答案:
1.B
[解析]:看新編語法教程,里面說這里than后面是省略了it,還原應(yīng)該是..than it has been put in
2.B
[解析]:上句說人口多對人類發(fā)展造成威脅.而大家要注意這個(gè)yet,yet常用于否定句和疑問句,
也就是說下句應(yīng)該是一個(gè)"否定"上句的句子.,而not more ...than的意思就是 與其說是A ,不如說是B.
這句話.Yet it is probably not more a threat to the human race than environmental destruction.就是與其說是威脅了人類發(fā)展,還不如說是威脅了環(huán)境...
