[揽瓜阁逻辑小分队] day58
Day 58
1. 老师PK电脑网络
现在科技越来越发达,电脑的使用率极高,并且电脑知识量大。所以人们认为网上上课,或者使用电脑自学,可以代替传统的老师授课方式。However, the teachers will be replaced by the computers soon.
问:think little
人们还是需要老师。网上的信息量太大,学生无法甄别哪些正确错误,或者没发按照规定,完成应该掌握的部分。有时候学生有疑问,老师能够更好的给出解答。
填空(考古V1):
因为没有supervised by teacher,学生也不知道学什么
2. 神奇洗衣酶
洗衣粉经常会改变衣服上的一些纤维fiber的特点,表现出来就是掉色。一个公司打算往洗衣粉里加一种酶,这个酶可以清除已经变性的fiber,从而防掉色。
问:加强
这个酶不会和洗衣粉里的其他物质发生反应而影响其活性
正确答案也是排除不良副作用。
þ 那些没有变性的fiber,可以保护自己不受这种酶的digest(考古)
þ 这些酶不会破坏去垢的功效(原始)
3. 吃货大象
The expansion of largescale farming in Africa and Asia has destroyed much of the natural vegetation on which elephants have historically depended, forcing them to turn to cultivated land to satisfy their enormous appetites. As a result, farmers have lost millions of dollars worth of crops annually. Yet even if elephant sanctuaries were created on a widespread basis to guarantee elephants sufficient natural vegetation, the raiding would likely persist, since____
(A) when elephants forage for food, they typically travel in herds.
(B) foraging elephants have been known to cause substantial damage even to plants that they do not eat.
(C) some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.
(D) elephants tend to prefer cultivated crops to wild vegetation as a food source.
(E) elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.
