阅读理解（二）1、 Is dark chocolate healthy? Yes,dark chocolate has compounds(化合物) that offer health benefits and can be enjoyed without guilt, even on a daily basis. But the amount matters, since too many bites can contribute to extra fat, sugar and calories and get rid of its health benefits.Dark chocolate is rich in cocoa, which contains compounds known as flavanols(黄烷醇). At high levels, cocoa flavanols have been shown to help lower blood pressure and the risk of diabetes. Dark chocolate has the highest amount of cocoa flavanols: milk chocolate has lens, and white chocolate has none.But while cocoa flavanols in dark chocolate make it a healthful treat they give it a biter flavor. Producers may process chocolate to make it more delicious, but doing so can remove some of these beneficial compounds,said Matt Hartings, an American professor. In spite of this,dark chocolate is still a healthier choice than milk chocolate, which tends to have more sugar. Additionally, cocoa powder contains minerals. So you can enjoy a piece of dark chocolate even after a meal. Just keep the following in mind.First, buy chocolate that has at least 60% cocoa. "Generally speaking,the higher the percentage, the more flavanols. These higher-percentage chocolates have the added benefit over the lower percentages and milk and white chocolates because they contain less sugar and less fat,” Hartings said.Second, if possible, choose natural cocoa over Dutch processed cocoa, which is treated with an alkali(碱). This gives chocolate a milder flavor but removes healthful flavanols.And finally, to keep weight in check, limit to 30 grams of dark chocolate daily, or about 150 calories.1.Dark chocolate is healthy mainly because of the existence of _______.A.rich mineralsB.less sugarC.cocoa flavanolsD.fewer calories2.What does the underlined word “treat” in Paragraph 3 mean?A.Something enjoyable.B.A salt-free diet.C.Food paid by others.D.A cure for an illness.3.What can we learn from the text?A.Cocoa flavanols leads to high blood pressure.B.White chocolate is good for health.C.One can feel free to eat dark chocolate.D.Alkali can affect flavanol s’ content.4.What’s the author’s purpose in writing the text?A.To show his love for dark chocolate..B.To promote the sales of chocolate.C.To provide facts about dark chocolate.D.To make a distinction among chocolates.2、 Many of us have reached in our pockets,feeling a vibration(振动), wrongly believing our mobile phones have just rung. The phenomenon even has a name: ‘phantom vibration syndrome’—and found it is surprisingly common.Now scientists believe that we are so alert(警觉) for phone calls and messages we are misinterpreting slight muscle spasms(痉挛) as proof of a call. Robert Rosenberger, an assistant professor at the Georgia Tech Institute of Technology has studied the delusional calls. He said sufferers describe a vague tingling feeling which they think is their mobile phone indicating it has received a text message or call while on “silent”. But when the device is retrieved,there was no one on the other end.Dr. Rosenberger said, “ I find so many people say, This happens to me, but I t hought I was the only one. I thought I was odd.” It seems that the syndrome particularly affects people at the beck and call of mobile phones or pagers. A 2010study by Michael Rothberg and colleagues found that nearly 70 per cent of doctors at a hospital in Massachusetts suffered phantom vibrations. A more recent study of US college students found the figure was as high as 90 per cent.While the odd feeling is widespread, it does not seem to be considered a grave problem. Dr. Rosenberger said,“It’s not actually a syndrome in a technical sense. That’s just the name that’s got stuck to it." He added, “Only 2 per cent of people consider it a problem."While widespread, the scientific community has not yet invested much effort in getting to the bottom of why we suffer phantom calls. Dr. Rosenberger said, "People are guessing it has something to do with nervous energy. The cognitive(认知的) scientists are talking about brain chemistry, cognitive pathways changing. But it’s not like they have brain scans to g o on." He said, “We have a phone call in our pocket all the time and it becomes sort of an extension of ourselves. We have this sort of readiness to experience a call. We feel something and we think, OK, that could be a call.”1.Why do some people mistake slight muscle spasms for a call?A.They all have a vivid imagination.B.They are sensitive to calls and messages.C.There are few calls and messages in their life.D.Sight muscle spasms affect them more than other people.2.Which of the following are more likely to have phantom vibration syndrome than others?A.Doctors.B.University professors.C.College students.D.The cognitive scientists.3.In Dr. Rosenberger’s opinion, phantom vibration syndrome________.A.isn’t a kind of disease actuallyB.is considered a problem by most peopleC.is a serious problem ignored by peopleD.has something to do with brain chemistry3、 It goes without saying, but bears repeating, there are too many cats and dogs without homes. While there are countless shelters and rescue centers that exist, some potential pet owners look to pet shops to find their furry friends. All too often, however, these animals come from puppy and kitten mills (繁殖场) that treat the creatures in