2．in

3．aiming to promote cultural exchanges
【详解】考查非谓语动词和短语。分析句子可知，空处作定语修饰festival，用非谓语动词，表示“旨在做某事”用aim to do，逻辑主语festival与aim为主动关系，用现在分词，表示“促进文化交流”用promote cultural exchanges。故填aiming to promote cultural exchanges。
4．invite all the exchange students to join the club
【详解】考查动词、名词和非谓语动词。“邀请”作主句谓语，用动词invite，描述当前邀请的动作用一般现在时态，主谓一致，故谓语动词invite用原形；“所有的交换生”作宾语，用all the exchange students，“参加这个俱乐部”为宾语补足语，表示将来去做的事情，用动词不定式to join the club。故填invite all the exchange students to join the club。
5．about

8．Your parents and relatives are anxious for you to go to college.
【详解】考查时态、固定短语、名词。表示“你的”用代词your，作定语，修饰“父母和亲戚”，位于句首，首字母大写。表示“父母”用parents，表示“亲戚”用relative，亲戚不止一个，用复数形式，与parents并列，用连词and连接，共同作主语。表示“渴望某人做某事”用be anxious for sb. to do sth.，本句描述一般事实，句子时态用一般现在时，且主语为Your parents and relatives，be动词用are。表示“你”用you，作for的宾语。表示“上大学”用go to college，位于不定式符号to后，动词用原形。故翻译为Your parents and relatives are anxious for you to go to college.

10． were anxious to cook a delicious breakfast for their mother so anxious that tears of anxiety
【详解】考查时态、固定短语、固定句型。表示“渴望做某事”用固定短语be anxious to do，根据句意和第二句中的were可知，本句描述过去的动作和状态，故时态用一般过去时，谓语用过去式，且主语为The twins，be动词用were；表示“做饭”用cook，位于不定式符号to后，用动词原形；表示“一顿美味的早餐”用 a delicious breakfast，作cook的宾语；表示“为了”用介词for；表示“他们的妈妈”用their mother，作for的宾语。第二空中：表示“如此……以致……”用固定句型so... that...，其中that引导结果状语从句；表示“不安的”用形容词anxious，作表语；表示“焦急的泪水”用tears of anxiety，在that引导的结果状语从句中作主语。故填：①were anxious to cook a delicious breakfast for their mother；②so anxious that tears of anxiety。
11． with upon##on by##with on
【详解】考查固定短语。句意：这个外向的家伙以他的个性给面试官留下了深刻的印象。固定短语impress sb. with sth.或impress sth. upon/on sb.，表示“用某物给某人留下深刻印象”，第一空用with，第二空用upon或on。sb. be impressed by/ with sth.，表示“某人对某事印象深刻”，第三空用介词by或with。make an impression on sb.“给某人留下深刻印象”，第四空用介词on。故填①with；②upon/ on；③by/with；④on。

14．What impressed me most was
【详解】考查主语从句和时态。“给我印象最深的”作主语，写成主语从句，“使某人印象最深”为impress sb. most，由句中的were可知，句子描述过去发生的事，应用一般过去时，连接词在主语从句中作主语，指物，应用what来引导主语从句，翻译为what impressed me most，“是”为be动词，句子作主语，看成第三人称单数，be动词应用was，句首单词首字母大写，故填What impressed me most was。
15．concentration

