1 . If you could travel in time, where would you go? Perhaps you would watch an original performance of a Shakespeare’s play in Elizabethan England? What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you’d voyage far ahead of the present day to see what the future holds.

The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is the science fiction novel The Time Machine, which was written by H. G. Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term “time machine”, coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.

But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called “wormholes”, which could be used as shortcuts to other periods. Einstein’s theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking said you could travel into the future with a really fast spaceship—going at nearly the speed of light. Though building such a spaceship would of course be no simple task.

Even if you could travel into the past, there is something called the “grandfather paradox”. It asks what would happen if a time traveller were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveller wasn’t born, how would he travel back in time?

And would you really like to visit the future? In H. G. Wells’ book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles (触角). If that’s what’s in store, maybe we are better just living in the present day after all.

2 . Attractions for Kids with Dinosaur Fever

See the “age of dinosaurs” come to life with interactive exhibits based on real fossil evidence.

7 . What’s on your travel list for 2020? I’ve consulted several travel experts to find out the top places in the USA worth visiting in 2020.

Where: New Orleans, Louisiana

Why: New Orleans is known for its music and food scene-not to mention the festivals. It has about 130 festivals each year so there’s really no bad time to visit. Bourbon Street is the obvious choice for food, drink and jazz and it’s definitely a must-visit location, especially for first-timers to the city.

Where: Vail Village, Colorado

Why: Vail is the perfect destination for travelers looking to find almost everything in one central spot. Stay at the amazing Four Seasons Resort and Residences Vail to be steps away from Vail Village, a popular town with cobblestone (鹅卵石) streets for wandering leisurely. The country’s largest free transportation system runs frequently, making it easy to access almost anywhere from Vail Village to Lionshead Village.

Where: Hudson Valley, New York

Why: The Hudson Valley is where New Yorkers go to escape the city when they need a healthy dose of nature and relaxation. Just an hour and half north of New York City, the Hudson Valley is made up of small, impossibly charming towns, where the air is fresher and things do move slower in the mountains.

8 . If you're looking to fully experience Africa's breathtaking scenery, and have an eye for adventure, then there's only one place to be. Here, inside Africa picks four of the best hikes from across the continent.

1.Kilimanjaro

Make it to the top of Tanzania's 5,895-meter Kilimanjaro, and you'll be standing at Africa's highest point. The mountain is Africa's most-visited hiking destination, attracting tens of thousands of tourists and adventures every year.

You don't have to a technical climber to climb Mount Kilimanjaro; you just need not be pretty physically fit. There are six routes to choose from difficulty, scenery and success. No special equipment

2.Atlas mountains

The High Atlas is an impressive mountainous range in central Morocco that hosts North Africa's highest peak. Mount Toubkal, at 4,165 meters. There's a variety of routes to follow during your climb but inexperienced climbers should note that the hike through the mountain's challenging zones is quite demanding.

3.Mount Kenya

A long-extinct volcano. Mount Kenya is Africa's second-highest peak, at 5,199 meters.

Lying just south of the equator, the mountain's deep valleys and diverse wildlife will guarantee you wonderful scenery and a fantastic hiking experience.

The climb, however, to the mountain's steep ice-capped peaks is quite challenging, making it the most technical, probably, in that East African area.

4.Mount Meru

Mount Meru may forever exist in the shadow of its neighbor, Kilimanjaro, but Tanzania's second-highest mountain (4,565 meters) has its own devotees.

It's less known, but Mount Meru is for the true enthusiast who wants to experience what very few people actually do.

Mount Meru is often used by mountaineers to accustom themselves before trying to conquer Kilimanjaro, or by those wanting a hike with the local Massai.

A．To avoid big crowds of climbers.	B．To hike with the local Massai.
C．To get used to the situation.	D．To experience what most people do.

A．Kilimanjaro	B．Atlas mountains
C．Mount Kenya	D．Mount Meru

9 . I made my first visit to China in 2008 and last year, I    1    (be) lucky enough to take part in an event called “Shanxi in the eyes of foreigners.”

Shanxi is Chinese for “west of the mountains”, meaning the Taihang Mountains. For popular tourist attractions, Shanxi has Hengshan Mountain, one of China’s five sacred Taoist mountains and the Wutai Mountains, a sacred Chinese Buddhist site,    2    is on UNESCO’s World Heritage List.

The good transportation and easy access    3    Shanxi province, especially from Beijing, make it a comfortable trip. It is convenient for people to go on to neighboring Shanxi province, home of the    4    (fame) Terracotta Warriors or to Huashan Mountain. Thanks to the high-speed trains,    5    (visitor) can see such well-known places as Pingyao and the Mianshan Mountains within a day’s ride from Taiyuan.    6    (locate) south of Taiyuan, Pingyao, an Old Town with its own several-kilometer-long wall, has managed    7    (preserve) its Ming and Qing appearance.

In traveling across China and visiting its cities, towns, and tourist attractions, one can’t help    8    (see) that it’s a country heading toward the future. However, if you want to see both the historical past and the    9    (rapid) approaching future in one shot, at the same time, you should visit Shanxi with    10    it has to offer.
