4. 阅读理解 Are you always disturbed by the noise made by your coworkers while you're working hard at your task? What kind of feelings will you have on hearing such kind noise? Have you ever got an idea that a certain helmet will help you out of the trouble no you can focus on your work at the office? Now, you needn't worry for the “Helmfon” will help you ignore noisy co-workers and other distractions.
Created by Ukrainian design company Hochu Rayu, the Helmfon is a big helmet that uses special equipment to absorb the sound so as to completely block out any outside noise, giving the wearer their own quiet personal space so they can better focus their attention on their work. Made of a glass fiber shell, cloth and polyethylene（聚乙烯）, the helmet not only blocks outside sound, but it also keeps the noise you make in, allowing you to answer calls, hold Skype conferences, watch or edit videos, privately.
The company came up with the idea for the Helmfon after being asked to design a new phone booth for an IT company. The project
made the team think about the way we communicate and finally begin work on a device that would allow you to be in two worlds just sitting on your chair in the office, in a meeting, or everywhere you feel like just wearing your helmet.
The Helmfon comes complete with a system board, microphone, speakers, and a special holder for your phone. The only trouble is that it makes you look like a character from Mel Brooks famous movie Spaceballs, but the company also made public a variety of great choices, including Bat man-inspired design, and even a Native American headgear.
The Helmfon is still in prototype（维形）stage, but the Ukrainian company is already working on a commercially available design and plans to offer the design for sale. A release date has not yet been made public.
