Summer heat can be dangerous, and heat leads to tragedy far too often. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.
For Bishop Curry, a fifth grader from Mckinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch(草图) of a device he called “Oasis.”
The device would attach to carseats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the carseat, it would begin to circulate cool air. Curry also designs the device using GPS and Wi-Fi technology, which would alarm the child’s parents and, if there was no response from them, the police.
Curry’s father believes that the invention has potential. “The cool thing about Bishop’s thinking is none of this technology is new,” he said. “We feel like the way he’s thinking and combining all these technologies will get to production faster.” His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.
In January, Curry’s father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis’ potential that they have raised more than twice that--over $46,000.
Curry’s father remembers the first time he saw his son’s sketch. “I was so proud of him for thinking of a solution,” he said. “We always just complain about things and rarely offer solutions.”
1.What inspired Curry to invent Oasis?
A. His narrow escape from death after being locked in a car
B. His knowledge of many children’s death because of car heat
C. The death of his neighbor’s baby after being left in a hot car
D. The injury of 37 children in his school in a car accident
2.What would Oasis do if it was hot in a car with a child?
A. It would inform the parents or even the police
B. It would pump out the hot air in the car
C. It would sound the alarm attached to the car
D. It would get the window open to save the child
3.What does Curry’s father think is cool about Curry’s invention?
A. It used some of the most advanced technology
B. It simply combined technologies that existed
C. It could accelerate production of new technology
D. It is the most advanced among similar products
4.Why did Curry’s father start a campaign to raise money?
A. To conduct experiments to test the invention
B. To get other children devoted to inventions
C. To support a charity of medical aid for children
D. To get the patent and bring it to production

高二英语单项填空中等难度题查看答案及解析
In some places around the world, summer heat can be cruel. But city planners in Dubai, a major city in the Middle Eastern country of the United Arab Emirates (UAE), have come up with their own solution to the summer temperatures, which there can increase to over 113 degrees Fahrenheit. Developers plan to build a 48-million-square-foot indoor building complex called the “Mall of the World”. The complex will be fully enclosed (封闭的) and completely climate-controlled.
This “indoor city” helps to draw visitors to the UAE even during the hot summer months. Sheikh Mohammed bin Rashid A1 Maktoum, the vice president of the UAE, explains, “Tourism is a key driver of economy, and we aim to make the UAE an attractive destination all year long.” Visitors will have access to the indoor city’s hotels, health-care centers, shops, entertainment, and more than 4 miles of enclosed streets. In addition, the developers plan to build the world’s largest indoor theme park. A retractable glass roof will cover the park. The roof will open up in the winter months, when the weather is cooler.
Plans for the mall also include a cultural center, with sections modeled on other cities around the globe. These include a theater district modeled on New York’s Broadway, a shopping area which is like the popular Oxford Street in London, and a walkway that echoes (模仿) Barcelona’s busy street La Rambla.
Some people worry about the large amount of energy it will take to keep the building cool. Fossil fuels, such as coal, oil, or natural gas, are burnt to produce the electricity needed for air-conditioning. In addition, building the mall of the world won’t be cheap. It is estimated (估计) that the development will cost more than $6.8 billion over the next 10 years. But this isn’t Dubai’s first over-the-top building. It has the tallest building in the world, the biggest flower garden in the world, one of the largest aquariums on the planet, and a human-made island in the shape of a palm tree.
1.What is the purpose of building the “indoor city”?
A. To help develop the tourism.
B. To make local people feel cool.
C. To create a new form of economy.
D. To control the outside temperature.
2.What does the underlined word “retractable” in Paragraph 2 mean?
A. Being able to be recycled.
B. Being attractive to someone.
C. Being too hard to be broken.
D. Being able to be moved backwards.
3.According to the passage, which of the followings is true about the cultural center？
A. It helps people to understand culture shock.
B. It shows people the development of Dubai.
C. It provides chances for people to exchange views.
D. It makes people experience lives of different countries.
4.What may be the result of building the Mall of the World?
A. There will be no materials to be used soon.
B. The building will not be as cool as expected.
C. The environment will be damaged to some degree.
D. Dubai will become a poor country due to the high costs.

Nuclear power's(核能的) danger to health, safety, and even life itself can be described in one word: radiation(辐射).
Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being outright by killing masses of cells (细胞) in important organs (器官). But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
1.According to the passage, the danger of nuclear power lies in ________.
A. nuclear mystery B. radiation detection
C. radiation level D. nuclear radiation
2.Radiation can lead to serious results even at the lowest level ________.
A. when it kills few cells
B. if it damages few cells
C. though the damaged cells can repair themselves
D. unless the damaged cells can reproduce themselves
3.Radiation can hurt us in the way that it can ________.
A. kill large numbers of cells in main organs so as to cause death immediately
B. damage cells which may grow into cancer years later
C. affect the healthy growth of our younger generation
D. lead to all of the above results
4.Which of the following can be best inferred from the passage?
A. The importance of protection from radiation cannot be overemphasized (过分强调).
B. The mystery about radiation remains unsolved.
C. Cancer is mainly caused by radiation.
D. Radiation can hurt those who do not know about its danger.

Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately, your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred.

高二英语单项填空简单题查看答案及解析
Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help.
First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling (肿大) and pain may occur. Unless the burn involves large portions of the body, it can be treated at home.
Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters (水泡) develop. Severe pain and swelling also occur. Second-degree burns require medical treatment.
Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention.
Follow these steps when treating minor burns at home:
1) If the skin is not broken, run cool water over the burn for several minutes.
2) Cover the burn with a sterile (消过毒的) bandage or clean cloth.
3) Take aspirin to relieve any swelling or pain.
Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps:
1) Remove the person from the source of the burn (fire, electrical current, etc.).
2) If the person is not breathing, begin mouth-to-mouth resuscitation (人工呼吸) immediately.
3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it.
4) Cover the burned area with a cool, moist, sterile bandage or clean cloth. Do not place any creams, ointments (药膏) or ice on the burned area or break blisters.
5) Monitor the patient for signs of shock, and treat accordingly.
1. The underlined sentence in the first paragraph probably means “______”.
A. They can be dangerous if you don’t treat them seriously
Ｂ. They range from slight burns to deadly ones
C. They seldom cause deaths even if not treated properly
D. They usually cause deaths if not treated properly
2. Burns are divided into different degrees according to _______.
A. what kind of treatment they need
B. what kind of tissue of the body is damaged
C. whether there is pain and what degree of pain there is
D. which layer of skin is burned
3. From the passage we learn that _______.
A. if there is severe pain, then you need medical treatment
B. first-degree burns don’t require medical treatment
C. burns without pains can be treated at home
D. the larger the swelling is, the more serious it is
4. It can be inferred from the passage that ______.
A. you shouldn’t cover the burn with a bandage or cloth if it is severe
B. you shouldn’t move the person unless you know how to do first aid
C. you shouldn’t run cool water over the burn if the skin is broken
D. you shouldn’t place any wet towels on the burned area
