Imagine a town with crosswalks but no pedestrians, cars and trucks but no drivers. Welcome to Mcity, a fake “city” built by researchers who are testing out the driverless cars of the future.

The controlled test environment, which opened today (July 20, 2015) at the University of Michigan in Ann Arbor, covers 32 acres (the size of about 24 football fields) and contains all the trappings of a real suburb or small city. There is an entire network of roads lined with sidewalks, streetlights, stop signs and traffic signals. There’s even a “downtown” area complete with fake buildings and outdoor dining areas.

The idea behind Mcity is simple: test out new driverless car innovations in a human-free environment before these technologies are unleashed in the real world.

"Mcity is a safe, controlled, and realistic environment where we are going to figure out how the incredible potential of connected and automated vehicles can be realized quickly, efficiently and safely," Peter Sweatman, director of the Mobility Transformation Center at U-M, said in a statement.

The roads of Mcity are built to stand up to “rigorous, repeatable” testing, according to MTC officials. While Mcity drivers don't have to compete with real pedestrians, there will be one mechanical foot-traveler (a robot-like machine named Sebastian) that steps out into traffic to see whether the automated cars can hit the brakes in time. The fake city also features a traffic circle, a bridge, a tunnel, some unpaved roads, and even a four-lane highway with entrance and exit ramps, according to a report by Bloomberg Business.

In addition to evaluating fully automated, or driverless cars, the researchers also hope to test out so-called connected vehicles within Mcity’s limits. Connected cars can either communicate with one another (vehicle-to-vehicle control, or V2V) or with pieces of equipment, such as traffic lights, that are located near roadways (vehicle-to-infrastructure control, or V2I).

Even the smallest details of Mcity have been planned out in advance to copy the conditions that connected and automated vehicles could face in the real world. For example, there are street signs covered up with graffiti, and faded yellow and white lane markings line the streets.

Mcity is just one part of a much larger project that MTC and its partner organizations are establishing in an effort to get a whole fleet of connected and driverless cars on the road in Ann Arbor by 2021. In addition to the fake city, MTC is also continuing to launch connected and semi-autonomous(半自动) cars on real roadways. Eventually, the University of Michigan and the Michigan Department of Transportation said they hope to put 20,000 connected cars on the roads of southern Michigan.

1.According to the passage, Mcity ________.

A.is a real town used to evaluate the function of future cars

B.is a fake city with transportation system but no pedestrians

C.covers an area of 32 acres with as many as 24 football fields

D.owns a downtown area with a bridge and some unpaved roads

2.Why did researchers build Mcity?

A.To test new driverless cars.

B.To make a real suburb or small city.

C.To control road environment.

D.To build an entire network of roads.

3.It can be inferred from the passage that ________.

A.some connected and semi-autonomous cars have been put into use

B.the researchers plans to create a robot-like machine to direct the traffic

C.the widespread use of driverless cars will soon come into reality in America

D.MTC is attempting to make connected and driverless cars available on real roads

4.How does the passage mainly develop?

A.By presenting descriptions of the design.

Everyone would like to be a millionaire , a person with a lot of money, but can you imagine having over $30 million and only being 20 years old? Britney Spears from Kentwood, a small town in Louisiana, is only 20 years old. She is a world famous film star with not only $30 million but also a $2 million house in LA. At her young age, she can look after her family financially all her life. This year is a big year for Britney. She is now on a 31-day tour of the US and every concert is a sell-out. That means she plays in front of a crowd of around 18,000 people every time. It’s a tiring schedule but brings her a lot. When touring, she goes to bed around 1 a.m. and then has a lie-in until 1 p.m. the next day. Her philosophy is to take care of the body and relax but always make sure you work hard and have fun.

Spears is not pleased with only touring and selling nearly 40 million records so she decided to step into the movie business and try a bit of acting. She made an appearance in “Austin Power 3” this year and she is filming a teenage light play that will come out in March 2003. In this movie, she has a starring role.

For Britney, acting is another way to express herself and she is enthusiastic about it all. If her movies are successful, her money in the bank is sure to grow by another few million dollars but she does it for the love, not the money, as she herself tells the reporters .

1.We can infer from the text that most millionaires are __________.

A. older than 20　　 B. around 20

C. in their 30s　　 D. in their 40s

2.The underlined word “you” in the first paragraph refers to __________.

