發(fā)布:2024/11/25 2:0:1組卷:1引用:2難度:0.92873.Humans really do have a sixth sense that lets us detect magnetic fields (磁場(chǎng)),but we're not aware we have it.It has long been known as ESP,Spider Sense,or the ability to see things before they happen.But now scientists have proved that humans really do have a sixth sense-that lets them detect magnetic fields.Tests have shown that mankind may have the same inborn sense of Earth's magnetic field that has long been proved to exist in animals.
By putting a protein from the human retina (視網(wǎng)膜) into fruit flies,researchers noticed that the insect adjusted its flight path just as if its eye had not been changed.This suggests that the "sixth sense" does exist in humans but we might not be aware of it.Animals use such sight to navigate long distances during migration or,in the case of birds,to "see" where they are going.The complex tests involved examining the process by which light goes through a bird's eye,which has interested the scientific community for more than 30 years.In the late 1970s,the physicist Klaus Schulten concluded that birds fly by relying on geomagnetically (地磁) sensitive biochemical reactions in their eyes.
Tests have shown that the special cells in the eye carry out this function using the protein cryptochrome (蛋白隱色素).Professor Reppert's team used wild fruit flies,replacing their version of cryptochrome with the human equivalent (等價(jià)物),and then put them in a maze (迷宮) with each wing wrapped in a metal coil (金屬圈).They then sent electricity through it so that the coil was magnetised in a way which is just like Earth's electromagnetic field (電磁場(chǎng)).The flies responded in exactly the same way as if they had their own cryptochrome,by either avoiding the magnetic fields or moving towards them if the researchers had placed sugar nearby.
The new study was published in the journal Nature Communications.
(1)What do we know about humans' sixth sense?
A.Humans have been aware of it since ancient times.
B.It is quite different from the animals'.
C.It is the ability to predict what will happen.
D.It is also a sense developed after birth.
(2)Why did researchers put a protein from the human retina into fruit flies?
A.To change fruit flies' flight path.
B.To test if humans have a sixth sense.
C.To examine the process of birds' flying.
D.To allow researchers detect magnetic fields.
(3)What does the underlined word "it" in Paragraph 3 refer to?
A.the maze
B.each wing
C.cryptochrome
D.the metal coil
(4)After being replaced the cryptochrome,how are the wild fruit flies?
A.They responded normally as if there had been nothing changed.
B.They couldn't avoid the magnetic fields like before.
C.They lost the sense of direction completely.
D.They couldn't find the sugar the researchers had placed nearby.發(fā)布:2024/11/25 0:30:3組卷:4引用:1難度:0.52874.The residents of Ashwaubenon,Wisconsin are no strangers to wild turkeys.However,Smoke,a turkey that has been living in the town since spring this year,is(1)

After John Henry was into the ICU,Nicole felt alone in the new state,although she knew that she had to leave her son's side in order to buy him some new clothes.Upon ordering an Uber ride to the nearby Rhea Lana children's clothing store,she was picked up by a woman named Belinda.
Shortly after Nicole got into Belinda's car,the new mother couldn't help talking about her heartbreaking circumstances.
"She told me her story," Belinda said. "She was in tears a couple of times and I really felt for her." Rather than simply dropping Nicole off at the store,however,Belinda parked the car and insisted on accompanying her passenger into the store so she could treat John Henry to new clothes.Needless to say,Nicole was filled with gratitude.
Nicole said, "For this stranger to go completely out of her way - stop what she was doing and stop making money- to come be with me for a couple of hours while we shopped together,that was just incredible." As Nicole cares for her newborn son and raises money for his medical conditions,she hopes to introduce the Uber driver to her son as a thank you for her compassionate gesture.
