解析

【分析】
解题思路:首先明确方框内的单词为tour、gain、melt、complete、freeze、wheel;然后分析每个句子的语境、语法结构(时态、语态、所需词性等),结合单词的变形规则,选择合适的单词并调整为正确形式。
【解析】
1. 句意:太阳很热,地上的雪正在融化。此处需用现在进行时,结构为“be+现在分词”,故将动词melt变为现在分词melting。
2. 句意:随着旅游业的发展,甘肃有很多游客。此处需表达“旅游业”,名词tour意为“旅行”,转换为名词tourism(旅游业)符合语境。
3. 句意:因为外面零下三十度,河湖被冻住了。此处为被动结构“be+过去分词”,动词freeze的过去分词为frozen,表“被冻住的”,符合句意。
4. 句意:多亏了整个团队的努力,项目按时完成。主语project是动作complete的承受者,需用被动语态;动作发生在过去,故用一般过去时的被动语态,即was completed。
5. 句意:轮子发明后,旅行变得更快更舒适。此处指“轮子”这类事物,可数名词wheel需用复数形式wheels。
6. 句意:虽然我没通过面试,但我获得了很多经验。动作发生在过去,需用动词gain的过去式gained。
【答案】
1. melting 2. tourism 3. frozen 4. was completed 5. wheels 6. gained

【分析】
要解决这道语法填空题,需结合语境判断时态和语态:
1. 第一空:句意强调伟大发明对现在的影响,用现在完成时,主语是复数,故用have changed;
2. 第二空:it指代轮子,与“发明”是被动关系,且动作发生在过去,用一般过去时的被动语态,故填was invented;
3. 第三空:手机与“使用”是被动关系,时间为现在,用一般现在时的被动语态,故填are used;
4. 第四空:人们与“允许”是被动关系,描述现在的情况,用一般现在时的被动语态,故填are allowed;
5. 第五空:事情与“做”是被动关系,情态动词can后接被动结构,故填be done。
【解析】
1. 第一空:考查现在完成时,句意为“伟大的发明已经改变了世界”,强调过去动作对现在的影响,主语Great inventions为复数,故填have changed;
2. 第二空:考查一般过去时的被动语态,it(指代the wheel)与invent是被动关系,且发明轮子是过去的动作,主语为单数,故填was invented;
3. 第三空:考查一般现在时的被动语态,mobile phones与use是被动关系,时间状语为Today,主语为复数,故填are used;
4. 第四空:考查一般现在时的被动语态,people与allow是被动关系,描述现在的常态,主语为复数,故填are allowed;
5. 第五空:考查含情态动词的被动语态,things与do是被动关系,情态动词can后需接“be + 过去分词”结构,故填be done。
【答案】
1. have changed 2. was invented 3. are used 4. are allowed 5. be done
【知识点】
被动语态;现在完成时;一般过去时
【点评】

【解析】
1. 原句是一般过去时被动语态,改一般疑问句将be动词was提前,故填Was; invented;
2. 含情态动词should的被动结构为should + be + 过去分词,clean的过去分词是cleaned,故填be cleaned;
3. 对划线部分“paper”提问用疑问词what,再将be动词is提前,故填What is;
4. 一般疑问句Were...?的肯定回答为Yes, they were,故填Yes; were;
5. 一般现在时主动改被动,主语rice为不可数名词,be动词用is,grow的过去分词是grown,故填is grown。
