24、法所打动。【句子分析】本句话为“more than one+单数名词”作主语的句子。虽然more than one意为“不止一个”,但它的谓语动词单复数却要从形式一致角度考虑。通常用单数。文中另两处以“more than one+单数名词”作主语的句子分别为:.more than one scientist has questioned what really happened.(Para.4);In fact,more than one account suggests that while Newton was certainly inspired by a falling apple,.

27、towards later scientific discoveries and inventions.富兰克林与许多其他科学家一道,激励并教导我们科学实验对于推动真理与推动科学发现及发明而言都至关重要。【句子分析】本句是主从复合句,其中that引导宾语从句。has inspired和taught是主句的并列谓语。动词不定式作目的状语“along with/as well as+名词”置于主语后,谓语动词一般与其前面的主语在数上保持一致,即单数主语需用单数谓语,复数主语需用谓语复数。eg:Tom,along with his parents,goes to the park every Sun

30、钥匙的话,他肯定就被电击致死了。【句子分析】(1)本句是主从复合句。其中that.the electric shock是that引导的宾语从句;该从句也是主从复合句,其中if Franklin.the key是条件状语从句,该从句及其主句he would certainly have died from the electric shock都使用了虚拟语气。【拓展延伸】虚拟语气虚拟语气表示说话者做出的假设而非事实,或难以实现的情况,甚至表达彻底相反的概念。此外如需表达主观愿望或某种强烈的感情时,也可用虚拟语气。虚拟语气由句中谓语动词的特殊形式表示。(1)表示与现在事实相反的情况:从句:If+主

34、the head是that引导的同位语从句。(2)句中的in fact是固定短语,意为“事实上”。Eg:It clearly showed that while likability can lead to healthy adjustment,high status has just the opposite effect on us.这清楚地表明,尽管受人爱戴可以促进健康的调整,但地位高却对我们产生相反的影响。Activity 2:Complete the summary with the correct words or the correct forms of the words in
