Every day we go to school and listen to the teacher,and the teacher will ask us some questions.Sometimes,the classmates will ask for your opinions of the work of the class.When you are telling others in the class what you have found out about these topics,remember that they must be able to hear what you are saying.You are not taking part in a family conversation or having a chat with friends—you are in a slightly unnatural situation where a large group of people will remain silent,waiting to hear what you have to say.You must speak so that they can hear you—loudly enough and clearly enough but without trying to shout or appearing to force yourself.

Remember,too,that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you.The person you are seeing will try to put you at your ease (not worried) but the situation is somewhat different from that of an ordinary conversation.You must take special care that you can be heard.

While inventions like the wheel and the Internet have changed the way the world works today, there are some creations that never quite got off the ground. Let’s look at the strangest inventions from across the globe.

THE TOMATO-FEEDING ROBOT

Japanese juice seller, Kagome, invented a robot that will feed you tomatoes with its long metal arms extended on either side of your face while you run. Originally created for the Tokyo Marathon, the robot even has a timer so that tomato-eating runners won’t use up their supply too quickly.

THE ROLLING BENCH

It’s lunchtime and many people may be looking for a park bench to sit on, but the rain has made every surface humid. This is when the rolling bench comes in. When one side is too wet, a handle on the side can roll up another dry side for better sitting conditions. The inventions come from designer Sung Woo Park, from Seoul in South Korea.

THE LED SLIPPERS(拖鞋)

We all hate hurting our toes in the dark, but a revolutionary footwear design can prevent this from happening again. The slightly strange LED slippers are designed to be comfortable, yet shine your path at night. With two in-built LED lights at the top of each slipper, the users can direct their toes at any area that needs light.

THE FOOT-POWERED BICYCLE

It’s the unusual invention of German designers Tom Hambrock and Juri Spetter. Besides an unusual appearance, its function is also slightly strange, as the user must run to get the bicycle moving. As soon as the riders have enough momentum(动力), they’re able to rest their feet on the back wheel and use the handlebars to control its direction.
