Apple has entered the textbook market. The technology giant(巨头) introduced iBooks textbooks in early February, 2012.

    iBooks textbooks are digital books in different subjects, including science , maths, history and geography. The company offers a collection of textbooks to high school students. It offers a “new textbook experience” and suggests its iBooks textbooks are “the next chapter(章节) in learning”.

It sounds like good news for students. Think of it. No more carrying heavy school bags full of textbooks. Every textbook you need can be stored on your iPad. No more having to buy expensive textbooks which you will only use for a year or two and then sell or give away.

Of course there’s a hidden difficulty. You need to own an iPad and as you know, it is not cheap.You also need to buy digital- textbooks, most priced each at $ 14.99 ( 94.74 yuan) or less.

You can play videos, work out geometrical(几何的) problems in 3D，listen to music and make notes. You can share your learning materials on networking sites with other students. Instead of boring textbooks which are quickly out of date, you can have an interactive(互动的) learning experience.

Will Apple revolutionize(变革) learning? Let’s wait and see.

If you get a good English dictionary，you will be better than 90% of English learners．Most people（even people who want to learn English very much）simply go to a bookstore and buy the first dictionary they see．

That is a big mistake! A bad dictionary will give you problems sooner or later- maybe in two months，maybe in one year - and you will have to buy a good one anyway !Isn't it better to buy a good dictionary at the first time?

Getting a good English dictionary is important because a good dictionary will be your guide to English．It will teach you new words，how to pronounce them and how to use them．It will help you understand English texts．Successful English learners use their dictionaries all the time：when reading books，at English classes，when writing e-mail，when doing homework，when surfing the Web．

It is an easy first step in your English-learning program -you only need to spend a little money（much less than you would pay for an English course）．Once you've made the first step， it will be easier for you to do the rest．

You need to spend money on it．Yes，this is a good thing．Spending some of your money on learning English will give you an encouragement to learn English well．
