Task9用2a和2b中的信息，完成2c。小组展示。

二、知识点：

1.现在完成时表示从过去一直持续到现在的动作或状态，并可能还将持续下去。简称“延续用法”

1）常与for, since引导的时间段的时间状语连用.

2）动词使用延续性动词。因为瞬间动词在肯定句、疑问句中不能和时间段连用.

since: (自…以来)

1)since+时间点    He has stayed here since 5 o’clock.

2)since+ 时间段+ ago   He has stayed here since 5 hours ago

在现在完成时态中，for与since引导的时间状语可以相互转换。

since＋一段时间＋ago＝for＋时间段;

since two weeks ago=for two weeks;

2.---How long have you had that bike over there? 

   ---I’ve had it for three years!I learned how to ride a bike on it.

    long可与疑问副词how构成how long短语,意为“时间多久或物体多长”，是对表示过去已经开始持续到现在的动作或状态，常用的时间状语since+过去点的时间，for+一段时间（数词+量词）。

如:How long does it take him to get to his hometown?他回自己的家乡要多长时间？

---How long has your brother been a soldier? 你兄弟当了多长时间的兵了?

---He has been a soldier for one year.他成为一个士兵已经一年了。

3. Amy wants to keep her old things because they bring back sweet memories.

memory 在此处作可数名词，其复数形式为 memories。

What is your earliest memory?

【拓展延伸】① memory 作名词，还可意为“记忆力”。

I have a bad memory.

② memorize 作动词，意为“记忆”。

My Chinese teacher asked me to memorize the poem.

in need 意为“贫困；在困境中”，为固定短语。

in need of 意为“需要……”。

We are collecting money for children in need.

A friend in need is a friend indeed.(谚语)患难见真情。

After working for twelve hours, she was in great need of a rest.
