Kar?go is the invention of the United Kingdom based Academy of Robotics，which describes it as “Europe's first road?worthy autonomous delivery vehicle”. Using AI，this autonomous delivery vehicle offers customers an app—similar to one used when ordering a taxi—allowing them to choose when and where their packages are panies like Tesla and Amazon have invested heavily in autonomous vehicles，which have the potential to create a sea of changes in business and society.
Resembling something like a green egg on wheels，Kar?go's aim is to reduce the cost of what's known as the “last mile delivery challenge”. This is the final stage of your online package's journey，from a local warehouse to your front door.Labor costs，paying drivers，the cost of fuel and the vehicle costs for maintaining small vehicles all contribute to making this the most expensive part of the delivery process. The first part of the package's journey is far cheaper，with high volumes of packages being transported to and from the same location. However，at the other end，drivers deliver smaller shipments to several different locations—where the recipient may not even be available to collect.
With the latest AI technology，Kar?go will deliver goods safely，sustainably and in style. The AI vehicle uses special technology to become an expert on its own individual route，learning from past experiences in order to help itself deal with new future obstacles (障碍物 ) on the road. Kar?go also has its very own internal sorting system，allowing the vehicle to transport packages in the correct order for delivery.
By 2030，the Society of Motor Manufacturers and Traders predicts the autonomous market could add ￡62 billion in economic growth in the UK，creating more than 420，000 new jobs. Electric，self?driving，economic and capable of working 24/7 ，Kar?go promises to reduce the last mile delivery cost by up to 90% ，providing an efficient solution to the rapidly?expanding online retail(零售)market.
4．From the first paragraph we know Kar go________．
A．is an app used to order a taxi

A．How Kar?go delivers the goods.
B．What challenges Kar?go may face.
C．How the drivers reduce delivery cost.
D．Why the last mile delivery is expensive.
6．What is the advantage of the AI technology used by Kar go
A．It has an advanced internal sorting system.
B．It enables vehicles to work more efficiently.
C．It makes a driver become an expert in traffic.
D．It helps people clean new obstacles on the road.

It's impossible to provide an exact number of words in English，since new words are being added to the dictionary，and falling out of use constantly. __1__
The short answer is，about a million. Doubt you know anything even close to a million words That number includes any number of legal，medical，scientific，and mechanical terms that most people will never meet in their day?to?day lives. __2__
The “million” number also includes the many，many words that have fallen out of use throughout the time. __3__ Consider the word “diddle”，a slang term from the 1700s that means “gin”. Many English speakers would recognize “gin”，but far fewer would recognize “diddle”．
If a million words is the absolute upper level，how does that compare with the general vocabulary of most English speakers __4__ Most English speaking adults know between 20，000 and 30，000 words. And in addition to those many thousands of words，they're probably able to comprehend a good 20，000 more just from context clues.
__5__ You won't find a single dictionary anywhere that includes close to the total million words. One of the reasons is that general?usage dictionaries don't include lots of technical terms—both because they are uncommon and，in some cases，because of length. The longest word in the English language is a term from chemistry that is used to identify a certain kind of protein.It is 180，000 letters long. So you certainly won't see it in the dictionary.
A．But what's the number
B．More than you might think!
C．That doesn't amount to a whole lot，though!
D．Then，how many words are there in a dictionary
E. While words like these are very uncommon，they still count.
F．If you recognize these uncommon words，we sadly no longer use them.
G．Though removed from the dictionary，they were still counted as English words.

语篇解读 本文为说明文。文章围绕英语中有多少个单词展开，解释了英语中大约一百万个单词的构成及我们很难找齐全的原因。
1．A [考查承上启下句。根据下文答语“The short answer is，about a million”可知，空处应为问句，提问数量。故A项符合语境。]
2．E [考查细节支撑句。根据前句可知很多专业词汇人们在日常生活中并不会遇到。故后句继续展开陈述，即使这些词汇不常见，但是它们仍然重要。]
3．G [考查细节支撑句。根据空前的“The ‘million' number... many words that have fallen out of use”可知，百万单词包含很多已经不再使用的单词。又根据设空后举的例子“gin”可知，这些词会被很多人认识。故这些不常用的词仍然被算入英语单词。]
4．B [考查细节支撑句。根据设空前的句子可知，一百万个单词绝对是需要很高的水平。但是这是不能与人们常用的词汇相比较的。又根据空后的“Most English?speaking adults know between 20，000 and 30，000 words...just from context clues”可知，尽管人们掌握的常用词达不到一百万那么多，但也不少，也是大家所想不到的。故选B。]
5．D [考查细节支撑句。根据设空后句可知一本词典不可能包括所有近百万的单词。故前句应为对一本词典中所包含单词的数量进行发问。故选D。]

答案：
Dear Louis，
Learning that a meaningful race will be held in our community to celebrate the coming Dragon Boat Festival，I'm writing to invite you to sign up together.
The dragon boat race is one of the most typical traditions of the Dragon Boat Festival.It is said that after the great patriotic poet Qu Yuan committed suicide in a river，people raced out in boats to get his body，which later became a custom of the festival.Now it's a worldwide popular water sport and celebrating activity.To compete in the race，we'd better watch some videos in advance.
Looking forward to your active participation.
Yours，
Li Hua
