取り組み日 再点 月 目標時間 STEP3 読解問題にアプローチ (2年7月改) 20分 The Latin word infans, from which “infant" comes, means "a person who is unable to speak" But all mothers know that communication begins long before actual speech. Babies “talk" to parents with their eyes, their expressions and their whole bodies, and parents respond to them in the same language. Human beings are different from other animals in our highly developed use of language and understanding. Ababy can hear conversations even while she is in her mother's womb. And then from the minute she is born she begins to feel the rhythms of her native language and gradually learns to recognize meaning. In South Africa, *the Bantu tribe celebrates the first time a child answers to her name witha special dinner. The best way to encourage your baby's language is to begin a two*way conversation. Mothers all over the world talk to their babies in a special language, known as "(ア)motherese" or “baby talk". Without learning how, we tend to use the simplest words, changing our grammar to make sentences shorter. Mothers talk of themselves in the third person, repeat things, and speak to their infants in a sing-song pitch. By looking at our babies while we are talking to them, we also teach them the facial expressions that come with speech. Babies start babbling from around three months, repeating easy sounds like “da", “ta", "ma", “ba" and “pa”. All around the world these first basic sounds are the roots of common names for other family members, most importantly “mother" and “father". For example, baba means “mother” among *the Gusii tribe of Kenya, while baban is “father" for *the Sambarivo people of Madagascar. The English word “daddy" is tata in Greek, tatasin Sanskrit and papa in French. Considering the amount of time she spends with her baby in the first months, a mother might expect her baby to say her name first. But this doesn't usually happen. Studies have shown that (イ)babies try to name their fathers before their mothers. Perhaps mothers want to hear their baby's first word as “daddy", in order to make a father feel more important and to add more meaning to his fatherhood. Or perhaps father, a familiar but often a little more distant person, is considered worth saying first. In Europe, the origins of the everyday words for “mother" are closely related to breastfeeding. Mom, Mam, Mummy - all these words come fronm the ancient Greek mamman, which means 17

解答では背理法を使っているのですが、この証明方法でも大丈夫でしょうか?

117 次の等式を満たす有理数 p, qの値を求めよ。 第2章 集合と命題 29* 113 実数 x が正の無理数であるとき, /x は無理数であることを証明せよ。 STEPくB 例題 13 nは整数とする。次の命題を証明せよ。 n°が3の倍数ならば, nは3の倍数である。 対偶を証明する。3の倍数でない整数nは, 3k+1, 3k+2(kは整数)のいずれかの 形で表される。 対偶「nが3の倍数でないならば, n° は3の倍数でない」 を証明する。 nが3の倍数でないとき, nはある整数えを用いて 3k+1, 3k+2のいずれかで表さ 指針 解答 れる。 こ de [1] n=3k+1のとき n=(3k+1)°=27k°+27k°+9k+1=3(9°+9k°+3k)+1 9°+9k°+3kは整数であるから,n°は3の倍数でない。 12」 n=3k+2 のとき ケ効半ふ 変 n°=(3k+2)°=27k°+54k°+36k+8=3(9k°+18k?+12k+2)+2 9°+18k°+12k+2は整数であるから, n° は3の倍数でない。 よって,対偶は真である。したがって,もとの命題は真である。終 114 m, n は整数とする。次の命題を証明せよ。 (1) n?が5の倍数ならば, nは5の倍数である。 *(2) mn が3の倍数ならば, m, nの少なくとも一方は3の倍数である。 115 V6 が無理数であることを用いて,V3-V2 は無理数であることを証明せ 太関 よ。 T16 p, gが有理数,Xが無理数で, か+qX=0 であるならば, カ=q=0 であるこ とを証明せよ。 =1 1)0ta?=2+V2 2-1
