There are all kinds of things that it might be very useful ; for you to know as an inhabitant of Western civilization; and the New Testament,you might find out, would rank kind of down on the list of those kinds of things.
作为西方文明的一分子,有很多有用的东西可以学;,而新约，你会发现，与这些东西相比，排名比较靠后。

I'm walking along the list once, taking two things and saying, make sure the biggest one is next.

You could make a long list but it might include things Like the capacity for language and higher thought or abstract thought, conscience, self-control, free-will.
你也许能列出一个长单子，它可能包括以下东西,比如语言能力，高级或抽象思维能力，良心，自控力和自由意志。

Well, in giving these examples, I've already indicated at least two things that belong on the list.
在举例的过程中，我已经说明,起码有两样东西在名单上。
-
Let me also add that I have a reading list that has clickable things on it and also things that are on reserve in the library.
还有一点,我还有个阅读材料列表,其中有可点击的网络连接,也有可以在图书馆读到的内容

-
The worst case here is, the things not in the list in which case I've got to go all the way through the list to get to the end.
目标数不在数组里,这意味着我必须遍历数组中所有的元素,好，说完了这些。
-
If we look back at that long, open-ended list of things that were good or bad, we'll find that mos of the things on that list are instrumentally good.
再看那个长长的没有结尾的,好的或坏的东西的名单，我们会发现上面很多东西,都是有好的利用价值。
-
Well let's see. My fall back is, I could just do linear search, walk down the list one at a time, just comparing those things. OK. So that's sort of my base. But what if I wanted, you know, how do I want to get to that sorted list? All right?
我只能做线性搜索了,一次遍历一遍列表，一个一个比较，但如果我想要,那怎样得到有序的列表呢？,现在的一个问题是，我们排序之前？
-
It took me seven comparisons, because I can take advantage of the fact I know I only ever have to look at the first element of each sub-list. Those are the only things I need to compare, and when I run out of one list, I just add the rest of the list in.
进行了7次对比，因为我可以利用我知道的优势：,每次只需要比较每个子列表的第一个元素,那才是我需要进行对比的内容,当一个列表的元素处理完了,只需要将另一个列表剩下的元素直接添加进去。
-
Most of the good things on that list were instrumentally good.
名单上多数好的东西都归结为好的利用价值。
-
I think the easiest way to look at what this does, is let's take a really simple example- I want to make sure I put the right things out- I've got a simple little list of values there.
到底做了什么，就是让它跑一个简单的例子，我想要确信我找到了正确的元素-,这里我用一个简单的小的列表-,如果我去代码里面看。
-
So, for example: in this case, my list is a bunch of integers. And one of the things I could take advantage of, is I'm only going to need a finite amount of space to represent an integer.
列表是一系列整数,要注意的这里的优势能够,用有限的空间来表示整数,例如，如果我想要操作。
-
That isn't there. So it couldn't do it, so instead that's what append is for, is to stick things on to the end of the list.
也就是说不存在，因此没法进行指向绑定的，更改，因此这个命令并不像append那样，会在list的最后添加元素。
-
Basic idea, before I even look at the code, is pretty simple. If I've got a list that is sorted, in let's call it, just in increasing order, and I haven't said what's in the list, could be numbers, could be other things, for now, we're going to just assume they're integers.
我们可以说基本的思想是很简单的,如果我有一个排好序的数组，让我们认为这个数组是递增的吧，我并没说数组里元素是什么，可能是数字，也可能是其他的东西，现在我们假设是integer类型的数字吧，最简单的方式就是这么做了：
-
To get any location in memory, to get to any value of the list, I simply have to say which element do I want to get, I know that these things are stored in a particular size multiply that index by 4, add it to start, and then it's in a constant amount of time I can go to that location and get out the cell.
取得列表中的任何一个值,简单说来，想要取得列表中的任何元素,我知道这些元素存在特定的大小中,把下标乘以4，加到start上,然后定位到内存单元，并取出值就是固定的时间了,好的，如果元素以固定大小存储。
-
b OK. In this example I'd use b. All right, as b get-- b is the thing that's changing as I go along here, but it could be things like, how many elements are there in a list if the input is a list, could be how many digits are there in a string if the input's a string, it could be the size of the integer as we go along. All right.?
好，在这个例子里我会用，因为b是一直在变的东西,但是也可能是如下情况：,如果输入是数组的话,变化的就是数组的元素数，如果输入是字符串的话,变化的就是字符串的长度，如果是integer的话,可能就是这个数的大小，对不对？

And all these other things are not part of the list."
其他东西都不在书目里面“
