change is good.Without change our lives would be very boring indeed.It would
be like 37 the same song on you iPod over and over and over again.
Some
people,of course,don’t like change.They want life to be predictable (可预言的).
They want to do 38 same things every day and 39 the same people
every day.When something changes; it makes 40 feel insecure (不安全的) and
uncomfortable.Like a child 41 can’t go to sleep unless all his toys are
in the proper places.
But change is big part of life and we all change in
small ways every day:the young get stronger,the 42 get weaker; we meet new
friends; we 43 new interests.
You will probably go 44 many
changes in your lifetime.In America,people can expect 45 jobs an average
(平均数) ten times during their lives.They can expect to change their homes eleven
times.That’s a lot of change!But people in America like change 46 they
think it improves their lives.
China has seen many changes 47
