新概念青少版2B Unit21教案

Unit 21 The weather forecast目标：一：将来时、现在时和过去式的灵活切换和使用。

二：和天气有关的语言点。

三：写一篇关于天气预报的文章一：语言点汇总：1.let's go over to sb 让我们转到---let’s do sth 表达建议，是所有人一起去做而let us do sth 是一种请求，请求别人允许我们做某事。

而over和go, come 等连用时表达了“越过”的含义，go over to =move across to be over= be at an end, be finished。

表达转回来则用：let’s go back to sb. 通常就简略为‘’’back to sb’.2.两个前缀fore和for fore 的意思是“和未来有关”，而for 则是’’无’’的意思，如forecaster，forget3.rain ---不可数名词表泛指，不加冠词，如特指一场大雨，则是a heavy rain.类似的用法如：snow, fog,wind 等。

4.表示时间：in the day，at night ，in the evening，at noon，at dawn(在黎明)，atdusk（在黄昏），at twilight （在黄昏），in the morning ，in the next few days, next weekend,a short time ago, in two years’ time5.at the London Weather Centre 介词at 表示小的具体的地点。

6.和天气变化相关的词：change, blow, bring sth in , come in , have some rain showers,Temperatures will rise to 12 degrees Celsius. , Night temperatures will fall to 4 degreesCelsius., --- the outlook for next weekend, weather forecast, forecaster, it will feelcold/warm/hot.7.分清及物或不及物不及物：come in, rain , fly, rise , fall , blow , go to the theatre, look for a job, fly to Paris 及物：bring in, have a holiday , tell a joke, buy new clothes, have some rain, move house,二：时态灵活使用：请翻译：1.去年他们搬家去了上海，现在住在上海。

Junior New Concept English 2BUnit 16 The Weather ForecastLesson 411.the weather forecast = the weather report weather forecaster 天气预报员询问天气句型：What’s the weather like today? 或How is the weather today? 今天天气怎么样？(What will the weather be like tomorrow? 明天天气怎么样？)It’s sunny(晴朗的) \windy(刮风的) \cloudy(多云的) \snowy(下雪的) \rainy(下雨的) \foggy(多雾的) \ dry（干燥的）\wet（湿的）….2.And now it’s five to nine, and time for the weather forecast.It’s time for sth. It’s time to do sth. It’s time for sb. to do sth.这三个句型都可表示“是做某事的时候了”，但用法有所不同。

例：①It’s time to do sth.意为“是做某事的时候了”，但没有讲清楚是谁去做。

It’s time to go to school. 是上学的时候了。

②It’s time for sb. to do sth.意为“是某人做某事的时候了”，for后面通常接一个表示人的词语，其后的不定式所表示的动作就是这个表示人的词语sb.发出的。

例：It’s time for you to go to school. 是你上学的时候了。

③It’s time for sth.也表示“是做某事的时候了”，但这个句型中介词for的后面只能是表示物的名词，说明所要做的事情。

例：It’s time for class. 是上课的时候了It’s time for school. 该上学了。
