    The Kirtland’s warbler(莺)has required protections since the foundation of Endangered Species Act (ESA), but that’s about to change. The Fish and Wildlife ServiceFWStoday announced it is removing the songbird from the endangered species list

“The effort to recover the Kirtland's warbler is a successful example of how to save endangered species,” said Margaret Everson, director of FWS. “The Kirtland's warbler has responded well to active management over the half century.” In 1971, the Kirtland’s warbler population declined to approximately 201 singing males and was restricted to six counties. By 2015, the population reached 2,383 singing males and had spread geographically. FWS noted the frequent and persistent singing of male warblers during the breeding season made counting possible.

“The primary threats identified at listing and during development of the recovery plan have been managed,” said FWS. Modern wildfire suppression(扑灭)practices greatly altered the natural disturbance system, which enabled the growth of the jack pine forests favored by the species, FWS noted. Michigan state has replanted approximately 90,000 acres of Kirtland's warbler habitat over the past 30 years. Timber (木材)incomes offset the cost of replanting jack pine needed to support a survivable bird population.

But while the bird is falling off the ESA list, officials note that it remains a “conservation-dependent species." Conservation of the Kirtland's warbler will continue to require a harmonious approach for carrying out future conservation work, like partnerships and sufficient funding, FWS stated. Under the Endangered Species Preservation Act of 1966, the Kirtland's warbler was federally listed as an endangered species in 1967.

“This remarkable bird has a most impressive, exemplary success story that illustrates effective conservation and cooperation at work,” added Heather Good, executive director of Michigan Audubon. Shawn Graff, vice president of American Bird Conservancy's Great Lakes program, pointed out the delisting (除名)is “cause for celebration and proof that the Endangered Species Act works.”

1.The passage is probably taken from_____.

A.a science fiction B.a news report

C.a biography D.a novel

2.What does the underlined word “offset” in paragraph 3 mean?

A.Make up for. B.Add to.

C.Fix. D.Estimate.

3.Which of the following is NOT the reason for the recovery of Kirtland’s warbler?

A.Ample funding. B.Cooperative work.

C.The foundation of FWS. D.The control of wildfire.

4.What can be concluded from the passage?

A.The male Kirtland's warblers seldom sing in the breeding season.

B.Heather Good was not very satisfied with the conservation work.

C.The Kirtland's warbler was listed as an endangered species only in one state.

D.Margaret Everson thought highly of the conservation of the Kirtland's warbler.

 

1.B 2.A 3.C 4.D 【解析】 这是一篇说明文。本文介绍美国密歇根州的科特兰野莺,从濒危物种名单被移除的新闻。讲述了其堪称野生动物保护工作模板的保育经验:通过各方合作,灵活重建栖息地,人们可以以较低的成本挽救一个濒危的野生物种。 1.推理判断题。全文直接引用相关专家的观点如:“The effort to recover the Kirtland's warbler is a successful example of how to save endangered species,” said Margaret Everson, director of FWS. “The Kirtland's warbler has responded well to active management over the half century.”和“This remarkable bird has a most impressive, exemplary success story that illustrates effective conservation and cooperation at work,” added Heather Good, executive director of Michigan Audubon等。信息的价值/重要性从前往后呈倒金字塔型,语言风格简明直白,没有主观情绪——由这几处细节可以明显判定,本文是一则新闻。故选B项。 2.词义猜测题。由划线词所在句的前句Michigan State has replanted approximately 90 , 000 acres of Kirtland's warbler habitat over the past 30 years.可知,密欧根州重新种了很多叶松,作为野莺栖息地。根据常识判断,该州这一做法是要花钱的。由画线词所在句 Timber incomes offset the cost of replanting jack pine可知,重新种树的花销被木材收入给offset 了,根据常识及逻辑可判断,此处offset意为“抵消”。故选A项。 3.细节理解题。第四段中 Conservation of the Kirtland's warbler will continue to require a harmonious approach for carrying out future conservation work, like partnerships and sufficient funding(保护科特兰野莺将继续需要一个和谐的方式来开展未来的保护工作,比如合作关系和充足的资金)可知,对这些野莺的保护仍然需要合作以及充足的资金,故A、B项相关;再由第三段中Modern wildfire suppression practices greatly altered the natural disturbance system, which enabled the growth of the jack pine forests favored by the species(现代扑灭野火的措施极大地改变了自然干扰系统,使得受科特兰野莺青睐的针叶松林得以生长)可知,扑灭野火也相关,故D 项也相关。根据排除法,故选C 项。 4.推理判断题。由第二段中The effort to recover the Kirtland's warbler is a successful example of how to save endangered species(恢复科特兰野莺的努力是拯救濒危物种的成功范例)可知,Everson对该保育案例是赞赏的。故选D项。

