So there's one bullet zipping along and then falling, and then the other one just falls.

罗伯特：所以有一颗子弹快速移动然后落下，然后另一颗就落了下来。

Costs have doubled from their initial estimate; bits of the route have been lopped off; and the trains will not zip along as quickly as originally planned.

成本比最初估计翻了一番；部分路线已被砍掉；而且火车不会像原计划那样快速行驶。

Much to my dismay, however, I discovered that the seat post was seized-- meaning I could barely reach the pedals, not the biggest issue when I was zipping along.

然而，令我沮丧的是，我发现座杆被卡住了——这意味着我几乎够不到踏板， 这不是我快速前进时的最大问题。

My mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles.Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.

现如今，我的脑袋就盼着以网络提供信息的方式来获取信息：飞快的微粒运动。曾经我是文字海洋中的潜水者，现在我则像是摩托艇骑手在海面上风驰电掣。
