C. It is open in the afternoon. D. It has the most skilled teachers.
My namo is Eivind Trodden, I'm 42 yoars old and on Svalbard in the North Pole, My background was originally（起初）software engineoring，and yoars later I decided to go ahcad and get my pilot license. This year I tried my hands at technology and got a job at Svatsat, tho northernmost Satellite（卫星） Ground Station in the world. Now I work as a pilot and an operations engineer,
Originally, I moved here for the job. This was thefirst pilot job I got. Aftor a whilo, I was attracted by the place, and right now the most important thing for me is to live here.
It is wonderful and full of differences. The polar night is balancad with the midnight sun.Here the year is much like a day. The winter is night. In the morning there is ice, snow and then spring. Then there is the endless day of summer, and finally, the town sottlos in with the sunset of autumn.
The summer is the most difficult. It is harder to create darknoss than light. You have to have good blinds on your bedroom windows. A good trick is to create your own ovoning. I liko to close the blinds and sit down in relative darkness with a good book or a movie bofore I go to bed.
The dark season is the favorite of many people living here. There are fewer tourists, and people have a chance to get together and be social after the busy summer. You have to be self-controlled though, and not start lighting candles in the middle of the day. Don't underestimate（低估） the cost of living here. You need a large number of tools to experienco Svalbard to the fullest.

5、梅州市高三总复习质检试卷(2026.3) 答案
25、如图所示电路，R1＝7 Ω，R2＝3 Ω，当S闭合时，电压表的示数为21 V，当S断开时，电压表的示数为14 V。求R3的阻值。
【答案】R3的阻值为5Ω。
【详解】试题分析：根据串联电路特点：电流相等I=I1=I2；U=U1+U2，结合欧姆定律I=及其变形公式U=IR和R=分析求解。
解：当S闭合时，R1R2串联，U1=21V R1=7Ω R2=3Ω，电流相等
所以I2=I1===3A；
U2=I2R2=3A×3Ω=9V，
因此U=U1+U2=21V+9V=30V；
