Answer 1

【答案】

【1】located

【2】every/each

【3】an

【4】have been using/have used

【5】Besides

【6】who/that

【7】in

【8】polluted

【9】importance

【10】if/because

【解析】

【1】考查固定搭配。be located on.是固定搭配，意為位于。因為cities不是人，不能執(zhí)行動作，所以要用被動語態(tài)。同時還有be located in/at的用法。故填located。

【2】考查every/each的用法。 every/each在這里作形容詞，意為每一個，由” and almost 【2】_______ country has at least one river flowing through it”可知，這里既不能填all，因為與almost不能同時使用，也不能填no/none，因為那不符合實際情況。故填every/each。

【3】考查固定搭配。Play an important part in是一個固定搭配，意為在……扮演一個重要角色。同時也考查冠詞用法。因為important開頭的元音字母發(fā)元音，不能填a，故填an。

【4】考查現(xiàn)在完成進行時/現(xiàn)在完成時的用法。由” Since the beginning of history, people 【4】_______ (use) rivers for transportation.”可知，這里的意思應(yīng)該是很久以前，人們就使用河流來進行運輸。而到現(xiàn)在人們也還是在使用河流，故是從過去某時開始一直持續(xù)到現(xiàn)在的東西，并且還將持續(xù)下去。故填have been using/have used。

【5】考查介詞用法。besides意為除了……之外。前文說了河流的運輸作用，后文說” rivers give water to drink, water for crops, and chances for fun and recreation for the people 【6】______ live along their banks.” 說的是另外的用途，故填besides。

【6】考查定語從句的用法。在復(fù)合句中修飾名詞或代詞的句子在充當(dāng)定語的就是定語從句，先行詞是the people，指人，則可以用who/whom，但后面的句子缺少主語，所以關(guān)系代詞充當(dāng)句子主語，whom只能充當(dāng)賓語，who既可做賓語也可作主語。故填who。

【7】考查固定搭配。In size是固定搭配，意為在尺寸或規(guī)模上。這里是指城市在規(guī)模上不斷發(fā)展壯大。同后文” industries increase in number”中的in number屬于同種用法。故填size。

【8】考查動詞過去式的用法。動詞過去式除了表示過去的動作之外，還可以表示一種狀態(tài)，這里的用法是表示水被污染的一種狀態(tài)。故填polluted。

【9】考查important的用法。The importance of為固定搭配，意為……的重要性。The和of之間應(yīng)填名詞。故填importance。

【10】考查連詞用法。前文” People are learning the _________ (important) of doing more to keep their rivers clean”人們認(rèn)識到保持他們的河流干凈的重要性，后文” they want to enjoy the benefits of this natural resource.”他們想要享受這種自然資源帶來的好處。前后文的意思是順承的，但后文也可以做前文的假設(shè)，故填if/because。
