Language points
1. Let’s call Wonders of the World and join in the discussion.
join in的意思是“参加某种活动，加入到”。
辨析：join，join in， take part in
1)join指加入某个党派，团体组织等，成为其成员之一，意为 “参军、入团、入党等”。和某人一起做某事，其结构为：join sb. in (doing) sth.，根据上下文，in (doing) sth. 也可以省去。
2) join in多指参加小规模的活动如“球赛、游戏”等，常用于日常口语。
3) take part in 指参加会议或群众性活动等，着重说明句子主语参加该项活动并在活动中发挥作用。
如：We’ll _____________the English evening tonight.
When did your brother _____________the army?
Will you _______________ us in the discussion?
2. I think natural wonders are more interesting than man-made ones.
1) I think 为主句，后面是省略了连接词that的宾语从句。如：I think maths is more difficult than English.
2) ones 作代词，指代wonders。 ones 指代复数名词，同类不同物。
3. Hmm, I’ve never seen it, so I’m not sure I agree with you.
1) be sure that/ be sure of 确信... ，对...有把握。
2) agree with表示“同意某人的意见、想法、解释”等（对象是人或人的观点）; agree to表示 “同意/赞成……”，后面跟表示计划、建议、安排等的名词、代词，或接动词原形。
