The leaf[emblemlcan also be found on the logos of many business in Canada, including Air Canada, and it is also the symbol for the Toronto Maple Leafs hockey team.

This famous by-product of the maple tree is a huge industry in the country. Everyone around the world loves maple syrup, and an estimated 85% of the world's production comes from Canada. Further, most of it comes from Quebec, one of the thirteen provinces and territories in the country. However, the history of this delicious syrup goes back before there were any provinces or a country known as Canada. Centuries before Europeans explored and settled in North America, indigenous people had perfected the process of tapping the sticky, sweet sap from the trees. It was First Nations people who taught this valuable technique to settlers.small 9101 Steeped in Canada's history, maple syrup making is celebrated as a proud tradition. As early spring brings warmer temperatures, conditions become ripe for tapping and collecting the precious sap) from the trees. Several festivals are held around Canada to mark the joyous occasion. Of course maple-flavored treats are featured, like hot (taffy served on fresh snow and eaten with wooden sticks. Local folk music and other entertainment round out the festivities and add to the light-hearted atmosphere. These festivals naturally attract plenty of tourists. botabro ollja BX 5 What is the purpose of the first paragraph? quola dinoms zie menuol 220m (A) To show how maple trees prove to be a tourist attraction. stewas able (9) (B) To explain how maple trees play a role in the Canadian history. alduon

For example, it is enjoyed in the Spanish-speaking countries of North, Central, and South America. At the same time, different countries have adapted the meal to suit their own particular tastes and preferences. In the Philippines, a colony of Spain from 1565 to 1898, the foods enjoyed at merienda are different from those eaten in Spain. Merienda in Spain features an array of snacks like olives, yogurt, fresh fruit, and sandwiches. While in the Philippines, it is more likely to feature local favorites like deep-fried bananas or stir-fried noodles with salted bread. Furthermore, in Spain, the term merienda relates to a meal eaten between lunch and dinner. In the Philippines, it can also be seen as a light meal between breakfast and lunch. Also, Portugal, Morocco, and Brazil are other countries that have their own takes on merienda. ( ) 12. What do we know about Spain from the passage?

想問這題,謝謝🙏

探究與實作:離子液體的選用 近年來,一種可再回收使用的綠色溶劑:離子液體,由於其具有低蒸氣壓、低熔點、 高極性、不可燃、耐強酸、高熱穩定性、高導電度、電化學性佳及較廣的液體溫度範圍等 特殊性質,在化學上的應用非常廣泛。此外它還是一種可依所需性質來組合不同陽離子、 陰離子的溶劑,因此離子液體溶劑也被認為是設計者溶劑(Designer Solvent)。 常溫離子液體(room-temperature ionic liquid, RTIL)是指在 常溫時以液體呈現的離子化合物。然而,我們日常接觸到的無機 鹽類,常溫下幾乎都是固體。以食鹽(氯化鈉)為例,若要作為 溶劑,至少需加熱到 801°C 以上才能使用。這是因為無機鹽的正 負離子在晶格中排列緊密,且彼此吸引力強,導致熔點極高,如 圖一所示。 負離子 正離子 圖一 無機鹽晶體結構 負離子 - 幸好聰明的科學家發現,若能使正負的堆積鬆散,可有效降低 其熔點。科學家設計出一種特殊的晶體,如圖二所示,此晶體是由 一有機物正離子及一個帶有非定域(delocalized)舖 電荷的負離子 團所組成。通常正離子是含氮的有機物如胺類、氨基化學物等,它 們的體積較金屬離子大,構造也往往無對稱性,而非定域電荷的負離子則和一般無機鹽類相 似。由於這樣的特殊晶體,晶格的引力較無機鹽弱,也就是其晶格構造不如無機鹽緊密,使 得其熔點下降,而達到常溫離子液體(RTIL)的目標。請回答 8.~10.題: 非定域(delocalized),指電子並不侷限於分子內某化學鍵上,而能在鄰近的數個化學鍵 上遊走。 共振 (改編自《科學月刊第555 期》第214頁〈液態的鹽 —— 常溫離子液體〉) 正離子 圖二 RTIL 晶體構造
