判断:数轴可以表示任意有理数.书后答案是错,我认为是正确的, 具体解释一下在语言学中Synchronic和Diachronic的概念 deixis在语言学里是什么意思 发电机的换向器是什么!是套节器吗 The students-----busy-----(get) ready for their exam now. 有换向器的发电机,是不是就叫直流发电机呢?直流发电机接直流电源会转动,那交流电动机接交流电源是不是也会转呢? 2.All of you are very busy ---[get] ready for this exam,arenot you? 发电机带换向器的,是什么电 如果没有电刷和换向器,电动机会怎么样?发电机又会怎么样? 向外部供给直流电的发电机需要用换向器吗? 英语语言学指的是什么? 口语中,are you ready?可以直接用ready回答吗? 自负什么意思啊?长这么大了,一直不会准确的用这个词.谁能结合一个事实帮解释一下.谢了 各类的词语,写出表示快的词语1.看书快_______2.吃饭快__________3.走路快_________4.回答快_______5.变化快________6.时间快 人外有人 天外有天的意思总有超过你的人. 人外有人, 人外有人,天外有天, My uncle is very busy.He has no time ____ his friends 人外有人天外有天的意思 Father__(mean)to call on a close friend,but he was very busy 天外有天人外有人这句话是什么意思? 关于光或力的现象和解释只要贡献一个就行! 怎么理解英语语言学的二层性 时间和空间的概念都超出了人类思考的极限吗? 人类的发展空间?是智力和大小. we have science on Tuesday and Thursday对 on Tuesday and Thursday提问 We have science on Tuesday and Thursday.(对画线部分提问) 画线部分为:on Tuesday and ThursdayThis subject is interesting.(改为同义句)This____ _____ ____ subject单句改错We go to the school at 7:30 in the morning.Amy can pl (Mr Wang)is his favorite teacher.(对括号部分提问) We have science (on Tuesday and Thursday ).(对括号部分提问) They get up at seven in the morning.(改为否定句).Does he like to play with his cat?(做否定回答) She likes They have Science lessons (on Monday and Wednesday.)对括号内部分提问 They have maths on Tuesday and Friday.对on Tuesday and Friday提问 能人背后有能人是什么意思? 英语翻译“浅谈《平凡的世界》中的人物奋斗观”请把我的论文题目翻译成地道一些的英文!那个我也会!呵呵
