若关于x的方程3(x+4)=2a+5的解大于关于x的方程 的解,试确定a的取值范围. 答案:解:∵3(x+4)=2a+5,∴x= 2a−73 ,∵ (4a+1)x4=a(3x−4)3 ,∴x=﹣ 163 a,∴ 2a−73 >﹣ 163 a,解得a> 7181、An elderly carpenter was ready
to retire.He told his employer of his
36 to leave the house-building business to 37
a happier life with his wife and enjoy his extended family.He would 38 the salary each week,but he wanted to 39 .They
could get by.The employer was 40 to
see his good worker go and asked if he could build just one more house as a
personal 41 .Thinking for a moment,the carpenter said yes,but 42
his heart was not in his work.He used some
materials with poor quality and 43 it with poor workmanship.It was a (n)
44 way to end a devoted career.When the carpenter finished his work,his
employer came to 45 the house.Then
he handed the front-door key to the 46 and said,“This is your house… my 47 to
you.”When the carpenter heard these words,he was 48 ! What a shame! People all could not
help saying: 49 he had known he was building his own house!
So it is with us.We 50 our lives,reacting rather than acting,often
51 less energy and time to the building.Then,with a shock,we 52 we
have to live in the house we have built.If we could do
it again,we would do it 53 .
Someone once said,“Life is a do-it-yourself
54 .”Your attitude and the choices you make
today help build the “house”
you will live in tomorrow. 55 ,build wisely!
