Learning objectives Activity 1 Underline the following sentences in the reading passage. a. ...50 per cent of my time was spent researching new restaurants. b. Every recommendation she gives me is great... c. ...almost 50 per cent of US jobs are at risk from automation in the next 20 years. d. ...none of us is prepared for the challenges of AI. Activity 2 Look at the sentences you underlined and answer the questions. a. ...50 per cent of my time was spent researching new restaurants. c. ...almost 50 per cent of US jobs are at risk from automation in the next 20 years. Q1:Why is 50 per cent singular in sentence (a) but plural in sentence (c) Because in sentence (a), the part “50 per cent” is followed by the uncountable noun “time”, while in sentence (c), the part “50 per cent” is followed by the countable noun “job” in its plural. Q2:What are the subjects in sentences (b) and (d) Are they singural or plural b. Every recommendation she gives me is great... d. ...none of us is prepared for the challenges of AI. In sentence (b), the part “Every recommedation” is the subject. In sentence (d), the part “none of us” is the subject. Both are singural. Activity 2 Look at the sentences you underlined and answer the questions. Now look for more sentences following this rule in the reading passage. The technology you’re using and enjoying today is a basic form of AI which can’t think independently without programming. Machine-learning is something we have come to accept as a part of our modern world. I believe most of the value of AI lies in its capacity to analyse and interpret vast amounts of data, ... One thing I think we all agree on, though, is that saying “My AI did it!” won’t be any excuse for illegal or immoral behaviour! 主谓一致是指主语和谓语在人称和数上保持一致。 考查重点：名词作主语时的谓语形式；分隔情况下，主语和谓语的一致；分数，百分数，不定式，动名词作主语时的主谓一致；并列主语的主谓一致；定语从句中的主谓一致；倒装句中的主谓一致。 主谓一致 语法一致：主语和谓语在人称和数上一致 意义一致：谓语的单复数与主语的意义一致 就近一致：谓语形式与其临近的主语在人称和数上一致 Activity 3 Summarise the use of subject-verb agreement. 1. 主语是集体名词时，如：group, family, class, government, team, pubic, enemy, crowd, audience, club, party, crew等时，如果看成一个整体，谓语动词用单数形式，如果侧重其成员，谓语动词用复数形式。 例句： My family has four people. My family all like watching football games. The audience was enormous. The audience were greatly moved by the hero's words. 2.主语是单复数同形的名词时，如：deer, sheep, fish, series, means, works等，视其表达的意义而判断谓语动词的单复数形式。 例句： Every means has been tried, but none proved successful.
