【题目】 Umbrellas are certainly one of life’s necessary helpers. But as anyone ever caught in a heavy rain will tell you, they’re far from perfect. So, many creative designers made efforts to challenge. Here are three unusual umbrellas that can solve the rainy day problems:

Senz

Problem: Common umbrellas love to invert(翻转) when it’s windy.

The Senz umbrella changes the found shape into the one that is long in the back and short in the front. The design is much stronger against even strong against even strong winds, and according to their tests, it won 't invert in a windy storm

Kazbrella

Problem: Once closed, umbrellas drip(滴水)all over everything and they need a lot of room to open up.

The Kazbrella tries to solve this problem. It opens in a special way. When closed, it looks like the common umbrella upside down, but when it opens, it is similar to the common one. The design allows the wet side of the umbrella to be inside once you fold it. As a result, getting in and out of your car is not a problem. You can close Kazbrella into the smallest space of a car door, remaining dry.

Rain shield

Problem: Rain can hit you from all directions.

In the face of a heavy rainstorm, a little more surface area would be a big help. So the Rain Shield has been given an extension(延伸)to one side, giving the protection from the side way rain and lowering the risk of being invert. And its bendy (弯曲)design means it is easy to take.

Don't you think that these umbrellas are fascinating? The good news is that you can buy Sen and Kazbrellas in London now.
