There is one passage in this section with 5 statements. Go over the passage quickly and answer the questions on the Answer Sheet. For questions 1-5, mark Y (for YES) if the statement agrees with the information given in the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. When was the last time you saw a frog? Chances are, if you live in a city, you have not seen one for some time. Even in wet areas once teeming with frogs and toads, it is becoming less and less easy to find those slimy, hopping and sometimes poisonous members of the animal kingdom. All over the world, even in remote jungles on the far side of the globe, frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise. Are amphibians simply over-sensitive to changes in the ecosystem? Could their rapid decline in numbers be signalling some coming environmental disaster for us all? This frightening scenario is in part the consequence of a dramatic increase over the last quarter of a century in the development of once natural areas of wet marshland: home not only to frogs but to all manner of wildlife. Yet, there are no obvious reasons why certain frog species are disappearing from rainforests in the Southern Hemisphere which are barely touched by human hands. The mystery is unsettling to say the least, for it is known that amphibian species are extremely sensitive to environmental variations in temperature and moisture levels. The danger is that planet Earth might not only lose a vital link in the ecological food chain (frogs keep populations of otherwise pestilent insects at manageable levels), but we might be increasing our output of air pollutants to levels that may have already become irreversible. Frogs could be inadvertently warning us of a catastrophe. An example of a bizarre occurrence regarding a species of frog dates from the summer of 1995, when “an explosion” of multi-coloured frogs of the species Rana klepton esculenta occurred in the Netherlands. Normally these frogs are brown and greenish-brown, but some unknown contributory factor is turning these frogs yellow and / or orange. Nonetheless, so far, the unusual bi- and even tri-coloured frogs are functioning similarly to their normal-skinned contemporaries. It is thought that frogs with lighter coloured skins might be more likely to survive in an increasingly warm climate due to global warming. One theory put forward to explain extinct amphibian species that seems to fit the facts concerns the depletion of the ozone layer, a well-documented phenomenon which has led to a sharp increase in ultraviolet radiation levels. The ozone layer is meant to shield the Earth from UV rays, but increased radiation may be having a greater effect upon frog populations than previously believed. Another theory is that worldwide temperature increases are upsetting the breeding cycles of frogs. Statements: 1．Biologists are unable to explain why frogs are dying out. 2．Attempts are being made to halt the development of wet marshland. 3．Frogs are important in the ecosystem because they control pests. 4．It is not known why Dutch frogs are changing colour. 5．It is a fact that frogs’ breeding cycle has been upset by worldwide increases in temperature.

7月1日，无权代理人甲以A公司的名义签发一张100万元的转账支票给B公司，该支票上记载收款人为B公司，付款人为乙银行，甲在该支票上签章。7月2日，B公司在明知甲没有代理权的情况下，仍将该支票背书转让给不知情的C公司，以支付货款。7月3日，C公司为向D公司支付租金，将该支票交付给D公司，但未在该支票上背书和签章。D公司因急需向E公司支付工程款，D公司便私刻了C公司法定代表人张某的人名章和C公司财务专用章，加盖于背书栏，并直接记载E公司为被背书人。E公司不知有假，接受了票据。 7月8日，E公司向乙银行提示付款，被．拒绝付款。 要求： 根据上述内容，分别回答下列问题：E公司能否向C公司行使追索权？并说明理由。
