In Tanzania,an African country,a company called APOPO trains African pouched rats(非洲有袋鼠)to find landmines(地雷)left over from the wars.The rats are trained to smell out some of the (46)E  in them.More importantly,these rats are too light to set off the landmines.
Generally speaking,after 8to 12months of training,the rats can find landmines so that they can be safely destroyed.Rats and trainers search one small area at a time.To be sure that every inch of the ground is (47)B,APOPO workers use a harness-and-rope system that guides the rats back and forth in rows.The trainer stands safely on the edge(邊緣) of the area.
When a rat smells landmines,it will dig the dirt in that spot(地點(diǎn)).The trainers (48)A each spot on a map.Later,people set off the landmines safely.
In the African country of Mozambique,nearly half of the (49)C are younger than 15years old.A lot of kids are in danger as they play and work.With the help of the rats and trainers,there will be no threat any more.

分析 文章大意:
在坦桑尼亞,一個(gè)非洲國(guó)家,一家名為APOPO的公司在訓(xùn)練非洲囊鼠尋找戰(zhàn)爭(zhēng)留下的地雷.
小鼠被訓(xùn)練,可以特異性的聞到地雷里面存在的特殊的化合物,因此可以通過(guò)小鼠的反應(yīng)來(lái)推測(cè)有沒(méi)有地雷.
這有兩點(diǎn)好處,一方面可以訓(xùn)練小鼠快速準(zhǔn)確的預(yù)知地雷的位置,另一方面可以避免使用人力,減小傷亡.

解答 46.E,考察名詞辨析及上下文理解,句子的意思為"這些老鼠被訓(xùn)練成聞出地雷中的…味",而且在定冠詞the后面肯定跟一個(gè)名詞.根據(jù)所提供的兩個(gè)名詞,本題答案為chemicals(化學(xué)藥品).因此選擇E.
47.B,考察動(dòng)詞辨析及上寫(xiě)文理解,句子的意思為"確保每一寸土地…",可能填"形容詞"或"被動(dòng)語(yǔ)態(tài)",根據(jù)前句意思"老鼠和工作人員搜尋更小的區(qū)域",所以本題答案為checkecd(被檢查).因此選擇B.
48.A,考察名詞辨析及上下文理解,句子的意思為"當(dāng)老鼠聞出地雷后,挖出.然后工作人員對(duì)于這個(gè)地點(diǎn)在地圖上進(jìn)行…",根據(jù)意思應(yīng)該填一個(gè)動(dòng)詞,根據(jù)前句和后句的時(shí)態(tài),應(yīng)為"一般現(xiàn)在時(shí)",所以本題答案為mark(標(biāo)記).因此填寫(xiě)A.
49.C,考察名詞辨析及上下文理解,句子的意思為"將近一般的…都小于15歲",根據(jù)意思肯定填一個(gè)名詞,那么就是"一般的人(口)",所以本題答案為population(人口).因此選擇C.

點(diǎn)評(píng) 本題題型為選詞填空.在選擇給定詞語(yǔ)時(shí),再考慮文章大意的前提下,還應(yīng)該注意文章及句子所用的時(shí)態(tài),以及所填寫(xiě)的詞在句子中的位置.通過(guò)這些判斷,適當(dāng)改變?cè)~匯形式,以符合題目要求.

Square Dancing
Square dancing is becoming more and more popular with the elder people in China.Not only is it a good way of keeping fit,but also it's a good time for the elder to walk outdoor to make and meet friends.No wonder that most dancers say that dancing makes them look younger and feel more confident.However,when people in large number dance to loud music,they create the noise that neighborhoods find it painful to bear.What's worse,some dancers even fight for a certain place to dance and lead to blooding.
In my opinion,we shouldn't dance too late or dance to too loud music to disturb others'life.Let's dance politely and happily..
