Who are they?);2. “who's”是who is的缩写,注意其答语需用完整的人称代词+be动词(如Who's he? He's my uncle.) 日常交往类 thank you for... help sb with sth play with sb look after 1. “thank you for + 名词/动名词” 表示“因……感谢你”(如Thank you for your help. / Thank you for helping me.);2. “help sb with sth” = “help sb (to) do sth”(如Help me with my English. = Help me (to) learn English.);3. look after = take care of,均表示“照顾;照料” 其他常用类 be from / come from in the photo on the desk too / also 1. be from与come from均表示“来自”,否定句:be not from / don't/doesn't come from(如He is not from China. = He doesn't come from China.);2. 方位介词in表示“在……里面”,on表示“在……上面”;3. too用于句末,前加逗号;also用于句中,be动词/情态动词后、实义动词前(如I like apples, too. / I also like apples.) 二、分层练习(基础→提升→拓展) (一)基础题:短语翻译(中英互译,夯实记忆) 1. 我的全家福 ________________ 2. 这些是我的堂兄弟 ________________ 3. 很高兴见到你 ________________ 4. 来自美国 ________________ 5. 帮我学数学 ________________ 6. 照顾我的小妹妹 ________________ 7. who's that girl ________________ 8. thank you for your present ________________ 9. play with my friends after school ________________ 10. two photos of my family ________________ (二)提升题:短语填空(用所给短语的适当形式填空,每词限用一次) be from, this is, look after, thank you for, play with, who is, come from, help... with, too, nice to meet you 1. — ________ my aunt, Linda. — ________!
