D A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control . This idea is dangerous. Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast and is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing. Some people go even further. They say that despite the moral and legal objections, whatever is scientifically possible will be done-somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it fuels a sense of hopelessness and discourages then from making efforts to build a safer world. In our interconnected world, the lack of agreement in and out of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict. Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the untied efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future. 76.What can we conclude from the recent study? A.People think highly of science. B.People hold mixed opinions about science. C.Science is getting dangerously out of control. D.Science is used for both good and bad purposes. 77.According to the passage, what will happen if we hold that science is getting beyond control? A.The development of science will hopelessly slow down. B.Businesses will have even greater influence on science. C.The public will lose faith in bringing about a bright future. D.People will work more actively to put science under control. 78.The discussion should reach beyond scientific societies because . A.scientists have failed to predict the outcomes B.the ties between different areas need strengthening C.united efforts are necessary for the development of science D.people need to work together to prevent the bad use of science 79.What is the main idea of the passage? A.Science and its applications bring us many dangers. B.The development of science mostly lies in people’s attitudes. C.Mankind can largely take control of science with their efforts. D.The future of science will be influenced by the dangerous ideas. Section C Directions: Read the following text and choose the most suitable heading from A – F for each paragraph.

题目列表(包括答案和解析)

The Post Hotel in Austria is clean but the price is high. If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers are overweight, and some of this is because of their bad eating habits. Most teenagers love food with a lot of fat, oil, salt, and sugar. People often call this kind of food “junk food".?

But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don't have breakfast before they go to school。.During the day, some don't have a proper meal for lunch. In a recent survey at one school, scientists found that over two thirds of the students didn't follow a healthy diet. They didn't like vegetables, and many of them didn't like to eat fruits. They preferred(更喜欢) to eat food with a lot of salt, sugar, or fat.

Parents today also worry about their children's diet. Some doctors give the following advice:

★ Teenagers shouldn't eat too much junk food.

★ Teenagers shouldn't eat food with too much salt. Salt can cause high blood pressure(高血压)in the future.

★ Teenagers should eat food with less fat, oil, and sugar.

★ Teenagers need to eat some fruits and vegetables every day. Fruits and vegetables are rich in vitamins(维生素)and have little fat.

★ Teenagers need to drink more milk. Milk will help their bones grow.?

★ Teenagers need to eat breakfast every day. This is good for their body and mind.

A recent study offers a picture of how dangerous it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal(致命的)accident as a teenager driving alone. However, the possibility of death for drivers between 30 and 59 decreases with each additional (added) passenger.
  It was also found that the death rates for teenage drivers increased greatly after 10 p.m., and especially after midnight. With passengers in the car, the driver was even more likely to die in a late night accident.
  Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with “really stupid behavior” than with just a lack of driving experience. Both he and the author of the study believe that the way to help solve the problem is to have states setting up so-called graduated licensing systems(等级执照制). A graduated license requires that a teenager first prove that he/she is able to drive in the presence of an adult, followed by a period of driving with a limited number of passengers, before graduating to full driving on his own. About half of the states now have some sort of graduated licensing system in place. The systems have reduced teenage driver crashes(相撞), according to recent studies.
【小题1】Which of the following situations is most dangerous according to the passage?

A.Adults giving a lift to teenagers on the highway after 10 p.m.
B.A teenager driving after midnight with passengers in the car.
C.Adults driving with three or more teenage passengers late at night.
D.A teenager getting a lift from a stranger on the highway at midnight.
【小题2】According to Robert Foss, the high death rate of teenage drivers is mainly because __.
A.their preference for driving at night
B.their lack of driving experience
C.their careless way of driving
D.their driving with passengers

The iPhone is a line of smartphones designed and marketed by Apple Inc. It runs Apple's iOS mobile operating system, known as the "iPhone OS" until mid-2010, shortly after the release of the iPad. The first generation iPhone was released on June 29, 2007, the most recent iPhone, the seventh-generation iPhone 5S, on September 20, 2013. The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and cellular connectivity (2G, 3G, 4G, and LTE).

An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive emails, look through the web, send texts, and receive visual voicemail. Other functions—games, reference, GPS navigation, social networking, etc.— can be enabled by downloading apps; as of 2012[update], the App Store offered more than 775,000 apps by Apple and third parties.

There are six generations of iPhone models, each accompanied by one of the six major releases of iOS. The original 1st generation iPhone was a GSM phone, and established design precedents, such as a button placement that has persisted through all models and a screen size maintained until the launch of the iPhone 5 in 2012. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a faster processor and a higher-resolution camera that could record video at 480p. The iPhone 4 featured a higher-resolution 960 × 640 "retina display", a VGA front-facing camera for video calling and other apps, and a 5-megapixel rear-facing camera with 720p video capture. The iPhone 4S upgrades to an 8-megapixel camera with 1080p video recording, a dual-core processor, and a natural language voice control system called Siri. IPhone 5 features the new A6 processor, increases the size of the Retina display to 4 inches, and replaces the 30-pin connector with an all-digital Lightning connector.

The resounding sales of the iPhone have been credited with reshaping the smart phone industry and helping make Apple one of the world's most valuable publicly trading companies in 2011–12. However, there has been criticism of the company's outsourcing and move of jobs from the US to China. Apple and its manufacturing contractor Foxconn have received criticism due to poor working conditions at the assembly plant in China.

Are you carrying too much on your back at school? You’re not alone. Back experts in the United States are worried that young students are having back and neck problems as a result of carrying too much in their backpacks (schoolbags)
“It hurts my back when I run,”said Oberlin Reyes, a student in Virginia. “It’s hard to go up the stairs with my backpack,because it’s too heavy,”
Oberlin was among students whose backpacks were weighed for a week in a recent study.
They had regular backpacks with two straps(带子)to carry them, but a number of students with heavy loads had switched to rolling backpacks (which have wheels and can roll on the ground).
Shirley Park, whose backpack weighed 10 kilograms,said she changed to a rolling backpack because she was starting to have back  pain.
How much is too much?Experts say students should carry no more than 10 to 15 percent of their own body weight.
A few students had one suggestion to lighten the load:less homework.
P.S.( 附)Doctor’s suggestion:
1 Lighten the load. Clean out binders(活页材料)and take home only the books you need that night.
2 Wide straps are better. They send out the weight over your shoulders more evenly(均匀)。 And be sure to wear both straps rather than hanging the pack over one shoulder.
3. Pack smart. The heavier things should be packed closed to the back.
4.Bend both knees when you pich up the pack ,and don’t just bend over  at the waist.(腰)
