题目原文:
An airship is a type of aircraft that flies using a very large balloon filled with a lighter-than-air gas. Airships were an important means of air transportation before the 1940s but are little used today, having been largely replaced by airplanes and helicopters.However,some aeronautical engineers believe that airships could become popular again because they offer a number of advantages over airplanes and helicopters.
One advantage of airships is that for vertical lift(the force that keeps the ship airborne),they use a balloon that floats rather than an engine.Airplanes and helicopters use engines for both vertical lift and horizontal movement,but airships use engines solely for horizontal movement.So,airships use less fuel than a typical aircraft-thus making their fuel costs more economical.
Another advantage of airships is that they can be used in hard-to-reach locations.Unlike airplanes, airships do not require a long runway for takeoff and landing because of their ability to lift off and land vertically.The only other aircraft capable of ascending into the sky by going straight up and descending straight down to the ground is the helicopter,which can carry only a small amount of weight.Airships,meanwhile,are able to carry very heavy loads.As a result,airships could do jobs that neither airplanes nor helicopters can do,such as carrying heavy logs from forests to distribution centers.
Finally,airships could even be used to replace satellites.Currently, satellites are launched into Earth’s orbit carying all kinds of equipment important in telecommunications or in surveying large areas of Earth’s surface for military purposes.Since airships can also rise high above the surface and stay there without refueling for a significant amount of time,they could provide services similar to those provided by satellites,and at a considerably cheaper cost.

公司员工晋升标准
Criteria for promotion may include employees’ performance and achievements in their current roles, seniority within the company, years of experience in the field, or even leadership potential. In today’s post, I would like you to discuss which criteria for promotion you see as the most important and explain why.
Student A: Andrew
I believe that when considering promotions, managers should reward employees’ seniority, or how many years they have stayed with the company.
Student B: Claire
In my opinion, it is more important to look at employees’ job performance. If employees are excelling in their current roles, this better indicates their readiness for the next step in their careers.
