Electric cars may seem like a recent invention but they have been around for years. In the early 1990s there were 11 electric cars on the road than gasoline cars, because at that time, gasoline was expensive compared with other fuels (燃料), electric cars were more popular.
When gasoline prices dropped and new 12 on gasoline cars were developed, electric cars were out of date. Gasoline cars became more popular 13 , because they could go farther without stopping.
During the 20th century, gasoline cars got bigger, heavier and faster. They needed more fuels, and it 14 more air pollution. For years, the car makers didn’t worry about pollution. They didn’t worry about how much gasoline cars used, either. But when people began to 15 that there was not enough oil on the earth, they asked car makers to produce more efficient and less polluting cars.
One 16 of solving the problem was a “hybrid” car (混合动力车), one that ran partly on gasoline and partly on electricity. Hybrid cars became popular in the 2000s because gasoline prices went up while prices of hybrid cars went 17 .
An all-electric car uses no gasoline. The problem, however, is that car batteries need to be recharged (充电). That makes electric cars not so 18 for long journeys. So many people are not pleased with it. The government and car makers are working together to 19 safe, cheap and useful electric cars. When more people have these electric cars in the future, a gasoline station may 20 . We hope that our life will be better.

Thera-Paw’s team created a 24 pair of shoes for Lucas. “It can help Lucas fully join the group and show behavior more typical for a penguin— 25 climbing the rocks and swimming.

三、阅读理解
Over a million people around the world lose their lives to car accidents（事故）each year. While nearly all of these deaths are the consequence of human mistakes, there are no good ways to reduce the number of deaths. Surely one of the best plans is driverless technology.
Driverless cars are no longer an idea of the future. With the technology for the driverless car already developed for quite a long time, and some important inventions already seen in some cars, the driverless car could soon be with us.
This is wonderful because driverless technology is expected to reduce the number of road deaths. A research group in the United Kingdom says that driverless cars will lead to 2,500 fewer road deaths before 2030.
How are driverless cars safer Firstly, driverless cars can help manage traffic. By using communication technologies to “talk” to each other, driverless cars find the best roads. Information such as distance（距离）between cars, traffic and time is sent to the cars. This means fewer chances of these cars running into each other. Secondly, the use of driverless cars means fewer accidents will happen because of human mistakes. For example, accidents caused by little sleep or drunk driving will be avoided. Finally, the driverless technology of the future, is expected to be more reliable（可靠）than a human driver.
If lives can be saved by driverless cars, let’s hope these cars will be on our roads very soon.
31．The underlined word “consequence” has the closest meaning to “________”.
A．result B．news C．chance D．opinion
32．What is Paragraph 4 mainly about
A．The cause of road deaths. B．The management of traffic.
C．The safety of driverless cars. D．The development of driverless technology.
33．It is the writer’s wish that driverless cars could be ________.
A．improved B．put into use C．invented D．researched
Paper is one of the most important products ever invented by man. The invention of paper meant that more people could be educated because more books could be printed. Paper provided an important way to spread information.
According to Chinese written historical records, paper was made in about AD 105 by Cai Lun, an official during the Han Dynasty. He took the inner bark of a tree and bamboo, mixed them with water, and pounded them with a wooden tool. He then put this mixture onto a piece of cloth and let the water through, leaving only the fibers (纤维) on the cloth. After it dried, Cai Lun discovered that he had created a good writing thing—paper. It was easy to make and take.
Chinese papermaking was introduced to Korea and Vietnam and later to Japan at the beginning of the 3rd century. It was a valued export (出口) in Silk Road trading, but the papermaking process was kept secret.
During the Tang Dynasty and the Song Dynasty, different kinds of paper were developed including bamboo paper and xuan paper.
By the end of the 7th century, the papermaking process reached India, Nepal, Pakistan and Bangladesh. In about AD 751 after an important war, the secret of papermaking was gotten from two Chinese prisoners (囚犯) caught by the enemies. The invention was then spread to Europe.
After many years, the invention had been spread all over the world and people thought it was one of the most important inventions. Today, both paper and paper money are used in all corners.
34．What did the invention of paper mean
A．More people could spend money on books.
B．More people got the chance to be educated.
C．People could exchange information with each other.
35．What’s the meaning of the underlined word “pounded” in the second paragraph
A．捣碎 B．覆盖 C．晾晒
36．Which of the following happened earliest
A．The papermaking process reached Nepal.
B．Bamboo paper and xuan paper were developed.
C．Chinese papermaking was an export in Silk Road trading.
37．What can we know according to Paragraph 5
A．The papermaking process was spread only in Asia.
B．The two Chinese prisoners knew the secret of papermaking.
C．The Chinese didn’t offer the methods of making paper to Europeans.
38．What’s the passage mainly about
A．The invention and spread of paper.
B．The famous ancient inventor Cai Lun.
C．The materials and process of making paper.
A lot of people think that wind power is new but that’s not true. For thousands of years, people have used wind to sail (航行) boats and move water. We still do those things today, but these days we mainly use wind power to make electricity.
Wind power is a very popular source of energy. Most people think we should use it more and more. First of all, it’s clean. It doesn’t pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. Also, wind power is cheap and it’s getting even cheaper.
A lot of people don’t understand wind power very well. They believe there are problems with wind power, but many of those problems are not real. For example, some people say windmills (风车) are dangerous for birds. They used to be true, but it isn’t true any more. Old windmills killed birds because they spun (旋转) very fast. New windmills spin slowly, so they aren’t dangerous for birds.
However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for people, because windmills are often in very pretty areas. Also, wind doesn’t blow all the time, so we can’t use wind power all the time. Finally, windmills are noisy.
Although there are several problems, wind power is becoming more and more common. Right now, more than 80 countries use wind power, About 2.5 percent of the world’s power comes from the wind.
39．Which picture can best describe the underlined sentence
A． B． C． D．
40．Which of the following is TRUE
A．People can use wind power all the time.
B．Windmills used to be dangerous for birds.
C．People have used wind to make electricity for thousands of years.
D．About one fourth of the world’s power comes from the wind.
41．What’s the writer’s purpose of writing this passage
A．To tell people that windmills are noisy.
B．To tell people that windmills are dangerous.
C．To let people know that wind power is new.
D．To let people know more about wind power.
42．With what method does the writer describe the use of wind power in the last paragraph
A．By giving examples B．By listing numbers (列数字)
C．By asking questions D．By making comparison (作比较)
43．What’s the best title for the passage
A．The Advantages of Wind Power B．The Disadvantages of Wind Power
C．Wind Power D．Windmills
Robot fools humans
The idea that robots could one day be our friends has been around for a long time but until now they have always seemed more machine than person. A new study by a researcher at the Italian Institute of Technology has found that in fact it’s possible for robots to fool us here and there, they are just less perfect than human. Inspired by the Turing Test, Agnieszka Wykowska came up with an experiment using a child-sized human-like robot called iCub. Sitting in front of a screen, the people in the test were asked to press a button when a green box appeared on the screen, however, iCub only responded to red boxes Wykowska programmed the robot to take different lengths of time to respond, just like a person would. Afterwards, the humans were asked to judge whether they had been competing with a machine or a person according to the time of the buttions being pressed—and they couldn’t tell. Wykowska believes that making robots have more human responses is the key to making better robots and creating more trust between humans and robots.
In another study with iCub, the robot and a human watched special videos of animals. In the first set of tests, iCub greeted the person, asked for his name and kept eye contact with its camera “eyes”. It made comments about the videos, laughed and showed emotions (情感). In the second experiment, however, iCub did not communicate with human and just made machine-like noises. The researchers found that people believe that the more human iCub is, the more it has its own thoughts and desires. The team now wants to know if people can communicate with robots that do not look human but that still show human-like actions. The researchers plan to repeat the experiments, using robots of different shapes and sizes, to see how people give their responses.
44．A new study at the Italian Institute of Technology has found that robots________.
A．aren’t so clever as machines B．can possibly fool us here and there
C．are more perfect than human D．plan to do a lot of research work
45．ICub in this article is________.
A．a researcher at the Italian Institute B．an experiment Wykowska did
C．a child-sized human-like robot D．a button people pressed in the test
46．People couldn’t tell whether they are competing with a human or an iCub according to________.
A．the green boxes people used B．the time of the button being pressed
C．the trust between humans and robots D．the red boxes iCub responded
47．In the first set of another study, iCub didn’t________ with a human.
A．watch special videos of humans B．keep eye contact with its camera “eyes”
C．greet the person and ask for his name D．make comments and show emotions
48．In the second experiment, people believe that if iCub is more human-like, it has ________.
A．more machine-like noises B．more human-like actions
C．more different shapes and sizes D．more thoughts and desires of its own
49．Which information is RIGHT in this passage
A．Robots are no longer machines and they have been our friends for a long time.
B．Wykowska did some experiments but failed to find if iCub had any human responses.
C．The researchers plan to do the experiment again to see how people will respond
D．In the second test, iCub didn’t communicate with human because it became foolish.

