今日要点:
- CISC和 RISC指令集计算机的定义
- 四大名词性从句
CISC（复杂指令集计算机）
Complex Instruction Set Computer. Describes the architecture of a processor family. CISC processors generally feature variable-length instructions, multiple addressing formats, and contain only a small number of general-purpose registers. Intel"s 80x86 family is the quintessential example of CISC. Contrast with RISC.
复杂指令集计算机。对一种处理器架构的描述。CISC处理器一般产生变长的指令，多种地址格式，并且仅仅有少量的通用寄存器。Intel的80x86家族是是典型的CISC处理器。相对于RISC而言。
architecture [ˈɑ:kɪtektʃə(r)]: 体系结构; 建筑学; 建筑风格; （总体、层次） 结构;
quintessential [ˌkwɪntɪ'senʃl]: 典型的，精髓的
contrast with: 与...相比
RISC（精简指令集计算机）
Reduced Instruction Set Computer. Describes the architecture of a processor family. RISC processors generally feature fixed-length instructions, a load-store memory architecture, and a large number of general-purpose registers and/or register windows. The MIPS processor family is an excellent example. Contrast with CISC.
精简指令集计算机。一个处理器族的描述。RISC处理器一般的特征是固定长度的指令集，一个负载储备存储结构，和大量通用寄存器，及寄存器窗口。MIPS处理器族是极好的例子。相对CISC而言。
今日语法小知识: 名词性从句
包括:
宾语从句(从句做宾语)
I am worried about whether he can do it.
我很担心他是否能做这件事。主语从句(从句做主语)
That he doesn't study makes me angry.
他不学习让我很生气。表语从句(从句在系动词后面做表语)
His suggestion is that we should stay calm.
他的建议是，我们应该保持冷静。同位语从句(比较特殊，下面会列出)
I’ve come from Mr wang with a message that he won’t be able to see you this afternoon．
news，idea，fact，promise，question，doubt，thought，hope，message，suggestion，words，decision，possibility等后面跟的从句是都是同位语从句
说实话，同位语从句你可以当成定语从句，没什么大区别，不影响你对语言的理解
宾语从句和表语从句仅仅是一般动词还是系动词区别而已，也没什么好区分的
今天开始增加难读单词的音标，本人从学习开始就习惯使用英国音标，就用英英标注。
