These are some signs that you can see on the roads of Great Britain.

Number one is a sign with the number thirty on it. When drivers see this sign they must not go at more than thirty miles an hour. We see this sign when we get to parts of the country where there are many houses and other buildings, for example, when we are getting near a town. Thirty miles an hour is the speed limit. Number two is sign for the end of the speed limit. We are out of the town now and may go at more than thirty miles an hour. Number three is a sign that we are near a crossroads, that is, a place where two roads cross. We must drive carefully. Number four is a sign that there is a bend in the road. Again, we must drive slowly and carefully. Number five is a sign that there is a hill and number six is a sign that the roads get narrow. Drivers must go slowly and carefully. Number seven has the word “school” on it. This is a sign that there is a school at the side of a street or road. Perhaps there are children going to school or leaving school. So drivers must look carefully and go slowly until they are past the school building.

Number eight is a sign with the letter P on it. The letter P is for “parking.” A parking place is a place where drivers may leave their cars. If the driver of a car wants to leave his car and go to the shops, he looks for this sign. Then he knows that he may leave his or her car there.

Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans work at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. 1.. Because most Americans find they are using their cars in almost every aspect of their life. 2.. The polluted air becomes poisonous and dangerous to health.

3.. That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else.4.. Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down.5..

Although cars have led us to a better life, they have also brought us new problems.

A. Americans know cars very well.

B. Americans won’t live without cars!

C. Inventors are now working on steam cars as well as electric cars.

D. However, the number of vehicles has continued to increase in recent years.

Imagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, informing you of any traffic, pedestrians, animals or other things nearby. Routes and names of road appear over the live stream. It's like the map has come to life.

This type of map isn't available yet. But it could be very soon. In 2014, the WorldView-3 satellite was sent into space. Even though it orbits Earth at more than 370 miles (600km) away, it can take images of objects on Earth that are just 10 inches (25cm) across. Looking all the way from outer space, it can make out a smart phone held in your hand. It can tell what types of cars are travelling down a road. But it can't identify your face or read the cars' license plate numbers.

According to some reports, this satellite and other US satellites have the technology to take even sharper images, with a resolution of up to around 4 inches (10cm). But US law forbids making these super-sharp pictures public. But the idea that anybody might be able to spy on the entire Earth in such detail may seem scary. Live, high-detail satellite mapping could be used to keep tabs on anybody at any time, without the person's knowledge. Ray Purdy of University College London told CNN that he couldn't imagine what this could mean for privacy. "Most satellites are commercially owned, so if you have money, you can have that imagery. It means anyone can spy on anyone." he said.

At the same time, live, detailed maps of the Earth's surface could aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly reveal people in need of rescue as well as the safest routes in or out. Satellites images are already helping the police catch illegal fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops or for scientists to find minerals. Also, these images play a very important role in monitoring the health of forests and other landscapes.

What do you think? Would you like to see everyone accessing high-detail live maps of the Earth's surface? Please share your idea with us on the website.

1.How does the author introduce the topic of the passage?

A.By telling a story.

B.By supposing a situation.

C.By making a comparison.

D.By using a research finding.

2.What can the WorldView-3 satellite do?

A.Tell how a person looks.

B.Identify what a pedestrian is holding.

C.Help farmers sow seeds for their crops.

D.Read a running car's license plate number.

3.What kind of feeling was expressed in Ray Purdy's words?

A.Regret.

B.Excitement.

C.Concern.

D.Sympathy.

4.What's the best title of the passage?

A.Anyone can spy on anyone

B.Criminals have nowhere to hide

C.More satellites into space: good or bad?

D.A live map of everywhere on Earth:scary or cool?

高二英语阅读理解中等难度题查看答案及解析

If you think about the countless number of animal species on our planet, the giraffe is perhaps one of the most interesting. With its unusual pattern and incredibly long neck, it looks like no other animal on Earth. But how did this mammal come to get its famously huge neck? Well, scientists have been asking themselves this question for centuries.

The most commonly believed answer is that the massive neck — which measures on average 180 centimeters and weighs about 270 kilograms — evolved to allow the animal to reach the leaves of tall trees.

British scientist Charles Darwin was one of the first people to propose this idea in the 1800s.“The giraffe… has its whole frame beautifully adapted for browsing on the higher branches of trees,”he wrote in his famous 1859 book On the Origin of Species. It was Darwin’s belief that the giraffe once had a much shorter neck, but over time, evolution led to longer-necked giraffes being born, which in turn survived as they were able to reach the food that others couldn’t. Yet, there are other theories. According to a paper published in September in the Journal of Arid Environments, the giraffe’s neck evolved to increase its surface-area-to-volume ratio. Because the animal’s neck increases its body’s surface area, it makes it easier for it to keep cool, the paper’s authors wrote. This phenomenon can be seen everywhere in nature, and even in engineering.

For example, this is why elephants have such large ears, and why radiators (暖气片) in homes are flat and thin, as a large surface area allows heat to escape quicker.

Meanwhile, some believe that competition is the answer. A 1996 study by two South African zoologists argued that the male giraffes with the biggest necks are the ones who “win” access to females to reproduce, as they are better at fighting, meaning that their long necks are passed down through the generations. So, it seems like there’s still no definite answer to the question. But until we find the truth, we should at least enjoy this beautiful and interesting creature for what it is today, rather than wonder about where it came from.

1.What idea did Charles Darwin put forward in his book?

A.Giraffe’s necks are 180 cm long and weigh 270 kg on average.

B.Giraffes with a long neck are better at fighting.

C.Giraffes are a species that is born with a long neck.

D.Longer-necked giraffes are able to survive better.

2.What is the article mainly about?

A.Charles Darwin’s theory of evolution.

B.Different functions of the giraffe’s long neck.

C.How the giraffe manages to survive in nature.

D.Theories about why the giraffe has a huge neck.
