The apple tree may be one of the oldest fruit trees in the world.There is evidence of people eating apples all the way back in the Stone Age.This sweet-tasting,healthy fruit is still a favorite among people everywhere.More than 60 million tons of apples are eaten worldwide each year.
Now there may be good news for apple lovers.Soon they may be even crunchier(香脆) and juicier.Scientists have now mapped the genome of the Golden Delicious apple.A global team of 86 scientists from Italy,France,New Zealand,Belgium,and the US spent two years on the work.Professor Riccardo Velasco in Italy,who led the research team,said that mapping the genome would have a big effect on apple breeding(培育).“This breakthrough will help us to develop high quality traits and bring new things to the apple market,” he told BBC News.
Scientists hope improvements to the popular Golden Delicious apple,which began to grow in the US more than a century ago,could make the fruit look and taste better.The decoding of the apple’s DNA also tells us more about its beginning.The researchers traced the fruit back to Malus sieversii,a wild plant that grew in the mountains of southern Kazakhstan about 4000 years ago.There are more than 7,500 varieties of apple known today.
The team now wants to find more of the apple’s secrets,such as which genes control flavor.Looking through all the information takes time.Scientists turned to some of the apple’s relatives,pears,peaches,and grapes,to help them finish their job.Even though these fruits look and taste different,they share some genes.“Knowing how a gene in a peach works sheds light on how a similar gene may work in an apple,” said Amit Dhingra from Washington State University,one of the researchers.“It also helps us identify what genes are unique to each fruit.”
Which of the following statements is TRUE of apples?

The researchers on the global team are trying to improve the quality of apples by  .

What does the underlined phrase“sheds light on”mean?

Eco-friendly Vauban,Germany,located in the southwest part of the country,is a city where less than 20 percent of the residents own automobiles.Most of the people get around the town by using bicycles and their feet,according to an article (with video) by ABCNews.com.Can an eco-friendly city like Vauban be a model for Americans to stop their over-reliance (过度依赖) on the automobile?
Anytime I watch a news report,what’s often in the back of my mind is what isn’t reported or stressed.While this eco-friendly city is inspiring in that it shows residents getting their exercise and more fresh air through the majority use of bicycles,rollerblades (轮滑鞋),as well as good old-fashioned walking,common sense would tell you that even for a place like Vauban it owes its existence to the automobile.
Do you think that bicycles were able to transport all the construction materials that were needed to build the eco-friendly homes and businesses in Vauban?Were rollerbladers able to move all the materials needed for the sidewalk and bicycle path construction?It took automobiles to help build this place.
I myself haven’t owned a car for more than 14 years.I mostly get around town via running,walking,and use of public transportation.Although I’m glad lots of walking and running has helped to keep me fit and healthier,there are times I wish I had an automobile because it would make things really easier.
In order for America to get even close to being like eco-friendly Vauban,we need to change the way we live,starting with huge investment (投资) in public transportation,etc.Yet ending Americans’ dependence on the automobile will be virtually impossible during my lifetime.At best,one will see more Vauban-like areas in the USA.
It can be hoped that Americans will consider using their feet more to get around when possible,which would cut down on some pollution and provide some health benefits via exercise.

Every year on my birthday, from the time I turned twelve, a white gardenia was delivered to my house. No card or note came with it.     to the flower shop were always useless---it was a cash     . After a while I stopped trying to     who the sender was and just delighted in the beauty and perfume of the white flower. But I never     imagining who the sender might be. Some of my     moments were spent daydreaming about it.
My mother asked me whether there was someone for whom I had done a(n)     kindness who might be showing     . Perhaps the neighbor I helped when she was      a car full of groceries. Or maybe it was the old man     the street whose mail I helped to get during the     so he wouldn’t have to venture down his icy steps. As a teenager,      , I had more fun guessing that it might be a      who had noticed me      I didn’t know him.
One month before my high school graduation, my father died of a heart attack. He was     some of the most important events in my life. I became completely     in my upcoming graduation and the dance.

I didn’t     if I had a new dress or not, but my mother did.
She wanted her children to feel      and lovable, imaginative, believing that there was a magic in the world and        in the face of hard times.
