30． made decision
【详解】句意：布莱克先生决定送儿子去中国。根据“decided”可知，此句时态是一般过去时，因此第一空动词用一般过去式；再者根据固定搭配“决定做某事：decide to do sth./make a/the decision to do sth.”可知，made；decision符合句意。故填made；decision。

51． It’s that
【详解】句意：黑衣服适合胖人穿。根据句意，本句可改为“胖人穿黑衣服是合适的”，改写为it is/was+adj.+that从句，原句为一般现在时，所以用it is，缩写为it’s，句首单词首字母大写，形容词不变。故填It’s；that。
52． so couldn't / didn't
【详解】句意：她害怕得说不出话来。
根据句意理解可知，这里表达的是“如此害怕以至于不能说话”，英语是so…that，引导的是结果状语从句，而主句用的是过去时，所以从句也要用过去时，变成否定可以用助动词didn’t或者用情态动词couldn’t，故答案为so，couldn’t/ didn’t。
53． there was
【详解】句意：因为外面没有灯光，感觉就像午夜。as表示因为，引导原因状语从句，there be句型，表示有，根据felt可知，此处用一般过去时，主语light是不可数名词，因此谓语用第三人称单数形式was，故填there；was。
54． because of
【详解】句意：我们没有去公园因为下雨了。原句用“because”引导原因状语从句，可用“because of+名词”代替。表达“因为下雨”用“because of the rain”。故填because；of。
55． if has
【详解】句意：Tom的妈妈经常问Tom：“你完成你的家庭作业了吗？”原句是一个直接引语，同义句中将直接引语变为了宾语从句，if是引导词，意为“是否”；从句是现在完成时，主语为he，故第二个空应填has。故填if；has。
56． come/be true/achieved/realized hold on to
【详解】句意：只要我们坚持我们的梦想，终有一天我们可以实现我们所有的梦想。根据题干，句子是由as long as引导的条件状语从句，同义句中，主句处需要补充“实现”，短语come true或动词achieve和realize均可表示“实现”，前者的主语是物，后两者的主语是人，而主句主语为dreams，用come true时，可直接填写，用achieve或realize时，需要被动语态，结构为be+过去分词；从句中需补充“坚持”，短语hold on to表示“坚持”，且从句时态应用一般现在时。故填come/be；true/achieved/realized；hold；on；to。
57． It to walk
【详解】句意：饭后散步很有帮助。根据题干可知，同义句的结构为“It is+adj+to do sth+其他”，表示“做某事是怎么样的”；it在句中作形式主语并大写句首字母，动词不定式to walk“散步”作真正的主语。故填It；to；walk。
58． if/whether was
【详解】句意：他说：“你对英语感兴趣吗？”根据题干所给内容可知，需把直接引语变为间接引语，变换后是一个宾语从句；原句用一般疑问句提问，引导词应填if/whether“是否”；主句是过去时，从句也用过去的时态，主语是I，因此be动词用was。故填if/whether；was。
59． Unless keep
【详解】句意：坚持练习，你会提高你的英语技能。原句可表达为“除非你坚持练习，否则你不能提高你的英语技能”，unless“除非”，引导条件状语从句，从句用一般现在时，主语you是第二人称，动词用原形，故填Unless；keep。
60． Work harder
【详解】句意：如果你不更努力学习，你将考试不及格。在英语中“祈使句+or+ 简单句”可以和含有“if”引导的条件状语从句 (否定句) 的复合句转换。所以此处应填祈使句，故填Work；harder。
61． What/How exploring
【详解】句意：为什么不步行去长城探险？提建议的句式可用“What/How about doing sth.”，表示“做某事怎么样”，动名词作宾语，explore“探险”。故填What/How；exploring。
62．with
【详解】句意：她正忙着做数学题。原句中使用了句型be busy doing sth.“忙于做某事”，同义短语是be busy with...，后跟名词。故填with。

【详解】句意：玩鼓对我来说是很容易的。根据句意可知，变成同义句，以It作形式主语，考查句型It is + adj + for sb to do sth，对某人来说做某事是……的。故答案是(1). is (2). easy (3). for (4). me (5). to (6). play
64． get ready
