Question

7．Winter is often a time when we switch our activities indoors and wait for spring．We miss out on the fresh air，beautiful scenery and healthy exercise that outdoor activities in Saskatchewan offer．If you are not the skiing or snowmobiling type，ice fishing is a great way to spend part of your winter indoors．
Murry Koob，a biologist with the Saskatchewan Ministry of Environment，notes that there are over 50，000 fish-bearing waters in this province．"We have a lot of opportunities for ice fishing here，especially when most lakes are covered with ice for almost half of the year．"
It is estimated that one third of those who fish during the summer also fish in the winter．Koob says that a minimum amount of equipment is required for ice fishing．"In reality，all you need is something to cut a hole in the ice and a line with a hook on it．Warm clothes are obviously needed，too．"
Ice fishing can start as soon as the ice is thick enough to support a person walking on it：about 10cm thick．When it reaches 30cm，it will support a truck．Koob warns that ice thickness can vary greatly，so it should be tested as you crossit．He suggests that anyone fishing on the ice carry emergency equipment，such as a throw rope，in case you break through the ice．"you should always fish with a companion and let people know where you will be fishing．
Carrying a cellphone with you is also a good idea．As noted，the equipment for ice fishing an be simple and inexpensive----or it can be costly．"I've seen people fishing with a home-made chisel （鑿子） and a spool of line．But you can also spend hundreds of dollars or more on underwater cameras and portable tent-like shelters or a wooden shack．It all depends on how much you want to spend，"said Koob．
Often，the hardest part about ice fishing is getting out on the lake and cutting a hole through the ice．

Answer 1

分析 短文主要講述了冬天在冰上釣魚(yú)的做法以及應(yīng)注意的一些事情．

解答 25．B，推理判斷題，根據(jù)前一句ice thickness can vary greatly，冰的厚度會(huì)不一樣，因此當(dāng)你走過(guò)的時(shí)候要檢測(cè)一下，it指代的是ice thickness，故答案為B．
26．D，推理判斷題，根據(jù)句子He suggests that anyone fishing on the ice carry emergency equipment，such as a throw rope，in case you break through the ice．"you should always fish with a companion and let people know where you will be fishing可知，當(dāng)你冬天垂釣的時(shí)候，要帶一些拋繩預(yù)防突發(fā)事故，而且最好結(jié)伴同行或告訴別人你釣魚(yú)的地點(diǎn)，也就是要保證你的安全，故答案為D．
27．B，細(xì)節(jié)理解題，根據(jù)句子He suggests that anyone fishing on the ice carry emergency equipment，such as a throw rope，in case you break through the ice可知，拋繩的作用就是預(yù)防發(fā)生突發(fā)事故，故答案為B．
28．C，細(xì)節(jié)理解題，根據(jù)句子Ice fishing can start as soon as the ice is thick enough to support a person walking on it：about 10cm thick可知，冰的厚度達(dá)到10cm就可以在上面釣魚(yú)了，因此C選項(xiàng)表述錯(cuò)誤．

點(diǎn)評(píng) 解答任務(wù)型閱讀理解題，首先對(duì)原文材料迅速瀏覽，掌握全文的主旨大意．因?yàn)殚喿x理解題一般沒(méi)有標(biāo)題，所以，速讀全文，抓住中心主旨很有必要，在速讀的過(guò)程中，應(yīng)盡可能多地捕獲信息材料．其次，細(xì)讀題材，各個(gè)擊破．掌握全文的大意之后，細(xì)細(xì)閱讀每篇材料后的問(wèn)題，弄清每題要求后，帶著問(wèn)題，再回到原文中去尋找、捕獲有關(guān)信息．最后，要善于抓住每段的主題句，閱讀時(shí)，要有較強(qiáng)的針對(duì)性．對(duì)于捕獲到的信息，要做認(rèn)真分析，仔細(xì)推敲，理解透徹，只有這樣，針對(duì)題目要求，才能做到穩(wěn)、準(zhǔn)．
