11.trembled at sth相当于焦虑、担忧;根据横线后的at选择C.句意为:一想到要在所有老师面前作演讲,我就不寒而栗.
12.as 后只能用 that,不能用 which
13.devote sth to 是固定搭配,把……奉献给……
“that Marie and the Joliet-curies ________their lives to ”是定语从句,第二个横线上的 caused是主句的谓语动词,所以应用一般过去时
14.这是一个部分倒装句
由于否定词not放在句首,所以应该使用部分倒装,此句相当于“we couldn't understand a word”
15.problem 是被听见,并且是被别人提到,所以应该用过去分词mentioned做主语的补足语,所以选A
