By contrast, the majority of their male counterparts visit only one country and tend to travel

32、in groups, says a survey by the Gap Year company, which provides information and services for students considering taking a year out. More women than men say that their prime reason for taking time off is to see the world and experience different cultures. Men were more likely to rank“having fun”

33、 higher on their list of preferences. Women were more likely to value the challenge of a foreign trip, and many cited reasons such as learning a language and meeting new people. The more adventurous gap years taken by women seem to work to their benefit; more than three quarters of those surveye

34、d reported increased confidence, self-reliance and independence, whereas only half of the men had that experience. The research also showed that women were more likely to do voluntary work while travelling, with more than one in ten helping with teaching or development projects. One of the reason

35、s given for this is a wish to see the country in an authentic light. A greater proportion(比例)of women than men faced objections or criticism from their families over their gap-year plans. Among the men surveyed, lack of money was the main barrier to travel. Carolyn Martin, a doctor from London,

53、題。根據(jù)三個(gè)回帖子時(shí)間的比較可知答案。 3.【解析】選B。推理判斷題。根據(jù)第二個(gè)回帖的第三句That’s when my daughter Madeline tried to persuade me to try her special Royal Jelly．和第三個(gè)回帖的第一句When my mom Madeline was introduced to Royal Jelly, it affected my life, too! 可知答案。 4．【解析】選B。推理判斷題。從文章的結(jié)構(gòu)“發(fā)帖、跟帖”可知。 5.【解析】選D。詞義猜測題。文章第二段提到students，所以相比之下，D項(xiàng)

54、最適合。在英國等國家，年輕人會有“空檔年”，即上完高中、上大學(xué)之前的這段時(shí)間。而C項(xiàng)是最大的干擾項(xiàng)，由常識可知，大學(xué)畢業(yè)后，學(xué)生一般都得忙著找工作，然后上班，沒有足夠的時(shí)間去旅行，所以D項(xiàng)比C項(xiàng)更貼切。 6．【解析】選C。細(xì)節(jié)理解題。在文章前兩段中，作者提到“三分之一的女性在空檔年會獨(dú)自旅行”，而男性更傾向于團(tuán)體旅行。A項(xiàng)應(yīng)該是gap years，而不是the summer holidays，B項(xiàng)表示泛指，本文是特指在空檔年出游，故B項(xiàng)中的in a year是不正確的。D項(xiàng)women改為men則正確。 7．【解析】選B。細(xì)節(jié)理解題。由第六段第一句A greater proportion o

55、f women than men faced objections or criticism from their families over their gap-year plans. 可知，女性更喜歡在空檔年出游，但與男性相比，她們面臨更多的反對意見。 8．【解析】選A。主旨大意題。文章第三段提到女性旅行原因是了解世界、體驗(yàn)不同的文化、學(xué)習(xí)語言、認(rèn)識新朋友。在第四段中作者提到“more than three quarters of those surveyed reported increased confidence, self-reliance and independence(超過

56、四分之三的女性通過旅行會增強(qiáng)自信、自立和獨(dú)立)”，而只有一半的男性有同樣的體驗(yàn)。所以A項(xiàng)正確。D項(xiàng)是最大的干擾項(xiàng)，其實(shí)D項(xiàng)與原文第一段首句相比缺少了關(guān)鍵的狀語限定部分(when travelling abroad in gap years)。當(dāng)堂探究 1. If you open up any medicine cupboard or go to medicine counter in the world, it is likely that you will find aspirin and penicillin. open up 打開（門、容器等）；營業(yè)，開業(yè)；開辟，開創(chuàng)，開

57、拓 The doorman __opens up_________（打開） the school gate at six every morning. In this way they _opened up__________ a favourable situation. It’s likely that… sb./sth. is likely to do sth. [翻譯] 這趟火車很可能晚點(diǎn)。 It is likely that the train will be late. 比較：probable: ad

58、j. 很可能的，與likely意思相近，有時(shí)可以互換；possible的語氣稍弱。他們各自的句型如下：It’s probable/possible for sb. to do sth. It’s probable/possible that … It’s likely that… sb./sth. is likely to do sth. 2. Nearly 3,500 years ago, people chewed on leaves or drank a kind of tea made from leaves possessing a special chemical t
