46. What did Stephen Hawking think of artificial intelligence?

正確答案B). It might be a blessing or disaster in the making.

解題思路：定位第一段第一句話前半部分“either the best，or the worst thing...”，這就是他的想法，選項(xiàng)B中blessing or a disaster 正是對(duì)這句話的同義轉(zhuǎn)述，所以是正確選項(xiàng)。其他關(guān)于AI的選項(xiàng)都是對(duì)一部分看法，而不是整體看法，所以排除。

47. What did Hawking say about the creation of the LCFI?

正確答案C). It was extremely important to the destiny of mankind.

解題思路：定位第一段第一句話后半部分，也就and后面的句子，就是對(duì)于這個(gè)LCFI建立所做的評(píng)論“crucial to the future of our civilization and our species.”。選項(xiàng)C中的extremely important正是對(duì)crucial的同義重述；destiny of mankind 對(duì)應(yīng)原文civilization and our species。所以選項(xiàng)C是正確答案。

48. What did Hawking say was a welcome change in AI research?

正確答案A). The shift of research focus from the past to the future.

解題思路：定位文章第二段最后一句，找到welcome change 這兩個(gè)詞，可以發(fā)現(xiàn)整句話的說的是不再研究歷史，而是開始研究智能的未來，對(duì)應(yīng)C選項(xiàng)中，的past是原文history的同義轉(zhuǎn)述，所以正確答案是A。

49. What concerns did Hawking raise about AI?

正確答案D). Super-intelligence may eventually ruin mankind.

解題思路：定位第三段第一句話，同時(shí)找到concerns這個(gè)詞，后面就是對(duì)這個(gè)詞的解釋“humanity could be the architect of its own destruction if creates a super-intelligence with a will of its own,”“如果人類創(chuàng)造出有自我意志的超級(jí)智能，那人類可能成為毀滅自己的那個(gè)建筑師”，選項(xiàng)D中的ruin對(duì)應(yīng)文中的destruction，mankind是humanity的同義詞，所以正確選項(xiàng)為D。選項(xiàng)A和B都是講的人工智能可能產(chǎn)生的優(yōu)點(diǎn)所以錯(cuò)誤，C選項(xiàng)說的人工智能自我毀滅，文中并未提到所以排除。

50. What do we learn about some entrepreneurs from the technology industry?

正確答案C). They share the same concerns about AI as academic.

解題思路：定位最后一段，找到關(guān)鍵詞technology industry，代表性的企業(yè)家，也就是馬斯克也表達(dá)了對(duì)super-intelligence 的concerns，句子中的not alone in warning，also等詞都表明技術(shù)行業(yè)也對(duì)超級(jí)人工智能表示了一些擔(dān)憂。所以正確選項(xiàng)是C。ABD選項(xiàng)中內(nèi)容都是無中生有，通篇文章都沒有提到，所以逐個(gè)排除。
