Tens of thousands of smartphone applications are running ads from the overwhelming advertising networks that change smartphone settings and copy people's contact information without permission. Aggressive ad networks can disguise ads as text message notifications , and sometimes change browser settings and bookmarks. Often, the ads will upload your contacts list to the ad network's servers--- information that the ad network can then sell to marketers. Sounds scary? It's not a giant problem yet, but it's a growing one. As many as 5% of free mobile apps use an "aggressive" ad network to make money, according to Lookout, a San Francisco-based mobile security company. PhoneLiving was one of the most popular app developers to use these kinds of ad networks; their dozens of talking animal apps have been downloaded several million times. Later, PhoneLiving says it has mended its ways. The company admittedusing _ techniques to make money from its apps, but said it dropped those methods at the start of July because of bad reviews and declining downloads. The most popular type of apps that use aggressive ad networks are "Personalisation" apps, which include wallpapers. Comic and entertainment apps are also among the most likely to have rogue ad networks running behind the scenes. Like aggressive pop-ups on PCs, the bad software isn't easy to get rid of. Though the damage can typically be removed by deleting the app, it can be hard to tell which app is causing the problems. When developers create free mobile apps, they usually make money through ads displayed within the app. App makers don't usually tell people which ad network they are using, which makes it hard to avoid the known offenders. The best defense is to read reviews and avoid downloading apps that have attracted many complaints. What do we know about PhoneLiving? A) Its operation model is against the will of netizens. B) It was forced to admit its bad behavior. C) It has changed its business model rapidly. D) Its relationship with Lookout may break up.

Parents say that honesty is the best policy, but they regularly lie to their children as a way of influencing their behavior and emotions, finds new research from the University of Toronto and the University of California. Surprisingly little has been published on the subject of parental lying, so Gail Heyman, professor of psychology at the University of California, Diem Luu, a former student of the University of California, and Kang Lee, professor at the University Toronto, set out to explore the under - researched phenomenon.They asked US participants in two related studies about parents lying to their children - either for the purpose of promoting appropriate behavior or to make them happy. In one of the studies, many parents reported they told their young children that bad things would happen if they didn't go to bed or eat what they were supposed to.Other parents reported inventing magical creatures.One explained, "We told our daughter that if she wrapped up all her pacifiers like gifts, the fair would come and give them to the children who needed them." In the other study, the researchers surveyed college students'recollections about their parents'lying and obtained similar results: parents often lie to their children even as they tell them that lying is unacceptable. The researchers refer to this practice as "parenting by lying"."We are surprised by how often parenting by lying takes place," said LEE.Though Heyman thinks that there are occasions when it is appropriate to be less than truthful with a child, she urges parents to think through the issues and consider alternatives before using lies." Children sometimes behave in ways that are disruptive or are likely to harm their long - term interests," said Heyman."It is common for them to try out a range of strategies, including lying, to stop them.However, parents should be concerned about the possible long - term negative consequences tochildren's beliefs about honesty." The subject of parental lying _ . A) was not allowed to be researched in the past B) attracts little attention because it is common C) hasn't got many published results about it D) is becoming more and more popular

Q: In October 1961 at Crowley Field in Cincinnati Ohio an old deaf gentleman named William E. Hoy stood up to throw the first ball of the World Series. Most people at Crowley Field on that day probably did not remember Hoy because he had retired from professional baseball 58 years earlier in 1903. However he had been an outstanding player and the deaf people still talk about him and his years in baseball. William E. Hoy was born in Houckstown Ohio on May 23, 1862. He became deaf when he was two years old. He attended the Columbus Ohio School for the deaf. After graduation he started playing baseball while working as a shoemaker. Hoy began playing professional baseball in 1886 for Oshkosh(Wisconsin) of the Northwestern League. In 1888 he started as an outfielder with the old Washington Senators. His small figure and speed made him an outstanding base runner. He was very good at stealing bases during his career. In the 1888 major league season he stole 82 bases. He was also the Senators' leading hitter in 1888. Hoy was clever and he threw right-handed and batted left-handed. On June 19,1889 he threw out three batters at the plate from his outfield position. The arm signals used by judges today to show balls and strikes began because of Hoy. The judge lifted his right arm to show that the pitch was a strike and his left arm to signal that it was a ball. For many years people talked about Hoy's last ball game in 1903. He was playing for Los Angeles of the Pacific Coast Winter League. It was a memorable game because Hoy hit a wonderful ball which won the game. It was a very foggy day and therefore very hard to see the ball. In the ninth inning with two men out, Hoy managed to catch a fly ball to make the third out in spite of the fog. Los Angeles defeated their opposition and won the game. After he retired Hoy stayed busy. He ran a dairy farm near Cincinnati for 20 years. He also became a public speaker and traveled giving speeches. Until a few years before his death he took 4-10 mile walks several mornings a... What can be inferred from this passage? A) Hoy was the greatest baseball player in his time. B) Speaking and listening are not necessary in baseball games. C) The judge had to study the hand signals very seriously. D) Hoy's family encouraged him to become a baseball player.

Q: What is the color1 of the universe? Astronomers had not answered this question, until two months ago. That is when two American astronomers reported on their study of all the light in the universe. They said that the universe would appear to the human eye to be a light greenish color1, called turquoise . Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their finding in January. They presented the research at a meeting of the American Astronomical Society. They said that finding the color1 of the universe was not part of their serious scientific research. They did it for fun. However, earlier this month, the scientists admitted to making a mistake. They said their finding was much more color1ful than it should have been. They now say the light from our universe is closer to white. It is more like a milky or creamy white color1. Their study attempted to show what people might see if they could observe the universe from far away. The scientists found the average color1 by combining light from about two-hundred-thousand star systems. Their information came from an observatory in New South Wales, Australia. These scientists and color1 engineers attempted to reproduce the result. Mark Fairchild of the Rochester Institute of Technology in New York was the first person to identify a mistake. He discovered a mistake in the computer software program used by the Johns Hopkins scientists. When the mistake was corrected, the results changed. The new color1 of the universe is much less color1ful. It is very close to white. The scientists have apologized for the mistake. They are now working with the Rochester Institute of Technology to produce more images of the color1 of the universe. They also asked for suggestions for a name for the new color1 of the universe. The best title of the passage should be _ . A) Research made by two astronauts B) The color1 of the universe C) Mistakes made by scientists D) A mistake in the computer
