Gmail turned five years old this week．It’s somewhat amazing to think we’ve only had it since 2004; Gmail changed the webmail game forever by offering features we now take for granted：a streamlined interface(界面), powerful search, pioneering use of Ajax and a then－huge 1 GB of mailbox space．“You’ll never need to delete another message”was how Google described it at the time．
Back then, I was still making do with Hotmail．But its clumsy interface and tiny amount of storage space made the decision to move on an easy one．Getting an account made all the difference in the world to my email experience．Suddenly I was freed from having to delete emails every few days to make space in my mailbox．And the app(application)was smooth and responsive, like a desktop client(客户端程序)－and pretty fast in comparison to Hotmail．“Conversation view”and using labels instead of folders took a little getting used to, but in all Gmail felt far more professional and made me much more productive．
Gmail is a favorite app of ours ever on Web Worker Daily, and with good reason．It’s still the best webmail client for web workers as it lets us access our email whenever and wherever we need to, on any device, with minimum effort．And Google hasn’t spent the five years sitting on its Gmail success, either, but has introduced improvements to the service that include Gmail Tasks, chat, video chat and voice chat, combined with Google Calendar and Docs, Google Apps for Domains, and, of course, even more storage．We’ve recently covered the many features found in Gmail Labs: a way to“undo”sent messages, using canned responses for smart auto-responders, offline support using Gears and how to customize the way you view your mailbox using multiple inboxes．
(1)
The underlined sentence in the first paragraph implies that ________．
[ ]
A．
we shouldn’t take Gmail for granted
B．
you can try to write any kind of message
C．
Gmail can correct your mistakes of itself
D．
you needn’t worry about the mailbox space
(2)
Which of the following is not Gmail’s striking feature?
Suppose we built a robot(机器人)to explore the planet Mars．We provide the robot with seeing detectors(探测器)to keep it away from danger．It is powered entirely by the sun．Should we program the robot to be equally active at all times?No．The robot would be using up energy at a time when it was not receiving any．So we would probably program it to stop its activity at night and to wake up at dawn the next morning．
According to the evolutionary(进化的)theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason．The theory does not deny(否认)that sleep provides some important restorative functions(恢复功能)．It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous．However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us．So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent．
The evolutionary theory explains the differences in sleep among creatures．Why do eats, for instance, sleep so much, while horses sleep so little?Surely cats do not need five times as much repair and restoration as horses do．But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep．Horses must spend almost all their waking hours eating, because what they eat is very low in energy value．Moreover, they cannot afford to sleep too long or too deeply, because their survival(生存)depends on their ability to run away from attackers．

Our boat floated on, between walls of forest too thick to allow us a view of the land we were passing through, though we knew from the map that our river must from time to time be passing through chains of hills which crossed the jungle plains．Nowhere did we find a place where we could have landed：where the jungle did not actually spread right down into the river, banks of soft mud prevented us going ashore．In any case, what would we have sailed by landing?The country was full of snakes and other dangerous creatures, and the jungle was so thick that one would be able to advance only slowly, cutting one’s way with knives the whole way．So we stayed in the boat, hoping we reached the sea, a friendly fisherman would pick us up and take us to civilization．
We lived on fish, caught with home-made net of string(we had no hooks), and fruits and nuts we could pick up out of the water．As we had no fire, we had to eat everything, including the fish, raw I had never tasted raw fish before, and I must say I did not much enjoy the experience; perhaps sea fish which do not live in the mud are less tasteless．After eating my raw fish, I lay back and dreamed of such things as fried chicken and rice, and ice-cream．In the never-ending damp heat of the jungle, ice-cream was a particularly frequent dream．
As for water, there was a choice：we could drink the muddy river water, or die of thirst．We drank the water．Men who had just escaped what had appeared to be certain death lose all worries about such small things as diseases caused by dirty water．In fact, none of us suffered from any illness as a result．
One day we passed another village, but fortunately nobody saw us．We did not wish to risk being taken prisoners a second time：we might not be so lucky to escape in a stolen boat again．
