单选题Thomas Jefferson was the first President to take office in the new capital, Washington D. C. Although Washington was a new city, it was already familiar to president Jefferson. In fact, Jefferson had helped plan the capital' s streets and public buildings. Besides being a city planner, the new President was a writer, a scientist, and the inventor of several tools. Jefferson moved into the Presidential Palace after he took office. The Palace was more than a home, it had offices for the President and some other men of the government. It also had dining and reception rooms, where the President could receive his guests. However, president Jefferson did not give many formal parties. This was partly be cause there was no First Lady; his wife died in 1782. It was also be cause Jefferson liked to live in a simple way. He once showed up for an important meeting wearing old clothes and worn slippers! Neither Washington nor Adams would ever have dressed like that. Jefferson was different from the first two Presidents in other ways, too. He didn't agree with them about how the country should be run, and about what part a President should play in running it.

单选题Trees have a spectacular survival record. Over a period of more than 400 million years, they have evolved as the tallest, most massive, and longest-lived organisms ever to inhabit the Earth. Yet trees lack a means of defense that almost every animal has: trees cannot move away from destructive forces. Because they cannot move, all types of living and nonliving enemies—fire, storms, microorganisms, insects, other animals and, later, humans—have wounded them throughout their history. Trees have survived, because their evolution has made them into highly compartmented organisms. In that respect trees are radically different from animals. Fundamentally, animals heal: they preserve their life by making billions of repairs, installing new cells or rejuvenated cells in the positions of old ones. Trees cannot heal: they make no repairs. Instead, they defend themselves from the consequences of injury and infection by walling off the damage. At the same time they put new cells in new positions; in effect, they grow a new tree over the old one every year. The most obvious results of the process are growth rings, which are visible on the cross section of a trunk, a root, to a branch.

I thought she was {{U}}winding me up{{/U}} when she phoned me from Australia. " he said. Johnstone then asked Dolby to marry him on the phone. "I didn't know whether to laugh or cry, but I accepted.