1．C
【详解】句意：——所有的学生都知道我们这周六要考英语吗？——是的。每个学生都被告知了这件事。
考查被动语态。主语“Every student”与动词tell之间是被动关系，表示被告知这件事，所以此处用被动语态结构，故选C。
2．C
【详解】句意：——我听说你上周日参加了森林清理活动。——是的。我们学校的环保俱乐部组织了这次活动来保护森林。
考查动词的时态和语态。根据“last Sunday”可知是过去的事，是一般过去时。主语“it”指的是“a forest clean-up activity”，和动词之间是被动关系，表达“被组织”用一般过去时的被动结构“was organized”。故选C。

4．D
【详解】试题分析：根据语境可知此句的含义是第一个地球日是在1970年举行的。考查的是被动语态的基本构成，因描述的是过去时故用一般过去时的被动语态，其基本构成就是was或were+动词的过去分词，主语是单数故用was，而celebrate的过去分词是celebrated故选D。
考点：一般过去时的被动语态
点评：被动语态表示主语是动作的承受者。被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。汉语往往用“被”、“受”、“给”等词来表示被动意义。被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此
5．B
【详解】句意：——你能听懂演讲者在说什么吗，凯茜？——不好意思，他说的太快我几乎无法理解他。
考查副词词义辨析。nearly几乎；hardly几乎不；probably可能；exactly到底。根据上文的“Can you catch what the speakeria saying”和回答“sorry, he speaks so fast”可以推测没有听懂。hardly具有否定含义，表示“几乎不”。故选B。
6．D
【详解】句意：去年这个城市建了一个新的国际机场。
考查时态和语态。根据“last year”可知用一般过去时；主语“A new international airport”与动词build之间是动宾关系，用被动语态。一般过去时的被动语态结构为was/were built。故选D。
