易错题解析：
Paragraph 4:The terrestrial world is green now, but it did not start out that way. When plants first made the transition ashore more than 400 million years ago, the land was barren and desolate, inhospitable to life. From a plant’s evolutionary view point, however, it was also a land of opportunity, free of competitors and predators and full of carbon dioxide and sunlight (the raw materials for photosynthesis, which are present in far higher concentrations in air than in water).So once natural selection had shaped the adaptations that helped plants overcome the obstacles to terrestrial living, plants prospered and diversified.
6. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
○ Terrestrial plants had the advantages of not having rivals and having easy access to photosynthetic material
○ The abundance of photosynthetic material made life on land easier for pioneering plants
○ Once plants had eliminated their competitors and their predators, their evolutionary process proceeded smoothly.
○ Plant evolution eliminated competitors and made the process of photosynthesis more efficient.
题型：句子简化题。答案是(A)
解析：原句主干说是一片充满机遇的陆地，没有 competitor，没有predator，有阳光和二氧化碳。所以正确答案是A。B选项说 photosynthetic material 丰富是对的，但easier life on land原文没讲，不选;C和D的eliminate competitors原文没讲，原文说没有competitor，而不是被 eliminate掉了。
Paragraph 3:█The environmental conditions of freshwater habitats, unlike those of ocean habitats, are highly variable. █Water temperature can fluctuate seasonally or even daily and changing level of rainfall can lead to fluctuations in the concentration of chemical in the water or even to period in which the aquatic habitat dries up. █Ancient fresh water green algae must have evolved features that enable them to withstand extremes of temperature and periods of dryness. █These adaptations served their descendant well asthey invaded land.
13. Look at the four squares [█] that indicate where the following sentence could be added to the passage.
Scientists believe that chemical changes and a thicker exterior, among other things, may have helped ancient algae overcome the conditions in their environment.
Where would the sentence best fit? Click on a square to add the sentence to the passage.
题型：句子插入题。答案是(D)
解析：以 ancient algae 做过渡点，找到原文倒数第二句，所以答案非C即D。倒数第二句说有feature 使它们忍受和极端温度干旱，而待插入句讲这些都是什么样的特点，也刚好与后面的these adaption 形成很顺的过渡，正确答案是D。此外，待插入句中的among other things也是一个很好的点。