    When you start working on something but don't finish it, thoughts of the unfinished work continue to jump into your mind even when you've moved on to other things. Psychologists refer the phenomenon as the Zeigamik effect. The effect was first observed by a Russian psychologist named Bluma Zeigamik. While sitting in a busy restaurant in Vienna, she noted the waiters had better memories of unpaid orders. Once the bill was paid, however, the waiters had difficulty remembering the exact details of the orders.

In one of her studies, participants were asked to complete simple tasks such as putting together puzzles, or solving math problems. Half of the participants were interrupted halfway through these tasks. After an hour-long delay, Zeigamik asked the participants to give an account of what they'd been working on. She discovered that those who had their work interrupted were twice as likely to remember what they had been doing as those who had actually completed the tasks.

We can use this effect to our advantage. For example, if you're struggling to memorize something important, momentary interruptions might actually work to your advantage. Rather than simply remember the information over and over again, review it several times and then take a break. While you're focusing on other things, you'll find yourself mentally returning to the information you were studying.

We often put off tasks until the last moment, only completing them in a rush at the last possible moment. Unfortunately, this tendency can lead to heavy stress and even poor performance. One way to overcome this is to put the Zeigamik effect to work. Start by taking the first step, no matter how small. Once you have begun — but not finished — your work, you'll find yourself thinking of the task until, at last, you finish it. You might not finish it all at once, but each small step you take puts you closer to your final goal.

1.What does the Zeigamik effect refer to?

A.Waiters tend to have good memories.

B.Once interrupted, one will forget things easily.

C.Most people can't focus on one thing for a long time.

D.People remember unfinished tasks better than completed ones.

2.How should we study according to the Zeigamik effect?

A.Repeat over and over again.

B.Divide our study session.

C.Focus on several tasks at a time.

D.Have enough rest before studying.

3.What’s the main idea of the last paragraph?

A.How to get rid of heavy stress.

B.Why we should set a final goal.

C.How to break the habit of delaying work.

D.Why we always complete tasks in a rush.

    Downey's mother spent one year studying abroad through an international exchange program with a French school. She often talked about how exciting and interesting the experience was. So, even before finishing high school, Downey had decided to follow suit one day.

Downey began studying architecture at Lehigh University in Bethlehem, Pennsylvania in 2004. Near the end of her second year, she started to feel unhappy with her school and decided it was time to study abroad.

U. S. colleges and universities commonly have joint programs with foreign schools that permit student exchanges. These programs usually last half a school year or sometimes a whole school year. The classes students take abroad usually give them credits toward their degree. In a four­year degree program, the third year is the most common time for American college students to study abroad. Many students think they need a change before what is usually their final and most difficult year of study.

Downey said her school did not want her to go at first. The architecture program at Lehigh was very intense, and her professors were worried she might miss learning important material. However, she was eventually able to get special permission to study internationally for a whole year. During the fall term in 2006, she attended a Danish international school in Copenhagen, Denmark, explaining she did so because Danish architects are well known for their housing design.

Young adult as she was, she had to deal with travel documents and many other issues (问题) on her own. Overcoming the language barrier is the biggest challenge of studying abroad. However, she had a lot of emotional (情感的) and financial support from her family. She learned life lessons and made friendships and memories that have lasted to this day. She said, “The more you're out of your comfort zone, the more rewarding the experience is in the end.”

1.What does Downey's mother mean to Downey?

A.A friend. B.A dreamer.

C.An example. D.An expert.

2.What made Downey choose the Danish international school?

A.The famous learned professors.

B.The casual learning environment.

C.The impressive academic reputation.

D.The favorable geographical location.

3.What can we infer according to the last paragraph?

A.It was not easy for Downey to study abroad.

B.The comfortable life is likely to ruin the future life.

C.Downey was too young to take care of herself.

D.Downey's parents could hardly afford her education.
