歡迎閱讀《週日科學版》！我們每週日都要為你介紹可以在家中進行的有趣科學實驗。你可以在《科學日誌》中記錄自己做了哪些活動，這樣就可以將所學的紀錄下來，比較這些結果，也許還可以利用它們來設計新的實驗！先看一下《科學日誌》的點子再開始吧。展開實驗之前，記得要獲得大人許可喔！
Have you ever wondered if plants lose water from their leaves? This week we're going to do an experiment to find out.
What you will need:
Various kinds of leafy plants

Small plastic bags or ziplock bags
Tape (optional)
▲ Before you start, note that this works best on plants exposed to the sun.
▲ Put a plastic bag around one leaf on each plant. Close the bag in such a way that water won't be able to easily escape. Be careful not to crush the stem of the leaf.
▲ Close another bag and leave it to one side. This is your control.
▲ Periodically take a look at the bags. Note how much moisture appears in each of the bags.
▲ After a couple hours, take the bags off the plants and record your observations.

你是否曾想過植物內的水分會不會從它們的葉子流失呢？這個星期，我們將要做實驗來驗證。
所需材料︰
各類多葉植物
小塑膠袋或是封口袋
膠帶（可有可無）
▲實驗以前，請注意：如果將植物暴露在陽光下，實驗效果會最好。
▲將塑膠袋套在每一株植物的其中一片葉子上，然後將袋口封好，讓水氣不容易跑掉。請小心不要把葉柄給壓壞了。
▲將另一個塑膠袋也封好，然後放置一旁，作為對照組。
▲定期觀察這些塑膠袋，注意每一個袋子有多少水氣出現。
▲數小時後，將塑膠袋從植物上拿下來，並記錄所觀察到的現象。

炎炎夏日氣溫節節升高，全球暖化造成的極端氣候正在影響世界各地。自六月以來，熱浪襲捲歐洲各地，許多國家都出現了超過攝氏40度的高溫，就連台灣氣溫也是屢創新高。暑假出國如果不小心中暑的話，學會這些英文單字才能和外國人描述症狀喔！ heat exhaustion熱衰竭 熱衰竭的英文是heat exhaustion，exhaust (v)有多重意思，可解釋為「使精疲力竭」或是「用完、耗盡」，另外還有「廢氣」的意思。 We felt exhausted after a long journey. （在長途旅行後我們感到筋疲力盡。） To find the resolution, we’ve exhausted all our resources. （為了尋找解決方式，我們已經用盡了所有資源。） One of the culprits of air pollution is car exhaust fumes. （汽車廢氣是造成空氣污染的罪魁禍首之一。） exhaust的形容詞是exhaustible「窮盡的」，經常與exhaustive (adj)搞混，這裡的意思為「徹底的、完整的」，是多益測驗的重要單字，常和study／research 搭配，例如(an) exhaustive study／research「完整的研究」。 heat stroke中暑 中暑（heatstroke）比熱衰竭更為嚴重，stroke解釋為「中風」，但是要注意stroke也是strike的過去式。strike當動詞有「打，襲擊」的意思，當名詞時則是「罷工抗議」。 If someone you know shows signs of a heat stroke, first, take him/her to a shaded area. （如果你認識的人出現中暑的症狀時，首先將他移至陰涼處。） A magnitude 4 earthquake struck the island. （島上發生了一次四級地震。） 熱傷害的症狀 熱衰竭和中暑常伴隨著許多症狀，例如昏眩（dizziness），嚴重頭痛（severe headache）、疲倦（tiredness）、噁心（nausea）、嘔吐（vomit）、肌肉痙攣（muscle cramp）…等，如果身旁友人全身發熱，卻沒有出汗（no sweating），但說出意識不清的話，則需要儘快就醫，這些單字在向醫生描述症狀時都非常實用。 sweat「流汗」可當動詞和名詞使用，但是口語上常聽到的no sweat 並不是「沒有出汗」，而是「沒問題、不費力」的意思。 We were covered in sweat after we finished an hour of Zumba. （跳完一個小時的尊巴舞後，我們汗流浹背。） A: Can you help me move the desk? （你可以幫我搬那張桌子嗎？） B: No sweat! （沒問題！） vomit (v)「嘔吐」的同義字是throw up，嘔吐前常有的噁心感可以用形容詞nauseous或sick to one’s stomach來表示。 “You could feel your heart rate increase rapidly without doing any
US Pesident Joe Biden signed into law a broad competition bill Tuesday last week that includes about US$52 billion to boost domestic semiconductor research and development, calling it a “once-in-a-generation investment in America itself.” “We need to make these chips here in America to bring down everyday costs and create jobs,” said Biden at a signing ceremony for the CHIPS and Science Act on the White House South Lawn, joined by executives from US semiconductor firms and congressional leaders. Biden said he had visited the US facility where Javelin missiles were made and said the bill would make the nation less reliant
Vegan violins 非動物製品！全球第一把「純素」小提琴 Recently, veganism has been steadily gaining steam. This lifestyle choice __1__the use of animal-based products, especially when it comes to one’s diet and clothing. However, animal products are used in such a wide range of __2__ that living as a true vegan can prove to be a difficult challenge for many people. Those who play the violin, for example, have traditionally had no __3__ but to use instruments that rely heavily on glues made from the skin, bones, and tendons of animals to hold them together. Fortunately for these vegan musicians, however, this is no longer the case. Padraig O’Dubhlaoidh, an
