set 1 As is shown in the picture, a librarian is telling a boy that the book named ”How to Do Well in School Without Studying” is in the fiction section, which suggests that there is no shortcut to learning. From my prospective, I do agree with what the picture implies that there is no shortcut to learning. Learning is just like building a house and you are supposed to be whole-hearted when you build it first. More hard-working you are, more stronger the foundation will be. However if you work casually at the beginning, the house is actually in danger and at the risk of collapsing. Plenty of aged-old sayings about studying are not far to seek ,from which we can learn that there is no free lunch in studying as well. Though the technology develops rapidly in today’s world,”knowledge capsules” is non-existent but a ridiculous fantasy in science fiction just like the given picture. There is no better instance than language learning ,which requires lots of time and energy spent on alphabet ,word memorizing, pronunciations and master of grammatical rules. Hard efforts should be made if you want to succeed it. In conclusion, it is significant for us to learn by heart rather than searching for a shortcut .As the saying goes, nothing in the world is difficult for one who sets his mind on it.

Introductions for study on advertising sales models of Oppo Oppo is a company manufacturing mobile phones with a seat in the phones market in China. At the beginning, either its popularity or the quantity of mobile phones couldn’t make it stick out from the nationwide market then. However, with Tony Chen’s leadership, Oppo has become one of the top three ranking brand companies in consumer phone sales over several years. What caused the company's good fortune? To figure out the reasons for the rapid development of mobile phones of Oppo, we specifically searched on the Internet for why they captured the Chinese market successfully. As the data shows, a fierce offensive in advertising is one of the significant reasons. In first-tier and second-tier cities, even the third and fourth-tier ones ,there are almost billboards of Oppo on streets everywhere. Apart from this, TV ads and web popups of hot sale ones can be seen here and there. From the advert ”five-minute charging for two-hour talk time” to “More clear at this moment” ,it is obvious that it found its way ever deeper into people’s hearts .In this passage, starting with the sales model of its advertisements, we can research how it succeeded in domestic mobile phone market sales as one of the top three.
