Hiking tours are a kind of adventure tourism. Generally speaking, these vacations focus almost entirely     1     hiking from one place to another. Hiking tours can be done as a group activity or alone.

There are many different ways of organizing hiking tours. Some people like to go out into the areas where there are very few people and travel over a long     2     (distant )from one place to another. They usually stay in hotels overnight before     3     (travel) to the next place on the following day.

Guides can make hiking trips safer and more focused. Some hikers prefer to take hiking tours without guides because of costs or because they want to challenge     4     (they). However, employing a reliable guide during a hiking tour     5     (consider) as a better choice for less experienced hikers.

The activity can be very tiring, and those     6     are new to hiking may worry that they aren’t     7     (physical) able to finish the tours. Sometimes it can be helpful for people     8     (go) to the doctor and make sure it is safe for them to choose     9     difficult hike. Sometimes, a     10     (challenge) hike can be deadly for someone having heart disease.

As long as I can remember, I’ve been interested in learning about people, places and traditions from around the world. I travelled with my dad     1     (adopt) my brother and sister on life-changing trip to Peru when I was 15 years old.     2     (immediate) my world expanded: in Machu Piccuhu I felt as if I     3     (wake) from a dream, which made me realize the     4     (possible) and endless adventures beyond my neighborhood.

In college, I spent a/an     5     (believe) term in Spain, and later in Ecuador. The travel desire resulted     6     countless trips abroad, from teaching English as     7     second language to immigrants in London, to travelling with my students in Costa Rica.

Now that I have my own family, I hope to raise my children to be globally and culturally aware. Our family looks like a mini-United Nations, with my husband     8     (come) from Mexico, and my daughters and sons from China and Ethiopia.     9     our intention was simply to expand our family, we have been enriched by our multicultural backgrounds and experiences. Each member of our family     10     (enjoy) both the trips to home countries as well as the celebrations of traditions here at home.

Some misunderstanding is putting shark populations at risk now. Thousands of sharks are dying as    1     result of people’s false beliefs.

Female sharks need males to make babies. Some female sharks have the ability     2    (produce) a baby by themselves and have young sharks without a male shark. That’s something commonly     3    (see) in plants and insects like ants and bees.

Shark fins have medical function.     4    (tradition), it     5     ( believe) that shark fin soup has health benefits and is quite special in China.     6     modern scientists point out that shark tissue(组织) can be extremely high in poison. What’s more, shark fishing kills up to 100 million animals each year, endangering several different species.

If you’re bitten by a shark, you will be a goner. You are more than twice as likely to die from a lightning strike as from a shark bite, according     7     the Florida Museum’s International Shark Attack File (ISAF). “Even if you are bitten, the large     8    (major) of people survive”, says Dr. Chapman. In fact, there were sixty-six unprovoked(无端的) shark bite    9    ( incident) around the world in 2018, only six of    10     were dangerous.
