2017 was an influential year for artificial intelligence (人工智能), not just in terms of the advancement of the technology itself, but also for the development of our understanding of AI's impact on our society.

When we talk about AI, often we focus on the belief that it is going to take away certain types of jobs. However, we often ignore the fact that this technology will also slowly spread into most of our lives.
Thanks to the development of AI, we are on the highway of IA, (human) intelligence augmentation (增强). Despite the great steps we've made in AI development and will continue to make in 2018, we are still years away from AI fully replacing human jobs. However, we are much closer to seeing the impact of AI spread into almost every job and the growth in human intelligence.
Take a doctor for example: AI will soon be able to detect and diagnose common diseases more quickly and accurately than humans. Now, doctors can spend more of their time explaining the possible diagnoses, communicating with patients and developing unique, reliable treatment plans that are most effective for each specific patient.
However, AI is so powerful and its adoption will only accelerate as it begins to help our work and allow us to focus on the parts of our job that are most important. But part of why AI is so attractive is also why it's so dangerous. That is, that same power allows AI that are making incorrect decisions to do so with greater speed and impact than humans have ever had.
This is why, as AI becomes more useful in 2018, it will also become more closely examined. 2018 will be the year when companies purchasing AI products don't just ask about the power of AI—they will make sure that it is tested carefully in advance, minimizing their potential unexpected impact.
(1)What does the author suggest in the first two paragraphs?
A.Many jobs should be replaced by AI in the future.
B.People should think more about the impact of AI.
C.AI is too abstract for ordinary people to understand.
D.People care little about the development of AI.
(2)The author takes the example of “the doctor” to explain that .
A.AI always makes right decisions
B.doctors will lose their jobs very soon
C.human intelligence grows with AI
D.humans are no better than AI in medicine
(3)What will be the focus about AI in 2018 according to the author's prediction?
A.The safety of AI.
B.The possibility of replacing humans.
C.Cost reduction.
D.Power augmentation.
(4)What is the author's attitude towards AI?
A.Indifferent.
B.Negative.
C.Doubtful.
D.Objective.

Elon Musk, perhaps the world’s most famous businessman, has a habit of making statements that stretch the bounds of believability.

On July 16th, 2019, he introduced a new type of brain-machine interface (BMI), starting from the design of a “neural lace (神经织网)”, a net of thin electrodes (电极) that capture the information from the brain. However, the electrodes must be flexible, so that they do not damage brain tissue and will last for a long time. And to make the implantation (植入) of so many electrodes safe, painless and effective, the process has to be automated.

Mr. Musk’s team does indeed seem to have made progress towards these goals. Its presentation included videos of a robot that is best described as a sewing machine. This robot grabs “threads”, and shoots them deep into the brain through a hole. The firm has also designed a chip that can handle signals from as many as 3,072 electrodes.

With all these technological breakthroughs, the firm now hopes to help people overcome such illnesses as blindness and paralysis. They designed a small device that would sit behind someone’s ear, picking up signals from the implanted chip and passing them on as appropriate. In a few years, using a brain implant to control your devices may be as prevalent as wearing wireless earphones today. Finally, Musk predicts neural lace will allow humans to be combined with AI systems, thus enabling the species to survive.

Though, as this announcement shows, Mr. Musk does have a habit of presenting himself as the hero of the human race, the idea that some machines at least will come under the direct control of human brains seems possible to be carried out. The biggest barrier to this happening will probably not be writing the software needed to interpret brainwaves, but rather persuading people that the necessary surgery, whether by sewing machine or otherwise, is actually a good idea.

1We can learn from the first two paragraphs that _____.

A.electrodes should be flexible to extend life

B.Elon Musk constantly comes up with unexpected ideas

C.a neural lace is used to store information from the brain

D.electrodes are implanted by top surgeons for safety reasons

2What does the underlined word “prevalent” in Paragraph 4 probably mean?

A.Useful.B.Common.C.Professional.D.Appropriate.

3What is the hardest part of carrying out BMI?

A.Convincing people to accept the surgery.

B.Developing devices to perform the surgery.

C.Writing the software to interpret brainwaves.

D.Informing people of the success of the surgery.

4What is the best title of this passage?

A.The Neural Lace, A New Type of BMI.

B.Elon Musk, the Hero of Human Beings.

C.Artificial Intelligence, the Way to Survive.

D.A Brain Implant, A Step to Control Machines.
