Could 解析:根据 “when you were nine years old” 可知是询问过去的能力,can 的过去式是 could,句首首字母大写。 6. shopping 解析:from 是介词,后接动词 -ing 形式,shop 的 -ing 形式是 shopping。 7. unfair 解析:根据常识,考试作弊是不公平的,fair 的反义词是 unfair,意为 “不公平的”。 8. folded 解析:根据语境,此处描述的动作已发生,用一般过去时,fold 的过去式是 folded。 9. fairness 解析:of 是介词,后接名词,fair 的名词形式是 fairness,意为 “公平,公正性”。 10. developing 解析:根据 “now” 可知,句子用现在进行时,结构为 be + 动词 -ing,develop 的现在分词是 developing。 二、根据首字母及汉语提示写单词 1. folds 解析:根据 “carefully puts it into his bag” 及首字母 f,可知是 “折叠” 纸,主语 He 是第三人称单数,一般现在时中动词用第三人称单数形式 folds。 2. depending 解析:be used to doing sth. 表示 “习惯于做某事”,根据 “cannot be independent at all” 可知是依赖父母,depend on 表示 “依赖”,depend 的 -ing 形式是 depending。 3. swept 解析:根据 “and then took out the litter” 及首字母 s,可知是 “扫地”,sweep the floor 表示 “扫地”,and 连接并列动词,took 是 take 的过去式,所以 sweep 也用过去式 swept。 4. floor 解析:“地板” 的英文是 floor。 5. stress 解析:“精神压力” 的英文是 stress,是不可数名词。 6. waste 解析:根据 “Don’t” 及 “your time on computer games” 和首字母 w,可知是不要在电脑游戏上浪费时间,waste 表示 “浪费”,Don’t 后接动词原形。 7. fold 解析:根据 “her clothes” 及首字母 f,可知是 “叠衣服”,fold 表示 “折叠”,can 是情态动词,后接动词原形。 8. neighbors 解析:“邻居” 的英文是 neighbor,前面有 all 修饰,用复数形式 neighbors。 9. fair 解析:“公平的” 英文是 fair。 10. provides 解析:“提供” 的英文是 provide,主语 The hospital 是第三人称单数,一般现在时中动词用第三人称单数形式 provides。 三、单项选择 1. B 解析:invite sb. to... 是固定搭配,意为 “邀请某人去……”,根据 “last night” 可知用一般过去时,invite 的过去式是 invited。 2. B 解析:as...as... 中间用形容词或副词原级,此处修饰动词 speaks,用副词 well,意为 “王伟说英语和杨澜一样好”。 3. D 解析:look at 意为 “看”;look out 意为 “小心”;look for 意为 “寻找”;take care of 意为 “照顾”。根据 “My parents are out.” 可知要照顾弟弟,故选 D。 4. D 解析:take away 意为 “拿走”;take out 意为 “取出”;take up 意为 “占据,开始从事”;take care of 意为 “照顾”。根据 “my pet bird when I’m on vacation” 可知是请求对方照顾宠物鸟,故选 D。 5. A 解析:mind doing sth. 是固定搭配,意为 “介意做某事”,所以用 moving。 6. B 解析:“Neither + 助动词 + 主语” 表示 “某人也不……”,用于否定情况;“So + 助动词 + 主语” 表示 “某人也……”,用于肯定情况。上句说 “去年暑假我哪儿也没去,真无聊!”,是否定情况,所以用 Neither did I,表示 “我也没去”。 7. C 解析:Could you please...? 是表示请求的常用句型,意为 “请你…… 好吗?”,must 意为 “必须”;need 意为 “需要”;should 意为 “应该”,均不符合语境。 8. B 解析:Could I...? 表示请求,肯定回答用 Yes, you can. ;根据语境,“你可以用我的自行车,但你必须保持它干净”,must 表示 “必须”。 9. A 解析:Could I...? 用于委婉地提出请求,意为 “我可以…… 吗?”;Must 意为 “必须”;Need 意为 “需要”;Will 用于一般将来时或表示意愿,此处用 Could 更合适。 10. C 解析:Could you please...? 的否定回答常用 Sorry, I can’t. 因为后面说 “我必须为数学考试学习”,所以是拒绝请求,A 选项中 couldn't 常用于一般过去时的否定回答。 四、完成句子 1. depend on 2. cleaned the living room 3. make her bed 4. as soon as 5. all the time; angry with 五、句型转化 1. not move 解析:Could you please do sth.? 的否定形式是 Could you please not do sth.? 2. Sorry, I can’t. 3. less hard - working 解析:“Tara isn’t as hard - working as me.” 表示 “Tara 不如我努力”,其同义句可以用比较级 “Tara is less hard - working than me.” 4. didn’t do 解析:一般过去时的否定句,借助助动词 didn't,后接动词原形,原句中 did 是 do 的过去式,所以否定句为 didn't do。 5. Could you please 解析:Would you like to do sth.? 与 Could you please do sth.? 都可表示请求,意思相近。 学科网(北京)股份有限公司 $$
