　　TPO5-1 Mineralsand Plants 【TPO5-1原文及答案】

　　植物的分类、矿物质的名称在此篇文章中大聚会，来检测下背过的词以类记吧!

　　1. Mineral deficiencies can often be detected by specific symptoms such as chlorosis (loss of chlorophyll resulting in yellow or white leaf tissue), necrosis (isolated dead patches), anthocyanin formation (development of deep red pigmentation of leaves or stem), stuntedgrowth, and development of woody tissue in an herbaceous plant.(在阅读中遇到背过的单词，是不是很有成就感?)

　　2. A survey of known hyperaccumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc,manganese, lead, and cadmium are other minerals of choice.(一团团的都是什么矿物质?)

　　3. This technique allows researchers tocreate solutions that selectively omit certain nutrients and then observe the resulting effects on the plants.(细节题的定位不能生硬地依靠词汇的对应，能理解allow和advantage之间的联系吗?)

　　4. Only recently have investigators considered using these plants to clean up soil and waste sites that have been contaminated by toxic levels of heavy metals–an environmentally friendly approach known as phytoremediation.(仿写下本句中的倒装和同位语吧!)

　　5. This scenario begins with the planting of hyperaccumulating species in the target area, such as an abandoned mine or an irrigation pond contaminated by runoff.(不难的句子简化题，注意其中的指代。)

　　6. After several years of cultivation and harvest, the site would be restored at a cost much lower than the price of excavation and reburial, the standard practice for remediation of contaminated soils.(对比是本句的考点，也是题目的定位点。)

　　附： Jennifer Pan and Margaret Roberts wrote in a study published this May in theAmerican Political Science Review, “TheChinese people are individually free but collectively in chains.” 身为个体的中国人都是自由的，但组成团体时，他们就会披上枷锁。(如果不明白，具体见： http://harvardmagazine.com/2013/09/reverse-engineering-chinese-censorship)
