【解析】

1. located on.是固定搭配，意為位于。因?yàn)閏ities不是人，不能執(zhí)行動(dòng)作，所以要用被動(dòng)語態(tài)。同時(shí)還有be located in/at的用法。故填located。

2. every/each在這里作形容詞，意為每一個(gè)，由” and almost 3. country has at least one river flowing through it”可知，這里既不能填all，因?yàn)榕calmost不能同時(shí)使用，也不能填no/none，因?yàn)槟遣环�合�?shí)際情況。故填every/each。

4. an important part in是一個(gè)固定搭配，意為在……扮演一個(gè)重要角色。同時(shí)也考查冠詞用法。因?yàn)閕mportant開頭的元音字母發(fā)元音，不能填a，故填an。

5. Since the beginning of history, people 6. (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(jìn)行運(yùn)輸。而到現(xiàn)在人們也還是在使用河流，故是從過去某時(shí)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。

7. rivers give water to drink, water for crops, and chances for fun and recreation for the people 8. live along their banks.” 說的是另外的用途，故填besides。

9. 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。

10. 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。

11.

12. 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。

13. People are learning the _________ (important) of doing more to keep their rivers clean”人們認(rèn)識(shí)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。

考點(diǎn)：考查語法知識(shí)。
