22、ou ever wondered-can plants think?（这是整篇文章作者想要解决的问题）On land, the cumulative mass of plants is 1000 times higher than that of animals. But these plants are immobile and cant move around in their environment; which is, seemingly, a pretty big evolutionary disadvantage. This has forced plants to adapt i
23、n amazing ways that often go unnoticed by the naked eye.Smell something funny? Plants do too-and they react to these chemicals in the air. For example, when fruits start to ripen, they release a chemical called ethylene. And when neighboring fruits sense this pheromone, they ripen faster, so that al
24、l fruits mature at the same time. Plants also give off scents which attract insects to spread their pollen.

30、se leafy plants that close up when touched. This reflex is meant to scare away insects that land on them. In an experiment on these reflexes, scientists notice that when dropped from 15cm， they would close when they hit the ground, Not so surprising. But after repeating the drop 4 or 5 times, some o
31、f the plants stopped closing， as though they had realized the stimulus wasnt harmful. If they were shaken instead, they would close, but any time they were dropped from this same height, they stayed open.

A summary has two aims: (1) to reproduce the overarching
44、ideas in a text, identifying the general concepts that run through the entire piece.(2) to express these overarching ideas using precise, specific language. When you summarize, you cannot rely on the language the author has used to develop his or her points, and you must find a way to give an overvi
45、ew of these points without your own sentences becoming too general. You must also make decisions about which concepts to leave in and which to omit, taking into consideration your purposes in summarizing and also your view of what is important in this text. Here are some methods for summarizing: Fir
46、st, prior to skimming, use some of the previewing techniques.1. Include the title and identify the author in your first sentence.2. The first sentence or two of your summary should contain the authors thesis, or central concept, stated in your own words. This is the idea that runs through the entire
47、 text-the one youd mention if someone asked you: “What is this piece/article about?” Unlike student essays, the main idea in a primary document or an academic article may not be stated in one location at the beginning. Instead, it may be gradually developed throughout the piece or it may become full
48、y apparent only at the end.3. When summarizing a longer article, try to see how the various stages in the explanation or argument are built up in groups of related paragraphs. Divide the article into sections if it isnt done in the published form. Then, write a sentence or two to cover the key ideas
49、 in each section.4. Omit ideas that are not really central to the text. Dont feel that you must reproduce the authors exact progression of thought. (On the other hand, be careful not to misrepresent ideas by omitting important aspects of the authors discussion).5. In general, omit minor details and specific examples. (In some texts, an extended example may be a key part of the argument, so you would want to mention it).6. Avoid writing opinions or personal responses in your summaries (save these for active reading response
