1. has been selected 考查动词的时态和语态。该句的主语the spt是第三人称单数，与谓语动词select之间是一种被动关系，再根据时间状语“S far”可知，此处用现在完成时的被动语态，故填has been selected。
2. where 考查定语从句。先行词为“China's Sichuan Prvince”，关系词在定语从句中作地点状语，故填where。
3. has 考查主谓一致。本句的主语“reserve”是第三人称单数，且此处是陈述客观事实，所以用一般现在时的第三人称单数形式。故填has。
4. resurces 考查名词的单复数。resurce是可数名词，此处用复数形式。故填resurces。
5. briefly 考查副词。分析句子结构可知，空处修饰动词“intrduced”，应用副词形式。故填briefly。
6. a 考查冠词。表示“一个”用不定冠词，名词giant以辅音音素开头，故填a。
7. releasing 考查非谓语动词。“refer t sth.”中“t”为介词，其后用v.­ing形式作宾语。故填releasing。

6. pllutin 考查词性转换。has decreased后跟名词作宾语，故填pllutin。

Ⅰ. 阅读理解
Wildlife fficials in Utah have been stcking their remte muntain lakes by drpping fish frm airplanes since 1956. And n Aug. 21, the Utah Divisin f Wildlife Resurces (DWR) shared a vide f them ding just that. In the vide, the small fish erupted frm the bttm f an airplane int the water.
It might seem like the fall frm the plane wuld result in a fatal (致命的) end fr the fish, but the Utah DWR explained that at least 95 percent f the fish are expected t survive. “That's because the yung fish are s small — nly 1 t 3 inches (2.5 t 7.6 centimetres) lng — that they fall t the water like leaves，” said Phil Tuttle the utreach manager fr the suthern regin ffice f the Utah DWR.
“The pilt lies just abve the tree line t drp the fish, r as lw as pssible while cnsidering ther natural barriers like cliffs and muntains，” Tuttle tld Live Science in an email. Years f netting surveys (cllecting fish in a net and cunting them) and decades f recreatinal fishing suggest the fish d all right after the drp. Utah DWR staff members have als cnducted netting surveys within minutes f a drp t check survival rates.
Mre than 200 f Utah's remte muntain lakes are stcked every year using this aerial (航空) fish­drp methd. The lakes are ften far frm any rad and can take a lng time t reach by land, which makes land transprts mre stressful fr the fish cmpared with aerial transprts.
Mst f the stcked lakes wuld be fishless, were it nt fr the DWR's stcking effrts. The DWR primarily stcks lakes with sterile fish s they can cntrl the ppulatin and minimise (减至最小) their impact n native wildlife species. The mst cmmn species t make these lights are varius species f trut (鲑鱼)．
1. What is the pssible reasn fr the high survival rate f the fish?
A. Their thick skin.
B. Their small size.
C. Their strng bdy.
D. Their gd appetite.
2. Hw can Utah DWR get t knw the survival rates f the fish?
A. By ding netting surveys.
B. By cunting natural barriers.
C. By recrding the drp height.
D. By hlding fishing.
3. Why d Wildlife fficials in Utah drp fish frm airplanes?
A. It's the cheapest way available.
B. The lakes are unreachable by land.
C. It's better fr the fish than land transprts.
D. They want t train the fish in a special way.
4. What des the underlined wrd “sterile” in the last paragraph prbably mean?
A. Fierce and aggressive.
B. Unable t prduce babies.
C. Cmpletely free frm bacteria.

【语篇解读】本文是一篇新闻报道。文章介绍了犹他州的野生动物官员自1956年起就通过从飞机上放鱼来为偏远的山区湖泊放养鱼类，犹他州野生动物资源局分享了他们这样做的视频。
1. B 细节理解题。根据第二段中的“That's because the yung fish are s small — nly 1 t 3 inches (2.5 t 7.6 centimetres) lng — that they fall t the water like leaves”可知，是因为它们体型小。故选B。
2. A 细节理解题。根据第三段中的“Years f netting surveys(cllecting fish in a net and cunting them) and decades f recreatinal fishing suggest the fish d all right after the drp. Utah DWR staff members have als cnducted netting surveys within minutes f a drp t check survival rates.”可知选A。
3. C 推理判断题。根据倒数第二段内容可知，对鱼来说空中运输比陆地运输好。故选C。
4. B 词义猜测题。根据最后一段中的“The DWR primarily stcks lakes with sterile fish s they can cntrl the ppulatin and minimise (减至最小)their impact n native wildlife species.”可知，画线部分单词是“不育”的含义。故选B。
