问题 单项选择题

茶叶这一源于中国的特殊饮料,对于我们中国人来说实在是太普通了,它已深深地于我们的日常生活之中,以至于我们对其作用和影响______。 填入横线部分最恰当的一项是( )。

A.根植 耳熟能详

B.渗透 耳熟能详

C.根植 熟视无睹

D.渗透 熟视无睹

答案

参考答案:D

解析: “根植”,扎根,比喻深入到人或事物中去,打下基础。“渗透”,比喻某种事物或势力逐渐进入其他方面。根植多用比喻义。茶叶是具体的事物,第一空应选择“渗透”。“耳熟能详”,指听得多了,能够说得很清楚、很详细。“熟视无睹”,看惯了就象没看见一样。也指看到某种现象,但不关心,只当没有看见。由句中的“对于我们中国人来说实在太普通了”,说明茶叶对中国人来说已经看惯了,就像没有看见一样。第二空应选择“熟视无睹”。

单项选择题


The sun today is a yellow dwarf star. It is fueled by thermonuclear reactions near its center that convert hydrogen to helium. The sun has existed in its present state for about 4 billion, 600 million years and is thousands of times larger than the Earth.
By studying other stars, astronomers can predict what the rest of the sun’s life will be like. About 5 billion years from now, the core of the sun will shrink and become hotter. The surface temperature will fail. The higher temperature of the center will increase the rate of thermonuclear reactions. The outer regions of the sun will expand approximately 35 million miles, about the distance to mercury, which is the closest planet to the sun. The sun will then be a red giant star. Temperatures on the earth will become too hot for life to exist.
Once the sun has used up its thermonuclear energy as a red giant, it will begin to shrink. After it shrinks to the size of the earth, it will become a white dwarf star. The sun may throw off huge amounts of gases in violent eruptions called nova explosions as it changes from a red giant to a white dwarf.
After billions of years as a white dwarf, the Sun will have used up all its fuel and will have lost its heat. Such a star is called a black dwarf. After the Sun has become a black dwarf, the earth will be dark and cold. If any atmosphere remains there, it will have frozen onto the earth’s surface.

It can be inferred from the passage that the sun ______ .

A.is approximately halfway through its life as a yellow dwarf

B.has been in existence for 10 billion years

C.is rapidly changing in size and brightness

D.will continue as a yellow dwarf for another 10 billion years
