高一必修1 Unit2學案及答案(集體備課)
i. 要點探究
1. can you find the following command and request from reading?你能從“閱讀”中找到下列命令和要求嗎？
（1） command n&vt 命令；指令；手掌
fire when i give the command.我一下命令就開火。
the troop was under his command.那只部隊由他指揮。
he has a good command of english.他精通英語。
the teacher commanded him to go out the the classroom.=（the teacher commanded that he should go out of the classroom.）老師命令他離開教室。
思維拓展：
under one’s command 由某人指揮
give a command 下命令
carry out a command 執行命令
have a good command …精通
command sb. to do命令某人做
注意：command 后面的表語從句或同位語從句中謂語動詞用“(should )、動詞原形”
(2)request n&vt 請求；要求
finally they had to make a request for help.最后 他們只好請求幫助。
he went there by request /at their request.他應邀前衛往。
visitors are requested not to smoke here.參觀者請勿在此吸煙。
they requested that help(should ) be sent at once.他們請求立即施以援助。
思維拓展：
make a request for sth請求得到某物
at one’s request 應某人的請求
be request應請求；應邀
request sth.(of /from sb.)（向某人）請求得到某物
request sb to do sth.請求某人做某事
注意：request 后面跟從句時，從句中的謂語用“should+動詞原形”結構，should 可以省略。
ii. 語法突破 直接引語和間接引語(ii)
1. 當祈使句作直接引語表示要求和命令時，變間接引語時常采用 tell/order/command sb.to sth.的形式。
“hurry up,”he said. he told me to hurry up.
he said to them,“don’t go out.” he ordered them not to go out.
注意：若直接引語中祈使句是否定形式, 變間接引語時,不定式符號to 前要加 not或never。
2.當祈使句作直接變間接引語表示請求時，變間接引語時常采用request/beg/ ask sb. to do sth.的形式。祈使句中的please 在間接引語中必須省去。
