Are you afraid of sharks? You shouldn’t be! Below we cleared up the main myths about one of the world’s most perfectly formed creatures …
All sharks are the same.
This is absolutely not true. There are nearly four hundred species of sharks and they vary widely in habitat, size, features, diet and lifestyle. They range from the cigar shark, which is about 15 centimetres long, to the whale shark, which can be up to about nine meters long. More than 50 percent of sharks are less than a metre long and more than 90 percent are less than two metres long. And their habitat ranges from shallow to deep water and from the Arctic to the Tropic.
___________________
This is not true, either. In fact, many shark populations are decreasing. The chief reason for this is that hundreds of thousands of them are caught in fishing nets. Depending on where they are caught. They are either killed for their fins(鳍), which are used in shark’s fin soup, or they are tossed back into the sea because they are unwanted. Almost all sharks which are discarded in this way die. Also, sharks mature late in life and produce very few young. If the current reduction in numbers continues, the ecological balance of the oceans will be severely threatened.
Sharks will always attack you
This is nonsense. The chances of being attacked by a shark are minimal. You are 250 times more likely to be killed by lightning than by a shark, and your chances of being killed by lightning are practically zero.
However, if you are planning to take a swim in shark territory, then follow these simple rules:
Avoid swimming at dawn or duck when visibility decreases.
Avoid areas where there are breaking waves. Turbulent(汹涌的) water makes it difficult for sharks to see and determine whether you are prey(猎物).
Do not wear jewellery in the water. Sharks are attracted to shiny fishes, and jewellery may resemble their scales(鳞片).
Do not swim near schools of small fish, which are the favorite food of some sharks.
68. The underlined word “myths” in the first paragraph means ____.
A. an idea or story that many people believe but which is not true
B. something that is impossible to understand or explain or about which little is known
C. a feeling of surprise
D. something that you are curious to know
69. From the passage we can learn sharks ____.
A. look alikeB. are dangerous
C. usually live in deep sea D. hardly attack people
70. Which of the following is proper for the blank in the third paragraph?
A. Sharks’ fin soup is nutritious
B. There are too many sharks in the sea
C. Many shark populations are decreasing
D. Sharks produce many young
71. Which of the following rules should you follow when you’re going to swim in shark areas?
A. Don’t swim before day breaks.
B. Choose areas where there are big waves.
C. Wear something shiny when swimming.
D. Choose areas where there are many small fish.

Two Earthquakes in Two Months:
Comparing the Quakes in Haiti (海地) and Chile (智利)
Overview (概要) How do the earthquakes in Chile and Haiti compare? Here, students perform a gallery walk to learn more about the earthquakes from a specific point, and then do a specific research and presentation project or response activity. Finally, they seek answers to their unanswered questions.
Materials Print copies of photographs, charts, documents and other visuals to display, as described below; computer (s) with Internet access (optional), research materials, handouts.
Warm-up Choose and prepare a “gallery” of photographs, graphics, news reports and other materials to display around the room to enable students to consider the 2010 earthquake in Chile.
Depending on course program, choose materials for the gallery that provide a window on the two quakes, through one of the following specific points, or the focus of your choice:
Earthquakes through History Putting the 2010 Chilean and Haitian quakes into historical view related to other earthquakes, including the 1960 Chilean quake and the 2004 Asian earthquake and tsunami.
Rescue and Aid Considering domestic and international response to the disasters by militaries, governments and aid organizations, including rescue and recovery as well as efforts to provide food, water, health care and shelter to those affected.
Related The article Underwater Plate Cuts 400 Mile Gash compares several earthquakes:
Mr. Lin figured that the quake on Saturday was 250 to 350 times more powerful than the Haitian quake.
But Paul Caruso noted that at least on land, the effects of the Chilean tremor (震动) might not be as bad. For one thing, he said, the quality of building construction is generally better in Chile than in Haiti. And the fact that the quake occurred offshore should also help limit the destruction. In Haiti, the rupture (断裂) occurred only a few miles from the capital, Port-au-Prince. The rupture on Saturday was centered about 60 miles from the nearest town, Chillan, and 70 miles from the country’s second-largest city, Concepción.
Read the article using the following questions.
Questions For discussion with others and reading comprehension:
How does the 2010 Chilean earthquake compare to the 1960 Chilean earthquake?
Why do scientists believe that the 2010 Chilean earthquake will not cause the same level of damage as January’s Haitian earthquake did?
How does the 2010 Chilean earthquake compare to the 2004 Indonesian earthquake?
What reasons do scientists give to explain why the Indonesian quake caused so much more damage than the recent Chilean earthquake?
64. Which of the following shows one of the reasons for slighter losses in Chile than in Haiti?
A. Position:
B. Power:
65. We can infer that the article Underwater Plate Cuts 400 Mile Gash includes ________.
A. the causes of the 2010 Chilean earthquake and the 1960 Chilean earthquake
B. the comparison between the 2010 Haitian and the 2004 Indonesian earthquakes
C. the reason for the 2010 Chilean quake being more powerful than January’s Haitian earthquake
D. the reason for less damage in the 2010 Chilean quake than in the 2004 Indonesian earthquake
66. What is the passage most likely to be?
A. A program for research. B. A guide to earthquake study.
C. An advertisement for students. D. An introduction to quakes.

