The dictionary isn’t forever. What happens to a word when its popularity starts to decline? Here’s how the process of deleting a word from the dictionary works.
The dictionary is actually a steadily enlarging volume. 1. New words arise from emerging and expanding disciplines. Definitions also change and shift, so common words gain new meanings. On the other hand, there are also words that become outdated. 2.
Who decides which words to delete? 3. While adding a word to the dictionary is a precise process, it’s even more difficult for a word to get deleted. Editors maintain and study vast language databases to keep up-to-date on the words in circulation across various media.
The Oxford English Dictionary covers the English language over the last 1,000 years, and it’s considered definitive and authoritative. 4. And each has its own process for additions and removals.
5. A 2019 petition(请愿)with 30,000 signatures calls for the Oxford English Dictionary to remove sexist language and definitions, especially those terms under the word “woman.” And Merriam-Webster recently changed definitions of identity-related words to reflect new cultural meanings around fairness.
A. Some new words might be out of date one day.
B. As a result, words get removed from the dictionary.
C. Dictionary additions and deletions reflect social changes.
D. It’s up to the dictionary editors to make the final decision.
E. That’s because the English language constantly develops and changes.
F. These are often the types of words that will make it into dictionaries.
G. However, there are many other dictionaries that are reliable and trustworthy.
Step into Moving to Mars, an exhibition of Mars mission and colony design at London’s Design Museum, and immediately you have good reasons not to move there.
Frightening glowing wall-texts announce that Mars wasn’t made for you； that there is no life and precious little water: that, dressed in a spacesuit, you will never touch, taste or smell the planet you now call “home”. As Lisa Grossman wrote for New Scientist a couple of years ago, “What’s different about Mars is that there is nothing to do there except try not to die”.
It is an odd beginning for such a celebratory exhibition, but it provides a valuable, dark background against which the rest of the show can sparkle (闪耀)—a show that is ,as its chief manager Justin remarks，“not about Mars ； this is an exhibition about people”.
Moving along, there is a quick yet clear flash through what the science-fiction writer Robinson calls “the history of Mars in the human mind”. A Babylonian clay tablet and a Greek vase speak to early ideas about the planet. A poster for the original Total Recall film reminds us of Mars’s psychological threat.
The main part of the show is our current plans for the Red Planet. There are real spacesuits and models of 3D-printed Martian settlements and suitable clothing and furniture. Mission architectures and engineering sketches line the walls. Real hammers meant for the International Space Station are wall-mounted beside a low-gravity table that has yet to leave, and may indeed never leave, Earth.
This, of course, is the great strength of approaching science through design: reality and assumption can be given equal visual weight, drawing us into an informed conversation about what it is that we actually want from a future on Mars.

A.An experience. B.An opinion. C.A fantasy. D.A solution.
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 (吸) 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

I was excited to take my rescue Beagle (比格犬) to the river the other day, as it’s within walking distance of our new home. Having spent her first six years in a cage, Georgie had never seen a body of water, and I wanted to get there before sunset to watch her experience it.
I was growing increasingly impatient about all the stops her little Beagle nose required. She inspected the grass, dirt, and trees, and licked (舔) whatever was stuck to the road. These were all new discoveries for her, and she took her time studying them.
When I accepted that it was fruitless to hurry her along, I whipped out my cell phone and began texting. I thought that I needed something to do while Georgie was slowing us down. Then, for some reason, I heard the cicadas (蝉) ,and I remembered that the sound of cicadas is my favorite sound in the world. That awakened something buried within me that longed for the simple pleasures that had been replaced by technology.
I made a conscious decision to be present, and to enjoy the journey to the river Just like Georgie. Now, I admired the flowers and the winding ivy on our path. I smelled the grass and the flowers, and the dirt and the air. I treasured each one equally, as if discovering them for the first time.
As we neared our destination,1 realized something even more important: It didn’t matter if we even reached the river. Why must there always be a destination? Georgie had no idea that we had a destination. She was present for the journey, and she savored every bit of that sweet experience. There was no race and no finish line.
