Poetry probably had     1     (it) origins in traditional folk music tens of thousands of years ago. In that era, there     2     (be) no TVs or films, and writing had not been invented, so people would sit around the fire at night and sing songs     3     (entertain) themselves. These songs reflected themes     4     the people’s daily lives, such as hunting animals or sowing crops. Since nothing was written down, over the years different     5     (version) of these songs developed, and each area would have its own versions rhythm. In addition to this, people would recite stories of past heroes. As these stories were often     6     (extreme) long, they often had rhyme and rhythm to help people remember them more easily. While in     7     beginning such songs and stories had a very simple format, over time they became more     8     (complicate) and more polished. These were no longer the works of amateurs     9     (sit) around a fire, but works of true poets who cared about their art     10     who sometimes made a living from it.

It happened late one night last summer,    1    my family was traveling in Montana. We stopped at a hotel and with the room keys, we entered our room. We kept the room dark and quickly put the kids to bed, hoping they’d have a good sleep. Then I went into the bathroom to get    2    (wash). Suddenly I caught sight of beer containers in the garbage can. Then my eyes     3    (scan) the floor and saw a black bag that looked like one of    4    (we). But it wasn’t! We were in someone else^’ room!

My husband immediately called the front desk and the waitress    5    charge responded with a cry “Oh, my God!”

We began putting all of our things back into our oversized suitcase. Suddenly, I heard someone    6    (unlock) the door, which made my heart beat wildly.

The door opened and    7    elderly man came in, shocked. We didn’t know    8    to do with the matter but luckily the waitress arrived out of breath. She cried even    9    (badly) for mistakenly giving us the wrong keys. After hearing the waitress’    10     ( explain) , the old man, my husband and I tried to comfort her. The special experience in someone else’s room made me realize that forgiveness is a kind of virtue.

9 . At first glance, SoFi looks exactly like a real fish. But if you look     1    (close), it’s not hard to spot the truth: SoFi is a robot, or as     2     (it)MIT developers call it, “ a soft robotic fish”, according to BBC news.

SoFi     3     swim, turn and change speeds just like a real fish, and more     4     (importance), it can take high-resolution photos and videos with a camera     5    (build) into its nose. The robot’s “ soft artificial muscle” is made of a type of rubber, it has two side fins(鳍)for waving,     6     its nose also hides important electrical components(组成部分).

The team at MIT developed SoFi to swim among real fish to explore where few other robots or humans can, reported the Los Angeles Times. It     7    (operate) with a waterproof video game controller by someone     8     can be up to 21 meters away.

According to its leading     9    (create) Robert Katzschmann, SoFi, pronounced like the girl’s name “Sophie”, is an abbreviation(缩写)of soft fish--- and was named     10       a girl he had a crush(暗恋)on in high school.
