1 . Where does the conversation probably take place?

A．At a bank.

B．On a bus.

C．In a taxi.

2 . Maybe in the near future, driverless cars may become common on the roads. Driverless cars have already been test-driven thousands of miles.     1     For instance, it helps reduce the number of accidents and traffic jams.

    2     That is because there are many issues that must be solved before the widespread use of them. One problem is that a driverless car cannot predict problems far down the road like a driver can. The driverless cars react to an emergency only when it actually occurs. For instance, a driver starts to slow down when he sees a child riding her skateboard directly into the road 0.2 km away.     3    

Driverless cars are not suitable for extreme weather conditions.     4     They don't predict or "feel" that the roads have become icy like an experienced driver would. For instance, when a road is icy, a human driver would step on the brakes more gently than when the roads are clean and dry.

Another issue is that driverless cars have maps programmed into their memory, but these maps aren't always updated and accurate. New roads are built, and old roads are closed down.     5     Perhaps one day, driverless cars will be everywhere, but we are not ready for that just yet.

A．The safety problems have almost been addressed.

B．However, they are not yet available for the public.

C．Many advantages can be associated to the driverless cars.

D．Driverless vehicles also have trouble adjusting to new roads.

E．They may become confused by fog, heavy rain, or heavy snow.

F．Due to this, a driverless car may get passenger to the wrong destination.

G．But the driverless car only takes action when the child is in its immediate path.

3 . 第三部分：阅读理解（共20题；
阅读下列短文，从每题中所给的A、B、C、D四个选项中，选出最佳选项。
You have heard the expression “horse sense”. As you may imagine, it came from the time when the majority of people traveled in vehicles drawn by horses. A horse does have a lot of common sense, and there are many true stories about horses having saved their drivers from danger of death.
Today for the most part, people travel by train, ship, airplane, and car, but very little by the use of horses. Modern vehicles are propelled by engines, and an engine does not have any sense. In case of danger, many horses could be depended on to help. Not so with the engine; the driver must do all the things.
In recent years, the speed of travel has increased greatly. With the increased speed comes greatly increased danger. The driver of a powerful engine needs to be careful. A moment of being careless may cost a life. In order to drive today, a person must be able to see clearly, and he must learn and follow carefully the rules for safety on the road. Greater attention is the price we pay for using a machine instead of a horse.
