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
A. they wanted to attack Washington at Trenton
B. they had no boats in which to cross the Delaware River
C. they need time to make some preparations
D. they wanted Washington to think they had given up rights

Passage One
There was a nasty (肮脏的，卑鄙的) accident in our town not long ago, and I saw it happen. I was standing near a road which was under repair, not doing anything special--just watching the men at work. It was not far from the new motorway (高速公路) that runs past the town. It was an old road that used to be very busy--and dangerous--before the motorway was built. Today, most cars use the new "superhighway" and the old road is pretty quiet, although cars do often come off the motorway into the town faster than they should.
Anyway, the men were repairing part of the road and there were signs up for at least 200 meters, telling everybody that the road was narrower than .usual. Most of the drivers in both directions saw the signs and slowed down.
Then three cars came along close’ together, the third one moving at a very high speed. ’The first one passed the workmen and wanted to turn left. Meanwhile the third car came flying past
A. was very busy though there was a new motorway
B. was never very busy
C. was always very busy and dangerous
D. was very busy and dangerous before the construction of the new motorway
