4．An Israeli law banning too-skinny models went into effect with the start of 2013．The law，approved last March in Israel，requires models to prove they have maintained a Body Mass Index （BMI） of at least 18.5 for three months before a fashion show．That means a woman who is 5'8"tall can weigh no less than 119 pounds．
"This law is another step in the war against eating disorders，"said physician Adatto．"Underweight models，"he explained，"can no longer serve as rold models for innocent young people who copy their false image of being skinny．"
But some critics in this country say it is misguided，focusing on weight instead of health．They also say the Israeli ban is bound to fail because of the strong power of the fashion industry．"I think it's an approach that isn't going to work．"Said eating disorder expert Susan Ice，who worked with an organization wich creates a healthy working environment for models．
But Adatto told the reporter that he began to concern the issue after meeting an aspiring model who looked like she needed to be hospitalized．He said．"I realized that only legislation can change the situation．There was no time to waste，so many girls were dieting to death．"
However，the efforts to regulate models's weight in Spain and Italy have not resulted in part because of difficulties in determining reliable methods of measuring weight and health．"
?Still，folks including Ice say there's no denying that images from Hollywood and the fashion industry can be difficult for young women to deal with．"Certainly I don't believe the modeling industry has caused the rise in eating disorders，but it makes it harder，"she says．"It's a difficult recovery environment，worshiping thinness as the beauty ideal．"
61．What does BMI in the first paragraph refer to？A
A．A measure of body health based on height and weight．
B．A worldwide prize for the healthies model．
C．A new show held by those skinny models．
D．A kind of medicine to cure eating disorders．
62．One benefit the new Israeli law may bring isC．
A．to change the working conditions of models
B．to lower the chance of skinny models's death
C．to prevent models from suffering from eating disorders
D．to provide guidance for women worshiping thinness
63．In the opinion of the critics，the law won't succeed becauseB．
A．it misleads young women to form a bad eating habit
B．the fashion industry is much too influential
C．it doesn't provide a proper approach that can work well
D．it doesn't create a healthy working environment for models
64．What cause Adatto to think that a law was needed to change the situation？D
A．Establishing his fashion-model agent．
B．Metting an ambitious but too skinny model．
C．Being interviewed by a reporter．
D．Seeing a model die from eating disorders．
65．According to the passage，the new Israeli law banning skinny models isD．
A．practical B．acceptable C．reasonable D．controversial．

3．A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct species．The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants-the Asian elephant，African forest elephant and African savanna （热带草原） elephant．
Once they obtained DNA sequences （序列） from two fossils，mammoths and mastodons，the team compared them with DNA from modern elephants．They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths．
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years．The separation of the two species took place around the time of the separation of Asian elephants and woolly mammoths．This result amazed all the scientists．
There has long been a debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species．
Previously，many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants'significant size differences．The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres．The savanna elephant weighs between six and seven tons，roughly double the weight of the forest elephant．But the fact that they look so different does not necessarily mean they are different species．However，the proof lay in the analysis of the DNA．
Alfred Roca，assistant professor in the department of Animal Sciences at the University of Minois，said，"We now have to treat the forest and savanna elephants as two different units for conservation （保护） purpose．Since 1950all African elephants have been conserved as one species．Now that we know the forest and savanna elephants are two very distinct animals，the forest elephant should become a bigger priority for conservation purpose．"

70．One of the fossils studied by the researchers is that ofD．
A．the Asian elephant
B．the forest elephant
C．the savanna elephant
D．the mastodon elephant
71．The researcher's conclusion was based on a study of the African elephant'sA．
A．DNA           B．height          C．weight        D．population
72．Alfred Roca's words were mainly aboutB．
A．the purpose of studying African elephants
B．the conservation of African elephants
C．the way to divide African elephants into two units
D．the reason for the distinction of African elephants
73．Which of the following can be the best title for the passage？C
A．Naturalist's Belief about Elephants．
B．Amazing Experiment about Elephants．
C．An Unexpected Finding about Elephants．
D．A Long scientific Debate about Elephants．

2．Some plants get so hungry that they eat flies，spiders，and even small frogs．What's more amazing is that these plants occur naturally （in special environments） in every state．In fact，they're found on every continent except Antarctica．
You've probably seen a Venus'flytrap．It's often sold in museum gift stores，department stores，and even supermarkets．A small plant，it grows 6to 8inches tall in a container．At the end of its stalks （茎） are specially modified leaves that act like traps．Inside each trap is a lining of tiny trigger （触发） hairs．When an insect lands on them，the trap suddenly shuts．Over the course of a week or so，the plant feeds on its catch．
The Venus'flytrap is just one of more than 500species of meat-eating plants，says Barry Meyers-Rice，the editor of the International Carnivorous （食肉的） Plant Society's Newsletter．Note：Despite any science-fiction stories you might have read，no meat-eating plant does any danger to humans．
Dr．Meyers-Rice says a plant is meat-eating，only if it does all four of the following："attract，kill，digest，and absorb"some form of insects，including flies，butterflies，and moths．Meat-eating plants look and act like other green plants---well，most of the time．
All green plants make sugar through a process called photosynthesis （光合作用）．Plants use the sugar to make food．What makes"meat-eating"plants different is their bug-catching leaves．They need insects for one reason：nitrogen （氮）．Nitrogen is a nutrient that they can't obtain any other way．While almost all green plants on our planet get nitrogen from the soil，"meat-eating"plants can't．They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity．So they've come to rely on getting nitrogen from insects and small animals．In fact，nutrient-rich soil is poisonous to"meat-eating"plants．Never fertilize them!But don't worry，either，if they never seem to catch any insects．They can survive，but they'll grow very slowly．

66．According to the passage，carnivorous plantsD．
A．only grow in wild field
B．are rare to see
C．are as common as flies
D．cannot grow on Antarctica
67．Venus'flytrap preys on insects byC．
A．its numerous long and thin stalks
B．a container where it grows
C．its insect-catching leaves
D．the lining of tiny trigger hairs
68．We can conclude from the third paragraph thatD．
A．carnivorous plants are dangerous
B．carnivorous plants are fictional
C．carnivorous plants occasionally eat books
D．carnivorous plants are harmless to humans
69．In the eyes of the author，which of the following statements is TRUE？B
A．Carnivorous plants cannot grow in acid soil．
B．Carnivorous plants can grow in nutrient-poor soil．
C．Carnivorous plants will die if they cannot catch any insects．
D．Carnivorous plants can get nitrogen from nutrient-rich soil．
