雖然葉柄、莖和葉腋在地上茁壯成長,但根部將植物穩定在土壤表面以下。根的主要功能是吸收水分、將養分傳輸到莖部並固定植物。在非閏年,二月正好有28天,而列出的其他月份各有31天。這是一個經典的腦筋急轉彎問題,突出了日曆事實,因為所有月份至少有28天,但通常只有二月停在那裡。鈣是建造和維持骨密度和牙釉質的主要礦物質。雖然磷也在骨骼健康中發揮作用,錳和鉀對其他身體功能也很重要,但鈣與強健的骨骼和牙齒最直接相關。"Caught" 是 "catch" 的正確過去式拼寫,常用於體育或釣魚等語境。其他選項是常見的拼寫錯誤,混淆了元音和輔音的順序。縮寫詞 "mustn't" 正確地將 "must" 和 "not" 結合起來,用撇號代替缺失的 "o"。其他變體要麼省略撇號,要麼錯誤地縮短了單詞,這是常見的語法陷阱。靜電是摩擦產生的,例如用氣球摩擦頭髮,導致電子轉移並產生電荷。水力、太陽能和電流分別指其他形式:水力發電、太陽能發電和流動電流。「圖書館」是藏書和資源建築或房間的標準拼寫。這些替代方案反映了語音拼寫錯誤,例如將「i」與「e」混淆或添加不必要的字母。五個主要食物組是水果、蔬菜、穀物、蛋白質和乳製品。糖不是核心組,但建議限制,因為它們提供空熱量而沒有必需的營養。太平洋面積超過6300萬平方英里,在馬里亞納海溝深達近36000英尺。就面積而言,它比大西洋、印度洋和北冰洋的總和還要大。所有生物都需要空氣(氧氣或二氧化碳)、水和食物(營養)才能生存和生長。石油是非必需資源,主要供人類用於能源,而不是生物必需品。曬太陽能自然地觸發皮膚產生維生素D。雖然戶外跑步可以間接幫助,但閱讀或待在黑暗中無法提供所需的紫外線,黑暗環境甚至會加劇缺乏症。柳橙富含維生素C,有助於免疫功能和皮膚健康。維生素A、B和D存在於胡蘿蔔、雞蛋和魚等其他食物中,但柳橙等柑橘類水果以其維生素C含量而聞名。滑鼠是一種指向裝置,可控制螢幕上的游標進行導航。網路攝影機捕捉影像,螢幕顯示輸出,數據機連接網路——這些都不能直接移動游標。這句話出自《獨立宣言》,該文件於1776年起草,旨在主張美國脫離英國的權利。《憲法》概述政府結構,《邦聯條例》是早期的框架,而《五月花號公約》是殖民地的協議。8乘以8等於64,這與將8加八次(8+8+8+8+8+8+8+8)是相同的。其他選項可能是錯誤造成的,例如8x6=48或8x7=56。"Promise" 是承諾或誓言的正確拼寫。選項中的常見錯誤包括缺少 "e" 或用 "i" 代替 "a",這會改變發音和意義。美國政府設有行政(總統)、立法(國會)和司法(法院)分支,以實現制衡。「議會制」是指像英國這樣的體制,而非美國的結構。電流流經電線,為汽車、電燈和電爐等設備供電。太陽能來自太陽,靜電是累積的電荷,水力是水力發電 — 電流描述的是日常電器中使用的流動類型。華盛頓特區是聯邦首都,設有白宮和國會。紐約、洛杉磯和芝加哥雖然是主要城市,但不是國家政府的所在地。火星因其表面的氧化鐵(鐵鏽)而呈現紅色。金星多雲且炎熱,木星有風暴,土星有光環——這些行星都沒有火星獨特的顏色。問號用於結束疑問句,表示詢問。句號結束陳述句,驚嘆號表示強調,逗號分隔思想——每個標點符號在語法中都有其特定作用。三角形由其三條直線邊和總計180度的角定義。正方形和長方形有四條邊,而圓形沒有邊或角。狗已被馴養數千年,用於陪伴、忠誠和協助。雖然貓、鳥和魚也是寵物,但狗擁有「最好的朋友」的文化稱號。光合作用在植物葉片中將陽光、水和二氧化碳轉化為葡萄糖和氧氣。呼吸作用是能量釋放,消化作用是分解食物,蒸發作用是水變成蒸氣。「Happy」拼寫為雙「p」並以「y」結尾,表示積極情緒。其他選項是語音錯誤,例如添加額外的「i」或交換元音。七大洲是:非洲、南極洲、亞洲、歐洲、北美洲、澳洲和南美洲。有些模型將歐洲和亞洲合併為歐亞大陸,但七大洲是標準計數。細胞是所有生物的基本組成單位,包含DNA並執行生命功能。原子和分子較小但非生命體,而器官則由許多細胞組成。喬治·華盛頓於1789年至1797年任職,為總統職位樹立了先例。傑斐遜和亞當斯是後來的總統,林肯則在內戰期間領導。除法將10分成兩個相等的5(10 ÷ 2 = 5)。其他選項可能是錯誤計算,例如10 ÷ 3 ≈ 3.33或10 ÷ 4 = 2.5。彩虹的顏色是紅、橙、黃、綠、藍、靛、紫(ROYGBIV)。棕色是顏色的混合,但不是彩虹中的光譜色調。「冷」是「熱」的反義詞,描述低溫。溫暖和溫和是中等的,而沸騰則是極熱。耳朵通過耳膜和內部結構檢測聲波。眼睛看,鼻子聞,舌頭嘗——每個都專門用於不同的感官。巴黎是法國的首都,以艾菲爾鐵塔等地標聞名。柏林是德國的,倫敦是英國的,馬德里是西班牙的。形容詞通過添加大小、顏色等細節來修飾名詞。動詞表示動作,副詞修飾動詞,代詞替換名詞。一周有七天:星期一到星期日。這是一個標準的日曆單位,五通常指工作日。蜜蜂採集花蜜和花粉,在蜂巢中生產蜂蜜。螞蟻飼養蚜蟲,蝴蝶吸食花蜜,蚊子吸食血液——它們都不製造蜂蜜。5 加 7 等於 12 (5 + 7 = 12)。這個基本算術是基礎,附近數字是干擾項。聖誕節紀念耶穌的誕生,並在 12 月 25 日慶祝。萬聖節是 10 月 31 日,感恩節在 11 月,復活節則在春季的不同時間。藍鯨身長可達 100 英尺,重達 200 噸,生活在海洋中。大象是陸地上最大的哺乳動物,但鯨魚的體型遠遠超過牠們。「Lunch」是中午用餐的正確拼寫。其他選項是錯誤的拼寫,改變了元音或添加了額外的字母,這在初學時很常見。You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
