Question

18．If you want to be a citizen scientist，the National Science Foundation（NSF） has got you covered．NSF supports citizen scientists across all areas of science，whether your passion（熱情）is scanning the night sky，exploring your own backyard or playing video games．
Join a Flock of Birders
eBird is an online platform that allows bird-watchers to record their sightings on a massive online database．With more than 100，000 active users，eBird involves bird population，distribution（分布）and habitat that users can explore in real time．In May 2015，there were 9.5 million records uploaded．
Count Every Drop
The Community Collaborative Rain and Snow Network is the largest provider of daily rainfall observations in the United States．Volunteers set up rain instruments and record data every time a rain，or snow storm passes．Data is organized and shared on the CoCoRaHS website，and used by the National Weather Service，scientists，farmers and so on．
Join the Plankton Party
Without plankton（浮游生物），life in the ocean would not exist．These tiny things form the base of the food chain and play an important role in the global carbon cycle．Plankton Party encourages citizen scientists to identify images snapped（拍照）by the ISIIS，an underwater robot．Classifying the images helps researchers understand plankton diversity，habitat and behavior．

21．What can bird-watchers do with eBird？C
A．Watch birds through satellites．
B．Choose their favorite birds．
C．Upload their sightings to a database．
D．Observe the night sky
22．Which subject can you learn about if you join Count Every Drop？D

Answer 1

分析 你想成為一名公民科學(xué)家，NSF支持所有科學(xué)領(lǐng)域的公民科學(xué)家，本文介紹了集中成為公民科學(xué)家的國家科學(xué)基金會(huì)．

解答 21．C  細(xì)節(jié)理解題．根據(jù)句子；eBird is an online platform that allows bird-watchers to record their sightings on a massive online database．eBird是一個(gè)在線的平臺(tái)使觀鳥者記錄他們的觀測(cè)在一個(gè)巨大的在線數(shù)據(jù)庫．所以C選項(xiàng)上傳他們的目擊到數(shù)據(jù)庫是正確的．
22．D 細(xì)節(jié)理解題．根據(jù)句子：Volunteers set up rain instruments and record data every time a rain，or snow storm passes．Data is organized and shared on the CoCoRaHS website，and used by the National Weather Service，scientists，farmers and so on．志愿者建立雨儀器記錄數(shù)據(jù)，每一次雨或暴風(fēng)雪過去．?dāng)?shù)據(jù)是有組織的、可共享的CoCoRaHS網(wǎng)站，并被國家氣象服務(wù)站，科學(xué)家、農(nóng)民等應(yīng)用．可見這家可讓人學(xué)到更過的天氣的知識(shí)，所以答案選D．
23．A 細(xì)節(jié)理解題．根據(jù)句子：Plankton Party encourages citizen scientists to identify images snapped（拍照）by the ISIIS，an underwater robot．Classifying the images helps researchers understand plankton diversity，habitat and behavior．可見Plankton Party可幫助研究人員了解浮游生物，所以答案選A．

點(diǎn)評(píng) 本文考查細(xì)節(jié)題為主，細(xì)節(jié)題可以在文章中直接找到與答案有關(guān)的信息？或是其變體．搜查信息在閱讀中非常重要它包括理解作者在敘述某事時(shí)使用的具體事實(shí)、數(shù)據(jù)、圖表等細(xì)節(jié)信息．在一篇短文里大部分篇幅都屬于這類圍繞主體展開的細(xì)節(jié)．做這類題一般采用尋讀法？即先讀題，然后帶著問題快速閱讀短文，找出與問題有關(guān)的詞語或句子，再對(duì)相關(guān)部分進(jìn)行分析對(duì)比，找出答案．
