We often hear of people talking about Karaoke. But what on earth it is about, it r    1    a question for many people. Karaoke is a sort of acoustic (音响的) equipment     2    was invented in Japan around the middle of the 1970’s. It means “a band without people”    3    Japanese. In     4    , it is just a music tape without words. This equipment first appeared in some     5    (公共的) houses and snack bars, and mainly for the     6    (顾客) to enjoy themselves. Most of the music in Karaoke was popular music.

Shortly after its invention, Karaoke was s    7     to the whole world. It was     8    (引进) to China and was welcomed by many people. A    9     you are not a good singer, or even sometimes you may sing out of tune, you can always enjoy     10    by singing Karaoke.

I was glad to receive your letter and am happy to tell you what I think about winter swimming.

I know that you are a sports fan and like swimming very much. I’m pretty sure you     1     swim very well. However, winter swimming     2     be dangerous. I suggest you join a swimming club and learn from a coach. Reading a book on winter swimming will also be helpful.

Go swimming every day through summer and autumn. When winter comes, swim for just a few minutes at noon every day. Do some exercises as a preparation before you swim. Otherwise, you     3     hurt yourself.

To protect yourself from possible dangers, you     4     (not) drink before swimming. If the water is very cold, you     5     (not)swim for too long.

When you go winter swimming, find a good place. It’s important to find a place where you     6     get in and out of the water easily.

Finally, you     7     (not)be too worried. If you join a club and follow your coach’s advice, you will be a good winter swimmer very soon.

Yours
