短语

英语中的短语是有一定意义但不构成独立从句或句子的一组词。从形式结构角度划分，英语的短语可分为名词短语、动词短语、形容词短语、副词短语、介词短语等。英语短语的句法功能通常与对应的单词的句法功能类似。

[观察例句]

1．So I've been here in the jungle for about a month now.

2．My secondary school is a bush school.

3．It takes me only a few minutes to walk to school down a dusty track covered in weeds.

4．I've had to become much more imaginative in my teaching.

5．Right now I'm feeling very excited.

[归纳用法]

1．例句1中的黑体部分为介词短语。

2．例句2中的黑体部分为名词短语。

3．例句3中的黑体部分为动词短语。

4．例句4中的黑体部分为形容词短语。

5．例句5中的黑体部分为副词短语。

一、名词短语

名词与它的修饰语一起即构成名词短语。完整的名词短语由三个部分组成：限定词、修饰词、名词。名词短语可以充当句子中的主语、宾语、表语等成分。

many good students 许多优秀的学生

his beautiful wife 他美丽的妻子

the best answer 最好的答案

those sweet roses 那些甜美的玫瑰

These red roses are for you.(作主语)这些红玫瑰是送给你的。

He brought a new book with him.(作宾语) 他带来了一本新书。

He is my best friend.(作表语)他是我最好的朋友。

名词短语的三个部分并非每一次都要同时出现，在特定场合下，这三个部分都有可能省略。修饰词是名词短语中最不重要的部分，如果不需要描述名词的状态特征则完全可以省略。比如a book同样是正确的名词短语。如果说话人确信听众知道自己在讨论什么东西，则名词也可以省略。比如Of those answers，this one is the best.这里的the best指的就是the best answer。在面对面交流的时候，修饰词和名词有时甚至可以一起省略。假设你在花店，用手指向一捧玫瑰花，对花店老板说“I want those.”的话，花店老板很清楚你想要什么。

[即学即练1]

找出下列句中的名词短语，并指出其作什么成分。

①I have three close friends.

③The cute boy wearing blue jeans is my brother.

【答案】1.three close friends作宾语2.some red roses作主语；that small table作宾语

3.the cute boy作主语；blue jeans作宾语；my brother作表语

二、形容词短语

形容词短语是指由几个形容词或形容词及其修饰语构成的短语。

1．两个或多个形容词可以由and，but等对等连词连接，构成形容词短语。

Your room is large and beautiful.(作表语)你的房间大且美丽。

He is young but clever.(作表语)他年轻但聪明。

2．very等程度副词作修饰语，可与形容词构成形容词短语。

It is very hot today.(作表语)今天很热。

3．介词及其宾语可用在形容词后修饰形容词，可与形容词构成形容词短语。

The bottle is full of water.(作表语)瓶子里装满了水。

4．不定式在形容词后作修饰语，可与形容词构成形容词短语。

He is sure to come.(作表语)他一定会来的。

[名师点津]

形容词短语在句中还可以作状语和后置定语。

1．形容词短语作状语说明主语的情况，可以表示动作或状态发生的原因、方式、时间等，或对谓语作补充说明。

Afraid of difficulty，he prefers to do the easy maths problem.(作原因状语)

他害怕困难，宁愿做容易的数学题。

The lost boy spent three days in the forest cold and hungry.(作伴随状语)

那个迷路的男孩又冷又饿地在森林中过了三天。

Wet or fine，he got up at six and took a walk in the park.(作让步状语)

四、动词短语

动词短语就是有些动词可以和一些别的词构成短语(以动词为中心)，表达一个概念，其作用和一个单独动词差不多的一种固定搭配。在实际使用中，通常会把动词短语当成一个整体。动词短语的搭配可分为下列五种基本类型：

1．动词＋介词

Trains stop here in order to pick up passengers only.

火车在这里停车，只让乘客上车。

[名师点津]

“动词＋副词”这类短语动词较容易出错。这类短语动词的宾语若是名词，这个宾语可在短语的中间，亦可在短语的后面。如：Turn the light on.或 Turn on the light.宾语若是代词，这个宾语只能放在短语的中间。如：Turn it on.

3．动词＋副词＋介词

Your cooperation is requested during snow removal and these suggestions may apply：

* Limit travel during storms.Travel is possible once roads have been cleared or salted by the road crew.

* Avoid removing snow from your driveway into the road.Pile the snow in your yard.

* Park your vehicles in your driveways and off the road or sidewalks.

More than ￡5,500 has been raised after a plea(请愿) last Monday by a vet Dr Scott Miller.Scott said，“I would like to say a massive thank-you to Express readers from myself，from Australia and from the koalas.It’s amazing that people from across the world can see how significant the catastrophe has been.I do appreciate that people are being very supportive and reaching into their pockets.” An area，a third of the size of Britain is estimated to have been ravaged(毁坏) since the blazes(火灾) began in September.

On Friday，a state of emergency was declared in the capital Canberra，with residents told to prepare to evacuate as fires on the outskirts(市郊) threatened to spread.A billion animals are feared to have died，including 25,000 koalas.

