题型:阅读理解

问题:

It’s great fun to explore new places—it feels like an adventure, even when you know you’re not the first to have been there. But make sure not to get lost or waste time going round in circles.

·Do the map reading if you’re being driven somewhere. It’ll be easier if you keep turning the map so it follows the direction you’re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you’ll have to move to the back seat.

·Get a group of friends together and go exploring. You’ll need a good map, a compass(指南针), a raincoat, a cellphone to call for help in case you get lost, and a bit of spare cash for emergencies. Tell someone where you’re going before you set out and let them know what time you expect to be back. The test is not in getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

See if your school or a club organizes orienteering(越野识途比赛) activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C, etc) in the fastest time, or simply as a spare-time activity. Either way, it’s not only good fun, but a great way to keep fit.

A.make people work fast

B.help people stay healthy

C.help people organize other activities

D.make people get prepared for sports.小题4: The text mainly talks about _____.

如图甲是某金属材料制成的电阻R随摄氏温度t变化的图象,图中R0表示该电阻在0℃时的电阻值,已知图线的斜率为k.若用该电阻与电池(电动势为E、内阻为r)、理想电流表A、滑动变阻器R′串联起来,连接成如图乙所示的电路.用该电阻做测温探头,把电流表A的电流刻度改为相应的温度刻度,就得到了一个简单的“金属电阻温度计”. 

(1)根据图甲,温度为t(t>0℃)时电阻R的大小为______.

(2)在标识“金属电阻温度计”的温度刻度时,需要弄清所测温度和电流的对应关系.请用E、R0、R′(滑动变阻器接入电路的阻值)、k等物理量表示待测温度t与电流I的关系式t=______.

(3)如果某次测量时,指针正好指在在温度刻度的10℃到20℃的正中央,则测量值______15℃(填“大于”、“小于”或“等于”).
