今日要点:
- 操作系统和内核
- 授予动词
operating system(操作系统)
A piece of software that makes multitasking possible. An operating system typically consists of a set of function calls, or software interrupts, and a periodic clock tick. The operating system is responsible for deciding which task should be using the processor at a given time and for controlling access to shared resources.
-
a piece of: 量词,一份,一张,一片...
-
to make sth possible: 使...成为可能
-
to consist of: 由...组成
-
a set of: 量词,一些列...
-
a periodic[ˌpɪəriˈɒdɪk] clock tick: 定期时钟周期
-
be responsible for doing sth:负责做某事
-
for deciding which task should be using the processor at a given time
-
for controlling access to shared resources.
-
上面两句接在be responsible后面,and连词,并行
使多任务能够实现的一个软件。一个操作系统典型地由一个函数调用集、软件中断和定期时钟周期组成。一个操作系统负责决定哪一个任务在给定的时间将使用处理器,并且控制对共享资源的访问。
Kernel(内核)
An essential part of any multitasking operating system, the kernel contains just the scheduler and context-switch routine.
-
An essential[ɪˈsenʃl] part of: 本质部分
-
scheduler: 调度
任何多任务操作系统的本质部分,内核仅仅包含调度程序和上下文切换进程。
今日语法小知识: 授予动词
-
授予动词,英语中的一种词汇种类,需要接两个宾语。
-
授予动词属于及物动词的一种,此类动词需要接两个宾语。
- 间接宾语:授予的对象 (主语先接触的事物)
- 直接宾语:授予的物品 (主语后接触的事物)
- 有特定句型: 主语+授予动词+间接宾语(授予对象)+直接宾语(被授予的东西)
理论比较无聊,直接上例子:
I will give you this watch.
Please lend me your book.
这种 to give sb sth / to lend sb sth这种类型的句型都是授予句型
上面句型是先sb,后sth。也可以倒过来,先sth,后sb,此时需要加to,例如上面句型的改写如下:
I will give this watch to you.
Please lend your book to me.
给某人某物 = 把某物给某人,很通顺啊!
