研究表明,地球磁场对鸽子识别方向起着重要作用.鸽子体内的电阻大约为103Ω,当它在地球磁场中展翅飞行时,会切割磁感线,在两翅之间产生动生电动势.这样,鸽子体内灵敏的感受器即可根据动生电动势的大小来判别其飞行方向.若某处地磁场磁感应强度的竖直分量约为0.5×10-4T.鸽子以20m/s速度水平滑翔,则可估算出两翅之间产生的动生电动势约为( )

    After travelling many times with my family members, I went alone to Italy for a long weekend. I traveled by a train and checked into my hotel before exploring the beautiful town. I went out for dinner alone, that meant I could watch people and took in the atmosphere. The next day I went to Lake Garda and took some lovely picture. I then read a book and sat under the sun for a few hours! I had a really amazed time. I think the best thing about traveling alone is you can be selfish and do exactly what you want to. You are in control of your day and fun, but my advice is to take the opportunity to travelling alone. As long as you stay safely, you will have a wonderful time!

    My high school life has made me learn many things. Between them teamwork is the most significantly for me. In fact, I didn't realize its importance after I was elected monitor. In the begin, I did almost all the duties myself, however, others students cared little about class activities. Therefore, I worn out and depressed. Then I turned to my head teacher but he advised me to cooperate with others. Gradually, I realized the strengths of my classmates and managed to have everyone to play a part in class. It is working in teams instead of on my own which has freed me of trouble and make my work more efficient.

    Yesterday my friend Julia and me had lunch in the Pizza Hut behind our school. I knew Julia wasn't crazy about pizzas, but she came along just because me. At the table next to ours, there were two guys from our class. One of them was real funny. He tried to imitate all the customer in the Pizza Hut. We couldn't stop to laughing. And there were some people whom did not like the fact that two boys were imitating them. They complained to an owner of the Pizza Hut, so he came over and tell them to stop. Seeing it, Julia and I was greatly embarrassed.

    One Monday afternoon, we were playing the basketball on the playground while I suddenly slipped and fell over. On seeing that, all my classmates rushed to me. Under the help of several other students, Li Xiang, one of my best friend put me on his back and head for the clinic immediately. It turned out that my right ankle got injured but I had to be sent to hospital. He did not leave until an ambulance was arrived. The following day, he came to see me. To my greatly relief, he brought textbooks to them and helped me with my lessons. It was a great pleasure have such a devoting friend.
