【題目】 My summer hols wr CWOT. B4, we usd 2 go 2 NY 2C my bro, his GF & thr 3: @ kids FTF. ILNY, it's gr8.

Can you understand this sentence? If you can't, don't feel too bad. Neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on Internet or mobile phones. To newcomers, it may look like a completely foreign language. So, what is the ‘translation' of the sentence above? It means: My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face. I love New York, it's great.

Schoolteachers and parents say this new form of writing is harming the English language. Increasing spelling and grammatical mistakes can be seen in students' writing. They fear the language could become corrupted（面目全非的）.

Everyone should just relax, say linguists（語言學(xué)家）. They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nunberg, from Stanford University, agrees. "People get better at writing by writing," he says, "Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than, their parents."

Linguist James Milroy says, for centuries, it is believed without exception that young people are harming the language. And you can bet your bottom dollar that when today's teenagers become tomorrow's parents, they too will think this way. Milroy argues that languages do not and cannot become "corrupted"; they simply change to meet the new needs.

However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, "I can understand Netspeak worries teachers and it's important that they get across to their pupils that text messaging is for fun, but that learning to write proper English is a must for their future."

Perhaps we should give teenagers a little more trust anyway. Erin, age 12, says, "I wouldn't use text language in my homework. Texting is just for fun"

【1】What is the main purpose of the first paragraph?

A.To give an example of a foreign language.B.To show an example of creative methods.

C.To express worries about using Netspeak.D.To lead in the topic of Netspeak.

【2】Which of the following is true according to the passage?

A.Cynthia McVey points out teenagers can deal with Netspeak properly.

B.Geoffrey Nunberg believes Netspeakers can write Standard English.

C.David Crystal thinks Netspeak helps develop the habit of writing.

D.James Milroy says that language is changing and improving.

【3】The expression "bet your bottom dollar" in Paragraph 5 means ________.

A.be fairly sureB.be greatly surprisedC.think it a pityD.find it interesting

【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.

【1】Face ID helps iPhone X users to _________.

A.take pictures more quicklyB.make their photos more beautiful

C.unlock their cell phonesD.create their face models easily

【2】How does the camera system of Face ID work?

A.It compares the user’s face with the stored face model in the phone.

B.It remembers users’ faces by taking their pictures.

C.It uses a map to store face models of its users for later use.

D.It matches the users’ faces with unseen dots stored in the system.

【3】The iPhone X users may not unlock their phones when _________.

A.they have changed their hairstylesB.they glance the phone for the time

C.they use it without turning on the lightsD.they wear makeup

【4】The underlined word “concerns” in Paragraph 7 probably means _________.

A.achievementsB.worriesC.rewardD.knowledge

【5】What is the main idea of the story?

A.We can unlock a smart phone in three different ways.

B.Apple’s iPhone X can’t tell the differences between different faces.

C.People don’t believe it’s safe to use Face ID.

D.Face ID is a program to unlock the iPhone X.
