In many countries,     1     is not unusual for families of different backgrounds to live together in the shared space.     2    , in the United States, this idea may still be considered strange.

But this type of housing,     3    (call) co-housing, is gaining     4    (popular) in the United States, too. Co-housing complexes are popping up across the country. For many people, this way of life is a relief to the busy modern lifestyle. A co-housing community has     5     (private) owned houses and shared land. There is often a “common house” with a kitchen and dining room, meeting room, and maybe a workshop of library or music room. About 25 co-housing communities     6    (build) in recent years, according to a report.

A co-housing complex is a place     7     residents shop, cook, and eat together. They like     8    (it) sense of shared community. Children have other kids to play     9    , which many families like. Other residents like the feeling of living in a “ village”. Residents also say that they can live in co-housing for     10    (little) money than they would pay for nearby apartments.

BW Kafe is an unusual-looking cafe in Moscow.

BW Kafe first made international headlines last year,     1     photos of the St. Petersburg branch became popular online. Designed by Russian artist Anfisa Toshina, the inside part of the cafe looks like a picture     2     (draw) with charcoal (木炭) on a piece of white paper. It creates the false impression that you are the only 3D “object” in a two-dimensional (二维的) world. It’s a pretty nice trick (戏法),     3     one that might seem strangely familiar if you     4     (be) on the Internet sometime in the last two years.

This whole coloring book idea is     5     (actual) nothing new. It    6     (introduce) in Korea first, by the designers of Cafe Yeonnam-dong 239-20, but has since been copied by other entrepreneurs (创业者) looking to capitalize (利用) on the     7     (popular) of the design. We saw similar cafes open in Japan a couple     8     years ago, now Russia, and I believe there are many more all over the world, not to mention official Cafe Yeonnam branches.

While it may look like a copy of Cafe Yeonnam-dong 239-20, it’s a pretty well organized one. And for     9     (European) who can’t visit the Korean cafe, it’s a chance     10     (enjoy) a cup of coffee in a 2D world.

China’s first overpass for wildlife migration has already come into use. The bridge     1     (lie) over the newly constructed National Highway 214 is able to link animal habitats which are separated     2     the road.     3     (cover) with sand-much like the surrounding land, the overpass can fit in with the environment well.

It has been about two years since the national highway     4     (begin) and it was designed with environmental protection as a top priority. A project environmental engineer for the highway said the construction of these man-made corridors (通道)     5     (base) on years of observation of wildlife migration in the region. The bridge, for example, is built according to the region’s natural conditions and with     6     purpose of reducing the highway’s effect on the animals significantly. Wildlife overpasses and underpasses assist animals       7     (safe) crossing over or under busy roadways and allow them to continue to use their customary paths,     8     would otherwise be blocked.

Those passageways,with a total     9     (long) of 59 kilometers, enable antelopes and other animals to cross the railway freely. So far, China has put great effort into achieving     10     (harmony) coexistence between human development and the protection of wildlife. The Qinghai-Tibet Railway, the world’s highest railroad, has 33 underpasses for migrating animals.

In La Paz there are many roads     1     bad condition. One road in particular,     2     goes north from La Paz,     3     (consider) the most dangerous road in the world. On one side the mountains rise     4     (steep); on     5     other side there is a sheer drop. On average, one vehicle comes off the road every two weeks. The drop is so great     6    anyone inside the vehicle is lucky to survive.

Thanks to Timoteo Apaza, the death toll     7     (fall). Every morning he climbs up to the bend to direct the traffic, working as a volunteer. Before that, he     8     (have) lots of jobs. How much do you think Timoteo receives from doing it? Nearly nothing. Sometimes drivers give him a tip which is just enough for him     9     (live) on. But often they just pass by,     10     (take) the human traffic signal for granted. The reason why he does it is that he feels it is his mission in life to help others.
