Some cool inventions are listed in Science Magazine's 25best inventions of 2018． They are "making the world better， smarter and in some cases a little more fun"， according to the magazine's website． Do you want to lean more about some of the inventions？ Let's find out．
● Spark
Spark is a new type of drones （飞行器） made by a Chinese company （公司） in Shenzhen called DJI． It can help people take photos and videos． Spark might be the smallest drone ever made． When folded， it is as small as a can of cola （可乐罐）． The coolest part is that users can control the small drone just by using hand gestures（手势）． For example， if you wave （挥动） your hand from left to right， the drone will fly in the same direction． When you want it to land， you just put your hand out． The drone will come to you and land on your hand．
● Social Robot
Robots may not be good communicators． But Jibo， made by US company Jibo Inc， may be different． With a big， round head and round， fat body， Jibo looks like a cartoon character． As soon as you say， "Hey， Jibo．" It will giggle（咯咯地笑）， dance and turn to face you． When it talks to you， it moves its head and body naturally to communicate with you． Although it has no eyes or mouth， Jibo uses animated icons （生动的表情）， such as a smile icon， to show emotions． Right now Jibo can only do some basic things， like taking photos or reading the news to you． But it may learn to do more in the future．

Marianne Carus，who started Cricket（蟋蟀）magazine in 1973 and served as Editor﹣in﹣Chief（总主编）until 2012，died on March 3 at the age of 92 this year.
Marianne believed that "only the best of the best is good enough for the young. "In Cricket，children would find wonderful stories with beautiful art，and be encouraged by ideas in the humanities and sciences.Marianne looked for stories from around the world to awaken admiration for different peoples and cultures.Most important，Cricket would never talk down to children.
Marianne knew that children were filled with fun，and she wanted Cricket to be，too - "humor from the heart that makes you laugh out loud. "And so she named her literary magazines after a funny group of bugs（虫子），such as Lady bung and Spider.
Over the years，Cricket has been read by millions of children and given many writers and artists their start.Marianne kept a special box of "love letters" to the magazine.She treasured these letters from Cricket readers，including long﹣ago readers.They told her that their interest in reading had begun with Cricket.
▲She considered other names，such as Troubadour or Taliesin，the singers and storytellers of old who traveled from one place to another to share their songs and stories.Then，one night，she was reading Isaac Bashevi Singer's memoir（回忆录）A Day of Pleasure，about his childhood in Warsaw.In it he wrote：There was a stove in Shosha's apartment behind which there lived a cricket.It chirped the nights through all winter long I imagined the cricket was telling a story that would never end. "That's exactly what Marianne wanted her children's magazine to do-to tell stories that would never end!So the name Cricket became her best choice.
Thank you for everything，Marianne.May the stories，and the laughter，never end!

It seems that food deliverymen （送货员） are always rushing in haste.We can always see them running every minute，and they seem to have lots of things to do the next minute.They wear blue，red or yellow helmets （头盔） and many of them don't follow traffic rules.They drive on the wrong side of the road and run red lights.They use mobile phones when they are driving.
However，not everything goes well with food deliverymen.In the first half of 2017，food deliverymen had 76 traffic accidents in Shanghai.That means every two and a half days，a food deliveryman will die or get hurt on the road.
What makes deliverymen take such risks？The strict rules of the food delivery companies and the worried customers may be the answer.Many companies will fine （罚款） a deliveryman up to 2，000 yuan if he can't deliver the food on time，reported China Daily.Fines also go to those who get bad reviews from customers.
To solve the problem，food delivery service companies need to do some changes.Some cities are also taking action.Shanghai has asked companies to train their deliverymen on traffic rules and safety.Now in Shenzhen，if a deliveryman breaks traffic rules more than twice，then he can't do the job for a whole year.

If you feel sad or upset，remember not to watch a happy movie.A sad movie may be more suitable for you.
Some scientists at Ohio State University，the U.S.，have found that sad movies can make people happier.They published their study in a magazine called Communication Research.
Scientists asked 361 college students to watch a sad movie called Atonement.The movie tells a story of two lovers who were separated.They died during World War II at the end of the movie.The 361 college students answered questions from the scientists before，after and three times during the movie to find out their different feelings，including sadness.
According to the result of the survey，scientists found out that people felt better after watching the sad movie.Scientists believed this was because the movie made them think about their own lives and relationships.Compared to those of the unlucky lovers in the movie，their lives were full of hope.
"I want to live my life to the fullest，and this movie has made me think a lot，" one student wrote.
Silvia Knobloch﹣Westerwick，the leader of the study，explained that bad moods （情绪） would make people more thoughtful. "Good moods are generally a sign that everything is fine.You don't have to worry，and you don't have to think about problems in your life，" she said. "But bad emotions，like sadness，make you feel terrible about your situation.Therefore，seeing a sad movie may make you feel bad，but that will cause you to think more about your own close relationships and value them more."

A.to help them make more friends

With so much free time on our hands during lockdown， many of us have entertained the idea of knowing more about the world． Learning a foreign language is a good choice． Here are a few examples， in order of time it takes people to learn them．
Latin languages （about 600 hours）
The popular Latin languages ﹣ Italian， French， Spanish and Portuguese ﹣ require about 600 hours to learn． Of these， Spanish and Italian are the easiest for English speakers to learn． They are followed by Portuguese and finally French．
Latin languages share many words with English．However，those shared words look or sound similar， but have different meanings over time．
Greek （1，100 hours）
Modern Greek is maybe the easiest language to learn that uses a different alphabet（字母表）．It is also a language that has contributed many words to English． Indeed， the president of Greece once gave two speeches at an international meeting that included just Greek loan words（外来词） as well as the unavoidable basic English．
Japanese （2， 200 hours）
Counting objects in Japanese depends on whether they are long and thin （like "roads"）， small and round （like "apples"）， thin and flat （like "sheets of paper"）， and hundreds more examples．
What Japanese you speak also depends on your gender（性别）． There's a "rough" language for men and a more "ladylike" language for women， but you must understand both．
Chinese （2， 200 hours）
Each Chinese written word is hardly understandable when spoken between a Mandarin （普通话） speaker in Beijing and a Cantonese speaker in Guangdong． If you think that's strange， consider our number system： the symbol "2" is widely understood but it's pronounced "two" in English and "duex" in French．
（1）For an English speaker， which of the following is the easiest to learn？
A． Japanese．
B． French．

（3）The purpose of this passage is to tell English speakers ．
A． how to learn some foreign languages
B． why they must learn a foreign language
C． some information on the difficulty of foreign languages
D． not to choose an Asian language to learn as it is too hard

Life does not last forever，so always live in the now．Don't neglect （忽视）the loved ones who care for you．Express your gratitude （感激）to your loved ones in words．Show your love with actions．Treat every day as the last day of life．In this way，when you are gone，your loved ones would have nothing to feel sorry about．
