小题1:三角形ABC全部为黑夜,那么南极圈及其以南为极昼现象,为冬至日。地球上白昼与黑夜的范围始终各占一半。

小题2:由题意可知AC为昏线,BC线平分夜半球,若为日界线,则180°经线地方时为0时。北京时间为20时,伦敦时间为12时。北极科考应在北半球夏季。舟山渔场此时为冬季,应为带鱼汛。

     Have you ever thought about keeping a pet goldfish? First you need to know how to keep it.     

     Get a fishbowl      

     First get a fishbowl. Make sure the fishbowl is large enough for the goldfish to swim in. You should

 keep the fishbowl clean. Don' t clean the fishbowl with soap. Hot water will clean it well.     

     Feed a goldfish       

     Goldfish eats almost any food. And you can also buy some special food for your goldfish in shops. Do

 not feed it too much food. Feed it as much as it can eat in three minutes one time.      

     Keep the water clean     

     Dirty water is not good for the health of the goldfish. If the water is dirty, the goldfish will easily 'get 

 sick and may die. Change 25% of the water at least once a week. Never change all of the water because 

 it includes something that your goldfish needs.      

     As you can see, keeping goldfish as pets is  not difficult.
