【题目】 Mosquitos can infect you with Malaria, yellow fever, and dengue. All can kill you. So we spray large areas with pesticides (杀虫剂) .But this negatively affects the whole ecosystem and your health. Now there’s a new device, which claims to keep you and your loved one’s mosquito free.

The device was designed by two German engineers who were fed up with being bitten while camping. They found solutions containing ‘DEET’ — a damaging chemical which could be both harmful to us and the environment — worked best, but still only for 45 minutes maximum and that the traditional anti-pest devices didn’t work well! So, they designed the brand new type of bug killer, Moskinator.

Instead of trying to keep the mosquitos away, it actually attracts them, then catches and kills them! It lures (引诱) the flies and mosquitos near using a safe, completely harmless LED light. The flying pests (害虫) can’t resist the UV-PT light! Next to the LED light is a powerful, yet efficient reverse fan that sucks () the insects through a one-way trapdoor. Once trapped in the drying basket they are dried to death by the fan a matter of 2 minutes. You can simply empty the dead bugs into the trash, without even touching them.

Does Moskinator really work in real life? We had some of our customers try it out in their homes. The results speak for themselves:

“My wife would complain she had a headache in the mornings whenever we used chemical pesticides. Now we use our Moskinator, and we wake up bite and headache free!”— Shane Maguire

“This Moskinator really works and you don’t have to worry about breathing any harmful chemicals.”— Jake Shearer

【题目】Changing Bit by Bit

A new contest challenges people to use micro:bit computers to solve problems.

Could you use your computing skills to aid the fight against illegal animal hunting? How about tackling ocean pollution or monitoring animals under threat of extinction?

A new global challenge called Do Your Bit aims to get young people using their computing creativity to solve real-world problems. It’s being run by a partnership involving the BBC’s micro:bit computer, the technology company ARM and a campaign called World’s Largest Lesson, and it's aimed at people aged 10 to 16. It kicks off on 16 September.

The contest in 2019 is based on two Global Goals: to protect life on land and under the water. To take part, young people first choose a problem that affects them and their community, then design something involving the micro:bit computer that could help to tackle that problem.

Participants need to write up to 500 words about the problem and their solution, as well as providing a photo of their drawn plans or a hex file of their prototype code (编码), plus any other photos and videos showing what they’ve done.

This is the second micro:bit Global Challenge to be held. In 2018, the contest's winning designs included a homemade thief alarm, a classroom health monitor, a food-waste watcher and a device to remind people to sit up straight.

The deadline for entering the challenge is 28 February 2020: the winners will be announced the following month.
