Iron Man suit

钢铁侠战衣

Have you ever imagined what fun it would be to fly to school? This Iron Man-style suit from a British company could make your dreams come true.

The suit allows users to fly just like Iron Man. Wearers can take off straight and fly through the air. It is powered by five mini jet engines— four are built into units close to the hands and one is built into a backpack. It can reach a top speed of 80 km per hour. There is a long way to go before this technology is available to everyone, as the suit is still quite expensive - one model recently sold for $ 440, 000 (about 3 million yuan). It is also very noisy. The inventors hope to improve it in the future.

3D-printed houses 3D

住宅打印

Food, water and home are basic human needs. But there are 1.2 billion people in the　 world who don’t have a proper house to live in. The 3D printed houses made by ICON in Texas may help to solve this problem. The company can print a single- storey 60-square- meter house in just 12 to 24 hours. The walls of the house are made of a special cement(水泥) that looks like cream. Later, workers can make the walls stronger. The 3D-printed houses use less cement than normal houses, If all goes according to plan, 100 homes will be built for people in The Republic of Panama in Central America this year. Each house costs $ 10, 000 (about 69,000 yuan).

At present, almost everyone has a mobile phone, but have you ever thought that cell phones 　　　　　 be bad for your health? A study shows that heavy mobile phone use may cause hearing loss.
This study shows that people who use cell phones for about an hour a day have a 　　　　　　 time hearing some similar sounds, especially in their right ears. It is getting harder for 　　　　　 to tell the difference between the sounds of “s” and “f”, and “t” and “z”.
Researchers studied 100 people who used cell phones and 　　　　　　　 them with 50 people who did not. The study lasted for 12 months. What the researchers found was that cell phone users had more hearing 　　　　　　 than those who did not use cell phones.
Besides this, our ears have many little 　　　　　　 inside them. Too much noise will cause these hairs to get weak and 　　　　　　　 die. When these hairs die, it affects our ability to listen.
However, cell phone users don’t care too much 　　　　　　 this study. One man said, “I’d be more worried about people who 　　　　　　　 MP3 players. They put those earphones in their ears and listen to very 　　　　　　　 music. I think that is more likely to cause hearing loss than a cell phone.”
