wonder 表示“(对某事)感到疑惑;想要知道;想弄明白;琢磨”，后面常接由what，how，who 或者if/whether引导的宾语从句。
e.g. ①wonder how they’re getting on. 我想知道他们现在过得怎样。

encourage sb. to do sth. 鼓励某人做某事。

Step 6 GrammarFocus
Ask students to read the sentences of Grammar focus aloud.Then let them learn the Present Perfect Tense(和学生一起总结出现在完成时的用法)
1. 用法
肯定式 | 否定式 |
I/You/We/They have finished the work. He/She/It has finished the work. | I/You/We/They have not finished the work. He/She/It has not finished the work. |
疑问式 | 回答 |
Have I/you finished the work? Has he/she finished the work? | Yes，you/I have. No，you/I haven’t. Yes，he/she has. No，he/she hasn’t. |
2. 构成：
have(助动词) + p.p
has(第三人称单数助动词) + p.p
have not 常缩略为haven’t；has not 常缩略为hasn’t。
3. have been to & have gone to区别
比较：He has been to Beijing.
他曾去过北京。（人已回来，可能在这儿）
He has gone to Beijing.
他已经去北京了。（人已走，不在这儿了）。
have / has been (to) 表示“曾经到过某地”，说话时此人不在那里，已经回来。侧重指经历。
have / has gone (to) 表示某人“已经去某地了”，说话时此人可能在路上或已到那里，不在这里。
4. 一般过去时与现在完成时的区别
比较：I have seen the film..
我看过这部电影。（我了解这部电影的内容）
I saw the film last month.
我上个月看了这部电影。(只说明上个月看了这部电影，不涉及现在情况）
① 一般过去时只强调过去的动作；现在完成时强调过去的事情对现在的影响。
② 一般过去时通常与表示过去的时间状语连用；现在完成时则不能与表示过去的时间状语连用。
③ 一般过去时单纯表示过去的经历；现在完成时表示过去的动作或状态延续到现在并可能持续下去。
一般过去时的时间状语有：yesterday，last week，…ago，in1980，in October，just now…
现在完成时的时间状语有：for，since，ever，never，just，already，yet，in past years， …
共同的时间状语有：this morning，tonight，this summer，before，already， …
Then let the students read the above aloud.
