We walked inside a museum in Garden City and looked around, eager     1     (meet) Kobie Boykins, a NASA engineer. He helped to design the Mars rover (探测器) Curiosity,     2     is still exploring to this day.

In a big presentation room, Boykins     3     (talk) about the team’s newest rover, Mars 2020. We asked him if the new rover would be     4     most complicated one he and his team     5     (make) so far. He told us that most of the engineering would be the same. However, the rover is still more       6     (advance) and will be able to get more accurate test       7     (result).

When Boykins finished his presentation, some people brought him into another room where we would interview him. We asked if he felt he was       8     a lot of pressure at work. He told us that he       9     (actual) put a lot of pressure on himself. He said that working on the spacecraft wasn’t putting him in that position, but he still wanted to make       10     perfect.

【推荐3】Zoos are some of the most     1     (delight) places children, and even adults     2     all ages love to visit. Zoos are more than just a place of entertainment and education for people, but also a place     3     animals are kept in safe enclosures. Zoos allow us to enjoy     4     (view) animals     5     we would have to make a trip to Africa to view them.

My first trip to the zoo     6     (be) years ago during an elementary school trip. That was the first time I had found myself close to wild animals like tigers, lions, giraffes and zebras. The last time I visited the zoo was about a year back when I took my kids there. Children especially are     7     (interest) in such animals on display and in terms of     8     (education) value. I would say that the trip was worth every minute     9     (spend). However, there are some of us who feel that animals shouldn't be kept in enclosures, but should rather be let out in the wild. Some feel that keeping animals in enclosures is a form of cruelty. But looking at it from another perspective,   the same animals may not survive this far had they been left on their own in the wilderness because of the     10     (present) of their enemies.
