     This year, Chongqing primary schools decide to start morning classes an hour later. This will help
students feel less tired. And most primary schools will begin the first classes at about 9 o'clock in the
morning.
      The students are happy about the change.
      Liu Ming told us that his class were excited by the news on the first aay of the school. "Great!
From now on we students at Hope Primary School don't have to get up so early!" Liu said that he used
to get up at 6:40 a.m. Now he can get up at 7:50 a.m. because class doesn't start until 8:50 a.m.
     Wu Hong feels the same. She said the new timetable (时间表) was good for her health. "I used to
get up at 6:30 a.m. I had to drink coffee every night, or I would feel too sleepy to finish my homework,"
said Wu. "Now I can fin- ish it without coffee. Because I can sleep a little longer. "
      Many teachers say the change will help students learn better. "Students used to doze (瞌睡) for the
first two classes in the morning," said Huang Shan, an English teacher at No. 1 Primary School. "But
now they are active and learn much better than before. "
      But some parents are worried that more sleep will mean less learning. There used to be five classes
in the morning. Now there are only four. In fact, every coin has two sides. So does the change in the
school timetable.

I once experienced an unforgettable trip to Gloucester to see some of the world's most beautiful and exciting animals in their own habitat(栖息地), the North Atlantic Ocean.

    After a long trip by bus, we got on the ship. After a while, we stopped and everyone on the ship started to shout because we saw a humpback whale(座头鲸). It was wonderful. Sometimes, whales came so close to the ship that you thought you could easily touch them.

    While we were watching the whales, a guide was giving us some information about them. She told us that we saw only two kinds of whales -- 50-foot humpback whales (singing whales) and 70-foot fin back whales (the second largest whales on earth). She also said we could easily recognize a whale by its tail because every whale has a different kind of tail just like people have different fingerprints.

    They all have names, and on this trip, we saw "Salt" and "Pepper", two whales named by a biologist and a fisherman. They were swimming together all the time.

    I took twenty-seven photos, but it was very hard to take them because the whales were quick and stayed on the surface(表面) of the ocean just for a short time. It was really something. It was one of the chances that a person hardly ever experiences in life, but I had that chance.
