【解析】

这是一篇说明文，文章主要讲述眼睛的重要性，只有在眼睛看不见的时候人们才能意识到眼睛有多么重要；文章介绍了眼睛出现的问题，近视、远视、散光、白内障以及眼盲；并讲述了有两只好眼睛对判断物体的距离很重要。

1.

句意：只有当我们完全不能看见的时候，我们才意识到 我们的眼睛有多么重要。

remind提醒；receive收到；review复习；realize意识到，实现。根据“how important our eyes are”可知此处用动词realize表示“意识到眼睛的重要性”。故选D。

2.

句意：其它的每样东西看起来不清晰。

unhappy不开心的；unpleasant不愉快的；unclear不清晰；unfair不公平的。根据“People who are near-sighted can only see things that are very close to their eyes”可知近视的人只能看到离眼睛很近的东西，此处用unclear表示“不清晰的”。故选C。

3.

句意：一个做了很多工作的人，比如写作、阅读和缝纫，后来会变得近视。

what什么；who谁；when什么时间；which哪一个。此处是定语从句，先行词person是表示人，从句用who指代人，在从句做主语。故选B。

4.

句意：远视的人遭遇相反的问题。

right正确的；same相同的；wrong错误的；opposite相反的。根据“far-sighted”可知远视与近视相反，此处用opposite。故选D。

5.

句意：他们能看见远处的东西，但是他们在读书时有难度，除非他们把书拿的有一臂之远。

difficulty困难；fun乐趣；time时间；experience经验。此处用固定结构have difficulty in doing表示“做某事有困难”。故选A。

6.

句意：如果他们想做很多阅读，他们也必须戴眼镜。

shopping购物；cleaning清扫；reading阅读；fishing钓鱼。根据前文“have difficulty in reading a book unless they hold it at arm's length”可知大量阅读需要戴眼镜。故选C。

7.

句意：有些人的眼睛因为白内障变得浑浊。

cloudy有云的，不清澈的，浑浊的；sunny晴朗的，有太阳的；windy有风的；rainy下雨的。根据“because of cataracts”可知此处指的是眼睛变得不清澈，用cloudy。故选A。

8.

句意：每一只眼睛从稍微不同的角度看事物。

each（两个的人或物中）每个，强调个体概念；every（与单数名词连用，指整体中的）每一个，强调全体的概念；both二者都；all三者或以上都。根据前文“Having two good eyes”可知此处指的是两只眼睛中的每一只，用each。故选A。

9.

句意：为了证明这一点，你自己从一只眼睛看一个物体，然后再从另一只眼看相同的事物。

yourself你自己；himself他自己；herself她自己；myself我自己。根据后文“You will find the object's relation to the background”可知此处指的是你自己做测试来证明这一点，用yourself。故选A。

10.

句意：这两只眼睛视野的不同可帮助我们判断一个物体有多远。

helps帮助；makes制作；encourages鼓励；agrees鼓励。此处用动词helps表示“帮助，有助于”。故选A。
