【題目】 It was so noisy that we hear ourselves speak.

A. couldn’t B. shouldn’t

C. mustn’t D. needn’t

【答案】A

【解析】

試題分析：句意：太吵了，以致我們不能夠聽到我們在說什么？A的意思是不能，B的意思是不應(yīng)該，C的意思是禁止，D的意思是不需要。該題用到了一個so +形容詞+ that的句式，做題時應(yīng)該正確理解句意及這個句式的用法。正確理解這是表達不能還是表達其他的東西。must只能用于肯定句，用于否定句表示禁止，這一點尤其要注意因為往往會出錯。如果表示一種可能往往是can 的形式（過去時態(tài)使用could）
