Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since they, the plants, are the only form of life that is able to get and store energy.
The first plants to exist out of the water were probably certain kinds of algae(海藻)which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution(进化)took place quickly. By the end of 100 million years, plants had developed their roots(根),and some had got tree-like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.

Strangely enough, they said hardly anything about it at all. There were only a few reports about it in the papers. These reports said very little. Some of the things they said were not even correct.
In 1904 the Wrights built a second machine. They called it "Flyer No. Two". They invited some reporters to a field near Dayton to watch them fly. Unfortunately there was some mechanical (机械的)trouble with the plane and it did not fly at all that day. The newspapermen went away. They were disappointed and did not come back. The Wrights went on with their work. In 1905, they built an even better machine, "Flyer No. Three". They were able to stay upon the air for half an hour and more in the machine and they were able to turn and climb in the air. Farmers and travelers on the road around Dayton often saw them flying. But when these people told newspapermen about it, they refused to believe them.
The Wrights offered "Flyer No. Three" to the United States govern ment. The government was not interested. They seemed to think the Wrights wanted money in order to build a plane. They did not understand the Wrights had already done this, and flown it as well. Experts were still saying that mechanical flight was impossible. At the end of 1905, the two brothers took their plane to pieces. The parts were put into a huge wooden box. It seemed nobody was interested.

B. they saw the Wrights failed to fly "Flyer No. Two"
C. they had never seen a machine that can fly
D. all the above
3.The U. S. government could not understand that __________
A. the Wrights had already built a machine that could fly
B. experts still thought flight was impossible
C. the Wrights wanted more money to build an airplane
D. "Flyer No. Three" was then in a woken case
