days to go from England to India by train and by ship. A letter can get to India by air in five days now, but

plane may fall and their friends may not receive the letters. So they sent two letters, one by air and the other
by train or ship. They wanted to make sure that the letter would be received. Planes are now almost as safe
and sure as trains or ships. More and more letters are sent by air.

Strange, but the green sea turtle (小海龟) is not that green. It"s certainly not as green as a tree. In fact,
its shell (壳) is nearly black or brown. The largest hard-shelled sea turtle is between 200 and 300 pounds
heavy and a shell is between 36 and 43 inches (英寸) long. But its head is smaller than other turtles.
Little baby green sea turtles are only two inches long. As the turtle grows up, its shell keeps mostly
black while the body turns orange or brown. Young turtles like living in the sea, especially in areas with lots
of sea grasses.
Green sea turtle, like all sea turtles, are very different from land or river turtles. All sea turtles can swim
through the water faster. Instead of feet for walking, sea turtles have flippers (鳍状肢) which are better for
swimming. The flippers aren"t much good on land, however, and walking is hard for a sea turtle because
they are usually big and heavy.
Another interesting thing about a sea turtle"s flippers is that they cannot be pulled into their shells. Land
turtles can pull their feet into their shells for protection, but a sea turtle can"t.
