试题分析:英语中有些情态动词,通过使用不同的时态形式,可以表示“推测”的含义。1. 情态动词 + 动词原形:must + 动词原形,表示对现在的事实进行非常有把握的推测,一般用于肯定句。如:There must be something wrong. 一定是出了什么差错。may / might / can / could + 动词原形,表示对现在、未来事情发生的可能性的推测。此时, might, could 不表示过去,只是表示推测的语气更加不肯定。一般情况下, may, might 用于肯定句中; can, could 用于否定句、疑问句中。根据语境可知敲门的人可能是谁呢?不确定有可能是邮递员,故选C。
考点:情态动词表示推测
点评:关于表示推测的情态动词后面所接动词形式,有下列三种情况:若对此刻正在发生的事,接“be +现在分词”;若对现在或未来情况的推测,接动词原形;若对过去情况的推测,接“have +过去分词”。
After a hard campaign, Barack Obama won the US president election on November 4. He will become the 44th President of the United States---the first African-American in the country’s history.
On the election eve, Obama’s grandmother died---only a few days before seeing her grandson’s victory. Tears ran down the face of Obama as he spoke about his grandmother. “She taught me about hard work.She was the one who put off buying a new car or a new dress for herself so that I could have a better life. She poured everything she had into me.”
In his first speech as the president, Obama declared to tens of thousands of cheering supporters, “…The road ahead will be long. Our climb will be steep. We may not get there in one year, or even one term, but America---I have never been more hopeful than I am tonight that we will get there. I promise you: We as a people will get there…” The crowd broke out into the same chant(咏唱,吟诵), “Yes, we can!”Those three short words have become the defining phrase of Obama’s campaign.
Forty-five years ago, Martin Luther King had a dream of an America where men and women would be judged not by the colour of their skin but by the content of their character. Today the dream has come true.