【详解】句意：让我们做好准备。空格处缺“做准备”，prepare for=get ready for“做准备”，动词短语，let sb do sth.“让某人做某事”，空格处接动词原形。故填get；ready。
65． Why don’t you finish
【详解】句意：为什么不先完成作业呢？Why not do sth. =Why don’t you do sth. 为什么不……呢？ 故填Why；don’t；you；finish。
66． It seems
【详解】She seems very excited.表示她似乎非常激动。It seems that +从句,表示“似乎……”，故此处为It seems。
67． if don’t get up
【详解】句意：如果你不早起，你就赶不上早班车。改为同义句，可以改为由if引导的条件句，从句用一般现在时，you后get up变为don’t get up，意为“如果你不早起，你就赶不上早班车”。故填if；don’t；get；up。
68． old enough to so that they can’t
【详解】句意：孩子们太小了，音乐会没完就坐不住了。too...to...“太……而不能……”，可与not...enough to...结构互相转换，太小了，也就是说孩子们不够大，故用not old enough to；也可以转换为so...that...结构，so young that they can’t表示“如此小以至于他们不能……”。故填old enough to；so；that they can’t。
69． deal with
【详解】句意：我相信你能自己解决这个问题。can是情态动词，后接动词原形；solve“解决，处理”，动词，相当于deal with。故填deal；with。
70． if don’t
【详解】句意：除非你努力学习，不然你得不到好成绩。“unless 除非”，引导条件状语从句，相当于“if…not”；由于主语是“you”，且从句时态为一般现在时，所以“work”的否定在“work”前加do not，即don’t，故填if；don’t。
71． If isn't
【详解】句意：除非课堂上有最新信息，否则学生不会感兴趣。原句使用unless引导条件状语从句，可替换为“if...not”，information是不可数名词。原句中含有be动词is，此处可缩写为isn't。故填If；isn't。
72． because of
【详解】句意：他开会迟到了，因为他遇上了交通堵塞。题干中的句子是because引导的原因状语从句，the traffic jam为名词性短语，为使上下句意思不变，需要介词词组because of。
73． so that
【详解】句意：Jim学习足够努力，通过了考试。考查so…that…引导的结果状语从句。其同义句句意为：Jim学习如此努力，以至于他通过了考试。so...that如此……以至于，引导结果状语从句。故填so；that。
74． helpful of
【详解】句意：艾米经常为慈善机构筹款。她乐于助人。题目要求合并为一句，此处使用句型“It’s adj. of sb to do sth”表示“某人做某事是怎么样的”，helpful“乐于助人的”，说明人品质的形容词。故填helpful；of。
75． so clever
【详解】句意：莉莉是个聪明的女孩，她能解决这个问题。such...that... = so...that... “如此……以至于……”。so修饰形容词或副词。故填so；clever。
76． to learn/study
【详解】句意：每个星期天我都帮助我弟弟学英语。learn/study学习；help sb. with sth.在某方面帮助某人，义同help sb. (to) do sth.“帮助某人做某事”，都是固定结构。结合题干有两个空，可知不省略不定式符号to，故填to; learn/study。
77． he would
【详解】句意：迪克说：“我会列一份购物清单。” 结合题干，要变为间接引语，本句为宾语从句。根据said可知，主过从必过，从句用过去的某种时态，所以will变为would，he指代Dick。故填he；would。
78． patient enough
【详解】句意：他是如此的耐心，等了她三个小时。so+adj+that表示“如此……以至于”，可用adj+enough to do sth“有足够……做……”替换。patient enough“足够的耐心”。故填patient；enough。
79． so that
【详解】句意：我轻轻地走进房间，以免惊扰熟睡的婴儿。in order to“为了”，此时可以用so that“为了，以便”来替换，故填so；that。
80． how got
【详解】句意：我的老师问蒂姆:“你和别人相处得怎么样？”原句是直接引语，根据语境和题干可知改为how引导的宾语从句，需用陈述句语序；宾语从句遵循主过从过原则，主句动词asked是一般过去时，可知从句动词get用其过去式got，故填how; got。
