[单项选择] Memory Class
Stan Field knows what age can do to a person’’s memory, and he’’s not taking any chances with his. He chooses his food carefully and gets plenty of exercise. He also avoids stress, coca cola and cigarette smoke.

And when she got there, she found herself surrounded by people who were just as worried as she was.

[单项选择]Have you ever heard of a flower whose seeds are carried and spread by elephants The rafflesia, a rare blossom, is very unusual. Found in the rain forests of Sumatra, the rafflesia is the world’s largest flower, measuring three feet in diameter!
This giant flower is a parasite--it needs another plant to live on. It lacks the structures needed to survive alone. The rafflesia has no stem or leaves. It is all flower. It attaches itself to the roots of other plants and sucks their juices. The flower’s favorite home is the root of the vine, which grows above ground.
The rafflesia seems to burst right out of the forest floor. Its blossom weighs fifteen pounds! It has thick, spotted petals that give off a rotten smell. The center is about the size of a household bucket. After a rain, it may hold up to twelve pints of water!
After the rafflesia dies, it becomes a pool of thick liquid in which its seeds float. Elephants wandering through the forest step into the mushy pool,

Expensive luxuries will give place to more necessary articles, rare wines to meat and bread, new machines and factories to clothes and improved small dwellings; and there will be other changes of a like sort. In view of this fact, it is inexact to speak of a change in the distribution of the dividend in favor of, or adverse to, the poor.

In fact, there is no such thing as the dividend from the point of view of both of two years, and therefore, there can be no such thing as a change in its distribution.
