5.C　hold up “举起;支撑”;keep up “维持，继续”;take up “拿起，开始从事，占据(时间或者空间)”;put up “举起”。此处take up“占据(时间或者空间)”。

6.A　本句考查虚拟语气及时态。由上句would have told可知是对过去事情的虚拟，但but后是指“过去我非常忙”，是事实，不用虚拟。

7.D　表示与过去事实相反的假设，从句谓语要用“had+过去分词”形式，而主句则用“would have+过去分词”形式。

8.A　anyway “不管怎样”;however “然而”;thus “这样，因此”; therefore “因此，所以”。选项A符合句意。

9.B　have power over sb. “对某人有支配权”;第二空为定语从句，先行词为anything，在从句中作want的宾语。

10.C　考查副词比较句型的用法。句意为：他的英语的确讲得好，但当然比不上当地人。在否定句中用so…as…。

11.C　“和……失去联系”固定短语有：lose contact with/out of contact with ;再根据时间状语for several years，应该使用延续性动词，故答案应为C。

12.C　考查动词短语辨析。account for意为“解释……的原因”。

13.D　考查非谓语动词。be accustomed to中的to是介词，后接动名词的否定结构not talking。

14.B　考查it的用法。it作形式宾语，that引导宾语从句。

15.C　 考查动词辨析。adjust (=arrange，put in order or agreement; make suitable or convenient for use) 强调，调节，使适应。本句中adjust是及物动词，意为“调节”。

Ⅱ.儿子第一次忘记带运动衣的时候他请求老师打电话通知“我”给他送过去，“我”拒绝了;儿子第二次忘记带运动衣的时候他自己打电话有礼貌的请求“我”给他送过去，“我”同意了。 是的，对孩子的教育，有时家长要学会运用“严厉的爱”。

20.C　根据“His … was genuinely sweet and unassuming(谦逊的)可推断此处儿子正在有礼貌地请求“我”帮他做事，故选C。Would you mind if…?是一个礼貌地请求他人做事的句型，符合语境。

21.B　根据genuinely sweet and unassuming可推断该空指儿子讲话的嗓音，故选B。

22.B　根据下文“我”帮他送衣服这一事实可推断“我”同意了，故选B。

23.A　根据he was not assuming anything可推断儿子有正确的态度，故选A。

24.D　此处应是老师告诉“我”儿子的表现，即向“我”解释儿子的行为，故选D。
