人教必修二UNIT 3核心考点专讲专练【考点剖析】arise vi. (arose, arisen)出现;发生;起身;起床;上升[温馨提示]arise为不及物动词,没有被动语态。

arise 作“发生;出现〞讲时,主语多为抽象名词,如argument,problem,quarrel,question等。

【易混辨析】arise, arouse,rise与raise原形过去式过去分词现在分词含义arise (vi.) arose arisen arising在现代英语中主要用于借喻,指“出现;发生;产生〞。

arouse(vt.)aroused aroused arousing 指“唤醒;激起〞,后常跟抽象名词。

rise (vi.) rose risen rising使用范围较广,指“升起;上升;增长〞,也可指“起立;起床;地位升高〞等。

在操作员的教练下，它们甚至还可以控制火箭探索月球，指导具有人类性格的机器人擦洗地板和照顾你调皮的侄女。

不管怎么说，电脑都是如此的有用，以致的确给人们带来了快乐。

然而，电脑很容易受到病毒的攻击，这一现实已经成为一个难以处理的难题，结果，电脑在某种程度上是很危险的。

因此，就个人而言，我很担心电脑在某些领域，例如金融方面的广泛应用。
