閱讀理解 　　Jupiter’s Moons and How They Travel 　　The many moons of Jupiter travel around the planet in different directions(方向)． 　　Jupiter is the largest planet in our solar system．Over the years, scientists have found that Jupiter has its own small solar system．Earth has one moon．Jupiter has at least sixteen and probably more． 　　Since there are so many moons, scientists began to number them．The numerals(numbers)tell the sequence, or order, in which the moons were found．They were slower to name the moons．All of Jupiter’s moons now have a name as well as a number． 　　The first five moons to be discovered are known as the “inner moons”．But they are not the closest to the planet．The closest is only 127,600 kilometers away from Jupiter．All the inner moons circle the planet in counter-clockwise direction, that is, opposite of the hands of a clock． 　　Jupiter’s middle group of moons are at least 11,100,000 kilometers from the planet．They also move in a counter-clockwise motion(moving)．The four farthest moons are at least 20,700,000 kilometers away．These are called “outer moons”．They circle in a clockwise motion． 　　How many more moons do you think will be discovered? (1) What does “solar system” in this article mean?________ [　　] A． 銀河系 B． 宇宙空間 C． 流星雨 D． 太陽系 (2) Things that travel in the same direction as the hands of a clock are said to be traveling in a________． [　　] A． clockwise direction B． counter-clockwise direction C． same direction D． different direction (3) Jupiter’s ________group of moons travel in a clockwise direction． [　　] A． planets B． inner C． middle D． outer (4) The numbers given to Jupiter’s moons tell ________． [　　] A． the order in which they were discovered B． the order in which they travel C． the order of their distance from Jupiter D． the order of names (5) According to the passage，which of the following statements is true? [　　] A． None of Jupiter’s moons have names． B． Most of Jupiter's moons circle clockwise． C． Jupiter's inner moons were discovered first． D． Jupiter is the nearest planet to the earth． (6) How far away are the middle group of moons from Jupiter? [　　] A． It’s not mentioned． B． 11,100,000 kilometers away． C． 127,600 kilometers away． D． 20,700,000 kilometers away．

Answer 1

答案：1．D;2．A;3．D;4．A;5．C;6．B;
解析：

(1)	文中介紹Jupiter(木星)是最大的行星，地球只有一個月亮，而木星至少有16個，甚至更多．由此可見，solar system即為太陽系，木星同地球一樣都是太陽系中的行星．
(2)	“clockwise direction”指“順時針方向”．文中對“counter-clockwise direction”的解釋是“opposite of the hands of a clock”，即“逆時針方向”．
(3)	最遠的四個月亮稱為“outer moons”，它們以順時針方向轉(zhuǎn)．
(4)	由文中“The numerals(numbers)tell the sequence, or order, in which the moons were found．”這句話可知．
(5)	統(tǒng)觀全文，可知選項A、B不符合文意，根據(jù)常識判斷，選項D也不正確．再由環(huán)繞木星旋轉(zhuǎn)的月亮團以依次發(fā)現(xiàn)的時間為序，由此推理可得出“the inner moons were discovered first”．
(6)	在文中可找到“Jupiter's middle group of moons are at least 11,100,000 kilometers from the planet．”．根據(jù)這一句話的意思，便可得知此題答案為B． 　　這是一篇關(guān)于宇宙知識的科普短文．在太陽系中，木星是最大的一顆行星．圍繞其旋轉(zhuǎn)的衛(wèi)星有很多．科學(xué)家們首先發(fā)現(xiàn)的是離它較近的五顆名叫“內(nèi)部月亮”的衛(wèi)星，它們是以逆時針方向繞其旋轉(zhuǎn)的．木星的不計其數(shù)的中間月亮團也是以逆時針方向繞其旋轉(zhuǎn)的．但它的最近的四個“外部月亮”卻是以順時針方向繞其旋轉(zhuǎn)的．
