() 1.At first I regretted ______ them to stay, but we soon became great friends.
A.to invite
B.invited
C.to have invited
D.inviting

D

本题考查非谓语动词。regret to do sth. 表示“对要做的事感到遗憾”，regret doing sth. 表示“对做过的事感到遗憾、后悔”。根据句意“起初我后悔邀请他们留下来，但我们很快就成了好朋友”可知，这里表示对已经做过的事情感到后悔，应该用 regret doing sth. 的结构。A 选项 to invite 是动词不定式，不符合语境；B 选项 invited 是过去式或过去分词，不能直接用在 regret 后；C 选项 to have invited 是动词不定式的完成式，也不符合语境；D 选项 inviting 是动名词，符合 regret doing sth. 的结构。

() 2.Miss Zhao is very helpful. She often helps us ______ we are in trouble.
A.whatever
B.wherever
C.whenever
D.however

C

本题考查连词的用法。题干的意思是：“赵老师非常乐于助人。她经常帮助我们______我们处于困境中。”选项A，whatever，意为“无论什么”，通常用于引导名词性从句，表示“无论发生什么事”。但在此题中，我们需要一个表示时间的连词，因此whatever不符合语境。选项B，wherever，意为“无论在哪里”，它通常用于引导地点状语从句。但题干中的语境是表示时间，即“无论何时我们处于困境”，所以wherever也不适用。选项C，whenever，意为“无论何时”，它用于引导时间状语从句，表示“在任何时候”。在此题中，它恰好符合语境，即“赵老师无论何时我们处于困境都会帮助我们”。选项D，however，意为“无论如何”，它通常用于引导让步状语从句，表示“不管怎样”。但题干中的语境是表示时间，因此however也不符合。

() 3.—It's a pity that I can only stay here for two days ______.
—Why not stay for another day? I know you have three days off.

A.at first
B.at last
C.at least
D.at most

D

根据答句“Why not stay for another day? I know you have three days off.”可知，对方有三天假期，却只待两天，强调“最多”两天。A.at first起初；B.at last最后；C.at least至少；D.at most最多。D符合语境。

() 4.—Could you tell me how I can improve my English?
—Sure. ______, you could speak it as much as possible.

A.After all
B.In the end
C.By the way
D.First of all

D

题目询问提高英语的方法，回答中提到“you could speak it as much as possible”是提高英语的一个具体建议。分析选项：
A. After all 表示“毕竟”，通常用于强调某个事实或原因，不符合语境。
B. In the end 表示“最后”，通常用于描述事情发展的结果，不符合语境。
C. By the way 表示“顺便说一下”，用于转换话题或添加额外信息，不符合语境。
D. First of all 表示“首先”，用于列举建议或步骤的开头，符合语境，表示这是提高英语的一个初步建议。

() 5.—How long can this mobile phone last?
—If you use it ______, it may work for you for quite a few years.

A.smoothly
B.completely
C.properly
D.widely

C

本题考查副词词义辨析。根据问句“How long can this mobile phone last?”（这部手机能用多久？）以及答句“it may work for you for quite a few years”（它可能会为你工作好几年），可知此处表达的是如果手机使用得当，就能用很长时间。A选项“smoothly”意为顺利地；B选项“completely”意为完全地；C选项“properly”意为适当地、正确地；D选项“widely”意为广泛地。结合语境，只有C选项符合题意。
