【分析】本题为英语句型转换题,包含对划线部分提问和同义句转换两类题型。解题思路:1. 对划线部分提问时,先根据划线内容确定对应疑问词,再调整句子语序,注意时态、人称和助动词的正确使用;2. 同义句转换需找到与原句语义一致的句型或短语,确保语法正确。
【解析】1. 划线部分为事物“the West Lake”,用疑问词What提问,原句be动词is提前,第一人称my变为第二人称your,故填What is;your。2. 划线部分为深度“about 10 metres deep”,用疑问词组How deep提问,故填How deep。3. 划线部分为不可数的重量“about 150 tons”,用疑问词组How much提问,主语a blue whale是单数,一般现在时借助助动词does,后面动词用原形weigh,故填How much does;weigh。4. 原句has表“有”,同义结构为There be句型,主语plenty of plants and animals是复数,be动词用are,故填There are。5. 划线部分为地点“the Great Wall”,用疑问词Where提问,原句是一般过去时,借助助动词did,后面动词用原形decide,故填Where did;decide。
【答案】1. What is;your 2. How deep 3. How much does;weigh 4. There are 5. Where did;decide
【知识点】特殊疑问句转换、同义句转换、There be句型

本题为英语选词填空题,解题思路如下:首先明确方框内每个单词的词性、词义;接着通读短文,结合空格处的语法要求(如词性、时态、单复数等)和上下文语境,选择合适的单词并进行正确变形,同时确保每个单词仅使用一次,最终使短文通顺完整。

2. 空格处强调“尤其在春天”,需用副词,方框中especially(尤其)符合,故填especially。
3. 空格处为谓语动词,主语they为复数,结合语境“测量水质”,用动词原形measure,故填measure。
4. 空格处需名词,结合“平均两米”可知指深度,deep的名词形式为depth,故填depth。
5. 空格处为谓语动词,主语Taihu Lake是第三人称单数,结合“包含鱼类”,用一般现在时的第三人称单数形式includes,故填includes。
6. 空格处为现在完成时结构“has + 过去分词”,结合“情况被改善”,用improve的过去分词improved,故填improved。
7. 空格处作主语,指“游客们”,需用visitor的复数形式Visitors,句首首字母大写,故填Visitors。
