Computer mouse
The basic computer mouse is an amazingly clever invention with a relatively simple design that allows us to point at things on the computer and it is very productive. Think of all the things you can do with a mouse like selecting text for copying and pasting, drawing, and even scrolling on the page with the newer mice with the wheel. Most of us use the computer mouse daily without stopping to think how it works until it gets dirty and we have to learn how to clean it. We learn to point at thing before we learn to speak, so the mouse is a very natural pointing device. Other computer pointing devices include light pens, graphics tablets and touch screen, but the mouse still our workhorse.
The computer mouse was invented in 1964 by Douglas Englehart of Stanford University. As computer screens became popular and arrow keys were used to more around a body of text, it became clear that a pointing device that allowed easier m

C. not mentioned
[不定项选择题]There is a certain inevitability that ebook sales have now overtaken paperback sales on Amazon’s US site.Amazon’s
Kindle 2 is so light and so cheap that it’s easy to see why people have rushed to buy it.Though I’m still not keen on the design of the Kindle,it is a vast improvement on its predecessor and certainly tolerable.Beyond the device itself,Amazon has done a great job of rolling out Kindle apps,ensuring that people like me-who have an iPad but not a Kindle can still join in the fun.
Once you’re into the Kindle ecosystem,Amazon locks you in tightly-just as Apple does with its iTunes/iPod ecosystem.It’s so easy to buy from Amazon’s store and the books are so cheap that it’s not worth the effort of going elsewhere.
While I remain opposed to Amazon’s DRM(数字版权管理)-indeed,I’m opposed to DRM on any ebooks-I have to admit
that the implementation is so smooth that most Kindle users won’t care at all that their ebooks can’t be moved to other
devices.
The ebook trend is nowhere near peaking.Over the next five years we can expect to see more and more readers move away from printed books and pick up ebooks instead.But I don’t think that will mean the death of the printed book.
There are some who prefer printed books.They like having shelves filled with books they’ve read and books they plan to
read;they like the feel of the book in their hands and the different weights and typefaces and layouts of different titles.In other words,they like the physical form of the book almost as much as the words it contains.
I can sympathize with those people.As I wrote earlier this week,my ideal situation would be for publishers to bundle
e-books with printed ones-in much the same way that film studio DVDs with digital copies of films.There’s no reason to think
that lovers of printed books will change their minds.There will undoubtedly be fewer of them as time goes by because more
people will grow up with ebooks and spend little time with printed ones.However,just as there are people who love vinyl
records(黑胶唱片),even if they were born well into the CD era,there will still be a dedicated minority who love physical books.
Since there are fewer of these people,that will mean fewer bookshops and higher prices for printed books but I don’t think the picture is entirely bleak.There is scope for smaller print runs of lavishly designed printed books and bookshops aimed at
book lovers,rather than the Stieg Larsson-reading masses.With mainstream readers out of the printed book market,
booklovers might even find they get a better experience.
According to the passage,the reason why the author opposes to Amazon’s DRM is that______.《》()
A.ebooks can only be purchased on Amazon.com
B.Kindle books are not compatible with other electronic reading devices
C.once implemented,ebooks can’t be transferred to other equipments
D.ebooks installed on Kindle 2 can’t be edited freely
