11．My friend Vernon Davies kept birds．One day he phoned and told me he was going away for a week．He asked me to feed （16）the birds for him and said that he would leave the key （17）to
his front door in my mailbox．
（18）Unfortunately（fortunate），I forgot all about the birds until the night before Vernon was going to return．What was worse，（19）it was already dark when I arrived at his house．I soon found that the key Vernon gave me could not unlock either the front door （20）or the back door．I was getting desperate．I kept thinking of （21）what Vernon would say when he came back．
I was just going to give up （22）when I noticed that one bedroom window was slightly open．I found a barrel and pushed in under the window．As the barrel was very heavy，I made a lot of noise．But in the end，I managed to climb （23）up and open the window．
I actually had one leg inside the bedroom when I suddenly realized that someone （24）was shining
（shine） a torch up at me．I looked down and saw a policeman and an old lady，one of Vernon's neighbours．"What are you doing up there？"said the policeman． （25）Feeling（feel） like a complete fool，I replied，"I was just going to feed Mr Davies'birds．"

10．During an 1899F4tornado （龍卷風(fēng)） in Missouri，three people，Miss Moorehouse，Mrs．Webster，and her son were caught up in the storm．They （16）werecarried （carry） nearly one mile，but were let down so gently （17）that none of the three was seriously injured．Here is Moorehouse's （18）description （describe）of her unbelievable flight．
‘‘I was conscious all the time when I was flying through the air，and （19）it seemed a long time．I seemed to be lifted up，（20）going （go） up to a great height．At one time I was far above the church towers，and seemed to be carried to a （21）distant （distance） place．As I was going through the air，I saw a horse，（22）which was a white one and had a harness （馬具） on，floating about with me．By the way （23）the horse kicked and struggled as it was thrown about，I knew it was alive．I was afraid that it would knock into me，（24）but it did not．Finally，I was mercifully landed （25）upon/on the ground unharmed，saved by luck．"

9．I was feeling sad because my mother was out of job．It left me wondering （16）what was going to happen to us．
I got off the college shuttle bus and started walking．Then I heard piano music and singing rising above the noise of the people and the traffic．I walked much （17）slower （slow） so I could find out where it was coming （18）from．Through the crowd I saw a young lady sitting at a piano with a carriage next to her．She was singing songs （19）about  love and keeping on trying，and not underestimating（低估） the power within yourself．The way she was singing comforted me a bit．I stood there （20）watching（watch） her play for about fifteen minutes，thinking that （21）it must take courage to perform on her own in the middle of a crowd．
She must have felt my presence because she would occasionally look in my direction．By now I was telling （22）myselfthat if she could perform in front of hundreds of people （23）that/who/whomshe didn't know，I could at least tell her how good she sounded．I walked over，（24）put （put） some money in her carriage and said，"Thank you．I have been going through a rough time lately，but you've made me （25）hopeful（hope） again．"

8．As we all know，games play a very important role in the growth of children．Children should grow along with playing games，for（16）through playing games，they can not only acquire knowledge，but also cultivate their abilities to get along with others．
    However，most children （17）are faced（face）with a completely different situation．Most parents fear that games will prevent children from increasing new knowledge and  （18）thatthe children will fail in the future examinations．So，instead of （19）letting（ let ） the children （20）themselvesfind and learn naturally from their surroundings，they force their children to take part in various kinds of classes，learning English，playing （21）the piano or practicing drawing，etc．What's more，some parents put  （22）awaythe children's toys which are very useful in developing children's imagination and practical abilities．
  （23）Hereis a piece of good advice to those parents：（24）if/whenyou want to expect your child to be able to accomplish something，you must first of all develop his ability to adapt to the new surroundings．That cram education can lead to nothing （25）but a failure in the children's growth．
