A.deal B.dealt C.to deal D.dealing 解析:选C。该句为“have something to do”结构,动词不定式短语作定语。 句型梳理 1【教材原句】 As time went by,I was made smaller.(P18) 随着时间的流逝,我被做得更小了。 【句法分析】 as意为“随着”,引导时间状语从句。 ①As we grow older,we get wiser. 随着年龄的增长,我们会变得越来越聪明。 ②As time went on,Einstein’s theory proved to be correct. 随着岁月的推移,爱因斯坦的理论被证明是正确的。 [易混辨析] as,with (1)as是连词,引导时间状语从句。 (2)with是介词,后接名词或代词构成with短语或with复合结构。 ①As our life improves,we find more and more time entertaining. ②With the time going by,they became close friends.

A.going on B.goes on C.went on D.to go on 解析:选A。with复合结构在句子中作伴随状语。“with+n.+doing/done/介词短语”为固定结构。noise与go on之间为主动关系,故选A。 2【教材原句】 And my memory became so large that even I couldn’t believe it!(P18) 我的存储量变得如此之大,连我自己都不能相信! 【句法分析】 so/such...that引导结果状语从句,意为“如此……以至于”。 so...that...的基本句式: (1)so+形容词(副词或分词)+that从句 ①She was so excited that she couldn’t go to sleep. 她兴奋得睡不着觉。 ②There are so many people in the street that I can’t get through. 街上有这么多人我过不去。 ③There was so little water left that only little children were given some.剩下的水不多了,只给小孩分了一些。 [归纳拓展] ④It was such fine weather that we had a picnic together. 天气那么好我们一起去野餐了。 ⑤It was such a lovely day that we decided to go outing. →It was so lovely a day that we decided to go outing. 天气那么好,我们决定去郊游。 (2)当so.../such...放在句首时,主句要用部分倒装。 ⑥So fast did the teacher speak that I couldn’t follow him.

The son and the dad were on their way to their tree stands when the son saw a bobcat (美洲野猫). They saw it standing up on its hind legs looking for something to eat. The dad told his son to try to walk slowly around the bobcat but they stepped on a branch when they saw the bobcat. When they stepped on the branch the bobcat saw them and started to charge(猛冲) after them. The bobcat took down the dad, so the son ran as fast as he could to get to his tree stand. The son grabbed his deer rifle, put a bullet in it, looked at the bobcat, and shot it in the heart. The son got out of his tree stand to go check on his dad. When he got over to his dad he removed the dead bobcat. Then he called the EMT's (急诊医士) because he thought his dad was really hurt from when the bobcat stomped on him and bit him. The EMT's told the son they were 10 minutes out. Before the EMT's got there the son took his dad into the hunting shack to clean out his cuts. After the EMT's arrived at the deer shack they looked at the son's dad. They said he will be in the hospital for 10 days. He had ten broken ribs and 5 broken neck bones, so after the son heard this he started crying. The EMT's said, "We can take you to your grandma's house." The ten days were up now so the son went back to the hospital and the doctors explained that his dad would be paralyzed(瘫痪) from the waste down. Then the son asked the doctors, "Can we could still go hunting and fishing together." They replied no, but you and your grandma can do those things together.

C I am often asked how I started Pajama(睡衣) Program but honestly, I feel like Pajama Program happened to me, not the other way around. I never set out to start a non-profit, nor did I have a desire to turn my life upside down. All I asked for was a little "purpose" to my life. And you know what they say, be careful what you ask for... I visited a safe house for abused and abandoned children. My intention was to read with the children in the evening, once a week after my work day. I loved my marketing job and planned to continue advancing my career for many years to come. One night as I said goodbye to the children I watched them go into a nearby room to sleep. They slowly climbed onto couches and futons. Some were crying and the staff tried to comfort them and ease them onto a soft surface. There was no changing of their clothes, no bedtime stories, no hugs from moms or dads. I was puzzled. This was not the way bedtime was supposed to be for a child. I waited for the staff to finish with the children and asked them if they needed pajamas... could I bring some? The next week I brought 12 pairs of pajamas with me—one for each child I was told would be there. As the children came into the room to sit and read with me, I gave each one a pair of pajamas. One little girl wouldn't take pajamas from me. She stood perfectly still, looked up at me, and asked in a whisper, "What are these?" "They're pajamas," I said. "Where do I wear them?" I answered her, "To bed at night." She looked at me, puzzled. "What do you usually wear to bed?" I asked her. "My pants," she said quietly. My heart sank. It was at that moment I knew I had found my true purpose in life. I told everyone to give me new pajamas... for my birthday, anniversary... Christmas... and I gave them to the children. How incredible when my friends came with me! I knew what was happening; I was feeling a new swell in my heart... for these children who needed pajamas and a book for bedtime. 10. According to the passage, the author started Pajama Program . A. by chance B. to turn her life upside down C. as a non-profit project D. by choice 11.
