2、Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world. But ecologists can\'t be everywhere so they\'re turning to non-scientists, sometimes called citizen scientists, fｏｒhelp. Climate scientists are not present everywhere. Because there are so many places in the world ａｎｄ　not enough scientists to observe all of them, they\'re asking fｏｒyour help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. ａｎｄ　send their observations to a giant ｄａｔａｂａｓｅ to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready fｏｒthe conditions where they live. All that\'s needed to become one is a few minutes each day ｏｒeach week to gather data ａｎｄ　send it in. Aｇｒｏｕｐof scientists ａｎｄ　educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group\'s first efforts relies on scientists ａｎｄ　non-scientists alike to collect data about plant flowering ａｎｄ　leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website. "People don\'t have to be plant experts, they just have to look around ａｎｄ　see what\'s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we\'ll be able to make an estimate of how plants ａｎｄ　communities of plants ａｎｄ　animals will respond as the climate changes. "What is the final purpose of Project BudBurst?【单选题】

A.To study when plants will have their first buds.

B.To find out the types ofplants in the neighborhood.

C.To collect life cycle data on a variety of common plants from across the United States.

D.To investigate how plants ａｎｄ　animals will respond as the climate changes.

正确答案:D

答案解析:问题为final purpose，所以选D，跳过C。

3、Meet Your MemoryMemory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. There are a number of different ways in which a person may have a "good" memory.Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the blain until it is needed; ａｎｄ　(3) retrieval (提取) refers to getting the material back out when it is needed.Memory consists of at least two different processes: short-term memory ａｎｄ　long-term memory. Short-term memory has a limited capacity ａｎｄ　a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), ｏｒgrouping separate bits of information into larger chunks. Long-term memory has an almost unlimited capacity.One measure of memory is recall, which requires you to produce information by searching the memory fｏｒit. In aided recall, you are given cues (提示) to help you produce the information. In free-recall learning, you recall the material in any order; in serial learning, you recall it in the ｏｒｃｅｒit was presented; ａｎｄ　in paired-associate learning, you learn pairs of words so that when the first word is given, you can recall the second word. A second measure of memory is recognition in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time ａｎｄ　how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Paragraph 3 ______.【单选题】

A.Why do we forget things?

B.How do we measure memory?

C.What are the stages memory consists of?

D.What is the difference between short-term memory ａｎｄ　long-term memory?

E.What is memory?

F.Who may have a poｏｒmemory?

正确答案:D

答案解析:第三段没有主题句，主要讲述了两种不同的记忆过程，即短期记忆和长期记忆，并分别从记忆储存量和时间两方面进行对比。D选项What is the difference between short-term memory ａｎｄ　long-term memory?（短期记忆和长期记忆有什么不同？）与其意思一致，故D为正确答案。

4、Cloning: Future Perfect?1 A clone is an exact copy of a plant ｏｒanimal produced from any one cell. Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997, research into cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to create two identical calves using cloning technology. A mouse has also been cloned successfully. But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement: "We will have managed to clone a human being within the next two years," he told the world. 2 Seed\'s announcement provoked a lot of media attention, most of it negative. In Europe, nineteen nations have already signed an agreement banning human cloning ａｎｄ　in the US the President announced: "We will be introducing a law to ban human cloning ａｎｄ　many states in the US will have passed anti-cloning laws by the end of the year". 3 Many researchers are not so negative about cloning. They are worried that laws banning human cloning will threaten important research. In March, The New Englａｎｄ　Journal of Medicine called any plan to ban research on cloning humans seriously mistaken. Many researchers also believe that in spite of attempts to ban it, human cloning will have become routine by 2010 because it is impossible to stop the progress of science. 4 Is there reason to fear that cloning will lead to a nightmare world? The public has been bombarded (轰炸) with newspaper articles, television shows ａｎｄ　films, as well as cartoons. Such information is often misleading, ａｎｄ　makes people wonder what on earth the scientists will be doing next. 5 Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like. But how would it feel to be a clone among hundreds, the anti-cloners ask Pretty cool, answer the pro-cloners (赞成克隆的人). The United States will introduce____. 【单选题】

A.the nucleus of a cell

B.cloned human beings

C.a human being in two years

D.a law to ban human cloning

E.a report on human cloning

F.heavy media coverage

正确答案:D

答案解析:文章第2段最后一句提到美国通过了禁止克隆人的法律，故选D。

5、Greene spent a brief time at Cambridge.【单选题】
