阅读课文中的语段,回答问题。

  不同的植物为什么开花的时间不同呢?原来,植物开花的时间,与温度、湿度、光照有着密切的关系。比如,昙花的花瓣又大又娇嫩,白天阳光强,气温高,空气干燥,要是在白天开花,就有被灼伤的危险。深夜气温过低,开花也不适宜。长期以来,它适应了晚上九点左右的温度和湿度,到了那时,便悄悄绽开淡雅的花蕾,向人们展示美丽的笑脸。还有的花,需要昆虫传播花粉,才能结出种子,它们开花的时间往往跟昆虫活动的时间相吻合。

1.在文中找出下列词语的反义词。

弱(  )  低(  )  潮湿(  )  枯萎(  )  安全(  )

2.填空。

  昙花开花的时间一般在________,这是因为它的花瓣又____又____,容易被强烈的________灼伤;另外,还因为它适应晚上九点左右的________和________。又由于昙花开花的时间非常短,所以人们常用“________”来形容美好的事物难得一见。

3.先想一想这段话是围绕哪句话来写的,用“~~”画出来,再完成填空。

从修辞角度讲,这是一个________句。

4.用“____”画出叙述不同植物开花时间不同的原因的句子。

(46)A long-held view of the history of the English colonies that became the United States has been that England’s policy toward these colonies before 1763 was dictated by commercial interests and that a change to a more imperial policy generated the tensions that ultimately led to the American Revolution. In a recent study, Stephen Saunders Webb has resented a formidable challenge to this view. According to Webb, England already had a military imperial policy for more than a century before the American Revolution. He sees Charles Ⅱ, the English monarch between 1660 and 1685, as the proper successor of the Tudor monarchs of the sixteenth century and of Oliver Cromwell, all of whom were bent on extending centralized executive power over England’s possessions through the use of what Webb calls "garrison government. " Garrison government allowed the colonists a legislative assembly, but real authority, in Webb’s view, belonged to the colonial governor, who was appointed by the king and supported by the "garrison," that is, by the local contingent of English troops under the colonial governor’s command.

According to Webb, the purpose of garrison government was to provide military support for a royal policy designed to limit the power of the upper classes in the American colonies. (47) Webb argues that the colonial legislative assemblies represented the interests not of the common people but of the colonial upper classes, a coalition of merchants and nobility who favored self-rule and sought to elevate legislative authority at the expense of the executive. It was, according to Webb, the colonial governors who favored the small farmer, opposed the plantation system, and tried through taxation to break up large holdings of land. Backed by the military presence of the garrison, these governors tried to prevent the gentry and merchants, allied in the colonial assemblies, from transforming colonial America into a capitalistic oligarchy.

(48) Webb’s study illuminates the political alignments that existed in the colonies in the century prior to the American Revolution, but his view of the crown’s use of the military as an instrument of colonial policy is not entirely convincing. England during the seventeenth century was not noted for its military achievements. Cromwell did mount England’s most ambitious overseas military expedition in more than a century, but it proved to be an utter failure. Under Charles II, the English army was too small to be a major instrument of government. (49) Not until the war in France in 1697 did William III persuade Parliament to create a professional standing army, and Parliament’s price for doing so was to keep the army under tight legislative control. (50) While it may be true that the crown attempted to diminish the power of the colonial upper classes, it is hard to imagine how the English army during the seventeenth century could have provided significant military support for such a policy.
