最佳答案
哥們/姐們:
1.這句話的原話應該是: There ought to be less anxiety over the perceived rish of mountain climbing than____in the public mind today.
2.答案應該選 a) exists,這一點是不用懷疑的,但是參考所給出的講解卻是錯誤的.這一點我會在下面向你解釋.
a)Than這個單詞只能用作連詞和介詞.連詞和介詞自然而然是不能用作主語的,能作主語的單詞只能是名詞和代詞.基於這一點,就說明參考的解釋是錯誤的.
b)當than用作連詞時,其用於形容詞或副詞的比較級之后,引導表示比較關系的從句和短語.
例如: 1.He's never more annoying than when he's trying to help.(他要是想幫忙就更讓人討厭他.)
2.She's a better player than (she was)last year.(她演得比去年更好.)
c)當than用作介詞時,其用於名詞或代詞前表示比較關系.
例如: 1.You gave me less than him.(你給我的比給他的少.)
2.I am older than you. (我比你年歲大.)
從上面的分析可以看出,你所給出的這句話是一道語法題,即less...than... 而此句的主干部分為 (there ought to be less... than...),than后面應該跟一個句子(than屬於連詞的用法)與there ought to be構成比較關系,但是在這句話中,than后面的句子為了避免重復而省略了主語anxiety(名詞).如果我把這句話完整地恢復出來,你一眼就會明白的.
如: there ought to be less anxiety over the percieved risk of mountain climbing than anxiety (exists) in the public mind today.
爬山時所察覺的危險的焦慮應該要比如今人們內心想象而產生的焦慮要少一些.
