Car trip一般都是比较愉快的阅历，所以这个雅思口语话题你能够开心的跟考官分享，不过假如大家想给自己加点儿戏，聊一聊中间不那么愉快的小插曲，当然也是OK 的啊，例如被警察pull over (of the police, to make a driver or vehicle move to the side of the road)，或者途中的小accident等等。
This topic reminds me of the time I went on a road trip to Tibet.
On our way there, we passed a huge piece of grassland where the scenery was breathtakingly gorgeous. We pulled over, and stepped outside to do some sightseeing.
There was this lake called Moon Lake, ‘cause it’s in the shape of a curved moon. The water is crystal clear. I could even see the bottom of it. And I saw a scattering of sheep on the grass, which was so cute, you know, the little white spots stood out against the green grass.
But we had a pretty tight schedule, so we couldn't spend too much time admiring the views, which is quite a bummer.
Oh, I almost forgot, there’s another experience that was not that pleasant. Here’s what happened. On the grassland, some local people offered tourists to have a ride on their horses, and they would charge you some money for that. I didn’t know that they tend to overcharge tourists, so I just got ripped off. When we went back to the parking lot, the guy working there told us, if we want to ride horses, we could pay 30 RMB to do that, but the fact is, we got charged double the price. I was like, ‘What the hell?!’
So, it’s fair to say, this car trip is a bittersweet experience.

上面的素材，能够变成an interesting conversation with a stranger，因为任何游览的话题，都能够给“司机大哥”整点儿台词加点儿戏啊!
I’d like to talk about the time I talked to a taxi driver in Tibet.
It was about 2 years ago, my mom and I took a trip to Tibet. When we arrived there, we grabbed a taxi near the train station. And the driver was so talkative and hospitable. He recommended a lot of tourist attractions to us.
We asked him whether there’s any unique activities we could do on the grass besides sightseeing, and he said, if we are interested, we could try horse riding.
But he also gave us a heads-up, he warned us to be careful and not to be ripped off by those greedy people who tend to overcharge tourists. For example, usually the price is 30 RMB for a ride, but they would ask 60 for it.
So, you see, it was a great talk, I mean, he’s like a free guide, you know. With his help, we saved a lot of time and of course, money as well.
grab = to have or take something quickly, especially because you are in a hurry例如：
Let's grab a sandwich before we go.
I'll grab a bite to eat in town.
Grab a cab and get over here.
I managed to grab a couple of hours' sleep on the plane.
Grab a seat, I won't keep you a moment.
heads-up = a piece of information given in advance of something or as advice例如：
Send everyone a heads-up about the changes well in advance.
Can anyone give me a heads-up about how to change the format?
This is a heads-up about the seminar this week.
His statement said that he was not given a heads-up about the FBI raid.
ask something (for something) = to request a particular amount of money for something that you are selling 例如：
He's asking £2 000 for the car.
How much were they asking for their house?
This topic reminds me of the time I saw lots of people smiling when I was visiting Tibet. It was about 2 years ago, my mom and I took a trip to Tibet.
