Everything here is under construction.
—What’s the pretty small house that________for?
A.is being built B.has been built
C.is built D.is building
【解析】考查時(shí)態(tài)和語態(tài)。語意表明從句中用現(xiàn)在進(jìn)行時(shí)，名詞house是動詞build的承受者，所以謂語用現(xiàn)在進(jìn)行時(shí)的被動語態(tài)。第二句語意為：正在修建的那座漂亮的小房子是用來做什么的?
【答案】 A
23.(2010屆江西高安中學(xué)月考)—Did you have any trouble finding your way in Shanghai?
—Yes，I tried to find my way to the airport but________.
A.has been lost B.get lost
C.lost D.got lost
【解析】前面的問句以及tried暗示時(shí)態(tài)應(yīng)為一般過去時(shí)，因此選got lost。
【答案】 D
24.(2010屆皖南八校聯(lián)考)We’ve been told the good news，but when and where to go for the exciting paid vacation________yet.
A.are not discussed
B.have not been discussed
C.is not being discussed
D.has not been discussed
【解析】后一分句的主語為when and where to go for the exciting paid vacation，表示的是一件事，謂語動詞用單數(shù)形式，由此排除A、B兩項(xiàng)。根據(jù)句末的yet可知應(yīng)該用完成時(shí)，即這件事還沒有被討論。
【答案】 D
25.(2010年西安質(zhì)量檢測)We haven’t moved into the new office building—it________right now.
A.is decorating B.has been decorated
C.is being decorated D.has been decorating
【解析】考查動詞時(shí)態(tài)、語態(tài)。根據(jù)題干中前面一句話的時(shí)態(tài)及后一句話中的時(shí)間狀語right now可知，應(yīng)用現(xiàn)在進(jìn)行時(shí);又依據(jù)語意可知，房子正在(被)裝修，因此選C。
【答案】 C