I believe that animals possess greater intelligence than most people think. But plants? I"ve never considered the possibility of plant intelligence. The idea seems absurd.
Yet I"ve had friends argue that plant intelligence might exist. "What are the differences between plants and animals?" they ask, and then they argue about certain species that seem to share the intelligence of both plants and animals.
New research suggests that plants communicate via "networks". Plant communication is not idea, and cannot indicate that its is a kind of intelligence, but it is still interesting.
Recent research from Vidi researcher Josef Stuefer at the Radboud University Nijmegen shows that plants have their own chat systems that they can use to warn each other. Therefore plants are not boring and passive organisms that just stand there waiting to be cut down or eaten up. Many plants form internal communication networks and are able to exchange information networks and are able to exchange information efficiently.
Many herbal plants such as strawberries and clovers (三叶草)naturally form networks.
Individual plants remain connected with each other for a certain period of time by means of runners (plant stems that grow along the ground and put down roots to form new plants). These connections enable the plants to share information with each other via internal channels. They are therefore very similar to computer networks. But what do plants chat to each other about?
Recently Stuefer and his colleagues were the first to prove that clover plants warn each other via the network links if danger is nearby . If one of the plants is attacked by caterpillars (毛虫),the other members of the network are warned via an internal signal. Once warned the intact (完好无损的)plants strengthen their chemical and mechanical (机体的)resistance so that they are less attractive to advancing caterpillars. Thanks to this early warning system, the plants can stay one step ahead of their attackers. The research has shown that this significantly limits the damage to the plants.
Again, I don"t believe this reflects intelligence, but it"s is certainly fascinating.
66.The author thinks that the plant communication .
A.is absolutely a new idea
B.is a sign of plant intelligence
C.is related to animal communication
D.is interesting and fascinating
67.Clover plants warn each other when danger is nearby by .
A.making sounds
B.releasing chemicals
C.strengthening mechanical resistance
D.sending internal signals
68.Which of the following statements about the research is NOT true?
A.Most plants have no chat system and are passive organisms.
B.Individual plants can also remain connected with each other.
C.The communication between clover plants can protect them from damage.
D.The research is the first to show how clover plants warn each other.
69.The author"s attitude towards plant intelligence is
A. unconcerned B. doubtful C. positive D. hopeful
70" What"s the best title for the passage?
A.Does Plant Communication Really Exist?
B.Some Discoveries About Clover Plant
C.Does Plant Communication Imply Intelligence?
D.A New Study on Plant Communication

Shopping carts are such a ubiquitous presence in stores today that it is hard to imagine a time without them.And yet it wasn’t until the year 1937 when the first shopping cart was introduced.
The shopping cart was the brainchild of Sylvan Goldman,the owner of a grocery food chain in 0klahoma.Goldman noticed that his customers struggled to carry their food in heavy hand-held baskets.He decided there must be an easier way for his costomers to carry the food around in his supermarkets.Observing a folding chair, Goldman decided to use that as the prototype for his new shopping cart.
With the aid of a mechanic, Fred Young ,Goldman designed the first shopping cart based on the folding chair.Wheels were placed where the bottoms of the chair legs were. In place of the chair seat, Young and Goldman , placed two metal baskets on top of each other. This cart could be stored by folding it up like a folding chair.
At first there was a bit of difficulty getting the public to accept shopping carts.Men thought using them was effeminate(女人气的)while younger women considered the use of the shopping carts to carry products around to be somewhat unstylish.Goldman solved this problem by hiring men and women models to use shopping carts in his stores.In addition,store greeters instructed customers in how to use the shopping carts.In short order,the shopping carts became incredibly popular because it made shopping much easier for customers.By 1940 the popularity of shopping carts had grown to such an extent that there was a 7 year waiting list in store orders for new shopping carts.

B. People thought it unnecessary to use them because they never did much shopping.
C. The early shopping carts were too difficult to use.
D. Only men and women models were supposed to use such modern things.
48.. How popular did Goldman’s invention finally become?
A.Men and women models used shopping carts in his stores.
B.Store greeters instructed customers in how to use the shopping carts.
C.Some stores had to wait several years to get his shopping carts.
D.His shopping carts had improved so much that both men and women liked to use them.

Time spent in a bookshop can be most enjoyable, whether you are a book—lover or merely go there to buy a book as a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings.
The desire to pick up a book with an attractive dust jacket is irresistible, although this method of selection ought not to be followed, as you might end up with a rather dull book.
You soon become interested in some book or other, and usually it is only much later that you realize you have spent far too much time there and must dash off to keep some forgotten appointment—without buying a book, of course.
This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can wander round such places to your heart’s content. If it is a good shop, no assistant will approach you with the inevitable greeting:“Can I help you, sir?” You needn’t buy anything you don’t want. In a bookshop an assistant should remain in the background until you have finished browsing. Then, and only then, are his services necessary. Of course, you may want to find out where a particular section is, but when he has led you there, the assistant should retire discreetly(谨慎地) and look as if he is not interested in selling a single book.
You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on, say ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass—rubbing—something which had only slightly interested you up till then. This volume on the subject, however, happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very dangerous. Apart from running up a huge account, you can waste a great deal of time wandering from section to section.
63.The underlined phrase “dust jacket” means_______.
A.a kind of clothes B.a paper cover of a book
C.a dusty book D.a title of a book
64.You may spend too much time in a bookshop because_______.
A.the dust jackets are very attractive
B.you start reading one of the books
C.it is raining outside
D.you have to make sure you won’t buy a dull book as a present
65.In a good bookshop_______.
A.all the books there are interesting B.the assistant greets you in a warm way
C.your heart is satisfied D.you feel that you are in a music shop
66.The best title for this passage may be_______.
A.The Attraction of Bookshops B.How to Spend Your Time
C.Bookshops and Their Assistants D.How to Select Books
