32.D细节理解题。根据第三段的“ The world's oceans contain an estimated180 billion tons of lithium. But it's thispresent at roughly0.2 parts per million.”可知,据估计,全球海洋中含有1800亿吨锂。但它很薄,大约是千万分之二。故选D项。33.C推理判断题。根据第四段的“ The researchers also changed the way they controlled the electric voltage(电压)After 10 such cycles, taking just minutes, Cui and colleagues ended up with a one-to-one rate of lithium to sodium. "FH上文可知,研究人员改变他们控制的电压经过10次这样的循环,只需要几分钟,C山和他的同事们就得到了锂离子对钠离子的一对一比率。即获得了同等量的锂和钠,而不只是钠。故选C项。34.A主旨大意题。根据整篇文章尤其是第一段的“ the light metal, which is essential for making power-packedrechargeable batteries, isnt abundant. Now, researchers report a major step toward tapping a potentially limitlesslithium supply: pulling it straight out of seawater:”可知,制造充电电池至关重要的轻金属并不充足。现在,研究人员报告了在开发无限锂供应方面的重大进展:直接从海水中提取锂。故选A项35.B推理判断题。根据最后一段的“ That doubles the selectivity, at least,, The advance is still not likely cheapenough to compete with mining lithium on land. .. However, she says her group is attempting to increase selectivityusing other types of lithium- cion battery electrodes."可知,这(海水中抽取锂)至少使选择性增加了一倍。……这进展可能还不够便宜,无法与陆地上的锂矿竞争。…然而,她说她的小组正试图使用其他类型的锂离子电池电极来提高选择性。由此判断,作者对海水中抽取锂这一重要措施采取客观态度,故选B项。,更多内容，请微信搜索关注。
