Question

  Have you ever thought, "I wish I could take a year off and just travel around the world?" Well,three lucky American teenagers were able to do just that. The teenagers―two males and one female―got an all-expenses-paid hike to five continents.

  This trip didn't include any fivestar hotels or shopping fun. 18-year-old Jamie Fiel from Keller,Texas,17-year-old Arsen Ewing from Canyon,California,and 16-year-old Tyler Robinson from Lincoln,Massachusetts,didn't expect fancy treatment. They signed up for the experience of a lifetime,which included hard work and often uncomfortable accommodations,and they may encounter with some of nature's most dangerous animals and environments.

  Jamie,Arsen,and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored (贊助) this adventure. Each year,Earthwatch Institute employs thousands of volunteers worldwide to help with scientific research projects.

  The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their loca?tions,and included measuring and attending pink flamingos in Kenya's Great Rift Valley,and tracking giant sea turtles in Costa Rica.

  As they worked with the scientists of Earthwatch Institute,Jamie,Arsen,and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teenagers went from country to country and witnessed different environmental dangers and challenges,they understood that so?lutions to important environmental issues start with the power of one person's ac?tions. They realized that each of them can make a difference.

Answer 1

[文章大意]三個(gè)學(xué)生在Earthwatch Institute的贊助下，幸運(yùn)地參加了一次環(huán)球環(huán)境考察之旅，最后他們意識(shí)到地球環(huán)境問題的解決需要每個(gè)人的參與。

1. A細(xì)節(jié)理解題。根據(jù)第四段第一句"The group went all around the world to get a close look at the most pressing envi?ronmental issues of our time."可知，這次旅行是為了近距離地感受我們現(xiàn)在所面臨的那些迫切需要解決的環(huán)境問題，故答案為A.

2. C細(xì)節(jié)理解題。根據(jù)短文第二段可知，這次旅行充滿了困難甚至危險(xiǎn)，所以他們要付出很大的努力才能完成任務(wù)，包括獲取環(huán)境信息等。

3. D推理判斷題，根據(jù)第三段最后一句及Earthwatch Insti?tute所贊助的這次活動(dòng)可推知，Earthwatch Institute是一個(gè)向關(guān)心地球環(huán)境的人們普及環(huán)境科學(xué)知識(shí)的組織。
