【解析】

這是一篇說明文。文章介紹了四川省著名的水利工程-都江堰。都江堰始建于古代，主要目的是保護下游免受水患。

【1】考查冠詞。由空格后的形容詞最高級oldest判斷出此處應該用定冠詞the。故填the。

【2】考查可數(shù)名詞的數(shù)。根據空格前的fifty可判斷出此處用city的復數(shù)形式。故填cities。

【3】考查定語從句關系詞。句意：古代，都江堰現(xiàn)在所處的地方常常會遭受從岷江溢出的洪水侵襲。分析句子結構可知此處是定語從句，先行詞是the region指物，關系詞在句中充當in的賓語，介詞之后不能用關系詞that，故用關系代詞which。故填which。

【4】考查非謂語動詞。句意：同上。分析句子結構可知，此處應該用非謂語動詞作后置定語，邏輯主語和cause是被動關系，故用過去分詞。故填caused。

【5】考查并列連詞。句意：最簡單的方式是修建大壩，但這樣會毀掉岷江。分析句子結構可知此處應填連詞；根據句意可知，前后部分是轉折意義，故用并列連詞but。故填but。

【6】考查副詞。句中的flowing是現(xiàn)在分詞，應該用副詞修飾，free的副詞形式是freely。故填freely。

【7】考查固定句型。句意：更妙的是，多余的水可以被引入干燥的成都平原，使得這個平原適宜耕種。根據固定句型make sth/sb+賓語補足語（名詞，形容詞，分詞，介詞短語）可知此處應該用suit的形容詞形式suitable/suited。故填suitable/suited。

【8】考查時態(tài)和語態(tài)。分析句子結構可知，此句缺少謂語動詞，主語“Dujiangyan”和admire之間是被動關系，故用被動語態(tài)，由today判斷時態(tài)為一般現(xiàn)在時，主語是三單形式。故填is admired。

【9】考查介詞。句意：不像現(xiàn)在那些由距墻隔斷水流的大壩，都江堰的水可以自然而然地流過岷江。根據句意判斷，此處應該用介詞like的否定形式是unlike。故填unlike。

【10】考查固定句型。根據固定句型：make it + adj +for sb/sth to do 使得做某事對于某人來說是…的，可知此處應該用不定式形式。故填to exist。
