As a nature photographer, I enjoy     1     (work) outside in the wild. One of the best things about this job is that you can see animals in their     2     (nature) environments.

My favorite place to take     3     (photo) is Yellowstone National Park. As the world’s first national park, it is     4     (probable) best known for its bears. Although the bears have a     5     (weigh) of up to 300 kilograms, they are good runners and excellent swimmers.

Last spring in Yellowstone, I followed a path     6     took me through a dark forest. When I finally stepped out of the trees, the view was amazing. While I     7     (concentrate) on photographing this scene, I suddenly had a feeling that I was being watched. Slowly, and with the camera still held to my eye, I turned and was frightened. Only metres away from me was a bear. With water falling off     8     (it) thick, brown hair, the bear stared back     9     me. Time stood still as the bear and I both waited     10     (see) who would move first. My legs started shaking. Somehow, I forced my finger to press the button. Luckily, a second later, the bear turned and ran back into the forest.

Over 100 students had been persuaded     3     (stop) using social media for seven days, most of whom     4     (be) excited and nervous.

Doing the detox not only     6     (make)Devon realize the value of     7     (really) contact but also motivated Cindy to visit a different friend every day.

China has a large number of Chinese dishes, a wide range of flavors, and complex cooking methods, which are     1     (two) to none in the world.

You probably have ever been warned against using certain hand gestures when     1    (travel) abroad. The meanings of hand gestures differ so     2    (great) in different countries. But do you know the relationship between body language     3     groups?

Mark Mofftt, author of The Human Suarm, describes our need to belong to a certain group. We are     4    (safe) in a group than in one person. We trust them, they protect us, and they share     5     same values and beliefs as us. We will even go to war     6    (fight) for our group.

Humans gravitate (吸引) to those people who are     7    (member) of their own group. This is because we like to be able to predict the actions of others and belonging to a group enables this.

There are many things help us identify these strangers or outsiders-the clothes they wear and the way they speak. Now, experts know that their body language is also an indicator. In our ancestors’ times, knowing     10     someone is a friend or foe (对手) could mean the difference between total annihilation (灭绝) of their family or the survival of their genes.
