题目内容

result it is, you’d better check it in practice yourself.

A．Whatever obvious a	B．However obvious
C．However obvious a	D．However a obvious

解析试题分析：句意：这个结果不论有多么的明显，你最好自己在实践中检测好它。obvious明显的，为形容词，与however连用，引导让步状语从句，故选C
考点：however引导从句的用法
点评：however一词的用法如下：1. 用作副词
(1) 表示让步：意为“无论如何”“不管怎样”，用来修饰形容词或副词，其词序为：however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能，用以引导让步状语从句。
(2) 表示转折：尤其用于谈及一个既成事实时，表示转折，其意为“可是”“仍然”等。可放在句首、句中或句末，通常用逗号与句子其他成分隔开。

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increase the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
