英语阅读理解，具体看下面,如何做英语阅读理解

Are you happy with your teeth?
In the last five years, teeth whitening has become very popular among young Americans. Now the trend(潮流)has come to China. If you turn on the TV you can see the Hong Kong pop star Karen Mok showing her bright white teeth, saying. “Want to be like me? Use white teeth strips(牙贴)!” You may even have decided to buy one.
But wait a minute. Dentists have something to say. They think that kids should not use whitening products until they are 1 6 or even older.
“We don’t know what will happen yet," says Dr. Nasrin Azim, a dentist in Chicago. “Studies have not been done on young people. I wouldn’t do teeth whitening on anyone under 18.”
The problem with whitening lies in the pulp(牙髓), the innermost(最深处的) part of the tooth. It has the tooth’s nerve ending. When we eat very hot or cold things, it’s the pulp that hurts. Kids have larger pulps. The larger pulp might make teeth more sensitive(敏感的) to whitening and get hurt.
Another problem is that the gums(牙床) around the teeth usually change shape with age. So if someone whitens his or her teeth during childhood, the darker, natural colour might show later around the gum line. At that time, your teeth will show two colours. And the darker colour is difficult to whiten。
The main focus of this article is on dental(牙齿的) ______.
A. care B. beauty C. cleaning D.illness
为什么很多人选C，如果光是因为这篇文章讲的是洁牙有关的方面就选C是不是有些片面，我这篇文章主要还是讲的为了保护我们的牙齿而不要去洁牙，我觉得应该选A，不知道大家怎么看，急求解？
还有为什么英语阅读理解的文意理解题我总是理解有偏差？应该怎样理解，只看表面还是看内涵。

Answer 1

这篇文章是围绕着“teeth whitening”（牙齿美白）这个中心展开的，题目中的选项C意思是清洁，而美白和清洁应该是两个概念，就像美容和洗脸是两个概念一样。因此，答案应该选A， 意思是：牙齿护理。

阅读理解题，顾名思义，就是要对阅读的信息进行理解，在拿到一篇文章后，首先是需要理解句子的意思，所以，单词和短语掌握的程度会直接影响到答题。因此，只要你平时多阅读，多练习，自然而然的就会得到提高了。

祝你学习进步！

Answer 2

这文章看开头，说牙贴的，然后第二段话锋一转，说小孩不能用牙贴对牙齿不好~ 第四段就是说为什么不好，小孩牙齿神经末梢很敏感，牙贴会对小孩牙齿的神经末梢带来伤害，也会对牙床带来影响、
现在就可以看了，整篇文章说的是牙齿的保护，而不是清洁牙齿，牙齿的清洗、
牙齿的清洗整篇文章就没说，如果文章要说牙齿清洗的话，会介绍如何清洗，用什么清洗。
而不是说牙贴对牙齿有什么影响，有什么危害~
所以该选A
