I can sing too.(P70)

I like apples, and my sister likes apples, too. 我喜欢苹果,我妹妹也喜欢苹果。
Are you a student, too? 你也是一名学生吗?
She, too, wants to go to the park. 她也想去公园。

I like apples, and my sister likes apples, too. 我喜欢苹果,我妹妹也喜欢苹果。
Are you a student, too? 你也是一名学生吗?
She, too, wants to go to the park. 她也想去公园。

She is also a teacher.
她也是一名教师。is是be动词,also放在其后
They can also speak English.
他们也会说英语。can是情态动词,also放在其后
3. either:用于否定句中,且通常位于句末,其前一般用逗号隔开。
I don't like coffee, and my brother doesn't like it, either.
我不喜欢咖啡,我哥哥也不喜欢。
记忆口诀:肯定句中用too、also,句末逗号跟too,行为之前also走 ;否定句里用either,句末逗号别放错 。

高频易错点04
Look, This is my picture!(P71)
look v.看,为不及物动词,后面不能接宾语,常常单独使用,以引起对方的注意。
Look! This is my grandpa.
看!这是我的爷爷。
易错点提示
look 和 look at的区分
(1)look 与 look at 都可以表示“看……”
(2)look at 是由动词 look 和介词 at 组成的短语,后面可以接宾语,侧重“看”的内容。
(3)表达看某人/某物时句型:Look at...,句型结构:Look at + 某人/某物。
★易错点提醒:句中 look 意为“看”,强调动作。当表示看具体的人或事物时,look 后面要接 at。
Look! The girl is my sister. 看!那个女孩是我的姐姐。
Look at my new skirt. 看我的新裙子。

易错点提示

参考答案

1. 答案:xyz
解析:根据26个字母的大小写对应规则,“X”的小写是“x”,“Y”的小写是“y”,“Z”的小写是“z” 。
2. 答案:PICTURE
解析:“picture”中每个字母对应的大写形式分别为“P”“I”“C”“T”“U”“R”“E”,按照顺序组合起来即可。
3. 答案:dance
解析:“DANCE”中每个字母对应的小写形式分别为“d”“a”“n”“c”“e”,将其转换为小写并按顺序书写。

