最新高中英语必修三测试题全套及答案 (人教新课标) Unit 1 单元测试题 阅读理解(共两节,满分40分) 第一节(共15小题;每小题2分,满分30分) 阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。 A Walk into the California home of Anne Belles and her husband, Jim Silcock, and you?ll see kids everywhere playing video games, doing homework, and getting ready for dinner. There are 30 boys in this house and Anne Belles is their mom. Belles has wanted to help children since she was a kid. “I was intrigued by the movie Oliver! in the 1960s, a musical based on the Charles Dickens novel Oliver Twist. I told my mom, …That?s what I want to do. …” Anne?s boys are from 3 to 25 years old. All of them are challenged in some way. “They each have special needs — physically, mentally (精神上), or at school,” says Belles. Every day, a small army of childcare workers, nurses, and volunteers comes in to help cook and clean, wash 30 loads of laundry a day, and take care of health needs. To find out how much such a large family costs, we followed Jim Silcock to the grocery store. He spent $880 on food for one week. Every month they spend $2,000 to run five cars, $15,000 for the fourteen paid helpers, and more than $10,000 on medical costs. The family receives $26,000 a month from the state government, and makes some money from a family business. All the money is spent on the children; having new clothes and fancy cars isn?t important to Belles. How do the kids feel? 17-year-old Anthony says, “The family is there whenever I need something ... I feel like I am loved.” “Everything I?m doing now is what I wanted to happen in my life,” says Anne Belles. “So, no regrets; this is perfect. I couldn?t ask for it to be better — maybe a bigger house, you know, would be nice.” 21. The underlined word “intrigued” in the first paragraph means “_____”. A. fooled B. attracted C. frightened D. disappointed 22. The boys Anne has raised _____. A. are all ready to accept a challenge B. all like Oliver Twist C. all have disabilities

Mother hands me the grocery list and puts money in my pocket, hoping it will be enough. She's had a hard day, and I've had a hard week. Nothing out of the ordinary happens when I get to the store. I grab the bread, some milk, and other things on the list. As I turn to head out, I see a beautiful dress in the window. I turn away, bitter that I could never own such a dress. Outside, I cannot stop thinking about that pretty dress. It's not fair that I can never have what I want. I work so hard to help my family and yet I get nothing in return, just another list to do. In my anger, I fail to realize the apples are rolling across the road. Suddenly, I see a pair of hands, offering me an apple. Looking up, I see the tanned (晒黑的) face of this stranger. His clothes are mismatched, borrowed or stolen. But his eyes are soft and kind. “Thanks,” I say. No other words are spok en as he continues to help me. I tell him “thank you” one more time and am on my way because I have many other things to finish. Suddenly, he says, “Have a good day, ma'am.” And then he gives me the biggest smile I have ever seen. Right then, he looks years younger — and I feel a fool.
