With advances in contemporary design and technology, the phones may __14__ remote controls, house keys, Game Boys, maps, flashlights, health monitors, recorders, handguns, and so on. 15 , they will be “the remote-control for life.”
答案：(A) In short
In short（簡言之）用來總結前面列舉的多項功能，得出「總之，它們會是人生的萬能遙控器」的結論。As yet（迄今為止）、By the way（順帶一提）、On the contrary（相反地）都不符合這種「總結」的語氣。
四個選項都是轉承語，你會憑中文挑一個，By the way 尤其眼熟，很容易先被選走。
這是邏輯勾環，而且線索一定要跨句才看得到。鑑別度高達 61，分開的是有沒有看出這一句在收尾。前面幾句一路在鋪陳未來手機的種種變化——外觀看不見、可以嵌進身體、功能一大堆、還能兼作各種裝置；空格這一句 they will be “the remote-control for life”（它們將成為「人生的遙控器」）是把前面那一大串收攏成一句話。把講過的內容收攏成結論，用 In short（簡言之、總之）。填進去讀成 In short, they will be “the remote-control for life”。
As yet（迄今為止）多配否定、講的是「到目前為止還沒有」，但這一句講的是未來；By the way（順帶一提）是要換一個不相干的話題，這一句不是插話而是總結；On the contrary（相反地）要求後面推翻前面，但這一句與前面完全同方向。
in short（簡言之、總之）、in a word（總之、一句話）、as yet（迄今為止，多配否定）、by the way（順帶一提）、on the contrary（相反地）、no longer（不再）。
The telephone is widely considered as the most rapidly evolving technological device today. Many experts in the field believe that future phones will not only look very different—they may not even be 11. They may be hidden in jewelry or accessories, or even embedded in the body. They will undoubtedly have a lot of additional features and 12 functions, and users may interact with them in new ways, too.
13 they are still called "phones"—a word meaning "voice" in Greek—making voice calls may no longer be their primary function. With advances in contemporary design and technology, the phones may 14 remote controls, house keys, Game Boys, maps, flashlights, health monitors, recorders, handguns, and so on.
15, they will be "the remote-control for life."
