Yet On the contrary, humans don't need animal protein to stay healthy. even though: かし~ にも関 わらず 意味 ｢しかし」 ｢~にも関わらず」 : 強めの表現 で反対・ 対照的な文を述べる際によく使用さ れる <例文> . Even though we made a promiss that we gather in the park at 9am, he didn't come there on time. 私たちは午前9時に公園で集合するという約束を していたにも関わらず、 彼は時間通りにそこに来 なかった。 (※make a promiss : 約束する、 gather : 集ま る on time 時間通りに) POINT今回紹介する ｢しかし｣ という意味を持つ 英単語の中で、 強めの表現として使用されます。 品詞は接続詞になります。 even though の後ろには文章が必要になるため、 文末に置くことはできず、 文頭 文中で使用され ます。 however : しかしながら、 とはい え 意味 「しかしながら」 「とはいえ」 : かたい表現 として、 butの代わり使用されることが多い <例文> • He really grew up. however, I'm worried about him. 彼はとても成長しました。 とはいえ、私は彼のこ とが心配です。 (※really : とても、 grow up : 成長する、 worry : 心配させる) POINTbut よりも硬い表現として使用される英単 語です。 また、 butよりも ｢しかし」 という意味が弱まっ た表現になります。 接続詞と副詞のどちらの品詞にもなります。 その ため、文頭文中・文末のどこに置いても使用す ることが可能です。

Proverbs often include animals. Let's look at some examples from two countries. The first one is from Thailand. "Don't ride an elephant to catch a grasshopper." When you are doing a small job, a big tool is not useful. The second one is from Brazil. “In a piranha-filled river, an alligator a-fill swims backstroke." Before you get in trouble, prepare for danger and protect yourself. Proverbs from different countries often include familiar local animals. Because of their images, people easily understand the messages.
