Ah, I've found a interesting way to make use of Google Translate for English writing exercise. You may already know this, but I didn't know it. First, you write a text in English. Then you translate the text by Google Translate into another language (Japanese). Once you've got a properly readable translation, you revert the result into English. Hooray! Now you've got a rewrite version of the text by Google the teacher himself. That is, it's a back-translation. Comparing the original and the Google Translate's is interesting and you might find it instructive and helpful. Sometimes you might learn more natural way of expressions in the English writing.

English to Japanese：

ああ、私は英語のライティング練習にGoogle翻訳を利用する興味深い方法を見つけました。 あなたはすでにこれを知っているかもしれませんが、私はそれを知りませんでした。 まず、英語でテキストを書きます。 次に、Google翻訳でテキストを別の言語（日本語）に翻訳します。 適切に読みやすい翻訳が得られたら、結果を英語に戻します。 やったー！ これで、Google先生自身によるテキストの書き換えバージョンが手に入りました。 つまり、それは逆翻訳です。 オリジナルとGoogle翻訳の比較は興味深いものであり、有益で役立つ場合があります。 時々、あなたは英語のライティングでより自然な表現方法を学ぶかもしれません。

Japanese to English：

Ah, I found an interesting way to use Google Translate for English writing practice. You may already know this, but I didn't know it. First, write the text in English. Then use Google Translate to translate the text into another language (Japanese). Once you have a properly readable translation, put the results back in English. Yay! Now you have a rewritten version of the text by Google Sensei himself. So it's a reverse translation. The comparison between the original and Google Translate is interesting and can be informative and helpful. At times, you may learn a more natural way to express yourself in English writing.

Now you can compare them:

Above, I markered some of noteworthy changes made on the original text. But I know that this method I experimented here does not warrant flawlessness as the English language. The translated meanings might badly deviate from what were intended in the original. By the way, I suspect that if you use languages grammatically more akin to English than Japanese, such as Spanish or French, you might be able to calibrate the results more finely.

Let's check the back-translation:

Hmm...
