第3题：
阅读下列代码 public class Jixiangwu{ public static void main(String[]args){ String[]stars={"贝贝","晶晶","欢欢","迎迎","妮妮"}; System. out. println("你抽取的奥运吉祥物是"+"“" +stars[(int)(stars. ______* Math. random())]+"”"+"!"); } } 为保证程序能正确执行，程序中下画线处应填写的是
A．long
B．width
C．wide
D．length
解析：数组只有对其求长度有意义，其他long、width和wide不属于Java中的关键字或数组类型的方法。本题程序中Math. random()生成一个0～1的double型的随机数，乘以数组长度取整将会得到大于等于0而小于等于4的整数，再作为数组下标对数组取值。

第9题：
So Many"Earths"
The Milky Way（银河）contains billions of Earth-sized planets that could support life.That's the finding of a new study.It draws on data that came from NASA's top planet-hunting telescope.
A mechanical failure recently put that Kepler space telescope out of service.Kepler had played a big role in creating a census of planets orbiting some 170,000 stars.Its data have been helping astronomers predict how common planets are in our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth.
The authors of a study,published in The Proceedings of the National Academy of Sciences,conclude that between 14 and 30 out of every 100 stars,with a mass and temperature similar to the Sun,may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth's,but no more than twice that big.The planet also would have to orbit in a star's habitable zone.That's where the surface temperature would allow any water to exist as a liquid.
The new estimate of how many planets might fit these conditions comes from studying more than 42,000 stars and identifying suitable worlds orbiting them.The scientists used those numbers to extrapolate（推算） to the rest of the stars that the telescope could not see.
The estimate is rough,the authors admit.If applied to the solar system,it would define as habitable a zone starting as close to the Sun as Venus and running to as far away as Mars.Neither planet is Earthlike (although either might have been in the distant past).Using tighter limits,the researchers estimate that between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to complete a yearly orbit.
Four out of every 100 sunlike stars doesn't sound like a big number.It would mean,however,that the Milky Way could host more than a billion Earth-sized planets with a chance for life.
A:Right
B:Wrong
C:Not mentioned
第二段最后一句表明，开普勒太空望远镜主要关注与地球有相似环境的星球，所以选择A项。
第三段第二句表明，可以让生命存在的星球的直径至少要和地球的直径一样大，但不会超过地球直径的两倍。由此不难推断出其应该不比地球小，所以选择B项。
第三段第三、四句表明，适合人类居住的星球必须与它所环绕的恒星有一个适于居住的距离，以保证星球表面的温度能够允许液态水的存在。地球不仅适合人类居住，而且还绕着太阳运行。由此可知，题干表述正确。
第四段第一句表明，该项新评估源于对超过4.2万颗星球的分析，而非源于对17万颗星球的分析，所以选择B项。
第五段第一句表明，研究人员承认这项评估是粗糙的，即不精确的，所以选择A项。
文章第一段指出，这次的调查结果是新的发现，但通篇文章并未提到这是对可能有生命存在的星球的首次研究。
第10题：
Mau Piailug,Ocean Navigator
Mau sailed from Hawaii to Tahiti using traditional methods.
In early 1976,Mau Piailug,a fisherman,led an expedition in which he sailed a tradi-tional Polynesian boat across 2,500 miles of ocean from Hawaii to Tahiti.The Polynesian Voyaging Society had organised the expedition.Its purpose was to find out if seafarers（海员） in the distant past could have found their way from one island to the other without naviga-tional instruments,or whether the islands had been populated by accident.At the time,Mau was the only man alive who knew how to navigate just by observing the stars,the wind and the sea.
He had never before sailed to Tahiti,which was a long way to the south.However,he understood how the wind and the sea behave around islands,so he was confident he could find his way.The voyage took him and his crew a month to complete and he did it without a compass or charts.
His grandfather began the task of teaching him how to navigate when he was still a baby.He showed him pools of water on the beach to teach him how the behaviour of the waves and wind changed in different place.Later,Mau used a circle of stones to memorise the positions of the stars.Each stone was laid out in the sand to represent a star.
The voyage proved that Hawaii's first inhabitants came in small boats and navigated by reading the sea and the stars.Mau himself became a keen teacher,passing on his traditional secrets to people of other cultures so that his knowledge would not be lost.He explained the positions of the stars to his students,but he allowed them to write things down because he knew they would never be able to remember everything as he had done.
A:Right
B:Wrong
C:Not mentioned
题干意为“玛乌很熟悉塔希提岛周围的海洋。”关键词是Tahiti。依据此关键词，可在文中第二段前两句找到相关叙述：“He had never before sailed to Tahiti, which was a long way to the south.However,he understood how the wind and the sea behave around islands, so he was confident he could find his way.”（他从来没有航行到过塔希提岛，从塔希提岛到南方是一段很长的路程。然而他知道岛周围的风和海洋是怎么活动的，所以他自信可以找到路。）由此可知，虽然玛乌没有去过这个岛，但是他很熟悉海洋，故此题说法是“正确”的。
题干意为“玛乌买不起罗盘和图表。”关键词是compass和charts。依据关键词，可在文中第二段最后一句找到相关叙述：“The voyage took him and his crew a month to complete and he did it without a compass or charts.”（这次航行要花费他和船员们一个月的时间，而且他们航行的时候没有罗盘和图表。）由此可知，他们航行确实用不到罗盘和图表，但是文中并没提到玛乌买不起这些工具，故此说法为“未提及”的。
题干意为“玛乌从祖父那里学到了航海技术。”关键词是grandfather。依据此关健词，可在文中第三段第一句找到相关叙述：“His grandfather began the task of teaching him how to navigate when he was still a baby.”（当他还很小的时候，他的祖父就开始教他航海。）故此题说法为“正确”的。
题干意为“玛乌用石头记忆天空中星星的位置。”关键词是stones和stars。 依据关键词，可在文中第三段倒数第二句找到相关叙述：“Later, Mau used a circle of stones to memorise the positions of the stars.”（之后，玛乌用一圈石头来记忆星星的位置。）故此题说法是“正确”的。
题干意为“夏威夷最早的居民能读写。”关键词是first inhabitants of Ha-waii。依据关键词可在文中最后一段第一句找到相关叙述：“The voyage proved that Hawaii's first inhabitants came in small boats and navigated by reading the sea and the stars.”（此次航行证明，夏威夷最早的居民是乘小船来到这里的，并通过观察海洋和星空来航行。）文中的 reading是观察的意思，除此之外并没有提到这些最早的居民会不会读写，故此说法是“未提及”的。
题干意为“玛乌希望自己的学生们能立刻记住星星的位置。”关键词是 students。依据此关键词，可在文中最后一句找到相关叙述：“He explained the positions of the stars to his students,but he allowed them to write things down because he knew they would never be able to remember everything as he had done.”（他向学生们解释星星的位置， 但他允许学生把知识点写下来，因为他知道他们不可能像他一样记住所有东西。）故此题说法为“错误”的。
