Pasangkan mentol dan sel kering pada pemegang masing-masing. Pemasangan yang kemas membantu memastikan sentuhan elektrik berlaku.
Langkah 1
Pasang komponen pada pemegang
Pasangkan mentol dan sel kering pada pemegang masing-masing. Pemasangan yang kemas membantu memastikan sentuhan elektrik berlaku.
mentol + pemegang | sel kering + pemegang
pasang pada pemegang = 装在座上 先把灯泡装进灯座，把干电池放进电池座。装得稳，零件之间才会接触好，电才流得过去。 例子：灯泡要顺时针旋紧在灯座里，摇一摇也不会松。 注意：灯泡旋得太松，看起来装上了，其实没有接触。
pasang pada pemegang = fit parts into holders First fit the bulb into its holder and the dry cell into its holder. A firm fit makes sure the parts touch properly so electricity can flow. Example: Screw the bulb clockwise into its holder until it does not wobble when shaken. Watch out: A loosely screwed bulb looks fitted but does not actually make contact.
Langkah 2
Sambungkan satu laluan lengkap
Gunakan wayar untuk menghubungkan sel kering, suis dan mentol tanpa jurang. Laluan mesti kembali ke sumber tenaga.
sel → suis → mentol → kembali ke sel
satu laluan lengkap = 一条完整的路 用电线把干电池、开关和灯泡连起来，中间不能有空隙。电的路要从电池出发，最后回到电池。 例子：跑操场一圈，要从起点出发再回到起点，才算跑完一圈。 注意：只接电池的一端是不够的，另一端也要接回来，电路才完整。
satu laluan lengkap = one complete path Use wires to join the dry cell, switch and bulb with no gaps. The path must start at the cell and come back to the cell. Example: One lap of the field starts at the starting line and ends back at the same line. Watch out: Connecting just one end of the cell is not enough; the other end must be joined back too.
Langkah 3
Uji suis tertutup dan terbuka
Apabila suis ditutup, mentol menyala. Apabila suis dibuka, litar terputus dan mentol tidak menyala. Bandingkan hanya keadaan suis supaya ujian adil.
suis ditutup: mentol menyala | suis dibuka: mentol tidak menyala
uji suis tertutup dan terbuka = 测试开关关上和打开 先关上开关，看灯泡亮不亮；再打开开关，观察有什么变化。只改变开关，其他东西都不动，比较才公平。 例子：比较两个地方的冰溶化快慢，冰块大小要一样。 注意：测试时不要同时换电池或换灯泡，否则不知道是哪一样造成变化。
uji suis tertutup dan terbuka = test the switch closed and open Close the switch to test whether the bulb lights, then open it and watch the change. Change only the switch and keep everything else the same so the test is fair. Example: To compare how fast ice melts in two places, use ice cubes of the same size. Watch out: Do not swap the cell or bulb during the test, or you cannot tell what caused the change.

Apakah langkah awal sebelum menyambung wayar?
langkah awal = 开始的步骤 题目问接电线之前要先做什么。回想这个单元三个步骤的次序，再检查每个选项是否安全、是否合理。 例子：煮饭前先洗米，再放进电饭锅。 注意：题目的关键字是 sebelum（之前），要选排在接电线前面的步骤。
langkah awal = the early step The question asks what to do before connecting the wires. Recall the order of the three steps in this lesson, then check whether each choice is safe and sensible. Example: Before cooking rice, you wash the rice first and then put it in the cooker. Watch out: The key word is sebelum, meaning before, so choose the step that comes ahead of wiring.

litar lengkap = complete circuit You must finish the sentence about what a complete circuit must have. Imagine electricity leaving the cell and returning to it, and ask what happens if the path is broken or a part is missing. Example: A doorbell rings when pressed because the button completes its circuit. Watch out: The finished sentence must make sense and fit the meaning of lengkap, which is complete.
