At four o'clock     1     a foggy day, Polly left work and stepped out into the fog, wondering if the buses would still be     2     (run). She walked     3     (quick) towards her usual bus stop, only to be told the bus couldn’t run to King Street that day. She     4     (have) to take the underground to Green Park, where there was no one in sight. As she walked along the narrow street, Polly heard     5     same sound of footsteps approaching,     6     then the footsteps were gone. Suddenly Polly was     7     (frighten) by a man’s rough hand brushing her cheek. He said sorry to her and moved away. Then the     8     (footstep) were heard again. Polly was more frightened than a minute before, and she couldn’t move at all.

Luckily for Polly, it was a blind man     9     wanted to offer help. With the blind man’s help, Polly got to     10     (she) living place, King Street.

In La Paz there are many roads     1     bad condition. One road in particular,     2     goes north from La Paz,     3     (consider) the most dangerous road in the world. On one side the mountains rise     4     (steep); on     5     other side there is a sheer drop. On average, one vehicle comes off the road every two weeks. The drop is so great     6    anyone inside the vehicle is lucky to survive.

Thanks to Timoteo Apaza, the death toll     7     (fall). Every morning he climbs up to the bend to direct the traffic, working as a volunteer. Before that, he     8     (have) lots of jobs. How much do you think Timoteo receives from doing it? Nearly nothing. Sometimes drivers give him a tip which is just enough for him     9     (live) on. But often they just pass by,     10     (take) the human traffic signal for granted. The reason why he does it is that he feels it is his mission in life to help others.
