今天的翻译题是：
1.____________________(无论别人怎么说)，he held on to his beliefs.
1.You had better not disturb Mary as she ___________________(正专心于解一道难题).
答案解析:
1.答案:No matter what was said//Whatever was said
详解:
考查让步状语从句:no matter what/when/where/who/which/how结构可以引导让步状语结构，意思是“无论什么，无论何时，无论何处，无论谁，无论哪一个，无论如何”，分别等同于whatever/whenever/wherever/whoever/whichever/howver,句中“无论别人怎么说”，意即“无论别人说什么”，用no matter what或whatever引导。
考查被动语态:从句中what/whatever作主语，与“说”直接属于被动关系，所以用被动语态。
2.答案:is absored/involved in working on a puzzle
详解:
考查词组:“专心于”的表达是be absorbed in或be involved in,后面需接名词性成分。
考查work on的使用。Work on意为“从事，忙于”，根据语法需要变为working on。
