(根據短文內容回答下列問題)

Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him --until 1970. In that year a Canadian scientist George Kell proved(證明) the English professor (教授) was right. Dr Kell filled an open oil pail (桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapour (蒸汽). This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make.

(1)

What did Sir Francis Bacon find several hundred years ago?

(2)

When did people believe what Sir Francis Bacon said?

(3)

Who proved what Sir Francis Bacon said?

(4)

What will you find if you leave a pail with warm water and another pail with cold water in the same low temperature?

(5)

Why does warm water freeze first in the same freezing weather?

In today’s world many people seem to be hungry for money. Money does have its most useful effect on the poor. But even if a person has already got plenty of money, he can’t get everything.

If money were everything, all millionaires would have real love, true friendship, good health and a long life. However, this is not always correct.

Since the beginning of time no three words have ever invited more pleasure than “I love you”. But can love be bought? I’m afraid not. Love means to give, not ________ (78). To every person, health and a long life are probably the best things. Well, can health and a long life be bought with money? The answer is “No”.

(79) Of all the longest living people in the world, few of them are millionaires. True friendship can’t be bought, either. In a word, where money is dreamed too much, it can cause brothers to quarrel, marriage to end, lovers to hate, and strangers to fight. No matter how much money you have, it is still not enough to make a happy person if you have no one to laugh with, no one to cry for.

根據短文內容，完成下列各題。

1.從文中找出與下句意思相近的句子。

It seems that a lot of people want money very much now.
