And the twins, Alisa and Alan. And then Helen. Five children. I was too busy raising them to grow a garden.Money was tight, as well as time. Often when my children were little, one of them would want something that cost too much, and I’d have to say, “Do you see a money tree outside？Money doesn't grow on trees, you know.”Finally, all five got through high school and college and were off on their own. I started thinking again about having a garden.I wasn’t sure, though. I mean, gardens do cost money, and after all these years I was used to living on a pretty lean, no-frills budget.Then, one spring mor ning, on Mother’s Day, I was working in my kitchen. Suddenly, I realized that cars were tooting their horns as they drove by. I looked out of the window and there was a new tree, planted right in my yard. I thought it must be a weeping willow, because I saw things blowing around on all its branches. Then I put my glasses on—and I couldn’t believe what I saw. There was a money tree in my yard!I went outside to look. It was true！There were dollar bills, one hundred of them, taped all over that tree. Think of all the garden flowers I could buy with one hundred dollars! There was also a note attached: “IOU eight hours of digging time. Love, Marvin.”Marvin kept his promise, too. He dug up a nice ten-by-fifteen foot bed for me. And my other children bought me tools, ornaments, a trellis(棚架), a sunflower stepping stone and gardening books.That was three years ago. My garden’s now very pretty, just like I wanted. When I go out and weed or tend my flowers, I don’t seem to miss my children as much as I once did. It feels like they are right there with me.I live up in Michigan’s Upper Peninsula, where winters are long and cold, and summers are too short. But every year now, when winter sets in, I look out of my window and think of the flowers I’ll see next spring i n my little garden. I think about what my children did for me, and I get tears in my eyes every time.I’m still not sure that money grows on trees. But I know love does!1. By saying “Do you see a money tree outside…”the mother actually means “________”.A. Observation is the best teacherB. Seeing is believingC. The outsider sees the most of the gameD. It is not easy to gain money2. The best title for the passage would probably be ________.A. My flower gardenB. Marvin helps to realize my dreamC. Love in MichiganD. Money grows on trees3. The underlined word “no-frills” in the fifth paragraph is similar in meaning to ________.A. wastefulB. tightC. absurdD. helpful4. From the last three paragraphs we can infer that the mother is________.A. divorced when she was youngB. not caring for her kids any longerC. alone but not at all lonelyD. prouder with her garden than with her kids六、书面表达假定你是中学生李华。

长难句的化解 阅读理解难点在长难句上,所谓长难句就是众多语法结构按照一定 的语法顺序堆砌起来,使同学们看见就晕眩。一个英语句子之所以 难以理解有许多原因,其中一个主要原因是句子太长或者句子结构 复杂。句子过长或者复杂无非是该句除了主干之外还包含了一些 附加部分,如插入语、同位语、分隔现象、各种从句或较长的非谓 语动词短语等等。这些附属成分常由逗号或分隔符号与句子隔开, 且插在一个句子中间,使本来完整的句子被断开,因而增加句意理 解的难度。 分析长难句的基本方法是:首先,判断该句是简单句、并列句还是 复合句;然后,找出句子的核心成分,分清主语和谓语,再分清句子附 属成分。下面我们来谈谈几种长难句的处理技巧。
