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.

All across California, honeybees are flying away from their hives(蜂箱) and dying. Empty hives are causing a lot of worry about some important food crops.

Bees give us a lot more than delicious honey. They are pollinators（授粉者）—they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next. The wind pollinates oats, corn, and wheat, but many other plants (like apple and cherry trees and melon vines) depend on insects, bats, and birds. In the U.S., millions and millions of bees kept by human beekeepers fly around doing a lot of this important work for food crops. “Bees are worth protecting because their work adds so much to our diet,” says Dr. Jeff Pettis of the Bee Research Laboratory.

California’s almond (杏仁) crop alone depends on about half the bees in the country. But now the almond crop and many others could be in trouble with so many bees dying.

Researchers at government and university labs all over the country are trying to figure out why so many bees are dying. However, bees are hard to study. Most die away from the hive, so researchers don’t have dead bodies to examine. And when researchers return to a hive after two weeks, about half the bees they studied on their first visit will be dead, replaced by new ones in the natural life cycle of bees. “It isn’t like studying a large animal like a cow that doesn’t move around much and is easy to find out in the cow field,” says Pettis.

Researchers have some ideas about what could be affecting bee health. They could be sick from poisons widely used to kill insects, or they might not be getting enough good food to stay strong. Also, tiny insects called mites feed on bees. “A virus or bacteria could also be doing the killing.” explains Pettis.

1.What is Paragraph 2 mainly about?

A. The wind helps pollinate.

B. Bees are important in food crops.

C. Bees give us a lot of delicious honey.

D. Cherry trees are pollinated by bees.

2.Bees are hard to study because ____________.

A. they move around too much

B. new bees soon replace all the bees studied by researchers

C. they are too tiny

D. they never return to hives

3.What could cause so many bees to die?

A. Poisons to kill birds.                                                               B. Eating too much.

C. Large insects.                                                                          D. Some virus.

4.What can we learn from the article?

A. A large number of bees have died in the hive.

B. Without bees, some foods would disappear from our diet.

C. Only researchers in California want to know what kills bees.

D. Large animals are easier to study than tiny insects.

根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項，選項中有兩項為多 余選項。（如果所用的答題卡沒有E、F、G選項，則選E涂A、B，選F涂A、C，選G 涂A、D。）

Ryan Howes, a clinical psychologist from California, says "Forgiveness is a sensitive act that can feel like it opens us up to more pain． But we need to have a way to process and let go of the effects of injury, or we risk serious physical and emotional consequences．"

People who forgive tend to have better relationships, feel happier and more optimistic, and overall, enjoy better psychological well-being．   1.   It's a difficult process．

There's no single guidebook for forgiveness, though several experts sell their own methods．

Howes suggests focusing on four elements:

Express the emotion． Let yourself feel hurt and angry． Express it to the person who made you feel that way．   2.   Write a letter; you don't need to send it． Shout your emotions at the top of your lungs while you're in the car, alone, with the windows down．

__3.  We want explanations ?even if we don't agree with them． "Was it a misunderstanding? Were you mad at me? Some sort of cognitive framework （認知框架） is necessary, even if you don't like the reason．"

Rebuild safety．4.   That might mean an apology, reassurance from the person in question, distance or stronger boundaries．

Let go． Perhaps it's the hardest part: making a conscious decision not to hold a grudge （怨恨）．

If you're in a relationship, this means not bringing up past wrongs． By letting go, you give up

your role as the victim and become equals again．   5.

A．Otherwise, talk to a friend or even an empty chair

B．Control your feelings

C．Understand why

D．Before you forgive, you need to feel reasonably sure that the act won't reoccur

E．Still, no one ever said forgiveness was easy

F．It's a promise to yourself to stop feeling hurt and to fully move on

G．You may feel helpless, or like life is meaningless

Marriages improve after children grow up and move out，according to an academic study, which suggests an “empty nest” is not always a bad thing.

Popular wisdom has it that parents’ relationships may suffer once their young fly the coop, because they feel they have lost their purpose in life.However, a new study by researchers at the University of California, Berkeley, has found that many couples actually feel happier when their children leave home because they are able to enjoy spending time together.

In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate their satisfaction levels shortly after marrying, when they were bringing up babies, once their children reached their teenage years and finally at age 61, when almost all had “empty nests”．

Although not all said they were happier in general, most claimed their marriages had improved since their children had left home. Researchers believe this is not just because the spouses were spending more time together, but because they were able to enjoy each other’s company more.

One of the participants in the study，which is published in the journal Psychological Science，said：“Once the kids grow up...there’s some of that stress removed...that responsibility removed，so things are a little more relaxed.”

Psychologist Sara Gorchoff，who carried out the investigation，said: “The take­home message for couples with young children is ‘hang in there’．” Her co­author Oliver John added：“Don’t wait until your kids leave home to schedule quality time with your partner.”

However, Dr Dorothy Rowe，from the British Psychological Society，said the effects of living in an “empty nest” will depend on the parents’ relationship with their children.“If you’re just waiting for them to leave home so you can get on with your life，then of course you’ll be pleased to see them go,” she said, “But if you’ve built your life around your children you’ll be terribly lonely.For some parents，their world falls apart when their children leave.”

A．marriages improve after children leave home
