3 阅读理解。 Technology today has stolen away our voices and robbed our children of memories. I"ve been keeping count of how often people sing around the house these days. The fact is,they don"t. My earliest memories are of my mother crooning lullabies(催眠曲) in a gentle low voice as she rocked each infant in tum. She said she " didn"t have a singing voice," but her low,wavering alto will always mean comfort to me. Every time I have sat through the night with a feverish body or held a pre-schooler through a nightmare,the melodies returned, words appearing and disappearing like fragments of a dream but held together by the hum(低声吟唱) of love. Today,young mothers are routinely presented with lullaby tapes at the baby shower. When baby cries, the idea goes,they will be able to switch on the high-tech audio system and the little one will drift off with the voices of strangers in his ears,perfectly on pitch. If I had my way,new parents would learn the songs themselves,throw out their stereos,and give their child the gift of their own sleepy voices through the midnight hours. These days,when we go on a trip,my daughters take along tiny personal stereos and headphones. They are lost in their private worlds,and I can"t help wishing that at least here,in the car,my girls would be forced to listen to their mother"s voice raised in lost-the-words again,sure I"m out-of-tune songs that they might then pass down to another generation. Those sophisticated earphones have robbed them of something I think every kid should carry from childhood car trips into adulthood. I drove away from that party humming,and all the way home the good old songs kept tumbling out. Dammit(该死) ,I thought,why did I ever stop singing in the car and start tuming on the radio instead? Why don"t I sign anymore while I"m doing the dishes? I"m going to yank those stereo wires right out of the wall when I get home. We"re going to sing grace before meals,sing coals around the piano,sing in the shower instead of switching on that waterproof radio that stole away our voices and our souls. 1. The author hates today"s technology because____. A. driving a car requires high concentration B. children are learning pop songs from tapes C. children have lost touch with good old songs D. high-tech systems do not record the voices of aged people 2.

A. the play of the high-tech system is of little use B. the high-tech system will play on and on C. the low voice will delight the baby D. the baby will slowly go to sleep 3. To the author,the voices of strangers ______. A. are not familiar to the baby B. lack the motherly love the baby need C. work better to stop the baby"s cry D. surely sound more pleasant 4. What the author wishes to make her girls do is to ______ A. help memorize the words while she is singing B. take off their well-designed earphones C. listen and learn the old songs from her D. remember their childhood car trips

9 阅读理解。 Goldie"s Secret She turned up at the doorstep of my house in Comwall. No way could I have sent her away. No way,not me anyway. Maybe someone had kicked her out of their car the night before. "We"re moving house. ""No space for her any more with the baby coming. " "We never really wanted her,but what could we have done? She was a present. " People find all soris of excuses for abandoning an animal. And she was one of the most beautiful dogs I had ever seen. I called her Goldie. If I had known what was going to happen I would have given her a more creative name. She was so unsettled during those first few days. She hardly ate anything and had such an air of sadness about her. There was nothing I could do to make her happy,it seemed. Heaven knows what had happened to her at her previous owner"s. But eventually at the end of the first week she calmed down. Always by my side,whether we were out on one of our long walks or sitting by the fire. That"s why it was such a shock when she pulled away from me one" day when we were out for a walk. We were a long way from home,when she started barking and getting very restless. Eventually I couldn"t hold her any longer and she raced off down the road towards a farmhouse in the distance as fast as she could. By the time I reached the farm I was very tired and upset with Goldie. But when I saw her licking (舔) the four puppies(幼犬) I started to feel sympathy towards them. "We didn"t know what had happened to her," said the woman at the door. "I took her for a walk one day,soon after the puppies were born,and she just disappeared. " "She must have tried to come back to them and got lost," added a boy from behind her. I must admit I do miss Goldie,but I"ve got Nugget now,and she looks just like her mother. And I"ve leamt a good lesson: not to judge people. 1. How did the author feel about Goldie when Coldie came to the house? A. Shocked. B. Sympathetic. C. Annoyed. D. Upset. 2. In her first few days at the author"s house,Goldie _____ A. felt worried B. was angry C. ate a little D. sat by the fire 3. Goldie rushed off to a farmhouse one day because she ______. A. saw her puppies B. heard familiar barking C. wanted to leave the author D. found her way to her old home 4. The passage is organized in order of _____. A. time B. effectiveness C. importance D. complexity
