Look at the sentences and answer the questions.
Why is 50 per cent singular in sentence (a) but plural in sentence (c)
What are the subjects in sentences (b) and (d) Are they singular or plural
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.
P41
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 form.
Look at the sentences and answer the questions.
P41
b Every recommendation she gives me is great ...
d … none of us is prepared for the challenges of AI.
Q2. What are the subjects in sentences (b) and (d) Are they
singular or plural
In sentence (b), the part “Every recommendation” is the subject. In sentence (d), the part “ none of us” is the subject. Both are singular.
Look at the sentences and answer the questions.
P41
Task 1: Now look for more sentences following this rule in the reading passage, and summarise the use of subject-verb agreement in your own words.
Nearly every job is potentially at risk in the long run. (P39)
2. 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. (P39)
主谓一致是指主语和谓语在人称和数等方面的一致，当主语是不定代词或含有修饰语时，谓语动词的形式要依据主语所表达的单、复数概念而定，而不仅仅是取决于简单的外在形式。
Subject-verb agreement
主谓一致
用法归纳 1: 当主语被分数（百分数）、表示量的词汇等修饰时，谓语动词的形式要依据主语本身进行判断，具体如下：
如果主语是可数名词复数，或主语加上修饰语后整体表达的是复数概念，那么谓语动词要用复数形式。
如果主语本身是可数名词单数或者不可数名词，则谓语动词要用单数形式；
例1：About one-third of the books in the library are donated by students who
graduated from the school.
图书馆里大约三分之一的书都是由这所学校的毕业生捐赠的。
解析：book 是可数名词，在句中是复数形式，并且在句中着重于书的数量而不是将书视为整体，因此“三分之一的书”表达的意义是复数概念，谓语动词用 are。
Subject-verb agreement
例2：Around 10 per cent of the forest is destroyed each year.
每年大约有10%的森林被毁。
解析：本句中的 the forest 为可数名词的单数形式，泛指森林，因此“10%的森林”视作一个整体，谓语动词用 is。
例3：A large number of people have applied for the job.
许多人都申请了这份工作。
解析：本句中的 people 为集体名词，表示复数概念，因此谓语动词用 have。
1) Fifty percent of the students in our school ____ girls.
2) Three-fourths of the surface of the earth ____ sea.
3) Over sixty percent of the city _____ destroyed in the war.
are
is
was
1) 主语本身为可数名词复数 students，故用are。
2) 主语为 surface“表面”，且句中“地球表面的四分之三”为整体概念，故用 is。
3) 主语为 city，在此为可数名词单数，故用 was。
Practice
解析

用法归纳 2：常用的表示“量”的短语后面接名词的谓语情况。
1) a number of / a variety of / varieties of +可数名词复数作主语时，谓语动词用复数形式。
a large amount of +不可数名词，谓语动词用单数；
large amounts of +不可数名词， 谓语动词用复数。
A number of new houses have been built there.
A variety of products are on sale now.
A large amount of money was spent on the bridge.
Large amounts of money were spent on the bridge.
Subject-verb agreement
主谓一致
用法归纳 3：当主语被不定代词修饰或主语本身是不定代词时，谓语动词的形式需要根据主语加上修饰语后整体表达的意义来进行判断。
例：Every means has been tried out without much result.
所有方法都试过了，却没有什么效果。
解析：means 是“方法” 的意思，every means 强调“每一种方法” ，故谓语动词用单数形式。
1) Each boy ______ a prize.
2) Many of us _____ gone through regular training.
3) Every possible approach ____ been tried, but in vain.
4) Both of the instruments ____ not precise ones.
5) Something ___ going to happen, and nobody can stop it from happening.

用法归纳 4：all 作主语表示人时，谓语动词用复数；表示物时，谓语动词用单数，如：
例1：All is well that ends well. 结果好一切都好。
例2：All are eager to reach an agreement. 大家都急于达成一项协议。
用法归纳 5：none 作主语时，谓语动词既可用单数也可用复数，这要取决于说话人的看法，如：
例1： None of us seem to have thought of it.似乎我们全都没有想到这一点。
（此处强调全体，全部都没有想到。）
例2： None of us has got a camera. (none = not a single one)我们都没有照相机。
（此处强调每一个个体，没有一个有照相机的。）
Subject-verb agreement
主谓一致
用法归纳 6：当主语被否定词修饰或主语本身是否定词时，谓语动词一般用单数形式。如：
例1：Nobody has got a ticket. 谁都没有票。
例2：Nothing was available. 没有可用的。
Task 2: Complete the passage by choosing the singular or plural form. (P41)

Last week, we asked you to design your ideal planet for people on Earth to live on in the 22nd century. We have received over 500 entries and have been amazed by your imaginations! Here’s one of the designs.

Task 3: Complete the description according to the charts, paying attention to subject-verb agreement. (P41)
Three quarters of the surface is made up of land, while the rest is sea, covering 25% of the surface.
Half of the land is covered with trees. Residential area and arable land both account for the same proportion, 20% of the total land. The rest is desert, covering 10% of the total land.
There are three kinds of people. Fifty per cent of the people are original residents, 30% are from Earth and 20% are from other planets.

Time travel could result in a paradox — an event that contradicts itself. For example, if a person travelled back in time and prevented an event, that event would never have happened; there would therefore be no reason for the person to travel back in time to prevent it.
Task 1: Listen to the conversation and choose its main idea.
1. Time travel is dangerous.
2. Talking to people in the past can change the future.
3. Anything you say or do in the past can affect the future.
4. Time travel within your own lifetime should be avoided.

Task 1: Read the passage and put the expressions in bold into the boxes.
Besides time travel, we have much to look forward to in the future, thanks to advances in technology. One area that is likely to change dramatically within our lifetimes is medical care. Although I wouldn’t bank on patients feeling confident about seeing a robot doctor any time soon, I’m sure that AI doctors are on the horizon. I think it’s also fair to say that we can get our hopes up when it comes to finding cures for serious diseases, such as cancer. I reckon that nanorobots that can eliminate cancerous cells are just around the corner. Some of these ideas may sound far ahead of their time, but I’m sure they’re bound to happen sooner or later!
