2 . “It will be marvelous. It will be spiritual.” This is the ________ tagline that Virgin Galactic used in 2004 to attract potential customers to its planned space tourism services. It promised that, within five years, it would take a total of over 3,000 passengers on life-changing trips in its spaceships. On July 11, 2021, after a last 90-minute delay, Virgin Galactic finally began its fulfillment of that original ________. For four minutes, its six temporarily weightless passengers, including the firm’s British co-founder, Sir Richard Branson, saw the planet against the blackness of outer space.

Back on the ground, Sir Richard called the experience “magical”. He may have ________ the fact that he was able to reach space earlier than Jeff Bezos, a fellow billionaire but much wealthier. On July 20, Bezos would go slightly higher, for slightly less time, in a vehicle that had been built by his own spacefaring company, Blue Origin.

The two tycoons (大亨) are among a growing number of ________ who believe that space tourism’s time has come. Suborbital (亚轨道的) tourism is part of a broader space economy that has rapidly grown over the past decade ________ technological advances. However, it is highly ________ that this will be true.

For now, Blue Origin and Virgin Galactic will offer ________ suborbital flights to paying customers. Blue Origin is focusing much more on the development of a large new rocket that will be used for the launching of satellites, on selling advanced rocket engines to other companies, and on bidding (投标) on NASA contracts such as the recently announced plan to send humans back to the moon. ________, Bezos doesn’t see Blue Origin as a provider of services to adventure-seekers.

Even this 4-minute suborbital travels have a(n) ________, apparently.

The business could be ________, once regular flights begin to offset (抵消) the rockets’ development costs. But how fast and by how much is ________.

Another challenge — and the industry’s biggest remaining uncertainty — relates to ________. History has shown that a disaster, ________ in the early stages of an industry, can set progress back by years.

Instead of     1     (mere) taking photos with famous landmarks,     2     (enthusiast) of this new trend eagerly explore every corner of various attractions, museums, and shops during their journeys in search     3     various stamps. They imprint the stamps, usually with single or multicolored pictures of the scenic spots or images of famous people on postcards or in travel journals, thus     4     (create) a unique memory of their travels. Free or paid, each stamp serves as a representation of the visitor’s     5     (present) at that specific location, becoming a     6     (cherish) part of their memories.

Shennongjia is a household name in China because it’s the home of the legendary “wild man”. Its folk tale spans the generations.

Between 1976 and 1981, the Chinese Academy of Sciences organized three large scale     1       (science) investigations.

6 . The United Kingdom is a land of natural beauty and history, with many of its finest attractions discovered through hiking. Now, dust off your boots, plan according to the following routes presented by a survey of senior hikers and an incredible experience will wait for you.

Wales Coastal Path

Wales is the only country in the world that has an official walking path covering its whole borders. The Wales Coastal Path is a footpath stretching 870 miles from Chester to Chepstow. Walking the whole thing might be demanding, but there are plenty of stretches that can be enjoyed over a day or two.

Southwest Coast Path

You need a fair amount of annual leave, a casual 52 days or so, to undertake this in one go. The route runs from Somerset all the way to Dorset, via rugged cliffs, cute fishing villages and surfing spots along the coastline. You can surely jump on to any point as you like, but you can't afford to miss all the pubs full of jokes and laughter on the way!

Coast to Coast Walk

This long-distance trail isn’t official, but popular in the country, taking hikers from the Irish Sea to the North Sea as it rolls into historic Robin Hood’s Bay in Yorkshire. Following local footpaths, the route takes you through three UK National Parks: the Lakes, the Yorkshire Dales and the North York Moors.

Cleveland Way

You’ll want nine days to folly complete this hike, which explores both the North York Moors and the county’s world-famous coastline. Just make sure you allow enough time to properly enjoy spots like Roseberry Topping hill and pick up a gentle afternoon walk at Whitby’s clifftop church.

7 . Last summer holiday, Aunt Emily took us to a safari park (野生动物园), not far from Liverpool.

I was very happy to go as I had never been to a safari park before. It’s a very interesting park, full of wild animals running freely.

When we got there, we bought our tickets and drove into the park. We were very excited at the thought of going to see the lions. But to get to the lions’ place we had to go through the monkeys’ land first. And that was an unforgettable experience because they climbed all over the car, ate apples and bananas, and threw all kinds of things at us. They seemed very unfriendly.

Anyway, we went on our way to the lions’ place where we had to lock ourselves in the car as we knew lions could be dangerous. A lion came up very close to us. Then it was on the bonnet (车盖). It looked calm but we felt terrified. Aunt Emily, who isn’t very brave, started to call for help. The kids started crying. Only my brother, George, stayed cool. I sounded the horn (喇叭) but nobody heard us.

In the end a guard arrived in his car, and the lion just got off our car and started smelling the guard’s hand as if nothing was the matter.

8 . Borneo is home to some of the most extraordinary wildlife. Several years ago, I decided to go there for a visit. A local person offered to be my guide, which was a great bonus for me.

As we drew near, it ________ and we saw clearly it was a crocodile. With great caution, we neared it and finally could ________ its true dimensions. It was a baby-no more than 0. 6 meter long. Aha, whatever, I could now report to the ________ back home, who had never been to Borneo, that I had ________ a hungry crocodile in the wild and lived to tell the tale.

The world out there is so fascinating. Don’t let work run your life. Why not step outdoors and enjoy the wonders nature offers to you?