A. a person in general　　 B. a special person

C. Britney Spears　　 D. a person interested in money

3.Which of the following is not true according to the text?

A. Though young, Britney can support her family now.

C. The teenage comedy movie was based on Britney’s own story.

What can you imagine the life 100 years from now? In fact, no one can know it from now, but scientists studying the evolution of the society, human life and the world in general make such kind of predictions based on scientific data. According to their publications in scientific journals, let’s see how the world might look like in 100 years from now.

Embedded computers

According to predictions by Ian Pearson and Patrick Tucker, by 2050 the human body will be embedded2 with computers, at least in a big part of the population, and by 2075 most of the citizens of the developed world will have some kind of chips built in their brains to make them work faster and share thoughts in the form of computer data.

Superhuman geniuses

Developments in genetic engineering will create human geniuses who will live forever. Does it sound unbelievable? It is sure that there will be a way to influence the brain to increase the intelligence level and with the help of genetics it will be possible to maintain human body for many years.

Global currency

According to futurists, it is very likely that a global electronic currency will be created. They say that the local and national currencies will be few until mid-century and will gradually disappear, let alone metal currencies.

Three world languages

There will be only three world languages: English, Spanish and Chinese. Other languages will have no chance to survive through time. Futurists say that many minority languages are already extinct and the fac t that all educated people in the world speak at least one of these languages will help in this way.

Oceans as a food source

It is one of the most “confident” future devel opments, according to scientists, because if the world population continues growing at the same rate, it will reach ten billion. So the food will not be enough. Thus the oceans will be used to raise fish and to provide populations with fresh water taken from the sea plants.

Journeys into space

Most futurists agree on this and believe that some kind of tourist attractions will be created in space, although they will be affordable only for wealthy people.

1.Why will there be only English, Spanish and Chinese according to the passage?

A. Because other languages won’t be important.

B. Because people who speak minority languages won’t be willing to speak their native languages.

C. Because more and more educated people speak English, Spanish and Chinese, which will cause many minority languages extinct

D. Because in the whole world all the people must not speak other languages.

2.What currency can we use to buy goods in the future from the passage?

A. local currency　　 B. metal currency

C. national currency　　 D. global electronic currency

3.The main idea about the passage is about        .

A. what the people look like 100 years  from now .

B. what the life of people is like 100 years from now.

C. what the environment is like 100 years from now.

D. what the culture is like100 years from now.

Imagine you are in a jumping contest. Animals and insects can also enter this contest. But they might just leave humans in the dust!

The first event is the long jump. The human athlete is Mike Powell. In 1991, he jumped nearly 30 feet, which is the world record for the long jump. That is about five times his own height.

His competitor in the long-jump contest is a frog named “Rosie the Ribbiter.” Rosie set the world record for frogs in 1986 by jumping more than 21 feet. Her record has never been broken by any other frog. Compared to Mike Powell, Rosie’s jump is not that amazing. But wait! Rosie is only about 10 inches long when her legs are stretched to their full length. She can jump more than 25 times her size. Rosie, the frog, wins the long-jump event.

The next event is the high jump. Javier Sotomayor, the world record holder, can jump a bar (横杆) 8 feet high. That is about as high as the ceiling in most homes.

Looking around for someone to challenge his record, Javier might need a magnifying glass (放大镜). The next contestant is a tiny insect called the spittlebug (吹沫虫).

The spittlebug can jump 28 inches into the air. It is only a quarter-inch long, less than the width of a pencil. If the spittlebug were the same size as Javier, it would be able to jump 600 feet into the air. That is like a human jumping over a building 55 stories high!

Though the humans lose the “jumping contest,” their competitors would probably agree that Mike and Javier are still pretty excellent athletes. If only Rosie and the spittlebug could speak!

1.The underlined word “contestant” in Paragraph 5 means “_____”.

A. coach            B. teammate            C. challenger        D. record holder

2.What can we learn about the spittlebug?

A. It likes living on the ceiling.

B. It is good at flying in the air.

C. It is the same length as a pencil.

D. It has a wonderful jumping talent.

3.In the author’s opinion, Rosie and the spittlebug’s jumping abilities are ________.

A. surprising        B. promising        C. doubtful            D. fearful

4.How does the author develop the text?

A. By giving instructions.

B. By making comparisons.

C. By following the order of time.

D. By following the order of importance.
