新概念3英语高级词汇问题，如果解答对自己英语很有帮助！

Lesson 58
10 -and advised her not to stay _________ in the flat^
a)single b)on her own c)lonely d)selfish
原文是The inspector then asked the old lady to try to chek what was missing by the next day and advised her not to stay alone in the flat for a few nights.
导读答案是b,但a）single为什么不行，single不是有单身的含义么

Lesson 56
12________we think it a miracle that they were able to do so.
a)To this day b)Up till now c)As yet d)Even so
原文：We still think it a miracle that they were able to do so.
still依然至今，b)不就是么，为何导读选a）啊，a)和b)有什么区别？

Lessons 54
12I had been completely defeated by the __________
a)speedy swarms b)hungry hordes c)inventive creatures d)ingenuous insects
原文是I realized sadly that I had been completely defeated by their ingenuity.导读答案是c)但d)为什么不对，我不清楚……

Lesson 51
10Bagrit foresaw that computers would become _______ small to hold in the hand.
a)adequately b)sufficiently c)capably d)possibly
原文……foresaw a time when computers would small enough to hold in the hand.我记得enough,adequate,sufficient是近义词，都表示"足够"，为何导读答案选b)不选a)啊

以上问题可能有点naive 望高手请教 谢谢……

Answer 1

single 名词:独身者,独身主义者
形容词:单独身主义的,个别,一,单个,单身,只,单一,独,独身,更多

to this day 迄今 之后多用一般时
up till now 到现在为止 之后多用完成时

从句意（……我被他们的聪明才智打败了）上说他们是聪明的生物，而不是直接用坦率的昆虫更好吧

enough sufficient adequate
意思都含“充分的”、“足够的”。 但是三者区别较大：
1.enough 系常用词, 常可与 sufficient 互换, 它除表示“足以满足需要的”外, 还含有“数量很多使人感到心满意足的”的意思, 如:
We have enough money to spend.
我们有足够的钱花。
2.sufficient 用于正式文体中, 指“分量或数量足以满足需要的”, 如:
The food is sufficient for a week.
食物足够一周用。
3.adequate 指“足够符合特定(有时可指最低)的资格、分量、才能等”着重“符合一个客观要求或标准的”, 如:
To be healthy one must have an adequate diet.
一个人想要健康, 必须有足够的规定饮食。

注意:enough 还可以做副词,来修饰形容词,但必须放在形容词的后面

例: She is not old enough to go to school
她没有达到上学的年龄.

Answer 2

1.single表示单身，与已婚对应；这里的意思是不要一个人住。
2题前面一个回答得蛮好。
3，我支持选d
4,几个词都表示足够，但是enough 通常后加形容词然后跟动词不定式，这就是该题的重点。这几个词的区别百度知道上有。

Answer 3

第1题 空里需要的是副词 single是形容词 lonely就是形容词 所以不能选 而alone有副词词性

第2题 up till now后常用现在完成时或现在完成进行时 两个此后面跟的时态不一样

第3题 从语法上来说都对 应该是翻译的问题了 联系上下文吧

第4题 adequately意思是“足够地，能够地，足以......”，在这里就表示程度了 sufficiently意思是“充分地，充足地”，但是表示的是数量，不是程度，
