If it is not powerful enough, you will find the answer on page 67. 如果它还不够强大，你可以在第67页上找到答案。(1) enough可以作名词或代词，意为“足够；充分”。作代词时，它可以代替可数名词或不可数名词，在句中作主语或宾语。Eg: Enough has been said on this subject. 关于这一主题，说得已经够多的了。(2) enough可作形容词，意为“足够的；充分的”。Eg: I hope there are enough glasses for the party. 我希望辈子的数量够聚会使用了。(3) enough作副词时，意为“十分；充分地；足够地；充足地”，置于被修饰的形容词或副词之后，长于介词for或不定式连用，在句子中作状语，表示程度。Eg: Mum, I think Im well enough for school. 妈妈，我觉得我身体好了，可以上学了。2. Abacuses are so fast and accurate that people still use them today. 算盘计算快且精确，以至于人们至今仍然在使用它们。so that作“如此以至于”解，连接一个表示结果的状语从句，一般用法是：so + 形容词或副词+ that引导的从句。Eg: Doctor Wang is so good that everybody respects and loves him. 王医生是如此好的一位医生，以至于大家都尊敬并爱戴他。3. This was a very important invention because it made it easier to write big numbers and to calculate. 这是一个非常伟大的发明，因为它使得人们书写大的数字和计算更为容易。“make something + 形容词”的结构用以表示“使什么怎么样”的意思。Eg: Heaters and air conditioners make us more comfortable in winter and summer. 取暖器和空调使我们在冬天和夏天过得更舒适。4 Shakuntalas brain took fifty seconds to find the answer, like lightning. 夏昆塔拉的大脑的运算速度就像闪电一般，仅花了50秒就得出了答案。 take意为“花费”，后面通常跟时间。take表示“花费多少时间”时，主要有以下两种用法：(1) 事物 + take(s) + 时间 + (动词不定式)Eg: The bus takes about half an hour to get there. 坐公共汽车去那儿要半小时。(2) It + takes + (某人) + 时间 + 动词不定式Eg: It takes my father about an hour to go to his office by underground. 我爸爸乘地铁去办公室大约要一个小时。5.Everyone knows at least two his or her own language and the international language of numbers. 每个人至少懂两种语言-他或她的母语以及“数字”这一国际语言。at least 意为“至少；无论如何；不管怎样”。反义词at most “至多；最多”Eg: He has waited for you at least 30 minutes. 他至少等了你30分钟。Focused Practice (1B) 第四课同步语法+词性转换一、 同步语法 Keys: BCAAA CDCAD Keys: DDBDA BBCDA二、词性转换 Keys: 1. ways 2 calculate 3. fifty 4. five 5. equals 6. turn on Keys: 1. read 2. is 3.
