user: I'm taking a test and have to guess the right answer to the question after the article. Article: A new study suggests that the way to weight loss may be clear.A couple of glasses of water before meals help dieters lose about 5 pounds more than those who do not drink water.While drinking water before a meal may fill a person up,the contents of their meal are important as well.Should a person be eating a low-fat diet or a lowcarbohydrate   diet? Or does it matter at all? Recent research suggests that one diet isn't any better than the other.A few weeks before the water study,another concluded that lowfat and lowcarbohydrate diets tied in weight loss.While the lowcarbohydrate dieters did show a slight increase in good cholesterol   and a reduction in blood pressure,there was not much difference in the dieters'weight loss.The point here is that the person had to stick to the diet.What helps a person see a diet through? It could be body type. A study published in the Journal of the American Medical Association,as reported byTimemagazine,found that body shape is the key to which diet a person will be able to stick with.Apples are people who carry most of their weight above the belt,while pears carry their weight around their hips  .Apple types were more likely to be highinsulin secretors   who respond more strongly to carbohydrates in their bodies.They lost the most weight on a lowcarbohydrate diet.Pears were lowinsulin secretors who lost the same amount of weight on both diets.Unstable   insulin levels can create stronger hunger senses,causing the apple types to go off their diet plans. All of these studies again come down to choosing the diet that helps you eat less.The bodytype diet does make some sense as men are more likely to be apple types,with larger stomachs,and tend to do well on higherprotein diets,while women,who tend to carry weight around their hips,find themselves drawn to the lowfat diets.The reality is if a diet is failing you try another one.A plan you can't,or won't,stick to will never work,no matter what the research says. Question: If you want to lose weight but don't know what diet suits you,you can always   _  . Options: A: drink a few cups of water after each meal B: drink a few cups of water before each meal C: eat plenty of pears D: eat plenty of apples

I'm taking a test and have to guess the right answer to the question after the article. Article: You always have to understand what you are good at, and what you are not good at. Or if you are interested in something you always have to master it first. When I was ten, I came over to my cousin's house, and that was pain because he lived in New York and I lived in Miami. So I came over every summer break by myself, of course I had my parents' permission to go that far. One day, We decided to head to the forest. I was looking forward to this trip because I knew that my cousin was an expert on tree climbing while I was not. So, as we walked closer and closer to the forest, I became _ because I did not possess the ability to climb trees. When he started climbing a tree I was upset but I joined him hoping not to break my neck. Last Summer break he invited me to his house. I was afraid of climbing to the tree so I gave up. But this time I tried climbing the tree. While I was climbing I was so scared like I was about to die at any moment. But when I was about to climb on the other branch I lost my balance. Luckily I got hold on one of the bottom branches.  My cousin suddenly started climbing down and tried to help me. After he put me on the ground, he ran to get some help. The pain was just killing me, I lost a lot of blood and I knew that I have to be awake to survive. Finally, my cousin brought the help. When I waked up I was happy that I did not die. It was pretty insane what happened to me. ( 295 words ) Question: We can learn from the passage that   _  . Options: A: The author would learn how to climb the tree after recovering. B: You can do anything well if you are interested in it. C: You should know yourself well first and do what you can. D: The author could go out without his parents' permission.

I'm taking a test and have to guess the right answer to the question after the article. Article: The secret of carrier pigeons' unbelievable ability to find their way home has been discovered by scientists: _ follow the roads just like we do. Scientists now believe the phrase "as the crow   flies" no longer means the shortest most direct route between two points. They say it is likely that crows and other day birds also choose AA-suggested routes, even though it makes their journeys longer. Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions. Instead they fly along motorways, turn at crossing and even go around roundabouts   , adding miles to their journeys. "It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts   and follow the road system," said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology. Guilford said pigeons use their own navigational system   when doing long distance trips or when a bird does a journey for the first time. "But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work," said Guilford. "In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journey as simple as possible." Question: Scientists used to think that homing pigeons often find their directions   _  . Options: A: by global positioning satellite B: by the sun C: by the road system D: by following other birds
