解析：⑴Withthedevelopmentof意為“隨著...的發(fā)展”。

(2)表示人工智能廣泛的應(yīng)用范圍，可以使用丘om…to…。

⑶Inreality意為“實(shí)際上,事實(shí)上

(4)Herearesomeof...用來(lái)舉例說(shuō)明。

(S)individuallearningneeds意為“個(gè)性化學(xué)習(xí)需求”。

(6)streamlineadministrativetasks意為"簡(jiǎn)化管理任務(wù)”。

2.中國(guó)的官方語(yǔ)言普通話(Mandarin)在美國(guó)的學(xué)校中突然熱起來(lái)。由于中國(guó)

經(jīng)濟(jì)在21世紀(jì)的快速發(fā)展，美國(guó)的公立和私立學(xué)校紛紛在外語(yǔ)課程中加入漢語(yǔ)

這一科目，或?qū)⒁延械臐h語(yǔ)教學(xué)項(xiàng)目進(jìn)行擴(kuò)展。據(jù)統(tǒng)計(jì)，在美國(guó)的學(xué)校中，有5

萬(wàn)名孩子在學(xué)習(xí)漢語(yǔ)。但推動(dòng)漢語(yǔ)項(xiàng)目的發(fā)展不是沒(méi)有遇到困難。由于缺乏受過(guò)

專業(yè)訓(xùn)練、持有證書的教師，一些學(xué)校很難加入漢語(yǔ)教學(xué)的競(jìng)爭(zhēng)。當(dāng)學(xué)校聘用教

師時(shí)，它們通常直接從中國(guó)招聘，這種方式為文化沖突埋下了隱患。

解析：mechanisms的意思是“機(jī)制，機(jī)能”，此處指光線照射、饑餓感和新

陳代謝三者之間的“作用機(jī)制:故本題選N。

參考譯文

最新的研究表明，在夜晚使用電腦或者智能手機(jī)可能會(huì)讓我們的體重增加好

幾磅。這項(xiàng)研究發(fā)現(xiàn)接觸智能手機(jī)和平板電腦發(fā)出的藍(lán)光會(huì)增加饑餓感。并且，

被此光線照射會(huì)增加數(shù)小時(shí)的饑餓感,甚至是剛剛吃過(guò)飯的人,饑餓感也會(huì)增加。

這項(xiàng)來(lái)自美國(guó)的研究結(jié)果顯示，相對(duì)于昏喑的光線輻射來(lái)說(shuō)，在被明亮藍(lán)色光線

照射15分鐘后，饑餓感便會(huì)開(kāi)始增加。這種饑餓感在飯后近兩小時(shí)內(nèi)都會(huì)存在。

同時(shí)，藍(lán)光照射已被證實(shí)會(huì)減少夜間的困意，從而增加患失眠癥的風(fēng)險(xiǎn)。

研究者之一，來(lái)自芝加哥西北大學(xué)的張艾薇稱：“夜晚被明亮藍(lán)光照射三個(gè)

小時(shí)，會(huì)對(duì)饑餓感和葡萄糖代謝有著極大的影響。”“該研究之所以意義重大，是

因?yàn)槠浣Y(jié)果表明，控制人體周圍環(huán)境的光線照射或許是一種可左右飲食攝入方式

和新陳代謝的新方法。”實(shí)驗(yàn)的研究對(duì)象是10位有著規(guī)律睡眠和飲食時(shí)間的健康

成年人。在研究期間，研究對(duì)象每日攝入完全相同的高碳水億合物食物。他們?cè)?/p>

昏暗光線環(huán)境下完成了一個(gè)為期四天的實(shí)驗(yàn)：在每日16小時(shí)的清醒狀態(tài)下接受

低于20勒克斯的光照，而在8小時(shí)的睡眠期間接受低于3勒克斯的光照。第三

天，研究對(duì)象在起床10.5小時(shí)后的3小時(shí)內(nèi)受到了260勒克斯的明亮藍(lán)光照射，

然后將其實(shí)驗(yàn)結(jié)果與實(shí)驗(yàn)第二天用昏暗光線照射的結(jié)果進(jìn)行了對(duì)比。

張女士表示，光線照射、饑餓感和新陳代謝三者之間的作用機(jī)制仍然需要進(jìn)

一步的研究證明。
