Earth system science involves observation and measurements on the Earth at all scales from the largest to the smallest. The huge amounts of data that are gathered come from many different locations and require special techniques for handling data. Important new tools that facilitate Earth system science include satellite remote sensing, small deep-sea submarines, and geographic information systems. More than any other way of gathering evidence, satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts. Earth system science was born from the realization of that interdependence. Satellite remote sensing makes possible observations at large scales, and in many cases, measurements of factors that could not otherwise be measured. For example, the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing, as are changes in deserts, forests, and farmlands around the world. Such measurements can be used in many areas of specialization besides Earth system science. Archaeology, for example, has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert. New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system. Small deep-sea submarines allow scientists to travel to the depths of the ocean. There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat, sasses, and mineral-rich water. Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system. Computer-based software programs known as geographic information systems, or GIS, allow a large number of data points to be stored along with their locations. These can be used to produce maps and to compare different sets of... Question: According to the passage, satellite observations of the Arabian Desert allow archaeologists to know _ . Options: A: indications of ancient routes B: evidence of former lakes C: traces of early farms D: remains of ancient forests

Article: It's a nightmare for Huazhong University of Science and Technology (HUST): within a week, two students committed suicide by jumping off dorm buildings. Officials from the university are reluctant to give interviews. "We had a hard time calming down students who were shocked at the suicides," said Zhang Jingyuan, head of HUST's center for research and guidance for students' development. "Media coverage may arouse some students' negative emotions again. Suicide can be contagious ," Zhang said. The university reacted promptly to the first suicide on October 23. Advisors and class leaders conducted dorm-to-dorm checks to find students suffering depression. Then psychologists offered one-on-one counseling to them. Notice boards publicizing tips for identifying peers' mental problems and offering help were set up in front of dorm buildings. Leaflets carrying similar information were handed out to each dorm. However, the second suicide came seven days later. Both students were described as men of few words. Their schoolmates didn't see anything to indicate suicide. Zhang revealed that the two students had been bothered by mental disorders. But the school didn't know this until the students' close friends outside school and their parents unveiled the truth after the suicides. According to Zhang, there are only three full-time counselors working in the university's counseling center for its 60,000 students. He complained: "It's unrealistic to rely only on counselors to detect students' mental problems." Some universities in the US may be able to offer solutions to Zhang's worries. They have established programs to train students to be the bridge between troubled friends and counselors. At Worcester Polytechnic Institute, at Worcester, Massachusetts, US, young people in the Student Support Network role play to learn how to detect SOS signals from their schoolmates. They also practice how to gently persuade emotionally troubled students to go for professional help. To develop such empathy , many universities in...

Mrs Smith's dog was hungry, but there was not any meat in the house.Considering that there was no better way, Mrs. Smith took a piece of paper, and wrote the following words on it "Give my dog half a pound of meat. " Then she gave the paper to her dog and said gently:" Take this to the butcher and he's going to give you your lunch today." Holding the piece of paper in its mouth, the dog ran to the butcher's. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady's handwriting and soon did it as he was asked to. The dog was very happy, and ate the meat up at once. At sunset, the dog came to the shop again. It gave the butcher a piece of paper again. After reading it. he gave it half a pound of meat once more. The next day, the dog came again exactly at noon. And as usual, it brought a piece of paper in the mouth. This time, the butcher did not take a look at paper, and gave the dog its meat, for he had regarded the dog as one of his regular customers . However, the dog came again at four o'clock. And the same thing happened once again. At six o'clock,, it came for more meat, and brought with it a third piece of paper. The butcher felt a bit puzzled. He said to himself, "This is a small dog. Why does Mrs Smith feed it with so much meat today?" Looking at the piece of paper, he found that there was a piece of blank paper. He laughed and phoned Mrs Smith.
