每日科技英文38: 操作系统与内核的概念

2017-12-06  本文已影响246人  随风而行之青衫磊落险峰行

今日要点:

  1. 操作系统和内核
  2. 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.

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.

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

  1. 间接宾语:授予的对象 (主语先接触的事物)
  2. 直接宾语:授予的物品 (主语后接触的事物)

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!
