陕西省咸阳市2024届高三下学期高考模拟(三)英语试卷(音频暂未更新)

 阅读下列短文. 从每题所给的 A、B、C 和 D 四个选项中. 选出最佳选项。

Spending all day glued to your smartphone probably isn't doing you any favors. Too much phone use has been linked with a range of concems, including sleep issues, joint pain and even relationship problems. But if it's radiation you're worried about, experts say you don't have to ditch your phone. 

"There's no risk of anything hazardous or dangerous with radiation from cellphones, "said Gayle Woloschak, an associate dean and professor of radiology at the Northwesterm Univerity Feinberg School of Medicine. As with all cellphones, along with Wi-Fi networks, radio stations, remote controls and GPS, smartphones do send out radiation, said Emily Caffrey, an assistant professor of health physics at the University of Alabama at Birningham. They use invisible energy waves to transmit voices, texts, photos and emails to nearby cell towers, which can carry them to almost anywhere in the world. But nearly three decades of scientific research has not linked such exposures to medical issues like cancer, health authorities including the Food and Drug Administration say. Here's what we know. 

"Radiation"describes many types of energy, some of which do carry risks, explained Dr. Howard Fine, director of the Brain Tumor Center at NewYork —Presbyterian Weill Cornell Medical Center in New York City, "It is often sent out from radioactive substances", Atomic bombs, or, to a far lesser degree, X-ray machines, send out energy called ionizing radiation that in high enough or frequent enough amount can damage DNA and cause cancer, Dr. Fine said. 

But smartphone energy falls into a category called non-ionizing radiation, Dr. Caffrey said, which isn't powerful enough to cause this damage. "A lot of people think‘radiation is radiation, 'but it's not all the same, "Dr. Woloschak said. "There's no DNA damage seen from cellphone use. "

Most experts and health authorities like the F. D. A. and World Health Organization agree that there's no evidence that smartphone radiation causes health problems. Still, several studies over the years have made headlines for suggesting their links to brain diseases. Many of these studies have since been proved to be false, Dr. Fine said, including those focused on fifth-generation. 

(1)、What does the underlined word"ditch"in Paragraph 1 mean?
A、Make use of B、Keep track of. C、Get hold of D、Get rid of.
(2)、Which statement best reflects the attitude of health authorities towards cellphone radiation?
A、They consider it secure based on current research. B、They are indifferent due to lack of sufficient data C、They express concern and require strict regulations. D、They are doubtful and appeal for immediate action.
(3)、What does this text mainly tell us?
A、Forming a healthy lifestyle is vital. B、Smartphones need radiation limits. C、Radiation concerns are unfounded. D、Technology reduces radiation risks.
(4)、Where would this text most likely appear?
A、In a science magazine. B、In a collection of short stories. C、In a school newsletter. D、In a phone advertising brochure.

There is a growing number of kidults—or adults who wear themask of maturity but prefer to pander(迎合) to their inner child.

    They feel ill equipped for parenthood, because they don't see what values or lessons they could honestly pass on to their young, besides self-centeredness and a passion for the good things in life. They are trying to live by not acting their age.

    As Ms Jane put it in her letter: I'm married, in my late 20s and enjoy a lifestyle other married graduate couples enjoy: winning and dining, tasteful clothes, travel and a career. Why give up all these for a baby?

    It is reported that when asked whether they were adults, most people in their 20s answered they were not sure. This reflected a global economy in which people chased more papers to get better jobs that would comfortably support middle class living.

    Being a kidult is not all about being selfish, though. With the untold uncertainties of war, fluctuating(波动) markets, disease and terrorism, many see this world as a poor place to live in—let alone bring kids up in. This seems especially so in urban living. All anyone wants after a long, hard day at work is some peace and quiet.

    My classmate, Jenny, mused(沉思) recently howour friends living in small Malaysian towns were onto their second or third kids. Maybe they just loved having children around. Or maybe, in their own way, they wanted to leave the world a better place than they found it.

    That's how you, I and everyone know we have the chance tobreathe air, touch grass and see sky. I think out parents understand that just being alive is an experience worth passing on.

    How many times have you come back and felt terribly tired, feeling like your head is going to explode? Sounds familiar, right? Well, there are several ways to reduce the frequency of headaches, and those are: eating balanced diet through the day, making sure your body is well hydrated (保持身体水分);getting some exercise to remove the negative energy, like helping yourself with a short massage (按摩)on your head. However, preparing an easy recipe will instantly put a smile on your face after your workday.

    You will need these simple ingredients (配料)to prepare the magical drink which will stop your headache: Lemon juice; 2 teaspoons of salt (preferably high quality salt); 1 cup of water.

    Directions:

    Squeeze 2 lemons. Pour the lemon juice into a cup and add 2 teaspoons of salt. Mix the two ingredients. Add a cup of water to the content. Drink the mixture quickly.

    How will this drink work and what are the benefits of its ingredients?

    Salt: Here is what salt does for your body: regulates your blood sugar, balances the sugar levels; benefits nerve cells for communication and information processing; obtains acidity from your body's cells, especially brain cells; works as a strong anti-stress element for the body; adds energy in your body's cells.

    Lemon Juice: This excellent juice, full of vitamin C and anti-poisons, will release all poisonous substances from your body and give you a sense of lightness.

At Englands University of Plymouth, Professor Eduardo Miranda has been programming pairs of robots to compose music. Miranda's robots have simple " vocal cords" (声带)and are programmed to sing and to listen to each other. The robots' unique warbling sounds (颤音) do not perfectly match the human voice, but each machine is exactly sharing music with the other in a new and unique way.

Each robot is equipped with speakers, software that mimics the human voice, a mouth that opens as it "sings," a microphone for ears, and a camera for eyes. The robots also move. Miranda hopes that by studying his robot vocalists, he can discover something about how and why humans create, perform, and listen to music.

When the robots sing, first one robot makes six random sounds. Its partner responds with more sounds. The first robot analyzes the sounds to see if their sequences (序列)) are similar. If they are, it nods its head and commits the sounds to memory, and the second robot notices and "memorizes" the musical sequence, too. If the first robot thinks the sounds are too different, it shakes its head and both robots ignore the sounds. Then the process continues.

Miranda set up an experiment in which he left the two robots alone in his study for two weeks. When he returned, his little warblers had, by imitating each other, not only shared notes but combined them. The product of their cooperation was far from symphonic, but the robots had begun to combine the notes into their own self-developed "songs".

With the help of his warbling robots, one of Miranda's goals is to create music that no human would ever compose. Miranda believes the robots are ideal for this purpose because they would not be influenced by any existing musical styles or rules.
