简述蒸汽机的工作原理？

阅读下列材料

材料一：公元前356年，商鞅在秦孝公的支持下开始变法。其变法的主要内容包括：（1）国家承认土地私有，允许自由买卖；（2）奖励耕战：生产粮食和布帛多的人，可以免除劳役；在战争中立了功的人，按照军功的大小授予爵位、土地和住宅；（3）建立县制：把全国合并为41个县，县的长官称县令，由国君直接任免。

材料二：商鞅在变法之前曾与守旧势力代表人物有过一场舌战，面对别人的质疑，商鞅侃侃而谈：“商汤和周武王，没有按照老办法治理国家，却因此得了天下；夏桀和商纣墨守陈规，结果国家灭亡。可见治理国家不一定按照老规矩……如果可以强国，就不必仿效过去；如果有利于百姓，就不必遵循旧的礼俗。”

请回答：

（1）从材料一可以看出商鞅变法对传统旧制度的冲击非常大。结合材料二，你认为是什么原因促使商鞅有如此的胆量和勇气主持这场变法运动？

（2）请你说一说，商鞅变法的哪一条措施与富国强兵的目的最直接、最密切？

（3）商鞅最终死于非命，死在反对新法的旧贵族手中，那么这是否说明商鞅变法最终失败了呢？请阐述你的理由。

The US will seek to expand its own oil production in an attempt to reduce dependence on imported oil and bring down fuel prices , President Obama says . New contracts for exploration will be signed in non-protected areas of Alaska and in the Gulf of Mexico.

In his weekly speech , the President insisted the US could reduce its need for imported oil and improve safety. Using his speech to tell Americans that he understood their concerns about rising prices, President Obama focused particularly on the price of fuel, which has risen in recent months.

US consumers have historically enjoyed cheap fuel , but have seen prices rise in recent months even though US oil production in 2010 reached its highest level for seven years.

Although the oil spill in the Gulf of Mexico in 2010 was serious, Mr Obama said the Gulf remained a key part of the country’s future energy supply.

The President’s proposals (议案）come after Republicans (共和党人） introduced a series of proposals that would expand and speed up oil and gas production.

The White House has criticized the Republican proposals for safety reasons , but Mr Obama was clear in his speech that he felt safety and environmental standards could be maintained even though production might rise.

“ I believe that we should continue to expand oil production in America —even as we increase safety and environmental standards ,”he said.

“As a nation, we should be investing in the clean, renewable sources of energy that are the solution to high gas prices.”

Mr Obama has previously called for a step-change in energy policy, saying the US must move towards getting 80%of its electricity from clean energy sources by 2035.
