A lot of primary school students like playing with toy planes.Many of them bought toy planes. Actually， toy planes can be madeby themselves.

很多小學(xué)生喜歡玩玩具飛機。他們中的許多人買了玩具飛機。事實上，玩具飛機可以自己制作。

1. Materials youll need 所需材料

A sheet of paper — a standard 21.0 cm × 29.7 cm sheet works we.ll

一張紙——一張標(biāo)準(zhǔn)的21.0 厘米× 29.7 厘米的A4紙就可以。

A flat， clean surface to work on.

一個平整、干凈的臺面。

2. Instructions 制作步驟

① Start with a blank sheet of paper： Lay the paper on the flat surface.

從一張白紙開始：將這張白紙放在平整的臺面上。

② Fold in half： Fold the paper in half vertically， aligningthe shorter edges. Make sure theedges and corners are lined upneatly.

對折：將紙縱向?qū)φ?，紙張的短邊對齊。確保紙張的邊緣與四角整齊對齊。

③ Unfold the paper： Open the paperback up so that its flat again.

展開紙張：再次展開紙張，使其變平。

④ Fold the top edges： Fold the top cornersdown to meet at the center crease， creating a triangleshape. The top of the paper should now resemble anarrowhead.

將紙張頂部邊緣對折：將紙張頂部的兩個角沿中心對折線對折，創(chuàng)建一個三角形形狀。此時，紙張的頂部應(yīng)該像一個箭頭。

⑤ Fold in half again： Fold the paper in half once morealong the original center crease. The top of the paper nowresembles a narrow arrowhead.

再次對折一半：再次將紙張沿原中心對折線對折。此時，紙張的頂部像一個窄一點的箭頭。

⑥ Create wings： Fold the paper in half backwards alongthe original center crease to create the wings. Make sure theedges align with the center crease.

制造機翼：將紙張反方向沿原中心對折線對折，創(chuàng)建機翼。確保邊緣與中心對折線對齊。

⑦ Final adjustments： After making the wings， you can?fine-tune your paper plane by ensuringthe wings are symmetrical， and the body isstraight. The back should form a horizontal line.You can also slightly bend the rear edges of the wings upwardfor stability.

最后調(diào)整：制作機翼后，你可以通過確保機翼對稱、機身筆直來微調(diào)紙飛機。機身的后部應(yīng)形成水平線。你還可以稍微向上彎曲機翼的后緣以提高穩(wěn)定性。

⑧ Ready to fly： Your paper plane is now complete！ Holdit at the back， right below the wings， and give it a gentle toss.Experiment with different throwing angles and amounts of forceto see how far and straight your paper plane can fly.

準(zhǔn)備飛行：你的紙飛機現(xiàn)在制作完成！握住它的后部，就是機翼下方的位置，然后輕輕扔出去。嘗試不同的投擲角度和力量看看你的紙飛機能夠飛多遠(yuǎn)、多直。

Feel free to customize your paper plane with differentcolors， designs， or additional folds for added aerodynamics.Making and flying paperp l a n e s i s n o t o n l y a nenjoyable pastime but also agreat way to explore basicprinciples of aerodynamics.Have fun and happy flying！

你可以根據(jù)你的喜好使用不同的顏色、設(shè)計或額外的折疊以增加其空氣動力學(xué)性能來定制你的紙飛機。制作和飛行紙飛機不僅是一種愉快的消遣，還是探索空氣動力學(xué)基本原理的絕佳方式。玩得開心，快樂飛翔！
