Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

1、互逆命題：在兩個命題中，如果第一個命題的條件是第二個命題的 ，而第一個命題的結(jié)論是第二個命題的 ，那么這兩個命題互逆命題，如果把其中一個命題叫做原命題，那么另一個命題叫做它的 .2、互逆定理：如果一個定理的逆命題也是 ，那么這個逆命題就是原來定理的逆定理.注意(1)：逆命題、互逆命題不一定是真命題，但逆定理、互逆定理，一定是真命題.(2)：不是所有的定理都有逆定理.自主學(xué)習(xí)診斷：如圖所示：(1)若∠A= ，則AC∥ED，( ).(2)若∠EDB= ，則AC∥ED，( ).(3)若∠A+ =1800，則AB∥FD，( ).(4)若∠A+ =1800，則AC∥ED，( ).