cruel ways. San Francisco, however, is doing their part to stop this abuse with pet store adoption. Officials recently voted to ban the sale of non-rescue dogs and cats in local shops.The effect is two-fold. One, it will stop the popularity of the large-scale mills, which are famous for the miserable conditions cats and does are kept in. Two, it will help facilitate the adoption of thousands of animals that are waiting for their forever homes in San Francisco shelters. District 4 Supervisor Katy Tang, who serves on the San Francisco Board of Supervisors, supported law-making on the ban. “Dogs and cats sold in pet stores often come from inhumane puppy and kitten mills that treat animals with no regard for their health or well-being”, she wrote on Facebook. In her message, she also called on the U. S. Agriculture Department to reinstate information on its website that documents these types of animal cruelty cases—it was removed earlier this month.San Francisco’s law-making is a victory for those concerned about animal rights, and they aren’t the first city to pass this type of measure. Los Angeles, San Diego, Chicago, Philadelphia, Boston, and Austin also have similar laws in place, with hopefully more places to follow suit.1.What happened to some dogs and cats before they got in the pet stores?A.They were treated cruelly.B.They were abandoned in streets.C.They received warm welcome.D.They were raised in shelters and rescue centers.2.Which of the following may Katy Tang agree with most?A.People should adopt the dogs and cats.B.Animals are too cruel to humans being.ernment can choose to kill all the dogs and cats.D.It is not right to ban the sale of non-rescue dogs and cats in local shops.3.What does the underlined word “reinstate” in Paragraph 2 mean?A.updateB.replaceC.post againD.download4.What does the last paragraph mainly focus on?A.No Chinese city joins this type of movement.B.San Francisco is the last city to ban pet stores.C.Americans care about animals more than humans.D.More and more cities are involved in animal rights.4、In today’s global world, more and more people travel to foreign countries. Cross cultural awareness and an understanding of foreign etiquette is important if you want to succeed as an international business person. Behaviour that is polite at home may be considered rude in another country. In particular, by learning about dining etiquette and table manners, you can avoid offending people and this can directly influence your business success.John Smith’s book The Perfect Guest is a goldmine of inf ormation for the globe - trotting business person. There are chapters dedicated to all the main problem areas of dining etiquette and entertaining in different countries and tips on how to cope with embarrassing situations.These are some of the areas which are covered in the book.Seating arrangementsWhether you are eating at a restaurant or at someone’s home, there may be a fixed protocol of who sits where. Do men and women sit together? Is there a hierarchy according to age or status? Rules vary greatly. For example, inKorea, it is customaryto offer the best seat to the most senior person; in theUS, there are no specific seating rules. If you don’t know where to sit, wait until your host shows you.ConversationIs the dining table the right place to have a conversation or is the meal taken in silence? In France, for instance, the meal is a social affair with loud animated conversations and most topics are acceptable, including business. In Japanor Vietnam, on the other hand, only quiet conversation is acceptable and business is never conducted at the dinner table.FoodWhat type of food is popular? Is it polite to remark on the food? Should you eat everything or leave some food on your plate? Is it polite to ask for the salt an d pepper if it isn’t on the table? And how can you deal with a food delicacy that you find disgusting? In Europe, it is polite to eat everything on your plate whereas this would be considered rude in Egypt. If you clean your plate, it will be filled up again immediately.1.Who is most likely to find the information useful?A.A business person.B.A scientist.C.A student.D.A soldier.2.When you are a guest in the US, where should you sit?A.In the best seat.B.Where your host shows you to sit.C.Wherever you like.D.Next to the senior.3.You leave food on your plate in Egypt ________.A.to show that you have eaten enoughB.so that there arc leftovers for the catC.to show that you don’t like the foodD.but it is considered rude4.The passage mainly tells us _______.A.cross cultural dining etiquetteB.cultural differences around the worldC.how to improve cultural awarenessD.why the book is worth buying5、In fairy tales, it's usually the princess that needs protecting. At Google in Silicon Valley, the princess is the one defending the castle. Parisa Tabriz is a 31-year-old with perhaps the most unique job title in engineering- “Google Security Princess”. H er job is to hack into the most popular web browser (浏览器) on the planet, trying to find weaknesses in the system before the “black hats” do. To defeat Google's attackers, Tabriz must firstly think like them.Tabriz's role has evolved dramatically in the eight years since she first started working at Google. Back then, the young graduate from Illinois University was one of 50 security