Question

【題目】 What do you use to unlock your cellphone? A password? A fingerprint? Or simply a glance (一瞥)?

On Sept 12, 2017, Apple introduced its iPhone X, which has an eye-catching feature － Face ID.

With Face ID, you can unlock your new iPhone by just looking at it. It is powered by a camera system TrueDepth in the front of the iPhone X.

When the camera system sees a person’s face, it uses 30,000 unseen dots (點) to “map” (勾畫) the shape and outline of the face. A model of the face will then be created and stored in the phone.

The next time the person looks at the iPhone X, the same dots are mapped onto his or her face and compared to the stored model. If the two match, then the phone unlocks. This happens in less than a second.

Apple says the system is smart. If you change your hairstyle, put on sunglasses or makeup, or use the phone in the dark, Face ID still works.

Although the technology sounds amazing, there are still concerns. For example, will Face ID work for twins? What if someone uses a photo in front of the iPhone X?

According to Apple, the chance of others to unlock your iPhone X using Face ID is one in a million. Face ID can tell the difference between twins, but the error rating (出錯率) rises.

Apple also emphasizes (強調(diào)) that Face ID is smart enough only to work when you want it to. It only unlocks when you open your eyes and stare at(盯住) it. So the phone won’t unlock if you are just glancing at the phone to know the time. It won’t work either if someone puts the phone at your sleeping face or your photo.

【解析】

本文講述了2017年9月12日，蘋果公司推出了iPhone X，它有一個引人注目的功能——面部識別。人臉模型將被創(chuàng)建并存儲在手機中，當(dāng)人們再次看iPhone X時，相同的點被映射到他或她的臉上，并與存儲的模型進(jìn)行比較。如果兩者匹配，則電話解鎖。如果改變了發(fā)型，戴上太陽鏡或化妝，或在黑暗中使用手機，面部識別仍然有效。當(dāng)人們睜開眼睛，盯著手機才會有用。因此，如果只是瞥一眼手機，想知道時間，手機就不會解鎖。

【1】細(xì)節(jié)理解題。根據(jù)“With Face ID, you can unlock your new iPhone by just looking at it.”可知有了Face ID，只需看一眼就能解鎖新iPhone，故選C。

【2】細(xì)節(jié)理解題。根據(jù)“ A model of the face will then be created and stored in the phone…compared to the stored model. If the two match, then the phone unlocks.”可知它將用戶的臉與手機中存儲的人臉模型進(jìn)行比較，故選A。

【3】推理判斷題。根據(jù)“Apple says the system is smart. If you change your hairstyle, put on sunglasses or makeup, or use the phone in the dark, Face ID still works.”可知如果改變了發(fā)型，戴上太陽鏡或化妝，或在黑暗中使用手機，面部識別仍然有效，所以排除A、C、D；根據(jù)“It only unlocks when you open your eyes and stare at(盯住) it. So the phone won’t unlock if you are just glancing at the phone to know the time. ”可知如果只是瞥一眼手機，想知道時間，手機就不會解鎖，故選B。

【4】詞義猜測題。根據(jù)后文“For example, will Face ID work for twins? What if someone uses a photo in front of the iPhone X?…but the error rating (出錯率) rises.”可知iPhone X還存在一些隱憂，故選B。

【5】主旨大意題。根據(jù)“On Sept 12, 2017, Apple introduced its iPhone X, which has an eye-catching feature － Face ID.”可知2017年9月12日，蘋果公司推出了iPhone X，它有一個引人注目的功能——面部識別，后面主要講的Face ID的相關(guān)用法等，所以主旨是面部識別是一個解鎖iPhone X的程序，故選D。
