三、阅读理解
Eln Musk, perhaps the wrld's mst brilliant businessman, has a habit f making statements that stretch the bunds f believability.
On July 16th, 2019, he intrduced a new type f brain-machine interface (BMI), starting frm the design f a "neural lace(神经织网)", a net f thin electrdes (电极) that capture the infrmatin frm the brain. Hwever, the electrdes must be flexible, s that they d nt damage brain tissue and will last fr a lng time. And t make the implantatin(植入)f s many electrdes safe, painless and effective, the prcess has t be autmated.
Mr. Musk's team des indeed seem t have made prgress twards these gals. Their presentatin includes vides f a rbt that is best described as a sewing machine. This rbt grabs "threads", and shts them deep int the brain thrugh a hle. The firm has als designed a chip that can handle signals frm as many as 3,072 electrdes.
With all these technlgical breakthrughs, the firm nw hpes t help peple vercme such illnesses as blindness and paralysis. They designed a small device that wuld sit behind smene's ear, picking up signals frm the implanted chip and passing them n as apprpriate. In a few years, using a brain implant t cntrl yur devices may be as prevalent as wearing wireless earphnes tday. Finally, Musk predicts neural lace will allw humans t be cmbined with AI systems, thus enabling the species t survive.
Thugh, as this annuncement shws, Mr. Musk des have a habit f presenting himself as the her f the human race, at least the cncept that sme machines will cme under the direct cntrl f human brains seems pssible t be carried ut. The biggest barrier t this happening will prbably nt be writing the sftware needed t interpret brainwaves, but rather persuading peple that the necessary surgery, whether by sewing machine r therwise, is actually a gd idea.
1.We can learn frm the first tw paragraphs that __________.
A.electrdes shuld be flexible t extend life
B.Eln Musk cnstantly cmes up with unexpected ideas
C.a neural lace is used t stre infrmatin frm the brain

3.What is the hardest part f carrying ut BMI?
A.Cnvincing peple t accept the surgery.B.Develping devices t perfrm the surgery.
C.Writing the sftware t interpret brainwaves.D.Infrming peple f the success f the surgery.
4.What is the best title f this passage?
A.The Neural Lace, a New Type f BMIB.Eln Musk, the Her f Human Beings

四、语法填空

2.take charge f urselves
3.is enjying the film

三、阅读理解
1.B推理判断题。根据第一段Eln a habit f making statements that stretch the bunds f believability.(Eln Musk……有一种习惯,他发表的言论延伸了可信度的范围。) 以及第二段中On July 16th,2019, he intrduced a new type f brain-machine interface(BMI)(2019年7月16日,他介绍了一种新型的脑机接口。)可知Eln Musk经常能提出前所未闻的想法,B项符合题意。故选B。
2.B词义猜测题。根据第四段中They designed a small device that wuld sit behind smene's ear, picking up signals frm the implanted chip and passing them n as apprpriate.可知,现在设计的小设备应用较为复杂。画线词所在句表述为几年后,与现在形成对比,表明这项技术会变得更为普遍和简易,就像戴无线耳机一样。故B项cmmn“普遍的”切合题意。故选B。
3.A细节理解题。根据最后一段中The biggest barrier t this happening will prbably nt be writing the sftware needed t interpret brainwaves, but rather persuading peple that the necessary surgery... is actually a gd idea.可知,最大的阻碍可能不是写软件,而是说服人们做这种必要的外科手术其实是个好主意。意在表明实施BMI最艰难的部分是说服人们接受必要的外科手术。故选A。
4.A主旨大意题。根据第二段中On July 16th,2019,he intrduced a new type f brain-machine interface(BMI)可知2019年7月16日,他介绍了一种新型的脑机接口。接下来全文围绕新型脑机接口(BMI)进行展开说明,因此可知A项“神经织网,一种新型的脑机接口”切题。故选A。
四、语法填空
1. t warn。考查固定搭配。try t d sth. “尽力去做某事”
2. the。考查冠词。此处特指新冠病毒。
3. cnfirmed。考查谓语动词的时态。根据上下文可知此处用一般过去式。
4. its。考查代词。后面的fficial Weib是名词, 所以此处用形容词性物主代词。
5. unfrtunately。考查副词。此处修饰动词短语be infected, 所以用副词形式。
6. against/with。考查固定搭配。抗击是“fight against”或“fight with”。
7. adding。考查谓语动词。本句主语是statement, the statement read“声明中写道”, 逗号后面用现在分词作伴随状语, 表示补充。
8. death。考查名词。根据前面的Li’s可知此处用名词。
9.wh。考查定语从句。此处是非限制性定语从句修饰a her, wh在定语从句中作主语。
10. nurses。考查名词复数。根据and前面的dctrs可知此处用复数。
