You can also perform a test. Take some of the material and add enough water to it to make it seem like you are making bread.

And then we're going to try a demo to see if we can convince ourselves that the kind of calculations we make work out perfectly, and we'll do a test up here about half way through class.

然后我们将会尝试演示去看看,是否可以确信我们能够很好的,做出这个类型的计算，我们将在课程中做一个测试。

Some want an independent review. And the trial's researchers, like Dr.Nelson Michael, of the Walter Reed Institute of Research in the United States, say it's unclear what difference the findings will make for areas like Africa where rates of HIV/AIDS are much higher than among the test population and where there are many strains of the virus.

And that idea was, we make a guess in the middle, we test it so this is kind of a guess and check, and if the answer was too big, then we knew that we should be looking over here. If it was too small, we knew we should be looking over here, and then we would repeat.

这些有理数是有序排列的,然后我们的想法是,首先在中间取个数作为猜想数，然后对这个猜想数进行验证，如果由猜想数得到的答案太大,我们知道应该跳过，比猜想数大的那个区间，如果太小的话。
