Article: Contrary to people's previous knowledge, it's food shortage not dietary preference that motivates birds to migrate thousands of miles back and forth between breeding and nonbreeding areas each year, a new research shows. "It's not whether you eat insects,fruits or candy bars or where you eat them that counts,but how reliable that daytoday food source is," said the study leader W.Alice Boyle of the University of Arizona. To figure out the underlying pressure that drives some birds to leave home for the season,Boyle examined 379 related species of New World flycatchers  and compared their sizes,food types, habitats, migratory behaviors and whether or not they fed in flocks. To compare the birds,the researchers constructed a "supertree"  showing the exact evolutionary relationships among different species. A computer analysis then determined whether a particular species was migratory because it ran in the "family" or whether something in the bird's environment was forcing it to leave each season.Boyle and her colleagues found that food shortage was the number one issue that predicted a species' migratory behavior. "Food availability is the underlying pressure, not diet and habitat," Boyle said. An alternative strategy that the birds use to handle food shortage is to hunt in flocks, since a group is more likely to find a new source of food than an individual. "If you suffer from food shortage, you have two options," Boyle said."You can either hunt with other birds or you can migrate." Question: Birds were thought to migrate in order to   _  . Options: A: seek their favorite food in a new place B: avoid being constantly hunted C: breed more young in a new place D: adjust themselves to the changes of weather

Ques: Read the article and select the best answer. Article: Washington----A screaming intruder  made it onto the front lawn of the White House Sunday while President Obama was at home before being caught by Secret Service officers. Secret Service spokesman Eric Zahren recognized the man as 40-year-old Brian Lee Patterson, whose last known address was in Albuquerque, N.M. Patterson has been caught trying to get onto the White House grounds at least three times before Zahren said. The bearded man, wearing blue jeans and a white T-shirt that read "God Bless America" jumped the fence outside the White House and ran across the north lawn while repeatedly crying, "I am a victim of terrorism!" Members of the Secret Service emergency response team, including one holding a barking dog, ran after Patterson with their guns and surrounded him near the row of cameras set up for television stand-ups. "I have intelligence information for the president," he said, waving his arms in the air. "I'm not afraid of you." Patterson screamed at the officers who were ordering him to lie ground with guns drawn. Patterson finally kneeled on the ground and was taken into custody  shortly before 4 p.m. He cut his hand jumping the fence and was taken to George Washington University Hospital for treatment and was to appear in court Monday, Zahren said. Zahren said Patterson was charged with unlawful entry for the last time he jumped the fence, in February. He faces the same charge for Sunday's incident and also a contempt  of court charge for disobeying the judge's orders to stay away from the White House. Question: Entering the White House, Patterson meant   _  . Options: A: to kick against the law B: to fight against the Secret Service officers C: to see the president D: to have a look around the White House
Ans: C
Ques:Read the article and select the best answer. Article: Healthy people with stressful jobs who work long hours but get little satisfaction from what they do have twice the risk of dying from heart disease as satisfied employees, according to a study. Job stress has been known to cause heart problems in people who already have cardiovascular disease  . Finnish scientists have now shown that even in healthy people the pressures of work can take their toll. High blood pressure, lack of exercise, smoking and being overweight contribute to heart disease--a leading killer in many industrialized countries. But Mika Kivimaki, of the Finnish Institute of Occupational Health, and his colleagues, who studied the medical histories of 812 healthy Finnish men and women in a metal industry company over 25 years, said job stress also plays an important role. Workers who had the highest job-related stress levels at the start of the study were more than twice as likely to die of heart disease, according to the study published in The British Medical Journal. Work stress involves too much work as well as a lack of satisfaction and feeling undervalued and unappreciated. Many people work long hours but if the effort is rewarding the stress is _  The British Heart Foundation said the results support earlier research showing that people in jobs with low control, such as manual  workers, could be as great risk of heart disease than other employees. " It is advisable for people to try to minimize levels of stress at work and for employees to allow people to have more control at work and to be rewarded for their successes," the foundation said in a statement. Question: Healthy people may die from heart disease of   _  . Options: A: too much job stress B: working too hard C: feeling valued D: being satisfied
