Article: SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots.City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think.Now San Francisco has found a solution -- a phone app for spot-seekers that shows information about areas with available spaces.The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. But the system could come with serious consequences.Some people say that drivers searching for parking could end up focusing on their phones, not the road."It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials admitted the hidden problem.They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages.If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency.On the app, a map shows which blocks have lots of places(blue)and which are full(red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone. Question: What is the phone app mentioned in the text mainly aimed at? - Benefiting iPhone users. - Preventing traffic accidents. - Making the traffic flow smoothly. - Making full use of the parking spots.
Making the traffic flow smoothly.

Read the following article and select the best answer. Article: One silly question I simply can't understand is "How do you feel?" Usually the question is asked of a man's action-- a man on the go, walking along the street or busily working at his desk. So what do you expect him to say? He'll probably say," Fine, I'm all right.", but you've put a bug in his ear. ---Maybe now he's not sure. If you have a good friend, you may have seen something in his face, or his walk, that he overlooked that morning. It starts him worrying a little. First thing you know, he looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else. "How do you feel?" Every question has its time and place. It's perfectly acceptable, for example, to ask "How do you feel?" if you're visiting a close friend in hospital. But if the fellow is walking on both legs, hurrying take a train, or sitting at his desk working, it's no time to ask him that silly question. [:Z _ xx _ k.Com] When George Bernard Shaw, the famous writer of plays, was in his eighties, someone asked him, "How do you feel?" Shaw put him in his place.

Read the following article and select the best answer. Article: Legend has it that sometime toward the end of the Civil War (1861 - 1865) a government train carrying oxen was caught in a snowstorm and had to be abandoned. The driver returned the next spring to see what had become of his cargo. Instead of the skeletons he had expected to find, he saw his oxen, living, fat, and healthy. How had they survived? The answer lay in a resource that unknowing Americans had trampled underfoot in their haste to cross the "Great American Desert" to reach lands that sometimes proved barren. In the eastern parts of the United States, the preferred grass for forage was a cultivated plant. It grew well with enough rain, then when cut and stored it would cure and become nourishing hay for winter feed. But in the dry grazing lands of the west, that familiar blue joint grass was often killed by drought. To raise cattle out there seemed risky or even hopeless. Who could imagine a fairy-tale grass that required no rain and somehow made it possible for cattle to feed themselves all winter? But the surprising western wild grasses did just that. They had wonderfully convenient features that made them superior to the cultivated eastern grasses. Variously known as buffalo grass, not only were they immune to drought, but they were actually preserved by the lack of summer and autumn rains. They were not juicy like the cultivated eastern grasses, but had short, hard stems. And they did not need to be cured in a barn, but dried right where they grew on the ground. When they dried in this way, they remained naturally sweet and nourishing through the winter. Cattle left outdoors to fend for themselves thrived on this hay. And the cattle themselves helped plant the fresh grass year after year, for they trampled the natural seeds firmly into the soil to be watered by the melting snows of winter and the occasional rains of spring. The dry summer air cured them much as storing in a barn cured the cultivated grasses. Question: According to the passage, the cattle helped promote the growth of the wild grasses by _ . - stepping on and pressing the seeds into the ground - naturally fertilizing the soil - continually moving from one grazing area to another - eating only small quantities of grass
stepping on and pressing the seeds into the ground
