Worker Ants, Army Ants—and Lazy Ants? —Jay Sailors Most people think of ants as diligent workers, constantly collecting food and building nests. Researchers have made a huge discovery about these tiny creatures: an average of 40 percent of ants in a colony are lazy layabouts.
"They really just sit there," says Daniel Charbonneau, a researcher from the University of Arizona. Charbonneau and his team made this discovery by painting the ants, putting four tiny dots of colored paint on each one in order to identify it. Then, using video recordings, they tracked the ants' movements over time.
But why were so many ants idle? Charbonneau found out by removing 20 percent of the most active workers from their colony. Within a week, the inactive workers replaced the ones that were lost. Charbonneau believes that it's the youngest ants that remain inactive in the nest, since they are the most vulnerable. When the colony loses workers, these young ants replace them.
Charbonneau's work shows that even in studying the simplest creatures, there's always more to learn. Ants may sometimes be lazy, but science never sleeps.
此說法源自十九世紀的一種舞蹈比賽稱為cakewalk，優勝者會得到一個蛋糕作為獎品，故take the cake用來指「拔得頭籌；最出色的」，但現今常用來諷刺「差到極點、比能想到還要糟」的意思。
A: I can't believe they delayed our flight again. That's the second time today! 我真不敢相信我們的班機又要延遲了。這是今天第二次了！ B: I know. And they're not even giving us a reason. I've flown on some bad airlines before, but this one takes the cake. 對啊，而且他們甚至沒有給我們理由。我以前有搭過幾次糟糕的航空公司，但這次無人能及。
你也可以這樣說：be the worst
Although higher SPFs exist, a sunscreen with an SPF of 30 is sufficient for most people. 雖然有SPF更高的產品，但對大部分人來說SPF 30的防曬乳就夠了。
The advantages of using sunscreen are obvious: it limits the painful effects of sunburn, and it can even save your life. 使用防曬乳的好處顯而易見：它能限制曬傷的痛苦影響，甚至可以救你的命。
The Statue of Liberty is one of America's most well-known landmarks. 自由女神像是美國最著名的地標之一。
Another idea for the statue was to have it holding broken chains to represent the end of American slavery. 另外一個關於雕像的點子是讓它握著斷裂的鎖鍊，代表美國奴隸制度的結束。
It is universally known that trees are essential because they provide us with oxygen. 舉世皆知樹木是不可或缺的，因為樹木提供我們氧氣。
