1、考研英语长难句重难点详解分析For examples, in field trials, the plant alpine pennycress removed zinc and cadmium from soils near a zinc smelter, and Indian mustard, native to Pakistan and India, has been effective in reducing levels of selenium salts by 50 percent in contaminated soils.先找生词。trials试验;alpine高山的; pen
2、nycress /peni|kres/S ; zinc 锌; cadmium 镉;smelter 熔炉;mustard 芥末;native to 原产于; reducing 减少;selenium/saliniam/5西;salts 盐; contaminated 污染的;再找主干。本句是并列复合句,由两个简单句组合而成。For examples, in field trials (状语),the plant alpine pennycress (主语)removed (谓语)zinc and cadmium (宾语)from soils near a zinc smelter (状语),比如
3、,在试验田中,高山植物精莫可以 除去锌炉附近田中的锌和镉元素;and (并歹U) Indian mustard (主语),native to Pakistan and India (定语),has been effective (i胃语,系表词)in reducing levels of selenium salts (表语)by 50 percent in contaminated soils (状 语).还有,印度芥末,原产于巴基斯坦和印度,可以有效地减少污染土 壤中50%的硒盐(含量);句子翻译。比如,在试验田中,高山植物拓莫可以除去锌炉附近田中的锌和镉元素, 还有,印度芥末,原产于巴基
4、斯坦和印度,可以有效地减少污染土壤中 50%的硒盐(含量)。Research has focused on the toxic effects of heavy metals such as lead, cadmium, mercury, and aluminum; however, even copper and zinc, which are essential elements, can become toxic in high concentrations.先找生词。focused 聚焦;toxic 有毒的;effects 作用;metals 金属;lead 铅;cadmium/kae
5、dmiam/镉;mercury 水专艮;aluminum 铝;copper 由同;zinc 锌;essential 基本的;concentrations 浓度;再找主干。本句并列复合句。由两个简单句组合而成;后半句中向前推进了一个定 语从句。Research(主语)has focused on(谓语)the toxic effects(宾语) of heavy metals (定语)such as lead, cadmium, mercury, and aluminum (同位语,解释heavy metals ),研究集中在一些有毒性 作用的重金属,比如:铅,镉,水银和铝;非限制定语从句 修饰
