【题目】宇宙中的奇异现象

苏光路

行星不走寻常轨道

宇宙从表面看上去，繁星璀璨，和谐有序，好似一座上满发条，便可安然运行的钟表。其实，就像水面游动的鸭子，我们只看见它悠然平静的身体，看不见水下划动的双脚。一些天体运行在异常怪异的轨道上，连世界顶尖的天文学家也会被搞得一头雾水。比如距离地球200光年的“开普勒16B”，这颗冰冷荒凉的行星竟然围绕着两颗恒星公转，这是天文学史上不可思议的一幕。

天文学家一直以为，两颗恒星的引力会把行星的轨道扭曲搞乱，甚至会将其撕碎，总之，它们不可能和平共处。

但摆在人们面前的是，“开普勒16B”却正平静地在两颗恒星间转动，不慌不忙，有条不紊。在“开普勒16B”上每天傍晚上演双日落奇观，像科幻小说描述的一样神奇。

在宇宙中，如此靠近恒星的行星并不少见，甚至可以用司空见惯来形容。比如最近发现的WASP-18b，它距离恒星的距离比地球距离太阳近50倍，不到一天就可公转一周。

因为WASP-18b距离恒星太近了，导致它们彼此都有些扭曲，炽热的恒星将其表面炙烤得处于熔融状态，一百年后就会被恒星化掉。难以挣脱的引力还使得它越发地靠近恒星，所以毁灭的命运是注定无疑的了。

黑洞吞噬大恒星

2011年底，美国天文学家目睹了天文观测有史以来最大的爆炸，辐射光芒比1000亿个太阳都明亮，它就是人们一直在教科书上了解的“伽马射线暴”。

开始飞来的强光让科学家们莫名其妙，不知所措。伽马射线暴是转瞬即逝的闪光，过一小时又重现。与近半个世纪前观察情况不同的是，本次伽马射线暴尤其强烈，持续数小时后，仍不停释放X射线，且无停止的迹象。

持续观测，天文学家才弄明白事情的原委——遥远星系中一个超大质量的黑洞，从休眠状态中突然苏醒。起初几颗恒星围绕着这个黑洞旋转，保持在安全的范围之内。其中一颗渐渐地靠近黑洞，惊动了这个沉睡中的巨兽，它释放的巨大引力将靠近的恒星越拉越紧，甚至变形扭曲，最终将它撕裂。恒星的残骸在黑洞的四周打转，温度升至数百万度，两道耀眼的伽马射线暴骤然射向太空。

黑洞在吞噬恒星时，只掳去它一半的物质，另一半则被狠狠地抛出去。其过程是宇宙中最具暴力的事件，它们为此而散发的巨大能量，是人类难以想象的。

恒星离“家”去流浪

最新观测发现，一些恒星正以惊人的速度逃离银河系。此外，宇宙中流浪恒星的数量远比人们想象的要多，在回放哈勃太空望远镜保存的一系列资料后，对此现象天文学家终于给出了合理的解释。

物理学的定义是，引力会向内吸引，不会向外推开。可是天体物理的情况比较复杂，只有两个天体时，这个定义还有效，一旦多于两个天体，就会发生奇怪的事情，引力一样具有推离效应。只要角度与速度合适的话，它们不是相撞，而是一个会将另一个推开，前提是一定要有黑洞的参与。

比如有两颗超高速运行的恒星围绕着一个超大质量的黑洞旋转，在黑洞的引力作用下两颗恒星逐渐分离开，在合适的距离范围内，黑洞在以320万公里的时速弹射出一颗的同时，将另一颗吸入分解……

这使得无家可归的流浪恒星越来越多，它们闯入的威力足以破坏星系的安宁，甚至引发星系相撞的极端事件，这是重构宇宙的潜在力量。

【题目】Most kinds of rose plants come from Asia. But roses are also native to other areas including northwest Africa, Europe and the United States. In 1986, Congress chose the rose as American’s national flower. Technically, Congress and President Ronald Reagan declared it the “national floral emblem（国花）.” Whatever the name, the decision did not smell sweet to supporters of other popular flowers.

Some people say roses are difficult to grow. But you have a good chance of success if you start with a few suggestions from experts. You should plant your roses where they can get sunshine for about six hours on bright days. You can buy roses from a garden center or by mail order. You can buy potted roses, also known as container roses, or bare-root plants. Each kind has its fans.

Some gardeners say potted roses are easier to plant. They say the roots develop better. But Jeffrey Dinslage, an expert, points out that bare-root roses come without soil. So they weigh less to transport.

Another expert advises getting bare-root roses as close to planting time as you can.. If they arrive before you are ready to plant them, make sure the packing material is moist. Keep the plants in a cool, dark place. The resting plants have no leaves but still need water. When growing roses, the soil should feel moist deep down. Watering should be done in the morning.

But do not water too much. People often ask Jeffrey Dinslage about unhealthy discoloration on rose leaves. He says the spots are usually caused by too much water. After heavy rains or too much watering, he advises pulling away mulch, the substance used to protect the roots, to improve the quality of the soil, temporarily from around the roots. This will help dry the soil.

【1】From the first paragraph, we know that in the United States _______.

A．all the people like roses

C．some roses don' t smell sweet

D．there are some other popular flowers

【2】How many kinds of roses can you buy according to the passage?

D．Six．

【3】Why does Jeffrey Dinslage suggest planting bare-root roses?

A．They are easier to plant.

B．Their roots develop better.

C．They are cheap to transport.

D．Their leaves need no water.

【4】Which of the following is closest in meaning to the underlined word “moist”?

A．Slightly wet.

B．Pretty dry.

C．Too hard.

D．Lightly soft.

【5】According to Jeffrey Dinslage, people should _______ to avoid the sports on rose leaves.

A．not water roses in the morning

B．protect the roots of roses

C．improve the quality of the soil

D．not water roses very much
