As we all know that, teachers are very important to us. They not only open our eye to a wonderful world of knowledge, but also teach us how behave. It is undoubted that they are worth of our respect. We should always be grateful to them. Therefore, we ought obey the school rules. We should come to school in time and not make some noise in class when our teacher is conducting out the lesson. That is the more necessary and easiest thing which the students should do. Only by doing so can we show our really respect to our teachers.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项多余选项。

  51. It crossed New York from Buffalo on Lake Erie Troy to Albany on the Hudson River. 52 . The canal served as a route over which industrial goods could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nation's largest city.

The building of the canal was paid for entirely by the state of New York. 53  Between 1825,when the canal was opened ,and 1882,when toll charges(过运河费) were stopped ,the state collected $121,461,891.

For a hundred years before the Erie was built, people had been talking about a canal which could join the Great Lakes and the Atlantic Ocean. The man who planned the Erie Canal and carried the plan through was De Clinton. Those who were against the canal laughingly called it"Clinton' Ditch(沟).  54 . He and Governor Morris went to Washington in 1812 to ask for help for the canal, but they were unsuccessful.

Clinton became governor of New York in 1817,and shortly afterwards, on July 4,1817,broke ground for the canal in Rome, N.Y. The first part of the canal was completed in 1820. 55  . The length of the canal is 363 miles.

E. Clinton talked and wrote about the canal and drew up plans for it.

F. To dig the canal benefited Americans.

G. It joined the Great Lakes with the Atlantic Ocean.

Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.

People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.

A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them － perhaps by pulling off its leaves or by pulling it out of its pot － then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects (昆虫).

Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.

Another scientist, named Sauvin, achieved similar results to Backster’s. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.

1.Backster was surprised at the results of his studies because _____.

2.The plants sent out signals _____.

3.The scientist called Sauvin _____.

4.Which of the following is true according to the passage?
