An ecologist climbs trees in Yunnan 【小题1】 (understand) the forest canopy. The ecologist knows his way around the forest in Xishuangbanna Dai Autonomous Prefecture, Southwest China’s Yunnan province.

But it’s only half of the battle to get to the top. “I normally stay up there for about half an hour, observing insects and collecting leaves to see how many leaves 【小题2】(eat) by insects," he says. It’s part of his research into the forest canopy, 【小题3】 refers to the upper vegetation in an area, generally 【小题4】(form) by tree crowns. Different from the forest ground that is dark and humid, the canopies are more open and exposed 【小题5】 sunlight. “It plays an essential role in 【小题6】 (help) us obtain a clear picture of the functioning of forest ecosystems.”

The forest 【小题7】 (become) a home away from home for him already. 【小题8】 Nakamura’s focus has been on insect 【小题9】 (diverse) on the canopies, he also stops to check insects on the ground where he goes.

In 2013, Nakamura accepted an invitation from Xishuangbanna Tropical Botanical Garden after he finished his postdoctoral studies in ecology at Griffith University in Australia. It boasts one of the 【小题10】 (large) collections of outdoor plants in the world, which makes it an ideal place for.

Earth is most likely experiencing its sixth mass extinction. The planet has been through at least five such disaster 【小题1】 , but this is the first one in human history-and the first one with human fingerprints.

A report by the World Wildlife Fund   【小题2】 (offer) details about this decline, which has cut the planet's vertebrate(有脊椎的) wildlife populations   【小题3】 average of 60 percent in just 40 years. Habitat loss is the main threat 【小题4】 many endangered land animals. “Science shows us the cruel 【小题5】 (real) that our forests oceans and rivers are suffering at our hands now,” says Marco Lambertini, director of WWF International, in a statement. “Inch by inch and species by species decreasing wildlife numbers and wild places are an indicator of the huge influence and 【小题6】 (press) we are putting on the planet.”

“The statistics are 【小题7】 (scare), but all hope is not lost,” says Ken Norris, science director for the Zoological Society of London. The report exposes some environmental 【小题8】 (problem) around the world, but it also throws light on the ways we can still protect and recover what 【小题9】 (leave) .We have an opportunity to design a new path forward 【小题10】 allows us to co-exist with the wildlife we depend upon.

October 27 is National Black Cat Day! In honor of that, here’s how we can protect our pets on【小题1】 most frightening day of the year, Halloween! Understanding what can be dangerous for our pets 【小题2】(be) especially important during the holidays.

Best Friends Animal Society (BFAS) is here for us again! They have recommendations on how【小题3】(live) our best lives on Halloween, while still keeping our pets safe.

Candy is for kids, not dogs and cats. Chocolate can be very 【小题4】(harm) to our furry friends. Candy containing xylitol (artificial sweetener) can also be dangerous. Keep any candy out 【小题5】 pets’ reach.

Wires and cords that light up your holiday decorations can be deadly if they are bitten by pets. Please make sure pets don’t get close 【小题6】 them.

We should keep Jack-o-lanterns with lighting candles, 【小题7】 might be accidentally knocked over and potentially start a fire, away from pets.

Pets should 【小题8】(keep) inside during Halloween if trick-or-treating is happening in your community. Take care when 【小题9】(answer) the door so your cat doesn’t nun outside. If the extra door knocking or doorbell ringing troubles out your pets, put 【小题10】(they) in a quiet room away from the noise.