engineers---today there are over 500.Cybercrime (网络犯罪) has come a long way in the past decade - from the Nigerian Prince Scam to credit card theft. Tabriz's biggest concern now is the people who find bugs in Google's software, and sell the information to governments or criminals. To fight against this, the company has set up a Vulnerability Rewards Program, paying anywhere from $100 to $ 20,000 for reported mistakes.It's a world away from Tabriz's computer-free childhood home in Chicago. The daughter of an Iranian-American doctor father, and Polish-American nurse mother, Tabriz had little contact with computers until she started studying engineering at college. Gaze across a line-up of Google security staff today and you'll find women like Tabriz are few and far between(稀少的) ---though in the last few years she has hired more female tech geniuses. She admits there's an obvious gender disequilibrium in Silicon Valley.Funnily enough, during training sessions Tabriz first asks new colleagues to hack into not a computer, but a vending machine. Tabriz's job is as much about technological know-how (专门知识) as understanding the psychology of attackers.1.What can we learn about Tabriz from the passage?A.She was the first female engineer at Google.B.She must think differently so as to defeat the attackers.C.Her job relates to not only technology but also psychology.D.Her frequent contact with computers in childhood benefits her a lot.2.Why has Google set up a Vulnerability Rewards Program?A.To protect Google against cybercrime.B.To monitor the normal operation of Google.C.To help the government locate the cybercriminals.D.To raise people's awareness of personal information safety.3.What does the underlined word “disequilibrium” in Paragraph 4 refer to?A.Imbalance.B.Preference.C.Difference.D.Discrimination.4.Which of the following could be the best title of this passage?A.What leads to cybercrimeB.The "Security Princess" who guards GoogleC.Measures taken by Google to protect its usersD.How to become an excellent security engineer6 、Over seven months have passed since Panamanian officials launched an expansion of the world famous Panama Canal. Officials agreed to the expansion so that many of the world’s largest cargo ships (货船) could easily pass through the canal. Yet the $ 5.25-billion project has problems. It says ships still continue to rub against the canal’s walls and wear out its defenses designed to protect both shipping and the waterway.A dangerous systemThe canal links two oceans-the Atlantic and the Pacific-through a system of locks (船闸). The locks are like steps. They raise and lower ships from one part of the waterway to another on their trip from ocean to ocean.With the old locks, which are still in use, large ships would be tied to powerful engines on both sides. These engines help to keep the ships in the center of the canal. In the new locks, the ships are tied to tugboats (拖船). One tugboat is tied to the front of the ship, with the other tied to the back. These boats then guide the ships through the canal.At first, pilots of the cargo ships and tugboat operators would sometimes try to rub the boats against the canal walls as a way to keep the ships straight. But this caused damage to rubber padding (垫料) lining the walls.Not enough trainingEven before the expanded canal opened in June 2016, tugboat operators had expressed concern about the new system. Many asked for more training. The fears and dangers remain, although the boats are going through.The Panama Canal Authority reports that, between June 2016 and January 2017, there were only 15 incidents that resulted in damage to locks or ships. That represents about 2 percent of the 700 times ships that have sailed through the expanded canal.Pilots have argued they should be replaced with a system of floating bumpers (减震) like those used in some European locks. Officials say they plan to continue operating with the current system of defenses, but changes could happen in the future.1.What is the difference between the new locks and the old ones?A.The old locks don’t need rubber padding as defenses.B.The new locks need tugboats tied to both sides of the ships.C.The new locks are easier for the largest ships to pass through the canal.D.The old locks need powerful engines to drag the ships through the canal.2.What is the Panama Canal Authority’s attitude towards the expanded canal?A.Cautious.B.Critical.C.Positive.D.Doubtful.3.What can we learn about the current system of defenses?A.No ships shall rub against the canal walls to protect it.B.Nothing will be done at present to improve it.C.More training will be given to pilots for it.D.A new system will replace it.7、 Stonehenge,the world-famous circle of stone columns may have had a brother.A much bigger, older brother.University of Bradford researchers announced they had discovered about 100 stones covering several acres thought to have been built around 4,500 years ago. The Stonehenge Hidden Landscapes Project discovered the monument, which is near Durrington Walls,also k nown as “superhenge”. Stonehenge,which is believed to have been completed 3,500 years ago,is about 2 miles away. “What we are starting to see is the largest surviving stone monument, preserved underneath a bank, that has ever been discovered in Britain and possibly in Europe,” Vince Gaffney.The evidence was found under 3 feet of earth. Some of the stones are thought to have stood 15 feet tall before they were toppled. “Our radar data has shown an amazing row of up to 90 standing stones,a number of which have survived after being pushed over, and a large bank placed over the stones,” said professor Wolfgang Neubauer, director of the Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology.