例如，普通文件应该有一条尾记录，说明文件中的总记录数，以及关键字段的合计。

For example, flat files should have a trailer record telling the total of records in the file and an aggregate of the key fields.

2007年，科学家们记录了一只黑尾豫在九天之内以平均每小时35英里(56千米)的速度从阿拉斯加飞到了新西兰，飞行里程超过7000英里(11500千米)。

In 2007 scientists recorded a godwit flying more than 7, 000 miles (11, 500 kilometers), from Alaska to New Zealand, in nine days at an average speed of about 35 miles an hour (56 kilometers an hour).

如果您要从尾到头读取文件的内容(例如，为了分析日期从近到远排列的日志记录)，那么使用CPAN模块File： ReadBackwards。

If you need to read the contents of a file backwards (for instance, to analyze a log in reverse order), use the CPAN module file: : ReadBackwards.

And the point of this is so that you don't come to class heads down the whole time thinking everything I say is absolutely worthy of being written down.

这样做的意义在于你不必,从头到尾去考虑要不要,把我所说的都记录下来。

In binary search-- ah, there's that wonderful phrase, this is called a version of binary search just like you saw bin-- or bi-section methods, - when we were doing numerical things- in binary search, I need to keep track of the starting point and the ending point of the list I'm looking at.

就是当我们处理数字的时候，所称的二分检索，在二分法搜索中,我需要记录区间的开始点和尾点，初始化的时候就是-,问题输入的开始点和尾点，当我开始做测试的时候,我想要做的就是去取中值点。
