引导的时间状语从句中可以根据句意的需要用一般现在时、一般过去时、过去进行时,分别说明现在、过去、甚至将来的行为。‎ ‎②family为集合名词(也叫集体名词)。当它指家庭成员时,单数形式表示有许多成员,就像people一样,谓语动词用复数形式(即:后面的动词是复数概念,系动词be 用 are, 其它动词不变为第三人称单数),意思是“……一家人”。例如:The family often go abroad during summer.这家人常常去国外避暑。His family are waiting for him.他的家人正在等他。(family为家庭成员)。但是,当它指整体概念(即:将这个家庭作为一个整体)时,谓语动词用单数形式,意思是“……家庭”。例如:My family was very poor.我家很穷。This family is the poorest one in the whole village.这个家庭是整个村子里最穷的一家。This family is taken as an evil one.这个家庭被视为邪恶之家。(family为一个整体)【辨析比较】The Green family are watching TV now.格林一家现在正在看电视。The Green family is a big family.格林家是个大家庭。‎ ‎③mice是mouse的复数形式,意为“老鼠”,是不规则的名词复数变化,a family of mice一窝老鼠。例如:There is a mouse in the house.房屋里有一只小老鼠。Five mice,six mice,seven mice,more mice.五只老鼠,六只老鼠,七只老鼠,更多老鼠。There were three mice in the kitchen.厨房里有三只老鼠。‎ ‎15.Father mouse shouted at the cat,“Woof,woof!” The cat quickly ran away.老鼠爸爸冲着猫大声吼叫“汪汪,汪汪!”猫迅速地跑开了。‎ ‎【重点注释】①shout动词,意为“呼叫;喊叫”。shout at sb.意为“冲/对某人大声叫嚷;大声吼某人”(带有恶意或不礼貌的喊叫),多指因生气或愤怒冲某人大声吼叫或嚷嚷。shout to sb.意为“呼喊(喊叫)某人”(普通的喊叫)。例如:“Help!”he shouted.“救命!”他呼喊。He shouted for help.他大声喊救命。Don’t shout at the children,please.请别冲着孩子们大声嚷嚷。“Sit down here! ”she shouted to John.“坐这儿!”她向约翰大声喊叫。‎ ‎【辨析记忆】shout at与shout to的区别和用法:请看下面两个句子:(1) He shouted at me to get out of his way.(2) He shouted to me to come over to help.要正确理解这两句子,关键是要理解shout at与shout to的意思和区别。shout at sb与shout to sb ‎ 的区别可大致描述为:前者多指因为生气等而非善意地对某人吼叫,后者多指因距离远而不得不大声叫喊(否则对方无法听见),不带生气等感情因素。所以上面第(1)句的意思是:他对我怒喊不要挡他的路。第(2)句的意思是:他大声叫我过去帮忙。【注意】类似用法比较(尤其注意其中at与to的区别):The dog came at the boy. 狗向小男孩扑来。(意即咬人) The dog came to the boy. 狗向小男孩走过来。(无咬人之意) All of them ran at me. 他们都向我扑来。(意即攻击我) All of them ran to me. 他们都向我跑过来。(无攻击之意) He threw the ball at me. 他把球向我砸来。(意欲打我) He threw the ball to me. 他把球抛给我。(无打人之意) He shouted at his wife. 他对他妻子吼叫。( 意在训人) He shouted to his wife. 他朝他妻子大声喊叫。(无训人之意) ‎ ‎②woof[wu:f] n.是一个象声词,表示狗的叫声。moo [mu:]n.牛叫声。mew[mju:]n. 猫(通常指小猫)或海鸟的叫声。‎ ‎③away副词,意为“离开;远离”,run away跑开/跑掉/逃跑,go away走开/离开,be away from sw.=leave sw.离开某地,be far away from sw.离某地很遥远。例如:The little girl is so shy that she runs away when I want to talk to her. 这个小女孩太害羞了,我刚想和她说话,她就跑开(掉)了。Go away!I don’t want to see you again.走开!我再也不想看到你了。‎ ‎【辨析记忆】be away from是leave 的延续性动词,leave 是瞬间动词(短暂性动词)。用在表示延续性时间“for +一段时间”中,要把leave 变成be away,离开某地就代表不在某地了。leave sw.要表示离开某地多久就要变be away from sw +for +一段时间。例如:She has been away from Beijing for 2 years.她离开北京两年了。= She left Beijing 2 years ago.她两年前离开的北京。‎ ‎【比较记忆】My home is far from my school. 我家离学校远。My home is far away from my school. 我家离学校很遥远。My home is 5 miles away from my school. 我家离学校有5英里远。‎ ‎16.…that’s why it’s important to leave a second language… ……那就是学好一门外语很重要的原因……‎ ‎【重点注释】①That’s why…意为“那就是为什么……;那就是……的原因”,why引导表语从句。例如:That’s why he didn’t come.那就是他没有来的原因。‎ ‎②a second
