中國(guó)閱兵展示強(qiáng)大軍事力量 習(xí)近平宣布裁軍30萬(wàn)

Chinese president Xi Jinping made an unexpected pledge on Thursday to cut his army by 300,000 troops, even as his armed forces put on a massive show of force during a 70th anniversary military parade commemorating the end of the second world war.
3日，中國(guó)舉行了紀(jì)念第二次世界大戰(zhàn)結(jié)束70周年的閱兵，展示了雄厚的軍事力量。中國(guó)國(guó)家主席習(xí)近平出人意料地在閱兵儀式上宣布中國(guó)將裁減軍隊(duì)員額30萬(wàn)。

In the surprise announcement in front of a gathering of some of the world’s leaders in Beijing’s Tiananmen Square, Xi said China was committed to peaceful development.
習(xí)近平在齊聚北京天安門(mén)廣場(chǎng)出席閱兵儀式的世界部分領(lǐng)導(dǎo)人的見(jiàn)證下發(fā)布了這一意外的聲明。習(xí)近平說(shuō)，中國(guó)將始終堅(jiān)持走和平發(fā)展道路。

And he pledged his country would “never seek hegemony or expansion. It will never inflict its past suffering on any other nation”.
習(xí)近平還表示中國(guó)“永遠(yuǎn)不稱(chēng)霸、永遠(yuǎn)不搞擴(kuò)張，永遠(yuǎn)不會(huì)把自身曾經(jīng)經(jīng)歷過(guò)的悲慘遭遇強(qiáng)加給其他民族?！?/p>

Language tips：

《衛(wèi)報(bào)》在報(bào)道中先后用了unexpected（意外的，想不到的）和surprise（令人驚訝的）來(lái)描述中國(guó)宣布裁軍這一舉動(dòng)的出人意料，如果用網(wǎng)絡(luò)流行語(yǔ)來(lái)說(shuō)，應(yīng)該是：聽(tīng)說(shuō)中國(guó)要裁軍30萬(wàn)，當(dāng)時(shí)我就震驚了！

Commit to是固定詞組，commit yourself to something表示你會(huì)全身心投入做某事，而如果說(shuō)commit yourself to someone, 則表示承諾與某人建立長(zhǎng)期戀愛(ài)關(guān)系。