17．was concentrated
【详解】考查时态语态。句意：他的注意力集中在他的实验上，因此没有时间陪伴家人。主语attention与谓语构成被动关系，根据后文had可知为一般过去时的被动语态，谓语用单数。故填was concentrated。
18． With his attention concentrated on his experiment, he had no time or his family. His attention concentrated on his experiment, he had no time for his family.
【详解】考查句型转换。句意：他的注意力集中在他的实验上，因此没有时间陪伴家人。根据第①题的题目要求可知，本句可用with复合结构作状语，即转换为with+宾语+宾补，用his attention作宾语，concentrate与his attention之间为被动关系，所以使用过去分词短语concentrated on his experiment作宾补，用so后面的句子作主句。根据第②题的题目要求可知，本句可用独立主格结构作状语，即用名词his attention+过去分词短语concentrated on his experiment来构成独立主格结构，用so后面的句子作主句。故答案为①With his attention concentrated on his experiment, he had no time or his family.②His attention concentrated on his experiment, he had no time for his family.
19． leave alone
【详解】考查固定短语和祈使句的肯定形式。句意：“管好你自己的事，别烦我。”那人不耐烦地说。根据句意以及提示可知，本空用固定短语leave... alone意为“不理，不管，不烦扰，不干涉”，根据空前的and和mind可知，本句用祈使句，所以第一空使用动词原形。故填①leave②alone。
20．left out
【详解】考查固定短语、动词语态。句意：记笔记，否则一些重要的要点将会被遗漏。结合句意，本空用固定短语leave out意为“遗漏，未包括”，与主语points为被动关系，所以此处使用过去分词，与空前的will be构成一般将来时的被动语态。故填left out。
21． left behind
【详解】考查固定短语和时态。句意：在五公里越野赛跑中，萨拉跑得太快了，很快就把我们甩在了后面。leave... behind是一个固定搭配，表示“把某人或某物远远甩在身后”，根据did和句意可知，本句描述过去的动作和状态，故时态用一般过去时，谓语用过去式。故填①left；②behind。
22．leave for
【详解】考查固定短语、时态。句意：明天早上8点在校门口集合，一起出发去营地。本空用固定短语leave for“动身去，到……地方去”，该句为一般将来时，此空位于we’ll之后，动词用原形。故填leave for。
23． What/How about What if So what
【详解】考查特殊疑问词和固定搭配。根据所给中文句子和英文翻译可知，①空处需翻译“怎么样”，此处为疑问句，所以可用what about或者how about提问，②空处需翻译“要是...怎么办”，此处是固定搭配：what if意为“如果…怎么办”，③空处需翻译“那又怎么样？”，此处为固定句型：So what？意为“那又怎么样？”。故填①what about或者how about，②what if，③So what。
24．What if we go out to visit
【详解】考查固定句型、时态、非谓语动词。表示“如果……怎么办”用固定句型what if，句首单词首字母大写。表示“我们”用we，作主语。表示“出去”用go out，what if引导的句子通常用于假设情况，比如讨论如果某个条件成立会发生什么，在这种情况下，使用一般现在时来表示将来，且本句主语为we，谓语用动词原形。表示“看，参观”用visit，用不定式，作目的状语。故填：What if we go out to visit。
25．enjoyable
【详解】考查形容词。句意：你一定会觉得这个艺术展很有趣，并爱上它。分析句子结构，空白处在句子中做宾语补足语表示属性，使用形容词，故填enjoyable。
26．addicted
【详解】考查形容词。句意：我发现我儿子沉迷于网络游戏，这让我怒不可遏。此处为find+宾语+宾补，且表示“沉迷的”应用形容词addicted。故填addicted。
27．found his children preparing
【详解】考查动词时态和现在分词。根据句意，此处表示“发现他的孩子正在准备”为“find+宾语+宾补”结构，结合下文中的谓语动词tiptoed可知，此处使用一般过去时，所以find应为动词过去式作谓语，表示“他的孩子们”应为his children作宾语，表示“准备”应为prepare，与宾语之间为主动关系，且表示动作正在进行，所以此处使用现在分词形式作宾补。故填found his children preparing。
28．I find it difficult to adapt to the new school life
【详解】考查短语和it用法。主语为I；表示“发现做某事很难”句型为find it difficult to do sth.，it作形式宾语；动词不定式做真正宾语。表示“适应”短语为adapt to；表示“新的学校生活”短语为the new school life，根据后文ask可知为一般现在时。故填I find it difficult to adapt to the new school life。
