M: What did you get for your birthday this year,Catherine?
W: My grandpa gave me a watch,and my sister got me a bicycle.But the coolest gift was from my daddy:a new car!
M: Wow,you're so lucky!
M: When does the movie start?My watch says 8:10 pm.
W: Well,the lights will go down at 8:15,but we'll have 5 minutes of ads before the movie begins.
W: Did you have a good time in the countryside?
M: Well,I was happy working on the farm,but I had to drive a long way to buy the things I needed.
M: This is not what I ordered from Taobao.
W: What?They sent you the wrong coat?
M: No,it's the same brand and size but twice as dark as I was expecting.
W: Excuse me,sir,but I need to leave early today.
M: What is your problem?
W: I'm not feeling well.I have to go home and take some medicine.I'll be back in time for class tomorrow.
M: Hello, Lucy. What about your test?
W: Not too bad.But the trouble was that I kept thinking of so many things at once,so I didn't have time to finish the test.
M: How many questions did you answer?
W: Oh,I did nine of them.But I didn't really have time to finish the last one properly.
M: Oh well,don't worry.I'm sure you'll be all right.
W: Hmm,I hope so.But if only I'd done the last question properly.
M: Oh,come on.One question isn't everything.And I'm sure you did enough of it to pass.
W: Well,anyway,at least it's over.
W: Hey,we should watch the kids more carefully when they're in the pool.Did you ever hear about secondary drowning?
M: No,never heard of it.Is that like when you get water up your nose?
W: Don't joke about it!I learned it from the Internet.Some children die each year because they fell into a pool,or a lake,but they didn't drown right away.Someone pulled them out of the water and they seemed okay for the first day.But a lot of water got into their lungs,and the next day,they died.
M: It happens very rarely.We have to let the kids have fun.We can't protect them too much.
M: Hey,Helen!Want to play a new game I learned in school today?
W: Yeah!How do you play it?
M: You stand over there by the side of the house.I'm going to throw this ball at you.
W: Wait a minute!That's a big ball!You're going to hurt me!
M: Don't worry.It's a light ball.And I won't throw it too hard.Anyway,when I throw it at you,you have to try to get away from it.Don't let it hit you.You have to move fast.Sometimes,you might have to lower your head to get out of the way.
W: You're going to throw it at my head?
M: Like I said, I'll throw it gently.The point is,you always have to try to avoid the ball by moving away from it.
W: Mike,can I be honest with you?
M: Sure,Cindy.What's up?
W: This food is tasty.But I'm not sure it's very healthy.
M: Well,this was my first time to cook for you.I guess I was a little nervous.
W: That's sweet.
M: I put too much salt on the potatoes.
W: Yeah,I like salty food.
M: And I overcooked the steak.So I tried to cover it up by adding more butter.
W: Well,it's not easy to cook a steak.My dad has been trying to teach me that forever,and I still never know how it's going to turn out.
M: I know you've cooked a lot before.I suppose I just wanted to impress you by telling you that I loved to cook,too.I don't know what I was thinking!
W: It's the thought that matters.Maybe we could make something together next time.
M: That would be awesome.Uh,Cindy?
M: I'm pretty hungry,but I don't think I can eat another bite of this food.How about going out to eat somewhere?
W: I know a great Mexican place around the corner.
M: Let's go.
M:You know how much your car has changed over the past 10 years?Your car will change even more than that in the next 10 years.One of the big changes is that cars will drive themselves.Some day you may not need to drive a car.You will just tell the car where you want to go and it will drive itself.
An American company has been working on a self-driving automobile for years.These cars are already on the roads in the United States,mainly in California.They are truly self-driving and have no steering wheels or pedals.Last week,the police ordered one of the cars to stop because it ran too slowly on a public road.The car was not breaking any law,so no one was punished.But the police did speak with the operators of the vehicle.According to the company,its self-driving cars have driven nearly 2 million kilometers.That is equal to the distance an average person drives in 90 years.So far, no self-driving car of the company has gotten a traffic ticket.Some of them have been in accidents:other cars hit them.
