Hi, Mary, this is Li Jun. I’m not very good at English. Can you help me I’m not very good at English. 我英语学得不是很好。 be good at是擅长的意思，be not very good at则翻译成不是那么优秀。一般后面可以直接跟名词或者 doing sth. Sure. You are so nice. Are you free tomorrow Oh, sorry. I’m going to see Sam tomorrow. He’s ill at home. Can I go with you I’m going to see Sam tomorrow. 我明天去探望Sam. be going to do sth. 与 will 代表意思相同，都是用于一般将来时中。 Of course. And we can study English on Sunday. Great! Then see you tomorrow. See you. Why does the author describe Mary as a kind girl Friday evening 周五下午 call up 给…打电话 be good at 擅长于 be ill 生病了 Just then, Li Jun calls up. 就在这时，Li Jun打电话过来。 I’m not very good at English. 我英语学得不是很好。 I’m going to see Sam tomorrow. 我明天去探望Sam. He’s ill at home. 他生病在家。 https://www.21cnjy.com/help/help_extract.php
