BDS appears later     2     America's GPS, Russia's GLONASS and EU's Galileo, but it can match them. As one of the fourth     3     (globe) navigation satellite systems, BDS involves efforts of over 400 agencies and 300,000 research personnel and technicians.

Originally     4     (plan) in the 1980s, the network represents a milestone in China's space effort. BDS is comparable to GPS in terms of the     5     (accurate) of positioning. It also offers short message communication and thus can provide emergency communications in areas       6     conventional communication signals are poor in an effort     7    (improve) the quality of their positioning services, Apple and Samsung phones, among others, are already using BDS's signals, and so    8     (be) every Chinese brand.

The construction of complete BDS is a huge technical achievement for China and can     9     (easy) pay     10    in the near future. Meanwhile, BDS's great contribution to promoting the world's economic and social development as well as the peaceful use of space has attracted the world's attention.

AirCar is the latest generation flying car     1    transforms from road vehicle into air vehicle in less than 3 minutes. Useful for leisure and self-driving     2    (journey), the vehicle can go from driving to flying mode with the click of a button. The fifth generation flying car designed by Professor Stefan Klein     3    (complete) two flight tests at Piestany airport in Slovakia so far.

The two-seat AirCar     4    (weigh) 1,100 kg and can carry an additional load of 200 kg per flight.     5    (power) by a BMW 1.6 L engine, the car-plane has an effective power output of 140 HP. The estimated travel range of the vehicle is 1,000 km       6     the flight consumption is 18 liters per hour. AirCar can transform from a ground-based vehicle to aircraft with its speed     7    (reach) up to 200 km/h. But most importantly, the stability and controllability of the AirCar is     8    (access) to any pilot.

“With AirCar you will arrive at your destination     9     the trouble of getting a ride to airport and passing through commercial security. You can drive your AirCar to the golf course, the office, the shopping centre or your hotel and park     10     in a normal parking space,” said Anton Zajac, Klein Vision’s co-founder, investor and pilot.

It's common       1     (see) food delivery workers on electric bikes through crowded cities in China. Most of them are in     2     hurry. However, such reckless(鲁莽的) behaviors often cause serious problems.

One deliveryman surnamed Li     3    (interview) the other day. He's been only doing this job for 2 weeks but has already ridden in wrong lanes a few times just to be punctual. In the     4     (one) half of last year, food deliverymen had 76 traffic accidents in Shanghai alone,     5     means on average, a food deliveryman got hurt or died every 2.5 days.

The phenomenon is       6    (close) related to the growing demand for delivery services, reported People's Daily. About 10% of Chinese are turning to food delivery services, according to China Radio International. Such a huge market     7    (lead) to booming delivery growth by now, with companies offering high salaries to attract new staff.

However, food de liverymen are often under high pressure, faced with fines of ¥20 for being late and up to ¥200 for receiving complaints. Also, the more orders, the higher earnings. Thus,     8    (safe) pops up as a big concern.

Solution? Yes. Shanghai has laid stress on traffic rules. Now in Shenzhen, if caught     9    (break) traffic rules twice, the deliveryman is banned     10     driving vehicles for a whole year!

If you always hate certain vegetables, you may be more than a picky eater. Instead, you might be a "super-taster", a person     1     bitter genes(苦味基因). Those people who have the "bitter genes" are 2.6 times more likely to eat     2     (few)vegetables than others, according to a new study     3     (present)at the annual meeting of the American Heart Association.

"We don't get the taste of food equally," said Professor Duffy an expert in the study of food taste. "it could explain some of the differences in our food     4    (prefer)."

About half of us can taste bitter and sweet, so we are not especially sensitive to bitter food. Another 25% are called "non-tasters", to     5     bitter food might actually be a bit sweeter. The rest of us are     6     (extreme)sensitive to the bitterness that some     7     (plant)develop to keep animals from eating them.

Food scientists are trying to develop ways     8     (reduce)the bitterness in vegetables, in     9     hope that we can keep super-tasters from rejecting vegetables. In fact, some vegetables we grow today     10    (be)much sweeter than before. We might also try to use various cooking methods, either by adding some fat, sweetness, strong flavors like garlic or roasting them, to improve the taste of the vegetables.
