I'm taking a test and have to guess the right answer to the question after the article. Article: All across California, honeybees are flying away from their hives and dying. Empty hives are causing a lot of worry about some important food crops. Bees give us a lot more than delicious honey. They are pollinators --they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next. The wind pollinates oats, corn, and wheat, but many other plants (like apple and cherry trees and melon vines) depend on insects, bats, and birds. In the U.S., millions and millions of bees kept by human beekeepers fly around doing a lot of this important work for food crops. "Bees are worth protecting because their work adds so much to our diet," says Dr. Jeff Pettis of the Bee Research Laboratory. California's almond crop alone depends on about half the bees in the country. But now the almond crop and many others could be in trouble with so many bees dying. Researchers at government and university labs all over the country are trying to figure out why so many bees are dying. However, bees are hard to study. Most die away from the hive, so researchers don't have dead bodies to examine. And when researchers return to a hive after two weeks, about half the bees they studied on their first visit will be dead, replaced by new ones in the natural life cycle of bees. "It isn't like studying a large animal like a cow that doesn't move around much and is easy to find out in the cow field," says Pettis. Researchers have some ideas about what could be affecting bee health. They could be sick from poisons widely used to kill insects, or they might not be getting enough good food to stay strong. Also, tiny insects called mites feed on bees. "A virus or bacteria could also be doing the killing." explains Pettis. Question: Bees are hard to study because _ . Options: A: they move around too much B: new bees soon replace all the bees studied by researchers C: they are too tiny D: they never return to hives

I'm taking a test and have to guess the right answer to the question after the article. Article: Every year mobile phones develop. Imagining what they will look like and be able to do in 2020 is really a challenge. To help, experts have outlined three major mobile trends that they believe will have become reality by then. Our phones will be so smart in 10 years' time that they'll know everything about our situation and warn us when something needs our attention. This is the top prediction of both Nokia and Google. They predict that our cars and home appliances will be able to communicate with our mobile. For example, fridges will tell your mobile to tell you to pick up milk on the way back from work. While driving, your mobile will suggest that you take a different route because there's a road accident up ahead. The second trend is in gesture-based controls. People who know the iPhone's touch-sensitive screen are already familiar with the technology. It translates hand movements into actions on-screen. But gestural communications will make the phone more convenient to use and may completely replace touchpads. According to industry insiders, the most immediate step forward in gestural technology will be in voice recognition. It's believed voice recognition technology will speed up communications. It is quicker to speak than type. Eventually, phone screens will disappear. The third major development will change our understanding of a mobile phone. From a single phone, the mobile will be developed into multi-part devices. It is opposite to the current trend in which mobile phones are combining the functions of cameras, music players and game consoles. The prediction is based on the idea that the world will become more wireless and all these--cameras, music players and game consoles--will be wirelessly connected. Mobile phones won't need to contain these devices because users will be able to control them wirelessly through their phones. Question: From the text, we can learn that the future mobile phones will _ . Options: A: drive cars for us B: be controlled by the users' voices C: be controlled by home appliances D: be very big together with separated multiple parts
(Answer)
B

I'm taking a test and have to guess the right answer to the question after the article. Article: When I was 11, I had an enemy, a girl who liked to point out my shortcomings . Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. In the end, I became so angry that I ran to my father with tears in my eyes. He listened to me quietly, then he asked. "Are the things she says true or not? Janet, didn't you ever wonder what you're really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said." I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could--and suddenly I wanted to change. For the first time I go to fairly clear picture of myself. I brought the list back to Dad. He refused to take it." That's just for you," he said. "You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do." Daddy's advice has returned to me at many important moments. In my life, I'veneverhadabetterpieceofadvice. Question: Which do you think would be the best title for this passage?
