　　高二英语Unit18 Inventions知识点总复习教案

　　Section I 课前准备、听力、口语

　　1. Never throw away or wash chopsticks again. 千万不要扔掉再洗这些筷子。(p.57 A)

　　▲ throw (threw，thrown)

　　(1) 投，抛，扔 He threw the ball 20 metres. 他把球投出20米。

　　(2) 摔倒...... The policeman threw the thief to the ground.警察把小偷摔倒在地面上。

　　(3) 发射，射 China has throw a satellite into space recent- ly. 中国最近向太空发射了一枚卫星。

　　辨析：throw...to sb. 与throw ... at sb.

　　throw sth. to sb. 指"把某物扔向某人"，其目的在于"传递" (for sb. to catch) 介词to纯粹表示行为的方向，其动机是善意的；throw sth. at sb. 指"把某物打向某人"，其目的在于"打" ( = try to hit sb.)。介词at表示动作在于企图攻击的目标，其动机是恶意的。如：He threw the ball at me. (= try to hit me) 他扔球打我。He threw the ball to me. (= for me to catch) 他把球传给了我(= He threw me the ball.)

　　辨析：throw与cast

　　throw是普通用词，使用频率高，它指用力抛掷这一行为。cast比throw正式，指迅速扔出一重量较轻的物体。经常用作比喻或无意识行为，在某些成语及特殊用语中须用cast，如cast a net "撒网"；cast a vote"投票"；cast anchor"抛锚"等等。如：Will you move, please? You're casting (throwing) a shadow on my book. 你走开点好吗?你的影子正好投射在我的书上。He quickly threw the ball into the basket. 他迅速地将球投入篮里。The dice is cast. 事已定局。

　　拓展：throw oneself into 积极从事; throw away 扔掉; throw about 乱丢；乱扔(东西); throw back 扔回; throw...at... 朝......扔，向......砸去; throw off 匆匆脱掉

　　▲ save (1) vt. 救、挽救 The brave soldier saved a child from a burning house. 那勇敢的战士从着火的房子里救出了一个孩子。Only socialism can save China. 只有社会主义才能救中国。

　　辨析：save与rescue: save与rescue两者都有"营救"之意；但save侧重于"保全"之意，而rescue则侧重于"从囚禁中救出"之意。如：In order to save the country, many gentlemen laid down their lives. 许多志士仁人为国捐躯了。They rescued him from prison. 他们营救他出狱。

　　(2)节省；储蓄 Don't spend all your money, save some of it for future use. 别把钱全部花光，储蓄一点儿以备将来之用。

　　(3) n."烦恼"不可数；"使人发愁的事(人)；烦心的事"(可数)，且常用复数。This worry is enough to drive one mad. 这烦恼足以令人发狂。He has many worries. 他有很多的烦恼的事情。

　　辨析: worry与trouble: trouble的含义宽广，事无巨细都可用它，且含有一定的惊慌意味；worry"担心""发愁"，它指没有根据的，经常是不必要的忧虑不安的心情。如：

　　Uneasiness troubled her heart. 她感到心神不定。I'm troubled by the doctor's report. 医生的诊断结果令我焦急。Don't worry，tomorrow will be better. 别担心，明天会更好。We're all worried about you. 我们都在为你担心。
