　　Wildlife protection

　　Back from the dead: One third of “extinct”

　　animals turn up again

　　Conservationists are overestimating the number of species that have been driven to extinction, scientists have said.

　　A study has found that a third of all mammal(哺乳動物)species declared extinct in the past few centuries have turned up alive and well.

　　Some of the more reclusive(隱居的)creatures managed to hide from sight for 80 years only to reappear within four years of being officially named extinct in the wild.

　　The shy okapi—which resembles a cross between a zebra and a giraffe—was first discovered in the Democratic Republic of Congo in 1901.

　　After increasingly rarer sightings, it vanished from the wildlife radar for decades from 1959, prompting fears that it had died out.

　　But five years ago researchers working for the WWF found okapi tracks in the wild.

　?、赥he pills gave him some relief for the moment.(減輕)

　?、跿he flood-stricken area is in desperate need of food and medicine relief.(救濟物品)

　　[歸納拓展]

　　(1)in relief 如釋重負；松了口氣

　　(2)(much)to one's relief 使某放心(寬慰)的是

　　(3)feel a sense of relief 如釋重負

　　[運用提升]

　　(2011·濰坊一模)It came as a great________to the parents that their son finally came back safe and sound.

　　A. favor

　　B. sense

　　C. relief

　　D. relaxation

　　答案：C　考查名詞辨析。句意：兒子最終安然無恙地回來是這對父母最大的寬慰。favor“幫助”；sense“感覺；見識”；relief“寬慰”；relaxation“放松”。

　　2．contain vt. 包含；容納；克制(強烈的感情等)；抑制

　　Some western countries are trying to contain the development of China.

　　有些西方國家在試圖遏制中國的發展。

　　[歸納拓展]

　　contain oneself 克制自己

　　container n. 容器；集裝箱；貨柜

　　辨析：contain, include

　　(1)contain意為“包含，含有，容納，里面裝有”，指包含全部內容或數量；也可指里面所包含的成分；不用于進行時態；表示“容納”時，相當于hold。

　　(2)include意為“包含；連……在內；計入；算入；包括”，用于表示所包含事物中的一部分，其后的賓語往往是主語的一部分。including為介詞，放在所包括的事物之前；included為形容詞，放在被修飾的名詞之后。

　　①A sunken ship containing a lot of chinaware was discovered under water in the South China Sea.

　　在中國南海發現了一個裝有大量瓷器的沉船。

　?、赥here were four passengers on the bus, including the old lady/the old lady included.

　　B．effect; affect

　　C．effect; an effect

　　答案：C　考查affect及effect的用法。句意：這項新的法律已經生效了。它肯定會對這個國家的工業有影響。come into effect“開始實施，開始生效”；have an effect on“對……有影響”。

　　His talents are greatly appreciated by the boss.(欣賞)

　　I would appreciate hearing from you.(感激)

　　We didn't appreciate that he was badly ill.(意識到)

　　Property values appreciated yearly.(增值)

　　[歸納拓展]

　　(1)appreciate＋n./pron./v.-ing 重視；感激

　　I would appreciate it if... 假如……我將不勝感激

　　(2)appreciation n. 欣賞；感激

　　點撥：(1)appreciate后不能用不定式，而要用動名詞作賓語；其后接“事”作賓語而不能接“人”(與thank相反)。

　　(2)appreciate 之后不能直接跟if引導的賓語從句，若接if從句時，要借助于it。類似用法：like, hate, dislike, enjoy等動詞之后的if，when從句。

　?、買 would appreciate_it_if you could turn the radio down.

　　如果你能將收音機音量調小些，我會不勝感激。

　　I don't like_it_when my four children follow me every- where.
