In one way, it is the “greatest” drone ever. ...

In one way, it is the “greatest” drone ever. In another, though, it is the opposite of what a drone should be. Drone should be very lazy. They don’t have to work. Only their sister should be busy pollinating (传授花粉) and producing honey. However, for this drone, pollination is the very reason fur its existence (存在).

The drone, in fact is an invention of Ejiro Miyako. Miyako is a scientist from Japan. Many people, including Miyako have been worried about the future of food industry. Pollinating insects, especially bees, are falling in number. As a result, some plants can’t get pollinated and there will be fewer plants for us to eat. Scientists have been working hard to increase the number of bees. Unfortunately, they have had little success. Perhaps, Miyako thinks, it is time to build some robot bees instead.

Miyako’s bee, in fact, does not look much like a bee. It is based on a quad-copter. Miyako has put some brush hair on it. The hair is covered in special glue. They are able to pick up and hold grains of pollen(花粉) until they brush up against something else.

At the moment, Miyako’s robot bee still needs help from human operators. That’s because it can’t see where its target (目标) are. In the next step, Miyako will install visual recognition (视觉识别) software on his bee. After that, the robot bee will be able to see by itself.

1.In the first paragraph, the underlined “drone” refers to a kind of ________.

A. flower B. bee C. honey D. software

2.Ejiro Miyako is worried that ________ in the future.

A. we may be short of food

B. natural bees may not produce honey

C. his robot bee can’t see

D. natural drones can’t pollinate plants

3.Ejiro Miyako’s invention is used to ________.

A. produce honey B. watch natural bees work

C. pollinate plants D. increase the number of natural bees

4.Which of the following is a must for Ejiro Miyako’s invention?

A. Pollen. B. Drones and their sisters.

C. Brush hair. D. Visual recognition software.

5.According to the article, what will Ejiro Miyako do in the next step?

It is the second-brightest object in our night sky after the moon. It is one of man's the greatest scientific achievements. It's the International Space Station (ISS) that moves around Earth.

Nov 20 is the stations’ 20th birthday. In 1998, the first piece of the ISS was sent into space. Since then, 230 people from 18 countries have visited it. Five space agencies –those of the United States, Russia, Canada, Europe and Japan- worked together to build it. Weighing about 450 tons, it contains many different parts.

Generally, the ISS holds three to six people at one time. Astronauts living there work on a variety of different science projects. The ISS has hosted over 1, 500 such projects, according to NASA(美国航空航天局) But the station's hardware is aging. In 2011, Russia announced that the ISS will be retired (退役) in 2020 in order to prevent it from becoming dangerous "space junk". However, the US later said it would use repairs to make its service life longer to 2025.

The ISS costs 21-28 billion yuan to operate each year. Many believed that this money could be better spent improving conditions on Earth. In February, US President Donald Trump announced plans to end support for the ISS by 2025. The US will use its money for other projects, like next-generation rockets and deep-space missions.

Although China is not part of the ISS program, it has helped with some of the station's experiments. China will soon have its own space station, becoming the third country after Russia and the US to do so. The station is set to be finished around 2020.

1.How many people have already visited the ISS since 1998?

A.18 B.230 C.450. D.1500

A.5 years B.20 years C.22 years D.27 years

3.What do we know about the ISS from this article?

A.The US built the ISS all by itself.

B.The ISS can be used for 20 years

C.China is part of the ISS program and has its space station

D.21-28 billion yuan is spent operating the ISS every year.

It is the second-brightest object in our night sky after the moon. It is one of man’s greatest scientific achievements. It is the International Space Station (ISS) (国际空间站) that travels around the earth.

November 20th, 2018 marks the 20th birthday of ISS. In 1998, the first piece of the station was sent into space. Since then, 230 people from 18 countries have visited it. Five space agencies (航天局)—those of the United States, Russia, Canada, Europe and Japan—worked together to build it. Weighing about 450 tons, it has many different parts in it, including labs and solar panels. Generally, the ISS holds three to six people at one time.

The ISS costs $3-4 billion (21-28 billion yuan) each year. Many have argued that this money could be better spent improving conditions on the Earth.

Under the pressure of the public, last February, US President Donald Trump announced plans to end support for the ISS by 2025. The US will use its money for other projects, like next-generation rockets and deep-space missions, the Washington Post reported.
