题目分析:本题的题干部分包含了三个语法现象.第一是插入结构,即两个逗号之间的部分like some other cancers,插入结构在句中不作任何成分,在阅读中如果能够直接看出一句话中的插入结构,就能够排除干扰,对快速理解句子的大意很有帮助.第二个是 not...until...结构.第三个是too...to...结构.虽然后两个结构在中学我们就已经学过,但在新题型的翻译中还是经常会出现的.另外作文中也可以使用这样的表达,对获得高分很有帮助.
考点解析:本题主要是考察对选项四个词语意思的辨别.由题意可知应该选择含有症状意思的词语,即symptom.
注意:
1)trail的词性,既可以做名次也可以做动词.
2)symptom和symbol无论是形状还是意思都比较接近,务必将两个词加以区分.
2.答案:A
