Last week，we talked about the conflict(冲突)between sleepy teenagers and early morning classes.Many people commented on our website.

For example，Damla Ece in Turkey wrote：I agree with the idea of starting lessons later so teenagers can feel better in the morning.But sleeping more than seven hours can be wasting time for students.

Tran in Vietnam disagreed：I think teenagers，on average，need eight to ten hours of sleep every day.It's useless to try to force them to concentrate while they can't concentrate.

Afshin Heydari from Iran wrote：Schools should start early to avoid heavy traffic later in the morning.

And Suze from Jordan wrote：When I was a teenager，I enjoyed taking my courses as early as possible.That way I could find a long time in the day to do my own activities.

But Azra from Kyrgyzstan said：The reason why schools start early here is a lack of classrooms.

And Joruji in Japan wrote：When I was a teenager，I used to get up before six to go to school，which was far from home，and I don't remember having problems.I think nowadays the Internet，TV games and cell phones make teens go to sleep later.

Thirty­year­old Kika in Spain said：In my opinion，young people are very lazy.

But Dennis Jin disagreed：For high school students in China，we must reach class at 6：20 in the morning and be back home usually at 10：00 in the evening.Then we'll have some extra schoolwork to do.Can you imagine how long could we sleep every day?

Teenagers are not the only ones who suffer.Kathy in Canada wrote：My daughter likes complaining about everything in the morning，and I know that this is from lack of sleep.I wish schools should change their start time to 8：30 or 9：00 in the morning.

And Naima Star in Libya wrote：Getting up so early in the morning and leaving the warm bed is so difficult，especially in the cold weather.It reminds me of that old song：“It's nice to get up in the morning，but it's nicer to stay in bed.”

With the trans-Tasman travel now in place, many of us are dreaming of afternoons watching sunsets fall over New Zealand’s dramatic mountains and lakes. After a long time of lockdown, it’s an appealing prospect. One great way to see the sights without breaking the bank is to rent a camper（野营车）.

“It’s amazing to see the smaller towns and learn about what happens on an orchard（果园）or a farm while staying in my camper, ” says Karen Nisbet, a 38-year-old New Zealander who has spent more than four years on the road.

If you’ve never taken a camper trip before, you might be wondering what it’s like. In New Zealand, you can camp at many places if you have the right vehicle. “To be able to camp better, your vehicle needs to be certified as self-contained, ” says Andy Ford, who runs a business renting campers in Auckland and Christchurch. “That basically means you have a portable toilet, and you’ve got water and food supply on board. ”

“There is something to check before booking, because if you camp outside a campground without the proper certification, you can be fined. Even with a self-contained vehicle, it doesn’t mean you can camp anywhere, ” Mr Ford adds. Many cities and popular tourist destinations like Queenstown often have restrictions, as do areas marked for conservation.

The good news is that it’s easy to find a place to stay. NZ’s Department of Conservation has a website you can use to search for camping sites around the country, or you could use an app.

If you’re camping, it’s important to make sure you deal with your waste properly. Many camp-grounds will have a dump（垃圾场）nearby for convenience, but you may need to plan ahead.
