  答案与题解:

  1.A表达“雪崩是山上可能发生的最大危险之一”的意思,因此应该选择among(在……之中)。

  2.B从该句的语法结构上来看,此处需要一个关系代词,代替slope,所以that是最佳选择。选项A、C、D均不符合语法。

  3.B选项A不符合语法,c和D符合语法,但不符合常识:过度的雪的积压可能导致雪崩,

  而不是必定导致雪崩。所以,B是最佳答案。

  4.C该句的主语是Determining the critical load,从上下文来看应该使用一般现在时,所以C是正确答案。

  5.C要确定本题答案的一个有效的方法是排除法。a.10w weight/form work of avalanche都不合逻辑,只有a low risk of avalanche符合上下文的意思。下面的句子解释了low risk of avalanche的道理,更证实了选risk是正确的。

  6.D第6和第7题可以一起考虑。整个句子的意思是:在坡度大的坡上,雪不会大量堆积。

  在较为平坦的坡面,雪不会轻易滑动。

  7.B(见6)

  8.B理解了句子的意思就不难判断选项:雪在静止状态下,角度在35_45度之间,最可能发生人为触发的雪崩。between:在……之间。

  9.C这个句子说明的是什么样的山坡最易发生雪崩,即,A slope that is flat enough to hold snow but steep enough to ski。flat在此做“平坦”解,与后面的steep形成反义。

  10.A句中的that is表明,后半部分是对前半部分的进一步说明。所以,这里的选择要根据下文的意思判断。use是最佳选择,整个句子的意思是:山坡被滑雪者使用的越多,雪崩就越可能发生。 、

  11.D尽管选项A、B和D都能和continuous搭配,从全段的内容判断,只有process是最佳选择,因为该段描写的是如何防备雪崩,及如何做好安全措施等一系列问题。

  12.A选项A、B、c都可以与weather搭配,但是根据上下文,只有A最为符合文章的内容。

  13.B选项A不符合句子的意思;c不能和risk搭配;D也不符合句子的意思,因为不可能完全消除雪崩的隐患。

  14.C该句主句使用的是被动语态,第二个动词是pay attention t0的被动形式。l选项A、B、D均不符合句子的意思。

  15.A该句是作者给出的一系列忠告之一,即,认真观察地形,注意明显的雪崩路径:没有植物或植物被毁坏的地方。选项8、C、D均不符合句义。

  Taking a Nap During the Day

  Medical experts say most Americans do not get  1  sleep. They say more Americans need to rest for a short period in the middle of the day. They are advising people to sleep lightly before  2  with other activities.
