第十篇的问题共10个问题, 这篇多的我都有点不好意思,这一篇做的头大的不得了,做的时候就不太明白这篇文章,请牛牛们多多帮忙了。很是感谢。 1)10行succession是什么意思,是交替的意思吗 2)14-15行trapping sediment over time是什么意思呢? 3)20行flushing 不明白 4)25行mangroves will follow land formation是说mangroves 随着land formation的形成会从地里面长出来吗?land formation是什么意思? 5)16行这句话的意思不太明白 As a habitat gradually becomes more in land as the shore extends,the"land-building"species are replaced. 我觉得这句话是说随着一个居住环境逐渐变成内陆,当海岸扩大的时候,"land-building"被替换了,那么换成什么了呢,这句话的意思不太明白 6)28行-30行这句话不明白什么意思 But on stable coastlines,the distribution of mangrove species results in other patterns of zonation;"land building"does not occur. 7)38行这句话不明白什么意思 thus suggesting that salinity tolerance is a critical factor in competitive success among mangrove species. 8)52题的E选项 (E) establish that plants that do well in saline forest environments require salt to achieve maximum metabolic efficiency E 选项OG解释: Salinity is discussed in the final paragraph but the passage states that salt is not required.The brief discussion of this point shows that it is not the primary concern of the passage. 我的问题:此题E选项OG解释说盐不是必要的,可是在文中说盐能排除低盐的植物,见文中43-46行(Rather, they are metabolically efficient(and hence grow well)in portions of an environment whose high salinity excludes plants adapted to lower salinities.)由此可见盐度高会使mangrove长的更好啊,因为把那些适应低盐的都排除了啊,为什么E选项的OG解释说是不必要的呢? 9)54题D选项和OG解释不太明白 (D)选项: A shoreline extended by"land—building" species of mangroves D的OG解释: If land building has occurred,then the paradigm describing that land building applies. 10)55题对于C为什么对和D 为什么错不明白,对OG给出的解释也很糊涂 (C) Species of plants that thrive in a saline habitat require salt to flourish. (D) Plants with the highest metabolic efficiency in a given habitat tend to exclude other plants from that habitat. OG给出的解释C Correct.This statement contradicts the statement in line 39 about mangroves not requiring salt. OG给出的解释D This general statement agrees with the more specific reference in fines 45;-46 to the metabolic efficiency of mangroves in areas with high salinity;there is no reason to think the author would find it incorrect.
