"There are easily obtained from office supply stores that provide the most commonly used items under one roof." 請問"under one roof"是甚麼意思呢?

under one roof = under the same roof It means “in the same building or home”. ex: Here we can buy food, clothes, stationery all under one roof. (在這裡你可以在同一個地方買到食物、衣服以及文具) ex: If two persons are going to live under one roof, they need to get along. (如果兩個人要住在同一個屋簷下，那他們必須要處的來。) There are easily obtained from office supply stores that provide the most commonly used items under one roof. 他們能很容易在一個能在同一賣場內提供使用最普遍項目的辦公室用品店內找到。

這一題應該是印刷的錯誤，原題應為：Now I’ll never RETRIEVE MY ten-year pin because it rolled behind the refrigerator. 現在我將無法取回我的用了10年的胸針，因為它滾到冰箱後面去了。

這一題的答案就是(D)valid -- 合法的、有效的 adj. (A) validity -- 正確性, n. ( validation -- 批准、確認 n. (C) validate -- 確認、證實 v. 根據題目，在出國前，要確定有有效的護照(不能過期)。

up front adv 或 adj 指預先、事前、在前面，甚至指直截了當地 eg. up-front salary 預付薪資

’under one roof’ = all in one place For example, ’I enjoy shopping at SOGO department store because I can find everything under one roof. Whether I am looking for shoes, clothes, make up, or food, it can all be found here, under one roof. I hope that helps. Cheers.
