During the second half of 1776, the British had driven Washington's armies from their strongholds in and near New York City. Washington retreated, moving southeast across New Jersey.
Before his army reached the shores of the Delaware, he sent soldiers ahead to bring together all the boats they could find. When the British arrived at the east bank early in December, the Colonials were safely across. And the British could find only two small boats on a pond.
For the time being, the British gave up the chase. They set up camp at Trenton and at other strongholds along the Delaware.
Washington had the boats on the Pennsylvania side, but that was about all he had. Food was short, and many soldiers were too iii to march. And any day now, the river might freeze, making it possible for the British force to cross into Pennsylvania.
If the struggle for freedom was to continue, Washington had to have a victory. Finally he decided to re-cross the Delaware at Mckonkey's Ferry. That was nine miles up river from Trenton. Washington's plan was to cross under cover of darkness on Christmas night and attack the 2,000 to 3,000 British soldiers in Trenton. The general expected that the enemy force would still be celebrating the holiday. On the evening of December 25, Washington gave the orders to cross. It was sleeting snowing, and the river was filled with floating ice. Finally, his force of more than 2,000 men was on the Jersey side. It was after 2 a.m.. In a battle that lasted less than two hours, they defeated the enemy force. Washington had the victory he needed.
This story is about______.
A.the battle for human rights and progress
B.the battle of Delaware River
C.the American Civil War
D.the American War of Independence

Some of the notebooks George Washington kept as a young man are still in existence. They show that he was learning Latin, was very interested in the basics of good behaviour in society, and was reading English literature.
At school he seems only to have been interested in mathematics. In fact his formal education was surprisingly brief for a gentleman, and incomplete. For unlike other young Virginian gentlemen of that day, he did not go to the College of William and Mary in the Virginian capital of Williamsburg. In terms of formal training then, Washington contrasts sharply with some other early American Presidents such as John Adams, Thomas Jefferson and James Madison. In later years, Washington probably regretted his lack of intellectual training. He never felt comfortable in a debate in Congress, or on any subject that had not to do with everyday, practical matters. And because he never learned French and could not speak directly to the French leaders, he did not visit the country he admired so much. Thus, unlike Jefferson and Adams, he never reached Europe.
What reason does the author give for Washington not going to college?
A.His family could not afford it.
B.A college education was rather uncommon in his times.
C.He didn't like the young Virginian gentlemen who went to college.
D.The author doesn't give any reason.

Psychologist George Spilich and colleagues at Washington College in Chestertown, Maryland, decided to find out Whether, as many smokers say, smoking helps them to "think and concentrate." Spilich put young non-smokers, active smokers and smokers deprived (被剥夺) of cigarettes through a series of tests.
In the first test, each subject (试验对象) sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96. In this simple test, smokers, deprived smokers and nonsmokers performed equally well.
The next test was more complex, requiring all to scan sequences of 20 identical letters and respond the instant one of the letters was transformed into a different one. Non-smokers were faster, but under the stimulation of nicotine (尼古丁), active smokers were faster than deprived smokers.
In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers.
The fourth test required people to read a passage, then answer questions about it. Non-smokers remembered 19 percent more of the most important information than active smokers, and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also had trouble separating important information from insignificant details.
"As our tests became more complex," sums up Spilich, "non-smokers performed better than smokers by wider and wider margins." He predicts, "smokers might perform. adequately at many jobs until they got complicated. A smoking airline pilot could fly adequately if no problems arose, but if something went wrong, smoking might damage his mental capacity."
The purpose of George Spilich's experiment is ______.
A.to test whether smoking has a positive effect on the mental capacity of smokers
B.to show how smoking damages people's mental capacity
C.to prove that smoking affects people's regular performance
D.to find out whether smoking helps people's short-term memory
