【题目】Octopuses (章鱼) are sea animals famous for their rounded bodies, bulging eyes, and eight long arms. They live in all the world’s oceans but there are especially more octopuses in warm, tropical (热带的) waters. Octopuses, like their cousin, the squid (乌贼), are often considered “monsters of the deep”, though some species, or types, occupy relatively shallow waters.

Most octopuses stay along the ocean’s floor, although some species are pelagic, which means they live near the water’s surface. Other octopus species live in deep, dark waters, rising from below at dawn and dusk to search for food. Crabs and shrimps rank among their favorite foods, though some can attack larger prey (猎物), like sharks. Octopuses typically drop down on their prey from above and, using powerful suctions that line their arms, pull the animals into their mouths. The octopus performs its famous backward swim by blowing up water through a muscular tube on the body called a siphon. Octopuses also crawl () along the ocean’s floor, putting their arms into small openings to search for food Seals, whales, and large fish prey on octopuses.

If threatened, octopuses shoot an inky liquid that darkens the water, confusing the other animals. The octopus can also change to gray, brown, pink, blue, or green to mix with its surroundings. Octopuses may also change color as a way to communicate with other octopuses. Octopuses are solitary creatures that live alone in dens (巢穴) built from rocks, which the octopus moves into place using its powerful arms. Octopuses sometimes even fashion a rock “door” for their dens that pull closed when the octopus is safely inside.

A short guide to surviving a post-election Thanksgiving

Thanksgiving in the US is a celebration of the blessings of the previous year. This time it included one of the most divisive presidential campaigns. Even now it is over, the possibility of argument has not disappeared. Here we have some tips for you to survive this Thanksgiving.

●Cover up any signal of union

It might be fine to have your Hillary bumper sticker in New York, but it isn't going to go down well in Wyoming, where 70% voted Trump. Similarly, your "I love Trump" T-shirt will probably not be popular in California, where 62% voted Hillary.1

●Practice your facial expression beforehand

They say a picture tells 1,000 words. Your face is the same. 2You need to invest some energy in making sure your true feelings are completely buried. Ten minutes in front of the mirror should be enough to perfect your neutral face. 3Well, we suggest closing them. Easy.

●Have a list of neutral topics for the dinner table

The weather is A favorite subject of the British. It is inoffensive, bland and can provide a good half-hour's chat, if done well. Everyone has an opinion on whether or not it is colder/hotter/wetter/windier than last year/10 years ago/when they were little. You can involve the whole family.4With Clinton and Trump supporters largely split on whether climate change exists, it could inadvertently lead to politics. So it's maybe trickier for Americans than the weather-worn Brits. 5After all, the rivalry between your American football team of choice and your cousin's may have a long and vitriolic history, but it is likely to be less poisonous than the current differences in your politics.

A. Sports may not be a neutral subject.

B. Biting your lip is simply not enough this holiday season.

C. There are hundreds of outstanding topics for Thanksgiving.

D. There is one slight downfall to this particular favorite.

E. Are you one of those people whose eyes always tell the truth?

F. So we advise leaving the T-shirt at home, and covering up the stickers.

G. It would be fine, if people of different opinions would not spend Thanksgiving together.
