Passage Five
Before the arrival of the internet, computer files were exchanged via storage media such as floppy disks (软盘) which were sent by post or delivered by foot, bike, car or train. After the appearance of the internet, a term was invented for such exchange of information: the sneakernet. Now that the internet is established, and our connections have become faster, the sneakernet sounds outmoded. Nevertheless, the opposite is true when larger files are considered. Because storage media evolve much faster than internet connections, it becomes ever more interesting to choose the route of physical transport over the internet.
One of the routes is via carrier pigeon(信鸽). This may sound ridiculous (and it has been a popular joke for many years), but thanks to shrinking storage media, the speed and capacity of the pigeon internet promises to become quite amazing.
A well trained contemporary carrier pigeon can maintain a speed of 50
A. storing larger computer files
B. the fast speed of the internet
C. sending digital data on the internet
D. traditional ways of sharing digital files

Passage Five
Never before has flying been so controversial. In the space of two years, the environmental damage done by planes has gone from being something quietly discussed by scientists and committed environmentalists, to a headline-grabbing issue no one can ignore.
Even those who fly once or twice a year on holiday can’t help but feel a growing sense of guilt, while those opting for trips by car, train or ferry have a self-righteous spring in their steps.
Now, however, the backlash is beginning. The tourism and aviation industries are mobilising, and pointing out some awkward facts. Did you know that some ferries emit far more carbon dioxide than some planes That driving can release twice as much carbon as flying A new report from Balpa, the pilot’s union, even claims that planes can be better than train.

A. be heatedly debated in the scientific community
