Landmark English Communication III (Lesson 8)1-3

➊ I now had the key to all language, / and I was eager to learn to use it. // Children who can hear acquire language without any particular effort, / while the little deaf child must learn words / by a slow and often painful process.// But whatever the process, / the result is wonderful.

➋ From the beginning of my education / Miss Sullivan made it a practice / to speak to me / as she would speak to any hearing child; / the only difference was that / she spelled the sentences / into my hand / instead of speaking them. // If I did not know the words and idioms / necessary to express my thoughts, / she supplied them, / even suggesting conversation / when I was unable to keep up / my end of the dialogue. //

make it a practice to V：Vすることを習慣にする cf. make it a rule to V
as ～ように　would：過去の習慣　any hearing child = any child who can hear　spell：綴る　keep up one's end：役割を果たす、最後まで頑張る

➌ At first, / when my teacher told me about a new thing / I asked very few questions. // My ideas were vague / and my vocabulary was inadequate; / but as my knowledge of things grew / and I learned more and more words,/  my curiosity widened / and I would return again and again / to the same subject, / eager for further information. // Sometimes a new word revived an image / that some earlier experience had left / in my brain.

vague：あいまい、不明確な　inadequate：不十分　more and more：もっと多くの　curiosity：好奇心　widen：広がる　revive：生き返らせる、呼び起こす　some→experiences?  experience：（不可算で）[知識・技能を得るために]体験・経験すること　（可算で）[人が出会う個々の]体験・経験
