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 (点) to “map” (勾画) 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 (出错率) rises.
Apple also emphasizes (强调) 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.

One morning, Thomas was woken from a deep sleep by a loud roaring(咆哮) noise. It sounded like a wild animal walking around under his bedroom window.
Thomas rushed over to the window. His eyes bulged(凸出) like basketballs ─ There, in the middle of the backyard, was a lion! “Amazing!” cried Thomas.
Suddenly, a giraffe poked(戳) its head through the window. It munched(大声咀嚼) the leaves from a plant by Thomas’s bed. Next, Thomas saw an elephant walk past the swimming pool and squirt(喷出) water all over Dad’s car. “Cool!” cheered Thomas. “Now I don’t have to wash Dad’s car today.”
Thomas grabbed his camera and rushed down the stairs. “ Dad, Dad, you were right!” he shouted.
