City Transformer,a four-year-old company based outside Tel Aviv,Israel,is ready to shake up the auto industry with their invention.
So what is it that they’ve created?A car that actually folds while you’re driving.It’s a neat trick,sure.Perhaps something you’d see in a superhero movie.But it actually serves a practical purpose.With more people choosing to live in urban environments,space can be tight.Picture yourself pulling up to a tiny parking space that’s only big enough for a motorcycle.No problem.Hit the button,and your car shrinks to fit into the space.
The car,which is available for pre-order now,is a case study in clean design.It contains only 1,000 parts,compared to the industry standard of about 20,000 in a regular car.It’s all electric,and doesn’t run on gas,causing no pollution.It’s autonomous-ready,which means that one day it will be able to drive itself.
City Transformer is considering a company of foldable cars positioned all across the globe.People who own membership of the car rental company can rent one of the cars wherever they are.What’s more,when you get into any of the cars,it will instantly recognize you and adjust the seats,temperature and music to your favorite settings.
Asaf Formoza,the company’s founder,believes it’s at the right place,at the right time.“It's very important for us to be in Israel,because we have more than 400 companies here just for the automotive departments,”he explained.“And we can take some of their proven technologies and adopt them to our car.”
“To bring something like that as a solution for cities when so many people around the world are stuck in traffic jams,this is going to be something that I think can really change the experience of drivers,”said project manager Itamar Meridor.

C. It takes up less space. D. It has a higher speed.
2.What can the car do when a person sits in it?

C. Take his or her temperature. D. Provide personalized services.
3.Why does Asaf Formoza say the car is at the right place?
A. Israel is a large market for cars.

C. The road conditions in Israel are nice for cars.
D. The new technologies are available in Israel.

Like toolmaking,teaching was once thought to be an exclusive（独有的）capacity of the human mind.It is not actually.
“Teaching”requires this:one individual must take time from their own task to demonstrate and instruct with effort and the student must learn a new skill.That’s a tall order.
When a young chimpanzee watches a skilled adult and then imitates（模仿）,that’s learning.But the adult has not taken time specifically to instruct,so it is not teaching.In the honeybees’ amazing dance,the dancer takes time to indicate information about a source of food,but observers learn no new skill.They do take time to show,but they do not pass on new skills to learners.
Dolphins teach.Atlantic spotted dolphin mothers sometimes free a caught fish in the presence of their youngsters and let their youngsters chase it,catching it again if it’s getting away.Dolphin youngsters also position themselves alongside mothers who are scanning sandy bottoms for hidden fish,and the mother spends extra time demonstrating.
Other teachers include:housecats who bring back live prey and let their young learn to catch it,and meerkats（猫鼬）who first bring to their growing young dead scorpions（蝎子）,then disabled ones,to demonstrate how to remove the poisonous part on their tails.
Like toolmaking and teaching,imitation is also considered to reflect high intelligence.In South Africa lived a baby dolphin named Dolly.One day while she was just six months old,Dolly was watching a trainer standing at the window smoking a cigarette,blowing puffs of smoke.Dolly swam to her mother,got a mouthful of milk,then returned to the window and released a cloud of milk that surrounded her head.The trainer was“absolutely astonished”.Somehow Dolly came up with the idea of using milk to represent smoke.Using one thing to represent something else isn’t just imitation.It is art.
1.What does the underlined phrase“a tall order”probably mean in paragraph 2?
A. A clear instruction. B. A high risk.
C. A difficult requirement. D. A useful purpose.
2.What do we know about honeybees’ dance?
A. Presenting. B. Learning.
C. Imitating. D. Teaching.
3.What can we infer about animals that can teach?
A. Bees show their dance to younger generations.
B. Housecats teach in a way similar to dolphins.
C. Young dolphins must learn how to free a fish.
D. Meerkats have poisonous parts on the tails.
4.Why does the author use Dolly’s example?
A. To prove smoking can affect other animals.
B. To explain dolphins are capable of making art.
C. To show animals can be surprisingly intelligent.
D. To stress milk is to dolphins what smoking is to men.
I go out of my way to say“thank you”to my partner frequently,and he’s the same way.We were both raised by parents who valued politeness,and more than that,I want to do all those little things that psychologists say help couples stay together.Expressing gratitude（感谢）is one of those things,so a quick“thanks”seems like an easy one.
But according to a recent study,we’re not at all typical.The study looked at over l,000 recordings of casual conversations among families and close friends.In only about one out of 20 times were expressions of thanks observed.Phrases that meant“thanks”but weren’t a direct translation of the word were counted,including physical gestures of thanks.
The researchers looked at a wide variety of people from different places,representing eight languages:Polish,Russian,Italy,English,Murrinh-patha (an Aboriginal language),Cha’palaa,Lao and Siwu.
The Brits thanked people close to them the most,about 14.5 percent of the time,and close behind them were the Italians at 13.5 percent.The Murrinh-patha came next at 4.5 percent and following them were the Russians,the Polish,the Laotians and the Siwu speakers.The lowest?Well,the Cha'palaa speakers of Ecuador don’t have a word for“thank you”at all.
As the linguists explained,“Expressing thanks,in some cultures,is more of a linguistic tradition than a true expression of feelings.In cultures where thanks are less often said,it’s because social cooperation is taken for granted,and‘thank you’ isn’t really needed or necessary.”
The idea that you don’t need to thank others because it’s assumed that you’re appreciative is beautiful.But it is a bit hard for me to accept.So I’ll keep saying“thanks”as frequently as I do.But as a frequent traveler,I’ll keep in mind to watch the local custom and follow suit.
1.What might be psychologists’ opinion about expressing thank?
A. It can show a person’s values.
B. It is passed down from parents.
C. It is a little and unnecessary thing.
D. It can contribute to close relationship.
2.What is typical among family members according to the study?
A. They say thanks at any time.
B. They seldom express thanks.
C. They often show thanks using gestures.
D. They often use indirect translation of thanks.
3.Who never say“thank you”?
A. The Cha’palaa. B. The Polish.
C. The Italians. D. The Russians.
4.What is mainly talked about in the text?
A. People thank close friends and family less.
B. Family members don’t need to thank each other.
C. Close friends have different ways to express thanks.
D. Different cultures have different ways to express thanks.
