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: What causes tremors and quakes according to the passage? Yes or no, is the answer "The effect of the gravitational tug of sun and moon on Earth's crust."?
Yes

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: The "do-it-yourself" movement originated in _ . Yes or no, is the answer "house decorating"?
(Answer)
No

Question: Article: As an English teacher, one of the most common problems I've found with my students is their lack of confidence with speaking, and difficulty in understanding native speakers. Another problem could be that a foreign language taught in schools can sound quite different to what native speakers actually use. There are a few English words and expressions that I'd never heard until I came to China. The most common one in my experience is "How are you? I'm fine, thank you, and you?" I appreciate that although this greeting is much too formal for everyday use - it's easy to learn and helps build confidence. However, it can be a hard habit to break. I've seen many parents correct their kids if they don't use that exact phrase, as if simply replying "I'm fine" would somehow be rude. In fact I'm banning my students from saying that in the classroom, insisting a simple "I'm fine, thanks" is good enough. "Seldom" is another one that I find interesting. The first time a student told me "I seldom watch TV", my initial reaction was a stupefied look, followed by "Huh?" I then realized the student used "seldom" when it's more common for us to use "rarely." I was just as confused when I first heard a toilet referred to as a WC (water closet), another English term I'd never heard of back in Australia. Of course, my students know the other names for it like bathroom, toilet, washroom etc. so to prefer that name is an interesting choice. I don't mind that my students have substituted familiar English words with their own, far from it. It reminds me how creative they can be with not only their language, but with mine as well. It's healthy for English to evolve and change and I'm happy to add these new words to my vocabulary. One important lesson I've learnt is that textbooks can only help you so much. For further improvement you'd better practice with native speakers. Question: What is the writer's attitude towards his students using Chinese-English? Yes or no, is the answer "He's tolerant."?
Answer:
No
