【题目】
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.
【1】We 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
【2】What does the underlined word “prevalent” in Paragraph 4 probably mean?
A.Useful.B.Common.C.Professional.D.Appropriate.
【3】What 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.
【4】What 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.

【题目】 Some caterpillars’ warning signals (信号) may have evolved (进化) from walking. A team, writing in the journal Nature Communications, reported that the hair-like structures the living things use to make sounds evolved from legs.
The team studied caterpillars which use these structures to communicate their ownership of leaves. This means the caterpillars are able to “tell” strangers to go away without risking injury in fighting. “These are really interesting caterpillars,” said Dr. Jayne Yack from Carleton University in Ottawa, Canada, who led the research. “They make signals using hair-like structures which are on their back ends.”
The caterpillars drag these structures across the leaf to make scraping (刺耳的) sounds when strangers enter the area of their leaves. “When they make this signal, the strangers leave,” explained Dr. Yack. “It’s like saying ‘I’m here, get out of here — I already own this leaf’.”
The scientists looked at other species (物种) within the same group of caterpillars and created their “family tree”. They used chemical markers (标记物) to work out the relationship between the animals, showing which in the group were the more ancient species and which species evolved more recently. “Those more ancient species actually don’t have these sound-producing structures. They have legs that they use to walk towards strangers,” said Dr. Yack. These more ancient species, she explained, walk towards strangers and try to fight against them. “They can kill each other in the fighting,” Dr. Yack added. She said that the evolution of the scraping show had allowed the caterpillars to solve their fighting without injury. “So our idea is that these signals actually avoid harm to both sides — they solve fighting in a more ‘friendly’ way.”
The study also provides a map of an evolutionary process that many other biologists are researching.
【1】What can we learn about caterpillars’ warning structures from the text?
A.They have the same use as hair.
B.They are found in caterpillars’ heads.
C.They are used to fight against strangers.
D.They may have evolved from caterpillars’ legs.
【2】According to the text, Dr. Yack’s team did NOT ________.
A.draw a family tree of caterpillars
B.create a map to show how caterpillars evolve
C.study species within the same group of caterpillars
D.make clear the relationship between different species of caterpillars
【3】What does the underlined word “They” in the fifth paragraph refer to?
A.The ancient species.B.The chemical markers.
C.The sound-producing structures.D.The more recently evolved species.
【4】What is the main idea of the text?
A.How caterpillars evolved.
B.How caterpillars warn strangers.
C.Communication between caterpillars.
D.Caterpillars’ warning signals evolved from walking.
