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 _________for me.

One day, my guide turned off the smooth road and took me across a _________hillside instead. We picked our way carefully when _________, a Rafflesia (大王花) popped into my view among those stones. Oh, dear! More than_________, I bent down and put my nose practically inside the flower’s core.

Nevertheless, to my surprise, it was only one of the _________during the trip.

As I _________the end of my trip, there was still something I had yet to see. We planned to hunt for most feared creature there, the saltwater crocodile, which can grow to a length of 6 meters or more. _________we shone a flashlight towards the muddy shore, little sounds _________in the darkness as if something unseen underwater had broken the_________. Taking a second look, we spotted two greedy eyes just __________the water line. As we drew near, it moved 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 __________. Don’t let work __________your life. Why not step outdoors and enjoy the wonders nature offers to you?

One day in 2012, David and Pam Brennan were walking on the shore(岸) near their house in Brunswick, Maine. Then they _________ a seal(海豹) that seemed to be stranded(搁浅的). They were _________   because the tide went out and came back in, and the seal was _________ there.

Their first _________ was to Marine Mammals of Maine (MMoME), an organization that runs a 24-hour hotline, dealing with calls about stranded sea animals. _________, a volunteer arrived. While it was _________ that the seal was healthy and just resting, the experience encouraged the Brennans to _________.

Within a year, the two had completed volunteer _________. They learned how to tell a stranded seal and studied the rules governing seal handling. When it was _________ for their first seal rescue, they were __________. “As soon as MMoME made sure that a baby seal had been abandoned(被遗弃的) and that the mother wasn’t __________, we knew what we had to do,” says Pam.

“We have transported many a seal in our car. Those rides are kind of fun and also a little __________,” David says. “Seals are easily stranded in June, so it might be warm outside, but you have to keep the seals __________. So the car’s air conditioner runs and the windows are up and the car smells like a seal.”

“We feel a great responsibility to __________ these animals,” Pam says. “And really, this is what we were put on this Earth to __________.”

Hot weather has forced dozens of commercial flights to be canceled at airports in the Southwest this summer. This flight-disturbing _______ is a warning sign. Climate change is projected to have far-reaching _______—including sea level rise flooding cities and shifting weather patterns causing long-term declines in agricultural production. And there is evidence that it is beginning to affect the takeoff performance of commercial aircraft, with potential effects on airline _______.

National and global transportation systems and the economic activity they support have been designed for the climate in which it all developed. In the aviation (航空) industry, airports and aircraft are designed for the weather conditions experienced _______. Because the climate is changing, even fundamental elements like airports and key economic parts like air transportation may need to be_______.

As scientists focused on the impacts of climate change and extreme weather on human society and natural ecosystems around the world, our research has quantified how extreme heat associated with our warming climate may affect _______ around the world. We’ve found that major airports from New York to Dubai to Bangkok will see more frequent takeoff weight _______ in the coming decades due to increasingly common hot temperatures, which can help reduce the aircraft’s weight so as to lower its required takeoff speed.

There is obvious evidence that extreme events such as heat waves and coastal flooding are happening with greater frequency and intensity than just a few decades ago. And if we _______ to reduce greenhouse gas emissions significantly in the next few decades, the frequency and intensity of these extremes is projected to increase dramatically.

The _______ on aviation may be widespread. Many airports are built near sea level, putting them at risk of more frequent ______________ as oceans rise. The frequency and intensity of violent air movement may increase in some regions due to strengthening high-altitude (高海拔的) winds. Stronger winds would force airlines and pilots to change flight lengths and routings, potentially increasing fuel ______________.

Many departments of the economy, including the aviation industry, have yet to seriously ______________the effects of climate change. The sooner, the better: Both airport construction and aircraft design take decades, and have ______________ effects. Today’s newest planes may well be flying in 40 or 50 years, and their ______________ are being designed now. The earlier climate impacts are understood and appreciated, the more effective and less costly adaptations can be. Those adaptations may even include innovative ways to dramatically reduce climate-altering emissions across the aviation industry, which would help reduce the problem while also ______________ it.
