People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.

In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. “Today we’re looking at science fiction becoming tomorrow's reality-the driverless car. ” The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.

Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. “A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. ” Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don’t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.

“By taking out drivers, you also remove most risks of an accident, ”Kendall said. He said , “Consumers, however, may be unwilling to lose control. It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. ”

Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

A. is for the idea of having driverless cars

B. sponsored the DARPA competition to improve the driverless system

3.In Kendall’s opinion, who probably don’t rely on the driverless cars at first?

A. managers in the high-tech company Google

B. officers from the U. S. government agency DARPA

Researchers are finding new ways to save snakebite victims.Experts discussed the latest findings during a recent conference.

Scientists in Australia have shown that a chemical called nitric oxide could increase the chances of surviving a poisonous snakebite.The scientists injected rats with a deadly amount of snake venom.Then they rubbed an ointment(软膏)containing nitric oxide on the skin around the injection site.The study found that the rats lived about one-third longer than if nitric oxide had not been used.But the treatment had to be started very quickly.

Dirk van Helden led the research.He says the nitric oxide ointment also showed promise in humans.The study appeared earlier this year in the journal Nature Medicine.Scientists say the findings could help save many lives.A recent study found that poisonous snakes cause as many as ninety-four thousand deaths worldwide each year.But Ulrich Kuch of the Biodiversity and Climate Research Center in Frankfurt,Germany,says that number appears to be low.

Mr Kuch says many deaths could be prohibited if snakebite victims are treated correctly,but they often go to traditional healers or do not seek any help at all.He said,“Sometimes it’s because there is no treatment available—no antivenom(抗蛇毒血清),which is the specific(特殊的)drug to treat snakebites—or health care staff do not know how to treat snakebites,and sometimes its because transportation to get to a health facility is not available or too expensive.

Here is no single antivenom that can be used to treat all snakebites.The antivenom must be specific to the kind of snake that bit the person.In some countries the treatment is costly,while in others there is no such treatment.

1.What is this passage mainly about?( )

A.Snakebite deaths around the world.

B.Progress in fighting snakebite deaths.

C.Snakebite treatment around the world.

D.The chances of surviving a poisonous snakebite.

2.After being rubbed an ointment containing nitric oxide,the rats .

A.suffered no pain B.died immediately

C.lived a little longer D.started feeling uncomfortable

3.What does Paragraph 3 suggest?( )

A.The number of deaths caused by snakebites is becoming lower each year.

B.The nitric oxide ointment has saved thousands of people’s lives.

C.It is very important to find an effective way to treat snakebites.

D.The number of deaths caused by snakebites worldwide is low.

4.What does the underlined word “prohibited” in Paragraph 4 mean?( )

A. caused. B.considered.

C.examined. D.prevented.

5.What is implied in the last paragraph?( )

A.Antivenom can be made very easily.

B.It’s very important to use the correct antivenom to treat snakebite victims.

C.Antivenom is extremely expensive all over the world.

D.A person bitten by a snake will survive as long as there is antivenom.

My grandma whom we all called Nanny was a solid, first-generation, Italian immigrant. She came to this country with her family on a tiny ship during World War I when she was only 8 years old. During the trip she survived stormy seas,little food, and an attack by a German U-boat. After getting here,her large family worked hard to build a new life in America. They never had much money but were rich in love.

One day, when I was about 5 or 6 years old, my parents and brothers went on a trip. It was just me and Nanny in the house for the weekend. Nanny seemed so happy to be taking care of me all by herself. She made me a special breakfast that first morning. However, all I could do was to complain about how the food was not how Mom always made it. Nanny quietly put down the plate and went into the living room. I followed a minute later and saw that she had tears in her eyes. It was the first time I had ever seen my strong and proud grandmother cry and I was the one who had caused it.

I walked over to Nanny, climbed on her lap, and for the first time in my short life I did something else too. I apologized without being told to and asked Nanny to forgive me. She smiled, rubbed my head, and told me I was a good boy even though I didn't feel like one then.

That memory just like my Nanny's love will stay in my heart forever. It is a sign of both strength and wisdom. Asking for forgiveness helps us to learn, to grow, and to love.
