It's not easy to be a spider. Scorpions have a deadly sting and mosquitoes can always fly away when they are scared, hungry or under attack. Spiders don't have a stinging tail or wings to help them to get food or stay safe.
They do, however, have something much cooler. Spiders can make silk! The silk is made in parts of their bodies called spinnerets. Some spiders use this silk to build webs.
There are many kinds of spiders and there are also many kinds of webs. Many of these webs are used by spiders to capture and hold their prey. The silk is thin and very hard to see from far away. Insects often fly into the webs without ever knowing what has happened.

But even though it is thin, the silk is also very strong and it holds the insect tightly until the spider is ready to eat it.
It may not be as easy as going to McDonald's or hot pot every time you are hungry, but it's a very cool and interesting way to get your dinner.(Lynn Steger, Staff Writer)
當蜘蛛可不簡單。蠍子有致命的毒刺,而蚊子只要受到驚嚇、飢餓或遭到攻擊都可以振翅遠飛,可是蜘蛛沒有尾刺,也沒有翅膀幫牠們覓食或保命。
不過,蜘蛛所使用的工具酷多了,牠們會吐絲!蜘蛛體內有吐絲器會製造蜘蛛絲,有些蜘蛛就以這種絲來織網。
蜘蛛有許多品種,蜘蛛網也是各不相同,蜘蛛多半用絲網捕捉並抓牢獵物。蜘蛛絲很細,從遠處很難看見。昆蟲通常飛進網子還不知道發生了什麼事。
不過蜘蛛絲雖然細,卻非常堅韌,可將昆蟲緊緊綑牢直到蜘蛛準備進食。
這可能不像你肚子餓就可以去麥當勞或去吃火鍋那樣容易,卻是非常酷又有趣的尋覓晚餐的方式。

Tangbao are one of the most internationally renowned delicacies, that win the hearts of both locals and tourists. Their charm lies in the paper-thin flour wrapper that needs to be folded evenly almost 20 times. Folding a tangbao requires skill to deal with a bulging filling and a thin wrapper. Tangbao are served in a bamboo steamer in which they are steamed, not only adding to the visual appearance, but ensuring they do not get cold before reaching the table. The best way to enjoy a tangbao is to dip it in a mixture of vinegar and soy sauce with
The Bank of Japan (BoJ) announced a seismic change in direction on March 19, hiking interest rates for the first time in 17 years. The move represents an unwinding of an ultra-loose — and maverick -- policy aimed at putting Japan’s “lost decades” of stagnation and deflation behind it. The last time the BoJ raised interest rates was in 2007, but its war against deflation began in earnest in 2013 under then-prime minister Shinzo Abe. “Abenomics” combined generous government spending and central bank monetary easing. The BoJ spent vast amounts on bonds and other assets to pump liquidity into the
Have you ever wished for an extra hour to prepare for exams or finish homework? In some countries, people actually adjust their clocks to gain or lose an hour, all for the sake of Daylight Saving Time (DST). Specifically, clocks are set forward by an hour in March and then set back in November. One of the primary reasons for implementing DST is to make better use of natural daylight so that people can reduce energy consumption. The concept originated with Benjamin Franklin in 1784 and became widely adopted during World War I. Today, this system is in place
For the first time, the US Federal Communications Commission (FCC) has fined a company for improper disposal of its defunct satellite. The satellite cable company Dish Network was fined US$150,000 because it failed to move an old satellite that was no longer in operation to a safe distance from others currently being used. The FCC had asked Dish Network to move one of its older satellites, EchoStar-7, 186 miles further from the Earth. However, the satellite had only advanced 76 miles before it ran out of fuel at the end of its operational life in 2022.