5. 答案:YZ
解析:“y”的大写是“Y”,“z”的大写是“Z” 。
二、单项选择题
答案:BABBA BABCA
1. 答案:B
解析:句子主语“My brother”是第三人称单数,在一般现在时中,动词“want”要用第三人称单数形式“wants”;“want to do sth.”为固定结构,意为“想要做某事”,所以这里用“wants to” 。
2. 答案:A
解析:“too”“also”“either”都有“也”的意思 。“too”常用于肯定句和一般疑问句,通常位于句末,其前一般用逗号隔开,有时也可以放在句中(主语之后,行为动词之前);“also”较正式,一般用于肯定句中,位于行为动词之前,be动词、助动词或情态动词之后;“either”用于否定句中,且通常位于句末,其前一般用逗号隔开。本句是肯定句,且“也”在句末,所以用“too” 。
3. 答案:B
解析:“look”是不及物动词,后面不能接宾语,常单独使用以引起对方注意;“look at”是由动词“look”和介词“at”组成的短语,后面可以接宾语,侧重“看”的内容 。本句中有宾语“the nice fox”,所以用“look at”,且“please”后接动词原形。
4. 答案:B
解析:“buy sth. for sb.”是固定搭配,意为“为某人买某物”,这里表示妈妈为“我”买新裙子,所以用“for” 。“buy sth. to sb.”表述错误;“at”不符合该语境。
5. 答案:A
解析:句中“play”是动词原形,“is”后不能直接接动词原形;“do”作为助动词时,在一般现在时中,当主语是第三人称单数时,要用“does”,且“do”后也不直接接动词原形;“can”是情态动词,后接动词原形,“She can also play the piano well.”表示“她也能把钢琴弹得很好” 。
6. 答案:B
解析:“want”表示“想要”时,常见用法是“want to do sth.”,即“想要做某事”,所以这里用“to do” 。“want do”和“want doing”不符合“want”的用法规则。
7. 答案:A
解析:“send sth. to sb.”是固定搭配,意为“把某物寄给/送给某人”,这里是把信送给老师,所以用“to” 。“send sth. for sb.”意思是为某人发送某物(强调目的是为某人),不符合语境;“with”没有这种用法。
8. 答案:B
解析:“Look”单独使用时,可引起对方注意,后面不接宾语;“Look at”后要接宾语;“Looking”是“look”的现在分词形式,不能直接用于句首引起注意 。本句中没有宾语,且要引起对方注意看墙上的画,所以用“Look” 。
9. 答案:C
解析:本句是否定句,且“也”在句末,所以用“either” 。“too”用于肯定句末;“also”用于肯定句中,行为动词之前,be动词、助动词或情态动词之后。
10. 答案:A
解析:“want sb. to do sth.”是固定搭配,意为“想要某人做某事”,所以这里用“to” 。“want sb. do sth.”和“want sb. doing sth.”不符合“want”的用法规则。
三、找出问句相应的答句,将序号填在括号内
答案:BCEDA
1. 答案:B
解析:问句询问“你能为你的家人做什么”,答句应回答具体能做的事情,B选项“我能擦桌子和洗碗”符合要求 。
2. 答案:C
解析:问句是“你想唱首歌吗”,是一般疑问句,用“Yes”或“No”回答,C选项“是的,我想。唱歌让我开心”符合回答格式且内容匹配 。
3. 答案:E
解析:问句问“你想把这张卡片寄给谁”,E选项“我想把它寄给我最好的朋友莉莉”回答了寄卡片的对象,符合语境 。
4. 答案:D
解析:问句问“你能为我画一幅画吗”,D选项“当然!我可以为你画一只漂亮的狐狸”表示同意并说明了画的内容,符合逻辑 。
5. 答案:A
解析:问句是“这个玩具是给你弟弟的吗”,是一般疑问句,A选项“是的,它是。他非常喜欢玩具”,用“Yes”回答,且说明了玩具是给弟弟的原因,符合要求 。
四、情景选择
答案:ABBBA ABBBA
1. 答案:A
解析:“I can dance too.”表示“我也会跳舞”,“too”用于肯定句末表示“也”,符合语境;“I also can dance.”语序错误,“also”应放在行为动词前;“I can’t dance either.”意思是“我也不会跳舞”,与想表达的意思相反 。
2. 答案:B
解析:“Look at my new picture!”中“look at”后接宾语“my new picture”,表示“看我的新画”,符合请朋友看画的语境;“Look my new picture!”错误,“look”后接宾语要加“at”;“Looking at my new picture!”是现在分词短语,不能单独构成句子用于邀请别人看画 。
3. 答案:B
解析:“I want to buy a birthday gift for my mom.”中“buy sth. for sb.”是固定搭配,意为“为某人买某物”,该句表达“我想为我妈妈买一份生日礼物”,符合语法和语境;“I want to buy a birthday gift to my mom.”表述错误;“I want buy a birthday gift for my mom.”中“want”后接动词要用“to do”形式,缺少“to” 。
4. 答案:B
解析:“I can sing for them.”中“for”表示“为了”,“为他们唱歌”用“sing for them”,符合回答“能为家人做什么”的语境;“I can sing to them.”中“sing to”通常表示“对着……唱歌”,强调对象;“I can sing with them.”表示“和他们一起唱歌”,意思不符 。
5. 答案:A
解析:“Look at the bird in the tree!”中“look at”后接宾语“the bird in the tree”,用于让别人看树上的鸟,符合语境;“Look the bird in the tree!”错误,“look”后接宾语要加“at”;“Look, the bird in the tree!”中“look”单独使用,没有明确让别人看的对象,表述不准确 。
6. 答案:A
解析:“My sister wants to go to the park too.”中“too”用于肯定句末表示“也”,且“want to do sth.”结构正确,表达“妹妹也想去公园”;“My sister also want to go to the park.”中“want”应使用第三人称单数形式“wants”;“My sister wants to go to the park either.”中“either”用于否定句末,不符合本句肯定句的语境 。
7. 答案:B
解析:“Please bring the book to the teacher.”中“bring sth. to sb.”是固定搭配,意为“把某物带给某人”,表示把书带给老师,符合语境;“Please bring the book for the teacher.”中“bring sth. for sb.”意思是为老师带来某物(强调目的是为老师),但没有“带给”的意思;“Please take the book for the teacher.”中“take”表示“带走”,与“带给老师”的语境不符 。
8. 答案:B
解析:“I don’t like apples, and my brother doesn’t like them either.”中“either”用于否定句末表示“也”,符合“我不想吃苹果,弟弟也不想吃”的语境;“I don’t like apples, and my brother doesn’t like them too.”中“too”用于肯定句末,此处错误;“I don’t like apples, and my brother also doesn’t like them.”中“also”用于肯定句中,位置也不对,所以错误 。
9. 答案:B
解析:“This cake is for my dad.”中“for”表示“给,为了”,“这个蛋糕是给爸爸的”符合语境;“This cake is to my dad.”表述错误;“This cake for my dad.”缺少谓语动词,句子不完整 。
10. 答案:A
解析:“I want my sister to help me draw.”中“want sb. to do sth.”是固定搭配,意为“想要某人做某事”,表示“我想让姐姐帮我画画”,符合语法和语境;“I want my sister help me draw.”中“want”后缺少“to”;“I want my sister helping me draw.”不符合“want”的用法规则 。
五、连词成句
1. 答案:I can dance for you.
解析:“I”是主语,“can”是情态动词,后接动词原形“dance”,“for you”表示“为你”,按照“主语 + 情态动词 + 动词原形 + 其他”的结构组合成句。
2. 答案:I want to buy a toy fox for my brother.
解析:“I”是主语,“want to do sth.”表示“想要做某事”,“buy sth. for sb.”表示“为某人买某物”,“a toy fox”表示“一只玩具狐狸”,按照这个逻辑顺序排列单词成句。
3. 答案:Please look at your new picture.
解析:“Please”表示请求,放在句首,“look at”是固定短语,后接宾语“your new picture”,组成祈使句。
4. 答案:She can also sing well.
解析:“She”是主语,“can”是情态动词,“also”用于肯定句中,放在情态动词之后,“sing”是动词原形,“well”是副词修饰“sing”,按照这个顺序排列单词。
5. 答案:What do you want to do for your family?
解析:这是一个特殊疑问句,“What”是疑问词,放在句首,“do”是助动词,“you”是主语,“want to do sth.”表示“想要做某事”,“for your family”表示“为你的家人”,按照特殊疑问句的结构组合单词。
