4.C
点拨：考查动词短语的辨析。句意为“那个男孩的腿在车祸中严重受伤，医生只好切掉它们”。cut up意为“切碎”；cut out“剪裁；剪下”；cut off“切掉；切断”；cut down“砍倒；缩减”。根据句意可知用 cut off.故选C.
5.A
点拨：考查副词的辨析。句意为“李雷上周末没有玩电脑游戏。相反，他在一家养老院做志愿者”。Instead“相反，而是”；Certainly“当然”；Though“尽管”；Gradually“逐渐地”。前后句之间有转折含义，故选A.

点拨：用句意分析法。句意为“约翰擅长运动。每周日早上8点，他要么爬山，要么踢足球”。题干语境提示at 8:00,在同一时间点不可能同时做两项运动，故选either...or...“要么····要么。。。。。”，故选B.
2.A
点拨：用短语辨析法。句意为“－露西，昆明的天气如何？－既不热也不冷。因此昆明被称为“春城＇”。neither. nor...既不也不；not only...but also...不但··而且·;either...or...或者··或者··;both...and...不仅···而且。
根据“So Kunming is called 'the Spring City””可知昆明的天气既不热也不冷。
3.C
点拨：考查连词辨析。neither...nor表示“既不·也不。。”；either...or表示“或者···或者·..”；not only...but also 表示“不但····而且·”；too...to表示“太·而不能··.”。句意为“现在抖音不仅在年轻人中受欢迎而且在老年人中也受欢迎”。故选C.

点拨：do harm to 和 be harmful to 具有相同的意义，意思是“对······有害”。
5.endangered; dangerous; in danger
6.danger
点拨：句意为“现在许多野生动物都处在危险中。我们应该保护它们”。分析句子可知，介词后面需要跟一个名词作宾语，dangerous的名词形式是 danger, in danger处在危险中，固定短语，故答案是 danger.
7.A

2.D

4.B
