Hujan di bukit atau gunung berkumpul dan mengalir menuruni cerun. Aliran kecil boleh bergabung membentuk sungai.
Langkah 1
Air bermula di kawasan lebih tinggi
Hujan di bukit atau gunung berkumpul dan mengalir menuruni cerun. Aliran kecil boleh bergabung membentuk sungai.
Air bermula di kawasan lebih tinggi = 水从高处开始 雨落在山上，水聚在一起，顺着山坡往下流。几条小水流会汇合，变成一条河。所以河的源头通常在高处。例子：京那巴鲁山下大雨后，山上的小溪变急，流进山下的河。注意：河不是从海边开始往山上流的。
Air bermula di kawasan lebih tinggi = water starts in higher places Rain falling on hills and mountains gathers and flows down the slopes. Small streams join together to form a river, so a river usually begins high up. Example: After heavy rain on Mount Kinabalu, little streams rush down and feed the rivers below. Watch out: A river does not start at the beach and flow up the mountain.
Langkah 2
Air terjun menunjukkan perubahan aras
Di tempat cerun sangat curam, air jatuh dari aras tinggi ke aras rendah sebagai air terjun. Arah aliran tetap menurun.
aras tinggi ↓ air terjun ↓ aras rendah
Air terjun = 瀑布 在很陡的地方，水从高的地方直接掉到低的地方，这就是瀑布。瀑布显示地面高度突然改变。水流方向始终是往下。例子：水龙头的水冲进水桶，从高处落下，好像一个小瀑布。注意：瀑布的水只会往下掉，不会往上喷回去。
Air terjun = waterfall Where the land is very steep, water drops straight from a high level to a low level. This is a waterfall, and it shows a sudden change in height. The water always moves downward. Example: Water pouring from a tap into a bucket falls from high to low, like a tiny waterfall. Watch out: Waterfall water only drops down; it never shoots back up the cliff.
Langkah 3
Sungai akhirnya boleh mengalir ke laut
Sungai mengikuti kawasan yang semakin rendah hingga ke tasik atau laut. Bentuk muka bumi menentukan laluan, bukan air mengalir naik sendiri.
gunung → sungai → laut
Sungai mengalir ke laut = 河流入海 河沿着越来越低的地方流，最后流进湖或大海。地形决定河的路线。水不会自己往上流。例子：雨水从屋顶流进水管，再流进路边水沟，最后流进河里。注意：河弯弯曲曲，是因为跟着低的地方走，不是乱流。
Sungai mengalir ke laut = rivers flow to the sea A river follows land that keeps getting lower until it reaches a lake or the sea. The shape of the land decides its path; water never flows uphill by itself. Example: Rainwater runs from a roof into a pipe, then a roadside drain, and finally into a river. Watch out: A river bends because it follows lower ground, not because it wanders randomly.

Air sungai biasanya bermula di kawasan...
Air sungai bermula = 河水的起点 题目问河水通常从什么样的地方开始。回想第1步：雨落在山上，再顺着山坡流下。想想水往哪个方向流，起点就在反方向。没有雨的地方能不能有河水，也拿来检查。例子：沙巴许多河都从内陆山区一路流到海边。注意：起点和终点别弄反。
Air sungai bermula = where river water begins The question asks where river water usually starts. Recall Step 1: rain lands on mountains and runs down the slopes. Think about which way water flows; the starting point is at the opposite end. Also check whether a place with no rain could feed a river. Example: Many rivers in Sabah run from inland mountains all the way to the coast. Watch out: Do not swap the start and the end of a river.

Air terjun bergerak dari...
Air terjun bergerak = 瀑布的移动方向 题目问瀑布的水从哪里移动到哪里。线索在第2步：陡峭的地方，高度突然改变。想想地心引力把水往哪里拉。有些选项方向相反，要逐字看清“dari”和“ke”。例子：屋檐的雨水一串串落到地上。注意：瀑布一定有高度落差，没有落差就不是瀑布。
Air terjun bergerak = how a waterfall moves The question asks where waterfall water moves from and to. The clue is in Step 2: at steep places the height changes suddenly. Think about which way gravity pulls water. Some choices point in opposite directions, so read 'dari' and 'ke' word by word. Example: Rain from a roof edge streams down onto the ground. Watch out: A waterfall always involves a drop in height; without a drop there is no waterfall.
