1、能够掌握语法：由before、after、when、while、since、

till、until、as soon as和whenever引导的时间状语从句。

2、能恰当运用时间状语从句进行口头和书面表达。

教学重点、难点

1.学习新词汇：career, against等。

2.掌握新句型：

 It’s the first time we have played basketball since this Monday.

   The best moment in his career was in 2004—he scored 41 points in a game against the Atlantic Hawks.

3. 能熟练运用时间状语从句进行表达。

二、词汇、短语 （包括词的各类变形，构词，归类等）

三、句型（语法）

1. using the conjunctions “ before”, “after”, “when”, “while” to introduce time clauses. They can be placed at the beginning or in the middle of sentences.

Before means earlier than a certain time.

After means later than a certain time.

When means at or during a certain time.

While means during a certain time.

2. using “since”, “till”, “until” to introduce time clauses.

Since means from a certain time . the verb in the main clause is often used in the present perfect tense.

Till and until both mean up to a certain time, but till is more informal than until.

When we use verbs like go, leave, arrive, etc. in the main clauses, we should use the structure not…till/until.

3. as soon as and whenever can also introduce time clauses.

As soon as means when something happens, or a short time after something has happened.

Whenever means at any time.
