試題分析：考查不定式，不定式表示目的，句子意思“為了降低房子的價(jià)格，在過去的兩年里一些辦法已經(jīng)被采納”
點(diǎn)評：動(dòng)詞不定式的基本用法：動(dòng)詞不定式能起名詞、形容詞和副詞的作用，可在句中作主語、表語、賓語補(bǔ)足語、定語和狀語用。同時(shí)還要注意動(dòng)詞不定式的被動(dòng)語態(tài)用法：如果動(dòng)詞不定式的邏輯主語為這個(gè)不定式所表示的動(dòng)作的承受者時(shí)，不定式一般就用被動(dòng)語態(tài)形式，如：What is to be done next hasn’t been decided yet.
即學(xué)即練：It’s too late. Go to bed right away. Forget you need to get up as early as you can ______ the early train?
