4 阅读理解。 We have two daughters: Kristen is seven years old and Kelly is four. Last Sunday evening, we invited some people home for dinner. I dressed them nicely for the party, and told them that their job was to join Mommy in answering the door when the bell rang. Mommy would introduce them to the guests, and then they would take the guests"coats upstairs and put them on the bed in the second bedroom. The guests arrived. I introduced my two daughters to each of them. The adults were nice and kind and said how lucky we were to have such good kids. Each of the guests made a particular fuss over Kelly, the younger one, admiring her dress, her hair and her smile. They said she was a remarkable girl to be carrying coats upstairs at her age. I thought to myself that we adults usually make a big "to do" over the younger one because she"s the one who seems more easily hurt. We do it with the best of intentions. But we seldom think of how it might affect the other child. I was a little worried that Kristen would feel she was being outshined. I was about to serve dinner when I realized that she had been missing for twenty minutes. I ran upstairs and found her in the bedroom, crying. I said, "What are you doing, my dear?" She turned to me with a sad expression and said,"Mommy, why don"t people like me the way they like my sister? Is it because I"m not pretty? Is that why they don"t say nice things about me as much?" I tried to explain to her, kissing and hugging her to make her feel better. Now, whenever I visit a friend"s home, I make it a point to speak to the elder child first. 1. What did the parents ask the sisters to do to welcome the guests? A. To introduce themselves to the guests B. To put away the guests" coats in another upstairs room. C. To take off the guests" coats politely. D. To entertain the guests with candies. 2. The underlined expression" make a big "to do" over" (paragraph 4) means ______. A. show much concern about B. have a special effect on C. list jobs to be done for D. do good things for 3. The guests praised Kelly for carrying coats upstairs because of her ______. A. beautiful hair B. pretty clothes C. lovely smile D. young age 4. Kristen felt sad and cried because ______. A. the guest gave her more coats to carry B. she didn"t look as pretty as Kelly C. the guests praised her sister more than her D. her mother didn"t introduce her to the guests 5. We can conclude from the passage that ______. A. parents should pay more attention to the elder children B. the younger children are usually more easily hurt C. people usually like the younger children more D. adults should treat children equally
