重点句子点拨:
1. Do you think there will be robots in people's homes? 你认为在人们的家里将来会有机器人吗?
Do you think...? 结构通常用来征求对方的意见或看法,后面接宾语从句,从句用陈述语序。本句的肯定回答用"Yes, there will.",否定回答用"No, there won't."。
例句:---Do you think there will be robots in school? 你认为学校将来会有机器人吗?
---Yes, there will. 是的,会有。
拓展: do you think还可以用作插入语,在特殊疑问句中放在特殊疑问词之后,疑问句其他部分用陈述语序。
2. I think every home will have a robot.我认为每个家庭都将有一个机器人。
点拨:"will+动词原形"构成一般将来时。
(1)一般将来时表示将来某个时间要发生的动作或存在的状态,也表示将来经常反复发生的动作,常与表示将来的时间状语连用。如tomorrow, next year," in+时间段"等。一般将来时由"助动词will+动词原形"构成,第一人称还可以用shall。
例句: I will\shall go to the park tomorrow.我明天要去公园。
(2)will和be going to 都可以表示将来,但有区别。will表示单纯的将来概念,而be going to强调事先经过考虑、安排而计划或打算要做某事,或者概括某种迹象判断某事有可能发生。
(3)一般将来时的否定构成: 在will\shall 后面加not。will not可缩写为won't。
(4)变为一般疑问句:将will\shall提到主语前面。其肯定回答为"Yes,主语+will.",否定回答为"No,主语+won't."。
3. Will people use money in 100 years? 一百年后人们还会用钱吗?
辨析:in, after与later
in和after都可以表示"在……之后",但用法有所不同。 in是指以现在时间为起点的"在一段时间以后",也可以表示"在将来多少时间之内",句中的谓语动词要用一般将来时态。
例句: He will be back in two days.他将在两天后回来。
After常常指以过去时间为起点的"在一段时间之后",所以它常与过去时态连用。当after指某个特定的未来时刻或日期之后或指以将来某一时间为起点的若干时间之后时,它可以与将来时态连用。
例句:He started on Sunday and arrived in Beijing after three days.他星期天动身,3天后到达北京。
I'll be free after Friday.我星期五之后有空。
He will be back after three o'clock.他3点之后回来。
later 是副词,表示"一段时间之后",构成"一段时间+later"短语,用于过去时;如果单独使用,可与将来时或过去时连用。
例句: Nine months later they were discovered.九个月之后,他们被发现了。
4. There will be less free time.将会有更少的闲暇时间。
There will be fewer people.将会有更少的人。
There will be more pollution.将会有更多的污染。
辨析:fewer与less
Fewer与less分别为few和little的比较级,都意为"更少的"。Fewer与可数名词复数形式连用,其反义词为many的比较级more。
less与不可数名词连用,其反义词为much的比较级more。
例句:They buy fewer cigarettes and less beer now.现在他们买的香烟和啤酒少些了。
拓展:
less也可作副词,意为"较少地,更少地",常用来修饰形容词、副词或动词。其反义词为more,用法与less相同。
例句Eat less, drink less and sleep more.少吃,少喝,多睡觉。
注意:
few, little含有否定意味,意味"几乎没有" a few, a little含有肯定意味,意味"一点,一些"。
