北京市八区2018届初三二模英语分类汇编大阅读Word版含答案

【西城二模】 四?阅读短文,根据短文内容回答问题?(共10分,每小题2分) Mom's Recipe for Life I have a lot of Mom's recipes in a blue box where all my special ones were put,like the pumpkin pie she made during my growing up years. Even so,the recipe I treasure most is not on any index card,nor did she send it to me in a letter. Instead,she lived this recipe all of her life. My mother grew up in a small coal mining town in southwest Iowa. My grandfather once told me that she knew no stranger;she considered everyone in that community her friend. That attitude continued wherever she lived for the rest of her life. As a teen,I was embarrassed(尴尬的)every time my mother talked to strangers and offered a smile to everyone in the store or on the city bus. Almost all of them responded(回应)with a bright smile of their own. Some spoke,others nodded their heads at this elderly woman who brought a little light into their day. What really sold me on Mom's approach to life was her experience on the senior bus. The weeks I could not be there,,I asked her how it went. “ Ha!”she said,“ I got on that bus and what did I see?Thirteen little old ladies and one old man,and not one word was spoken.” I wondered how long it would be until the silence on that bus would change. On my next visit,Mom mentioned the 13 little old ladies on the bus and something one of them had told her. “ Oh,are you talking with them now?”I asked. “ Of course,”she said. “ One day I climbed up the steps of the bus and before I looked for a seat,I gave them a big smile and I said,‘ Isn't it a wonderful day?I noticed a few shy smiles.” Mom didn't give up. She greeted them all each time she got on the bus and before long,the whole group was laughing and talking to one another. The bus became more than just transportation. When we went to the various stores,I watched as she smiled and chatted with perfect strangers. Some of them looked like the poorest person you'd ever met,but once Mom smiled at them and started a conversation,most responded favorably. My mother didn't embarrass me any longer. I found myself admiring her. She's been gone for ten years but I've carried on her recipe for life. It was me who had done the smiling first and all those people had responded. My mother didn't lecture but taught me by example. She'd given me a recipe for life. 34. Where did the writer's mom grow up? 35. Did the people talk on the bus on Mom's first trip? 36. What did Mom do to make the bus more than transportation? 37. How did the writer feel about Mom in the end? 38. What is Mom's recipe for life? 34. In a small coal mining town in southwest Iowa. 35. No,they didn't. 36. She greeted them all each time she got on the bus. 37. Proud. 38. The attitude of considering everyone her friend. 【东城二模】 四、阅读短文,根据短文内容回答问题。(共10分,每小题2分) P. I. C. K. the Right Books for You The secret to learn how to choose the right book is simple. It’s one word you can depend on when you’re in a library or a bookstore. All you need to remember is “ P. I. C. K. “ P. I. C. K. ” stands for Purpose, Interest, Comprehend, and Know the Words. P= Purpose. Why are you looking for a book——reading for pleasure or trying to learn something? Reading silently for yourself or reading out loud for someone else? Most often, your purpose for reading can be found with a quick answer. I = Interest. With the many millions of books on shelves today, there must be something out there for everyone.
