Article: A new study revealed that the formation of the Earth, Sun and Moon that cause changes in Earth's tides can also trigger a special kind of Earthquake along the California's San Andreas Fault . The study, published in the journal Proceedings of the National Academy of Science,is based on previous researcher suggesting that the gravitational tug of sun and moon is not only affecting the sea levels of Earth, but can also stretch and compress that Earth's crust, producing tremors and quakes. Furthermore, the new study showed that small tremors deep underground were more likely to occur during certain periods of the tidal cycle. For the study, the researchers looked at about 81,000 low-frequency earthquakes from 2008 to 2015 along the Parkfield section of the San Andreas Fault and compared it to the two-week tidal cycle known as the "fortnightly tide," Low-frequency earthquakes are named due to the rumbling sound they make and not by the rate of its occurrence. These kinds of earthquake only occur about 15 to 30 kilometers below ground and are no larger than magnitude 1 in the Richter scale. The researchers discovered that low-frequency earthquakes tend to occur during the waxing period of the tidal cycle, when the tides are getting little by little. It is already known that the strongest Earth tides occur when the sun and moon are in a straight line, while the tide is at its weakest state when the sun and moon are 90 degrees apart. According to the researchers, low-frequency earthquakes show that some part of the San Andreas Fault is creeping, or slowly moving, almost all the time. With the help of the tidal forces, low-frequency earthquakes could provide more information about the deeper part of the fault. "They tell us that the fault continues down below where the regular or typical earthquakes stop on the San Andreas, about 10 or 12 km (about 6 to 7 miles)," said David Shelly, a seismologist at USGS and helped write the study, in a statement. "And they tell us a lot of things about that deep part of the fault... Question: Low-frequency earthquakes occur when _ . Options: A: the tides are getting bigger gradually B: the sun and moon are in a straight line C: the sun and moon are 90 degrees apart D: the San Andreas Fault moves slowly

Read the article and select the best answer. Article: Some people would say that the Englishman's home is no longer his castle; that it has become his workshop. This is partly because the average Englishman is keen on working with his own hands and partly because he feels, for one reason or another, that he must do for himself many households for which, some years ago, he would have hired professional help. The main reason for this is a financial one. The high cost of labor has meant that builders' and decorators' cost have reached a level which makes them prohibitive for house-proud English-people of modest means. So, if they wish to keep their houses looking bright and smart, they have to tackle some of the repairs and decorating themselves. As a result, there has grown up in the post-war years what is sometimes referred to as the "do-it-yourself movement". The "do-it-yourself movement" began with home decorating but has spread into a much wider field. Nowadays there seem to be very few things that can't be made by the "do-it-yourself movement" method. A number of magazines and handbooks exist to show hopeful handymen of all ages just how easy it is to build anything from a coffee table to a fifteen-foot sailing boat. All you need, it seems, is a hammer and a few nails. You follow the simple instructions step by step and, before you know where you are, the finished article stands before you, completely in every detail. Unfortunately, alas, it is not always quite as simple as it sounds! Many a budding "do-it-yourself" has found to his cost that one can not learn a skilled craftsman's job overnight. How quickly one realizes, when doing it oneself, that a job which takes a skilled man an hour or so to complete takes an amateur handyman five or six at least. And then there is the question of tools. The first thing the amateur learns is that he must have the right tools for the job. But tools cost money. _ It is not surprising then that many people have come to the conclusion that the expense of the paying professional to do the work is, in the long run, more... Question: According to the passage we know that some Englishmen prefer hiring professional decorators NOT because _ . Options: A: they are very wealthy B: the craftsman's job is quite complicated C: the tools are expensive D: "do-it-yourself" brings a lot of troubles

A

Question: Read the article and select the best answer. Article: The US government has started a website, Admongo, to help children think critically about the advertising aimed at them. It claims to provide visitors with an "education" through games and other amusement. A cartoon man dressed in old time pilot clothing greets visitors to Admongo. "Call me Haiz", he says upon arrival in a rocket ship that opens up with a crazy world inside it. Spacey dance music plays in the background as Haiz tells visitors that they need to learn about advertising. Its inventors say eight to twelve years old is the age kids develop their critical thinking abilities. Kids that age are also a big market for advertisers. The idea behind Admongo is to teach children three things: To _ the advertiser. To know what the advertiser is really saying. And to know what the advertisement is trying to get the child to do. Children learn these things through a video game. They create their own game character. They can choose different skin colors, hair styles, eye and mouth shapes. Then they begin a trip through ad-land, where there are ads on buses and billboards. The players have to find all the marketing in the neighborhood before they can move on to the next level. The Admongo game takes players inside a home, to the advertising studio and everywhere else ads can be found. It is a complete exploration of the world of marketing. One such area is food marketing. The Federal Trade Commission (FTC) says it is a big business. The FTC estimates that food, drink and fast-food restaurants spent more than one and a half billion dollars on advertising to young people in 2010. The FTC says children are important for three reasons. They buy products. They influence parents and caregivers to buy. And they are the future adult buyers of the products. A recent study says most advertising aimed at children is for foods of the lowest nutritional value. First Lady Michelle Obama has said she would like to see advertisers marketing healthy foods for children. Question: What is the best title of the text? Options: A: The guide of Admongo B: An education website for children C: A popular online video game D: A website aimed at children
