was

were

has been

have been

考查時態(tài)和主謂一致。句意：兩年前，工廠將大量廢水排入河中。根據(jù)two years ago 可知，句子使用一般過去時。....amounts of修飾不可數(shù)名詞作主語時，謂語動詞用復數(shù)形式，即謂語動詞與amounts保持數(shù)的一致。故選B項。

I think it           that she should be knowledgeable about Music for her present job.

urgent

normal

essential

gifted

考查形容詞詞義辨析。句意：我認為她對音樂的了解對她目前的工作是必要的。A. urgent緊急的；B. normal普通的；C. essential基本的、必要的；D. gifted有天賦的。根據(jù)句意以及后接賓語從句為

The law           equal rights for men and women.

permits

confirms

persevers

guarantees

考查動詞辨析。句意：這個法律確保了男女權(quán)利平等。A.permit允許；B.confirm證實，證明；C.persever堅持；D.guarantee保證，擔保。分析句意可知，空格處為動詞做謂語，其主語為the law,為單數(shù)則謂語動詞用第三人稱單數(shù)形式。又因the law作用是保證公平。故選D項。

If you don't understand something, you may resrarch, study, and talk to other people          you figure it out.

because

though

until

since

考查連詞。句意：如果遇到不懂的東西，你可以搜索、研究，和別人交流直到弄明白。A. 因為； B. 盡管；C.until直到；D.since自從，因為。根據(jù)句意可知，until符合語境。故選C項。

考查名詞辨析。句意：作為一名學生，如果你養(yǎng)成課后復習的好習慣，那么你的表現(xiàn)就會很優(yōu)異。A.operation 操作； B. growth生長；C. performance 表現(xiàn)；D.character性格。學生如果有課后復習的好習慣，會表現(xiàn)優(yōu)秀。故選C項。

考查情態(tài)動詞。句意：根據(jù)協(xié)議，所有款項應在月底付清。shall用于法律，條款中表示必須要做的事。故選C項。

Wouldn’t it be         wonderful world if we lived in         harmony with nature?

a; /

the; /

a; the

the; the

考查冠詞和短語。句意：如果我們與自然和諧相處，這不是一個美好的世界嗎？第一個空中，world表示泛指，應用不定冠詞且wonderful發(fā)音為以輔音音素開頭的單詞，故應用a;第二空短語in harmony with表示“與....和諧”，中間不加冠詞。故選A項。

— Father, you promised!

—Well,____．But it was you who didn't keep your word first．

so was I 

so did I 

so I was 

so I did

考查部分倒裝“So + be/情態(tài)動詞/助動詞 + 主語”與表強調(diào)的“So + 主語 + be/情態(tài)動詞/助動詞”區(qū)別。根據(jù)語境“you promised（你許諾過）”和答語“But it was …”可知爸爸回答“我的確許諾過”，且promised是過去時，所以表強調(diào)要用助動詞did,故選D。句意：——爸爸，你許諾過?！美?，我的確許諾過。但是是你先沒有遵守諾言。
