Read the following article and select the best answer. Article: I am a taxi driver. One Monday morning, I had stopped at New York Hospital when I found _ man dashing down the steps. He was waving to me. I waited until he jumped into the cab. " LaGuardia Airport, please," he said. As always, I wondered about my passenger. " What do you do?" " I am in the neurology department at the hospital." For some unknown reason, I decided to ask for his help. " Could I ask a favor of you?" He didn't answer. " I have a son, 16. He's doing well in school. He wants a job this summer. Is there any possibility that you might get him a summer job?" After a pause, he said, " The medical students have a research project. Maybe he could fit in. Have him send me his school records." He searched his pocket and handed me a card. That evening, I pulled the card from my pocket. " Robbie," I announced proudly, " this could be a summer job for you. Send him your school records." He read it out loud, " Fred Plum, New York Hospital." " Is this a joke?" he said in disbelief. After I shouted and threatened to cut off his pocket-money, Robbie promised to send off his grades the next morning. Two weeks later, when I arrived home, my son handed me a letter from Plum. He was to phone Plum's secretary for an interview. Robbie got the job. The white coat he wore made him feel more important than he really was. As high school graduation neared, Plum was kind enough to write letters of recommendation for universities. To our delight, Robbie was admitted to New York Medical College. It never occurred to me that a stranger should change my son's future. Question: What message does the passage want to tell us? - A stranger may change your life. - One must be friendly to strangers. - A father should be responsible for his son. - Doctors may have a great effect on people.
A stranger may change your life.

Read the following article and select the best answer. Article: Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday. Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa. "Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive species," Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report. The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats. "The remaining populations become surrounded in very small ecosystems, they have inbreeding problems ... and at the end these species may disappear," he added. Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi. The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence. Other consequences could include the spread of invasive species and infectious diseases, it said. The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves , inland waters, forests, savannahs and grasslands. The FAO also called for the creation of migration corridors for animals in areas where their movement was limited. The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed. It also urged local communities... Question: Why are animals living in mountains, islands and coastal areas most affected? - They are frequently attacked by invasive species and infectious diseases. - They have difficulty finding enough food for survival. - They can hardly find mates to produce their young. - They have little chance of moving to other places.
They have little chance of moving to other places.

*Question*
Read the following article and select the best answer. Article: IF you lived by the sea, you'd know that typhoons are frequent visitors during summer .They bring Strong winds, heavy rain and flooding But most of the time, when people stay indoors, they're just all right. This is what the people in the Philippines used to believe - until they met the "super typhoon", Haiyan. The typhoon hit the country on Nov 8, at around 5 am, when most people were still asleep. But being at home didn't keep them safe, since few buildings remained standing once they were hit by wind as violent as 376 kilometers per hour, according to NBC News. "This is at the top end of any tropical system that we've seen on our planet," said Bryan Norcross, a weather scientist working for NBC. And so far, Haiyan has caused more than 3,600 deaths and left millions of people homeless. .But where did Haiyan get its destructive power? According to Brian McNoldy, a tropical weather expert at the University of Miami, US, Haiyan was so strong because "it had everything working for it" "All typhoons feed off the warm ocean waters," Colin Price, a weather researcher at Tel Aviv University in Israel, told National Geographic. Tropical storms are like giant engines ,powered by the heat transferred from the ocean waters to the air above. However, because of climate change, the oceans have been warming up in recent decades. "Warmer oceans will result in more intense storms," Price said. Also, Haiyan started near the equator ,where it was able to pick up more heat before heading to the Philippines. Moreover, the route it traveled was mostly along open ocean, which means no land prevented it from gathering steam . In addition, there happened to be very little "wind shear in the area this time. Wind shear is a sudden change in wind speed or direction, which can tear apart developing storms. This is like when you stir a glass of water with a chopstick: a swirl will form, 'but if you move the chopstick in the opposite direction, the swirl will quickly disappear." "When all those things _ in a certain way, you're going to... Question: Which of the following is TRUE about typhoons according to the article? - They mostly happen early in the morning. - They mostly do damage during winter. - During most typhoons people can keep safe just by staying at home. - This year, more intense storms have happened in the world,
**Answer**
During most typhoons people can keep safe just by staying at home.
