When Charles Strattion was five, he stopped growing. His mother took him to see the famous showman, P.T.Barnum, and thought a small person would be the perfect addition to his show. He hired Charles’ parents along with him, and they traveled around the world together.

He gave the two-foot-tall Charles a new name, general Tom Thumb. He taught Tom how to sing, dance, act, and tell jokes. When he felt Tom was ready to perform on stage, he made up ads. To stir up great interest, he said that Tom was eleven years old and had come from England.

During the show, Tom fought battles pretendedly with tall people. He also danced upon a wooden plate held by a person who was eight feet tall.

Tom’s act was very popular and brought in a lot of money. By the time Tom was an adult, he had grown very rich. He had become a billionaire at the age of twenty-five.

Fortunately for Tom, Mr. Barnum added more little people to his show, and Tom became lucky in love as well. One of the little people was Lavinia Warren, a school teacher. Tom was able to win her love, and they married.

The ceremony and reception were the talk of the town. They were attended by many rich and famous people and by about two thousand guests. Crowds filled the streets of New York to have a look at their tiny wedding carriage. The couple even met with President Abraham Lincoln on their honeymoon, just before going to live in Tom’s house in Connecticut.

Their wedding, which took place during the Civil War, provided a welcome escape from the sad problems of war. Not willing to let this bit of sunshine fade, communities throughout the country sponsored “Tom Thumb” weddings.

問題一 1.次の文を読んで問題に答えなさい。答えはそれぞれ①②③④の中から一つ選びなさい。 電灯からテレビ、洗濯機まで毎日の生活に欠かせない電気の性質、働きの学習は、理科の重要な柱になっている。しかし、教師に聞くと、決まって「電流や電圧の原理を理解させるのは( A )。」という答えが返ってくる。 広島大などの研究者が2年前、八つの中学校の一~三年生約八百人を対象に、テスト形式で実態を調べた。テスト問題の正答率は、三年生でも77%だった。誤答した生徒の多くは、乾電池が同じ一個だから明るさも同じ、と答えていた。調査メンバーの一人、小倉康さんは「授業で教わりながら、相当数の生徒は、電流、電圧の違いなどの基本部分が( B )。」と話す。電気がなかなか理解されない理由ははっきりしている。直接さわったり目で見たりすることが難しい。そのうえ、学校で正式に教わる前から、子供は自分なりの、素朴なイメージを持っている。 近年、小学生らを対象に、この素朴なイメージをさぐる( C )研究が盛んに行われている。子どもたちの誤解部分に光を当て、そこから適切な指導法を引き出すねらいだ。 乾電池から電球への電流回路(+極から出て-極に流れこむ)については、「+-両極から出て、豆電球のとこるで衝突して光る」「電流は一方向に流れるが、電球で消費され、減ってしまう」などととらえられている。見えない電流を正しくイメージさせようと、教室では水の流れや、血の流れ、電車の運行にたとえるなどして教える方法もされている。 生徒たちは、受験知識として法則を頭にたたきこんでいる。法則を広用する難しい問題もわけなく解く。しかし、真に理解しているとなると話は別だ。理系の大学生でもこれらの法則の意味をきちんと説明できる学生は少ないだろう。 「( D )」と「わかる」との大きな落差。理科教育の難しさはここにあるようだ。

( A )に入る言葉はどれですか。

A.おもしろい 

B.楽だ

C.難しい 

D.必要だ
