答案 B
解析 這句話 suggest后面是一個(gè)when引導(dǎo)的從句 其主句 he should be especially careful to have a well-balanced diet要用虛擬語(yǔ)氣 而從句when.不需要用虛擬語(yǔ)氣 只要用正常的時(shí)態(tài)即可
翻譯 這篇文章建議 當(dāng)一個(gè)人處于不同尋常的壓力之中時(shí) 他應(yīng)該特別注意膳食平衡.
樓主把后半句顛倒順序就可以看得更清楚即
The article suggests that a person should be especially careful to have a well-balanced diet when he is under unusual stress.
又如 爸爸建議我睡覺(jué)之前就把作業(yè)寫(xiě)完 應(yīng)該表達(dá)為
Dad suggests that I should finish my homework before I go to bed.
而不是 Dad suggests that I should finish my homework before I should go to bed.