Last week Scott told how he had visited his homeland，helping to save wildlife on Kangaroo Island off the coast of Adelaide.While there he rescued a mother and a baby koala who were stuck in a tree.The pair were rushed to a field hospital on the island to be treated.The mum had severe burns to her paws and was badly dehydrated(脱水的)，while her baby son had an eye injury and was underweight.

Scott，who has appeared on ITV’s This Morning and BBC’s Blue Peter，said the mother is showing “great signs of improvement” and her wounds are starting to heal.The baby has undergone surgery to his eye and is “recovering from the anesthetic(麻药) and doing well”．

But he added，“The mother remains dehydrated so it isn’t producing enough milk to feed the baby.At the moment they’re being housed severally but there is the hope that when the baby is a little stronger he will be able to be returned to his mother.”

Even after they recover，the pair will probably spend their lives in an enclosure while the bush takes years to recover.Scott said，“Sadly patients are still coming in thick and fast.Each of these animals is requiring to be housed and fed，and regular medical treatment to their injuries.”

A．Dr Scott donated more than ￡5,500.

B．Residents were asked to move to Canberra.

C．Numerous animals might have lost their lives.

D．A large area of Britain has been badly damaged by the fire.

Why are some people better able to fight off the flu than others? Part of the answer，according to a new study，is related to the first flu strain we encounter in childhood.

Scientists from UCLA and the University of Arizona have found that people’s ability to fight off the flu virus is determined not only by the subtypes of flu they have had throughout their lives，but also by the sequence(顺序) in which they have been infected by those viruses.Their study was published in the open-access journal PLoS Pathogens.The research offers an explanation for why some people become much worse than others when infected with the same strain of the flu virus.

In addition，UCLA scientists，including Professor James Lloyd-Smith，who was also a senior author of the PLoS Pathogens research，recently completed a study that analyzed travel-related screening for the 2019 novel coronavirus(新型冠状病毒)．The researchers reported that screening travelers is not very effective for the 2019 coronavirus—that it will catch less than half of infected travelers，on average—and that most infected travelers are undetectable，meaning that they have no symptoms yet，and are unaware that they have been exposed.So stopping the spread of the virus is not simply a matter of enhancing screening methods at airports and other travel centers.

“This puts the onus(责任，负担) on government officials and public health officials to follow up with travelers after they arrive，to isolate them and trace their contacts if they get sick later，” said Lloyd-Smith，a UCLA professor of ecology and evolutionary biology.“Many governments have started to impose quarantines(隔离)，or even travel bans，as they realize that screening is not sufficient to stop the spread of the coronavirus.”

One major concern，Lloyd-Smith said，is that other countries，especially developing nations，lack the infrastructure and resources for those measures，and are therefore vulnerable to importing the disease.“Much of the public health world is very concerned about the virus being introduced into Africa or India，where large populations exist that do not have access to advanced medical care，” he said.

8．What is the significance of the scientists’ research?

A．It explains the cause of the flu virus.

B．It reduces the risk of people being infected.

C．It analyzes people’s ability to fight off the virus.

D．It stops the spread of the flu virus all around the world.

C【解析】细节理解题。根据第二段最后一句可知，这项研究解释了为什么有些人在感染了相同毒株的流感病毒后会变得比其他人更糟糕。由此可知，这项科学研究的意义就是分析了人们对抗病毒的能力。故选C。

9．What do we know about the novel coronavirus from Paragraph 3?

A．Travelers are at high risk of being exposed to it.

B．It is more difficult to stop its spread than expected.

C．Most travelers infected with it are detected by screening.

D．It spreads especially quickly at airports and railway stations.

B【解析】推理判断题。根据第三段可知，研究人员报告说，对旅行者进行筛查对2019年冠状病毒感染并不是很有效——平均来说，只有不到一半的受感染旅行者会被检测到——而且大多数受感染的旅行者是检测不到的，这意味着他们还没有症状，而且不知道他们已经接触了病毒。由此可知关于新型冠状病毒，阻止它的传播比预期的要困难，故选B。

10．Why does the writer mention Lloyd-Smith’s words in Paragraph 4?

A．To persuade people not to travel.

B．To provide a method to kill the virus.

C．To show the harmful effects of the virus.

D．To stress the responsibilities of officials.

D【解析】推理判断题。根据第四段可知，史密斯的意思是政府要重视隔离和追踪接触者，即史密斯是在强调政府官员的责任。故选D。

11．Which of the following best explains the underlined word “vulnerable” in the last paragraph?

A．Weak.   B．Impossible.

C．Responsible.   D．Indifferent.

A【解析】词义猜测题。根据画线词前半句可知，劳埃德·史密斯说，一个主要的担忧是，其他国家，特别是发展中国家，缺乏采取这些措施的基础设施和资源，由此可知后半句意为“因此很容易输入这种疾病”，因此推断vulnerable的意思是“易受攻击的，脆弱的”，故选A。
