问题 As Venus is the brightest,it is the most conspicuous of the planets.It is named after the Roman goddess of love and beauty,and is probably more nearly like the earth than any other planet.During the late summer and early autumn it may be seen as a bright evening“star”at a point in the sky near the place where the sun sets.Its brightness is probably due to the reflection of sunlight from great banks of vapor or clouds that surround the planet.Perhaps you have,after sundown,noticed the effect produced by sunlight reflected upon a white cloud.
    Although Venus when nearest to the earth is 27.5 million miles away,it is always much nearer to the earth than any other planet.Its diameter(直径)is about 7726 miles.Venus revolves in its orbit(沿轨道旋转)around the sun in seven and one.half of our months,that is 225 of our days.Because of its dense atmosphere,its brightness,and the absence of fixed markings,astronomers have not been able to agree upon the length of its day;observations support the view that the same hemisphere(半球)of Venus is always toward the sun.
The word“conspicuous’’in Paragraph 1 most probably means“_________”.

选项 A、brilliant
B、beautiful
C、colorful
D、noticeable

答案D

解析 根据文章第一段对金星的描述,金星是最明亮的,它在夏末和初秋的晚上看上去像是一颗明亮的星星,可知金星应该是很显眼的,很容易被看到的,所以推断conspicuous应该与noticeable“引人注意的,显著的”意思相近,故选D。
