列举4个托福写作中常用到的主体段素材
主体段的写作经常是很多同学头疼的问题。很多情况下因为一时之间想不到论证论据而导致作文失败的事例时有发生。这就要求同学们在平时备考的时候一定要多多积累相关的论证论据，以备不时之需。比如今天托福范文TOEFL写作栏目为大家例举的这些例证就是我们平时作文中经常可以用到的。
(一)Winston Churchill
In the early 1930s, Conservative M.P. Winston Churchill issued unheeded warnings of the threat of Nazi aggression from his seat on a House of Commons backbench.
With German tanks racing across France, Churchill spoke to the British people for the first time as prime minister, and pledged a struggle to the last breath against Nazi conquest and oppression.
In the summer of 1940, the democracies of continental Europe fell to Germany one by one, leaving Great Britain alone in its resistance to Adolf Hitler. The Nazi leader was confident that victory against Britain would come soon, but Churchill prophesied otherwise, telling his countrymen that the Battle of Britain would be "their finest hour."
(二)Bill Clinton
In 1994, President Clinton authorized a military operation to overthrow Haiti's military dictators and restore its democratically elected leader. On the eve of invasion, bloodshed was prevented when former president Jimmy Carter brokered an agreement with Haiti's leaders in which they pledged to give up power.
(三)Stephen Hawking
Hawking is certainly the most famous physicist in history who has not won the Nobel Prize. This is because the Swedish Royal Academy demands that an award-winning discovery must be supported by verifiable experimental or observational evidence. Hawking's work, to date, remains unproved.
Hawking has made his reputation by investigating, in great detail, one particular set of problems: the singularity and horizons around black holes and at the beginning of time. The idea that the universe had a specific time of origin has been philosophically resisted by some very distinguished scientists.
首先，这些名人都是我们平时很多文章里面可以用来论证的点，其次，这些生平的描写都非常精炼达意。如果我们平时多积累，到需要的时候直接拿出来就比我们自己写要来得更快更准确了。
除了名人之外著名的事例也是很好的例证。比如看下面这个。
American Civil War
The American Civil War erupted when southern states seceded from the Union in order to form their own nation. The North's ultimate victory preserved the Union, abolished slavery, and granted citizenship to newly freed slaves. The Civil War also marked the economic and political ascendancy of the rapidly industrializing states of the North.
