　　【導(dǎo)師點(diǎn)評(píng)】

　　文章以在陌生的城市找名勝為例，說明了解決數(shù)學(xué)最重要的是先找出一條通往答案的路徑。

　　【答案簡析】

　　1.C。下文表明：你要去的是一個(gè)一點(diǎn)兒都不熟悉的城市，說明以前沒有去過。故選have never visited。

　　2.D。show意為“帶領(lǐng)某人參觀某地”或“向某人展示某物”;tell sb. about sth. 意為“告訴某人關(guān)于……的情況。根據(jù)下文可知tell為正確選項(xiàng)。

　　3.A。文章表明：聽了別人的介紹后，你對(duì)城市的名勝開始有了一些初步的印象。故選begin。

　　4.B。根據(jù)文意，你對(duì)名勝的概況只是聽說而已，對(duì)名勝的具體位置及如何找到所指的名勝不太清楚。故選clear。

　　5.C。指代上文出現(xiàn)的interesting places應(yīng)用them。

　　6.A。根據(jù)句意，前半句是后半句的條件狀語從句，應(yīng)用if引導(dǎo)。

　　7.D。show sb. sth.意為“把……給某人看”，合符文意，為正確選項(xiàng)。

　　8.B。根據(jù)地圖上的位置，你會(huì)毫不費(fèi)力地找到想去的地方。故選no。

　　9.B。本文是講如何在一個(gè)陌生的城市里找到目的地，而不是找去某個(gè)城市的路。故選in。

　　10.A。做數(shù)學(xué)題時(shí)，你肯定要對(duì)題目中所給的信息進(jìn)行思考。故應(yīng)選thought over。

　　11.D。the road to the answers意為“解決問題的路徑”，to為正確選項(xiàng)。

　　12.A。根據(jù)上文列舉的根據(jù)地圖找名勝的例子可知，做數(shù)學(xué)題目也需要“地圖”。故應(yīng)選need to have。

　　13.B。這里應(yīng)該用動(dòng)詞不定式to help you find your way作目的狀語才合符句意。

　　14.A。try one’s best to do sth.意思是“盡某人最大的努力去做某事”，為正確選項(xiàng)。

　　15.C�！發(fā)ead sb. to某地”意思是“引導(dǎo)某人到達(dá)某地”。
