Article: Unlike many surfers who sought the perfect wave, my interests always lay beneath the sea' s surface in a world I could only imagine and dream of.When I was twelve, I made my first adventures in the deep.Later I would learn how to dive, expanding my world of exploration many times over. Perhaps the greatest turning point in my life came when I was in high school and I wrote a letter to the famous Scripps Oceanographic Institution, asking how I might learn more about the sea.A kind scientist answered my letter and told me how to apply to Scripps for a summer scholarship, which I received.During one of their courses that summer, I met Dr.Robert Norris, a marine geologist.He loved the sea almost as much as I did.Soon he suggested I consider his school, the University of California, for my study.One year later I became a member of the freshman class. Now my love affair with the sea became a serious endeavor .If I wanted to be an undersea explorer, I needed to learn as much as I could about the laws of the physical world that controlled the environment I wanted to enter.The undersea world is not our natural world.It is unforgiving to those who make mistakes.At its greatest depths the water temperature is near freezing, the pressure is eight tons per square inch, and it is totally dark.It is easy to get lost in such a world.I needed to learn a lot about geography, navigation, geology, biology, and many other things. I decided another important thing for me to do was to join the U.S.Navy.If I was going to be an undersea explorer, I would have to lead men and women on dangerous adventures where they might get hurt, and I didn't want that to happen. In the Navy I learned discipline, organization, and how to motivate and lead people on adventures so that we could explore the wonders of the deep. Finally, the time came to put all that I had learned to use, to go forth with a team of men and women and explore an adventure I am still on and hope to be on for many years to come. Question: What happened to the author at the age of twelve? Options: A: He dreamed about undersea exploration. B: He began to swim under the deep water. C: He surfed on big waves for the first time.

There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry. and the forests there died. Then dinosaurs could not find enough to cat. This must be one reason why dinosaurs died out. We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs. There may be other reasons that we don't know about yet. Scientists are trying to make more discoveries about dinosaurs. Dinosaurs were of many sizes and shapes  .  Some were as small as chickens, while some were about 90 feet long. There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal's footprints   that fight did take place.

Q: Read the article and select the best answer. Article: The NSA  and GCHQ  are tapping popular smart phone apps such as Angry Birds to gather the enormous amounts of very personal data those bits of software collect--including age, gender, marital status, income, education level and more, according to new reports from the New York Times and The Guardian. Citing secret documents provided by Edward Snowden, former NSA staff, the reports detail efforts to gain data collection from cell phone carriers and smart phones by tapping into "leaky"  apps themselves. Both spy agencies showed a particular interest in Google Maps, which is accurate to within a few yards or better in some locations and would clearly pass along data about the area where phone owner is. "It effectively means that anyone using Google Maps on a smartphone is working in support of a GCHQ system," reads a secret 2008 report by the NSA's sister spy agency, according to the New York Times. More surprising is the wide range of apps that the agencies search for data, including innocent-seeming apps such as Angry Birds. One document in particular from GCHQ listed what information can be found from which apps, mentioning Android apps but suggesting the same data was available from the iPhone platform. Angry Birds maker Rovio Entertainment of Finland said it had no knowledge of any NSA or GCHQ programs for tapping into its users' data. "Rovio doesn't have any previous knowledge of this matter, and have not been aware of such activity in 3rd party advertising networks," said Saara Bergstrom. "Nor do we have any involvement with the organizations you mentioned." Mobile photos uploaded to social media sites like Facebook and Twitter appear to be a particularly rich source of information for the spy agencies as well. Metadata in the photos is briefly available. The NSA and GCHQ are able to tap into that metadata to collect a wealth of key data points about a person's life. "NSA does not profile everyday Americans as it carries out its foreign intelligence mission," the agency told the Times in response to...

Q: Read the article and select the best answer. Article: After a particularly busy period at work, I decided to get away from it all by going on a hike in the mountains in southern France. Before I left, I read an interesting story in a magazine. It read, "Once, while I was riding on a crowded bus, the man sitting next to me threw his cell phone out of the window when his phone rang. I was surprised. He looked at me, shrugged   and looked away. I had no idea whether it was his or stolen or whether he even knew what a cell phone was or not, but he clearly wanted to be free of it, because it clearly troubled him. " Billions of people across the world use cell phones. Though cell phones are a wonderful way for communication, they often do the exact opposite. Using cell phones can increase stress within families and friends. So when I recently returned home, I got rid of my cell phone. Now I go outside without taking my phone with me. I've noticed things in my neighborhood I never noticed before, such as gardens. I've met new people, started conversations with neighbors I didn't speak to before and talked with some of my friends face to face instead of chatting over the phone. Instead of keeping me off from the world, stopping using my cell phone has helped me get even closer to my family and friends. Question: According to the story, the man on the bus threw away his cell phone because   _  . Options: A: it didn't work properly B: it was stolen from someone else C: he didn't like the phone's style D: he didn't want to be bothered by it
