All too often,their demands have been met. Why?________(50)that would result if the public found out that their computer had been misused.They hesitate at the thought of a criminal

[填空题]Simon:
As a budget traveller I like to hit the road with a backpack whenever I can. I’ve found www. Hostelbookers. Com a great resource for booking hostels in advance of arriving at a destination. No booking fees means competitive prices, and all hostels are rated by others on the gringo trail, so you get a good idea of what to expect on arrival.
Perth:
When I want to read some good travel writing, mixed in with some pithy comment, interviews and news, I check out www. Thetransitcafe.com. The writing is very fresh.
Kim:
What many people look for online, but rarely find, is an online guide that tells it like it is without the travel agents’ waffle. For anyone heading to the island of Koh Chang, Thailand, www.Iamkohchang.com is a must. Run by an English guy who’s been living there for a few years, it’s a fun and highly informative look at what the Thai tourist authority really does call "The Oriental Eden of the East."<
