throwing

being thrown

to throw

to be thrown

考查非謂語動詞。句意：陽光熾白炫目，在地上投下濃重的陰影。主語The sunlight和throw是主動關系，因此要用現(xiàn)在分詞表主動，此處是現(xiàn)在分詞短語作狀語。故選A項。

need

can

would

考查情態(tài)動詞辨析。句意：你不需要知道作者的名字就能找到一本書。你可以按書名找到這本書。A.must必須，一定；B.need 需要；C. can可能；可能；D.would愿意。根據(jù)句意可知，此處表示一種客觀的可能性，應使用情態(tài)動詞can。故選C項。

考查虛擬語氣。句意：我多么希望每個家庭都有一個帶著美麗花園的大房子！此句是wish 引導的從句，從句要用虛擬語氣，根據(jù)wish 可知是與現(xiàn)在事實相反，從句一般用過去時。故選c項。

          no bus,we had to walk home.

There was

There being

Because there being

It being

考查獨立主格結構。句意：沒有車，我不得不走路回家。根據(jù)句意，表示“存在”，要用there be 句型；分析句子可知，設空處應用非謂語動詞，there be只有主動形式，故用現(xiàn)在分詞；因為非謂語動詞有自己獨立的的主語no bus,所以此處是獨立主格結構。故選B項。

that

until

before

since

考查固定句型。句意：在線課程已經(jīng)開始六個月了。A. that 那，那個；B. until直到..... 為止；C. before在.....之前；D. since自.....以來。分析句子可知，句中涉及固定句型“ It is +一段時間+since引導的時間狀語從句”，意為“自從......以來已經(jīng)有多長時間了”，since從句中用非延續(xù)性動詞。故選D項。

amazing

amazement

考查形容詞辨析。句意：知道長頸鹿的長脖子上只有7塊骨頭，真是令人驚訝。分析句子結構可知，is是系動詞，空格處需填形容詞作表語。主語是It,指物，表示“令人驚訝的”，應填amazing。故選C項。

--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)在進行時，故第二句也要用現(xiàn)在進行時，主語 houses與build 建立之間是被動關系，故用現(xiàn)在進行時的被動語態(tài)（am/is/are being done），此處為are being built，故選D項。
