1.practice the guitar 练习吉他(教材P22 1b)

practice v.＆ n.练习

(1) practice 在此处作动词，其后可以接名词、代词或动词-ing形式作宾语。

You need to practice English every day. 你需要每天练习英语。

These foreigners are practicing speaking Chinese. 这些外国人正在练习说汉语。

(2) practice还可作名词，意为“练习”。

Practice makes perfect. 熟能生巧。

Learning English needs practice. 学习英语需要练习。

2.do the dishes 清洗餐具 (教材P22 1b)

dish n.碟；盘

dish作可数名词，常用the dishes表示“（待清洗的）餐具”。do the dishes清洗餐具,相当于wash the dishes。dish还有“菜肴；一道菜”之意。

The glass dish is beautiful. 那个玻璃盘很漂亮。

We must do the dishes before we go out. 我们外出前必须清洗餐具。

This is an excellent hot main dish. 这是一道绝好的热主菜。

3.on school nights 上学期间夜晚(教材P22 1b)

 night，尤其是指深夜, 也就是晚上10点至午夜这段时间。

night是抽象名词, 故其前通常不加the, 但特指时则要加the。其复数nights可用作状语, 意思是“每夜”, 它的反义词是day。

【拓展延伸】区别at night, in the night, on the/a night

1)at night 是固定搭配,表示泛指的 “在夜晚”, 此时night 前不加冠词, 也没有其它修饰语, 后面也不接短语或其它成份。

       He often stays up at night. 他晚上经常熬夜.

       We can see the stars at night.夜晚我们可以看见星群。

2)in the night 表示某个夜晚,不具体,night 前用定冠词the, 不用其它的修饰词。侧重于表示一个时间段,相当于during the night. 

     Jack calls me three times in the night.杰克在夜里给我打了三次电话。

3) on the/a night表示某一具体日期的夜晚,其后常跟 of +具体日子或在night前用其它限定词来修饰。

The story happened on a cold winter night.

Can I watch TV on school nights? 

4.  before dinner 晚饭前 (教材P22 1c)

 before 在此处为介词，意为“在……以前”，表示时间，反义词为 after(在……以后)。

You must go to bed before 10 o’clock. 你必须在10点前上床睡觉。

【拓展延伸】(1) before作介词，还可表示“在……的前面”，表示位置，其反义词为behind。

There is a desk before me and a chair behind me. 我的前面有一张课桌，后面有一把椅子。

(2) before还可作连词，意为“在……以前”，后接句子。

Do it before you forget. 尽早动手，免得忘了。
