Passage 19

　　Most people want to work, but it has become m   1        difficult in today's world to find work for e  2   .The economies(经济)of the world n   3       to grow by 4% each year just to keep the old number of jobs for people. Often this is not p    4      and so more people are w    5          work. Some people have no jobs now because new machines can d   6         the work of many people in a shorter time. Also, machines don't ask for more money and l    7      holidays.

About 75000 people are m    9       to the cities a day to look for jobs, but o    10      70% of them can find jobs.

　　Passage 20

　　Someone says, "Time is money," but I think time is even more i  1    than money. Why? Because when money is s  2   we can get it b  3    . However, when time is g   4    it'll never return.