“In the east,up to 30 stones. " have survived below,” he said. “The extraordinary scale and details of the evidence produced by the Stonehenge Hidden Landscapes Project, which the new discoveries at Durrington Walls, is changing greatly our understanding of Stonehenge and the world around it,” Neubauer added.“Everything written before about the Stonehenge landscape and the ancient monuments within it will need to be rewritten,” said Paul Garwood, a scientist andlead historian on the project at the University of Birmingham. The findings were announced on the first day of the British Science Festival being held at the University of Bradford.pared to the Stonehenge,the superhenge is believed to be _______.A.1,000 years earlierB.1,000 years laterC.3,500 years earlierD.4,500 years earlier2.What do researchers think of the superhenge?A.It is the biggest monument discovered in the world.B.It was built much later than the Stonehenge.C.It is the largest surviving stone monument found in England.D.It is better protected than the Stonehenge.3.What do the underlined word “toppled” most probably mean?A.Set up.B.Pushed down.C.Moved away.D.Brought up.4.What is the best title of the passage?A.The southern England has many historic sitesB.The British Science Festival will be held againC.Bigger Brother to Stonehenge has been discoveredD.The Project at the University of Birmingham8、 No student of a foreign language needs to be told that grammar is complex. By changing the order of the words and by adding a range of auxiliary verbs (助动词) and suffixes (后缀), we can turn a statement into a question, state whether an action has taken place or is soon to take place, and perform many other word tricks to convey different meanings. However, the question which many language experts can’t understand and explain is—who created grammar?Some recent languages evolved due to the Atlantic slave trade. Since the slaves didn’t know each other’s languages, they developed a make-shift language called a pidgin. Pidgins are strings of words copied from the language of the landowners. They have little in the way of grammar, and speakers need to use too many words to make their meaning understood. Interestingly, however, all it takes for a pidgin to become a complex language is for a group of children to be exposed to it at the time when they learn their mother tongue. Slave children didn’t simply copy the strings of words used by their elders. They adapted their words to create an expressive language. In this way complex grammar systems which come from pidgins were invented.Further evidence can be seen in studying sign languages for the deaf. Sign languages are not simply a group of gestures; they use the same grammatical machinery that is found in spoken languages. The creation of one such language was documented quite recently in Nicaragua. Previously, although deaf children were taught speech and lip reading in the classrooms, in the playgrounds they began to invent their own sign system, using the gestures they used at home. It was basically a pidgin and there was no consistent grammar. However, a new system was born when children who joined the school later developed a quite different sign language. It was based on the signs of the older children, but it was shorter and easier to understand, and it had a large range of special use of grammar to clarify the meaning. What’s more, they all used the signs in the same way. So the original pidgin was greatly improved.Most experts believe that many of the languages were pidgins at first. They were initially used in different groups of people without standardization and gradually evolved into a widely accepted system. The English past tense—“ed” ending—may have evolved from the verb “do”. “It ended” may once have been “It end-did”. It seems that children have grammatical machinery in their brains. Their minds can serve to create logical and complex structures, even when there is no grammar present for them to copy.1.What can be inferred about the slaves’ pidgin language?A.It was difficult to understand.B.It came from different languages.C.It was created by the landowners.D.It contained highly complex grammar.2.What is the characteristic of the new Nicaraguan sign language?A.No consistent signs were used for communication.B.Most of the gestures were made for everyday activities.C.The hand movements were smoother and more attractive.D.The meaning was clearer than the previous sign language.3.Which idea does the author present in the last paragraph?A.English grammar of past tense system is inaccurate.B.Children say English past tense differently from adults.C.The thought that English was once a pidgin is acceptable.D.Experts have proven that English was created by children.4.What is the best title for the passage?A.The Creators of GrammarB.The History of LanguagesC.Why Pidgins Came into BeingD.How Grammar Systems Are Used答案以及解析1答案及解析：答案：1.C; 2.A; 3.D; 4.C解析：1.细节理解题。
