19、y first year living in Los Angeles, I was a birthday-party clown. I struggled a lot with my identity because, though I viewed myself as a filmmaker, everyone in my life viewed me as this ridiculous day job.Once I was told, “Tomorrow youre going to be Batman.” Now, keep in mind that at the time I had
20、 a giant mustache. I know a clown with a mustache is a huge red flag for parents. But I hadnt wanted to alter my physical appearance for that job, because that would have been me subconsciously admitting I was more of a clown than an artist.The next day, I went to the party in a huge public park, an
21、d I left my car parked far enough away so that the kids couldnt see Batman pulling up in a PT Cruiser. Walking to the party, I started to regret my choice not to shave. “Gosh, this party is not going to go well.” Sure enough, once I got close enough for them to actually start making out the features
22、 of my face, the entire party broke out in laughter. I was so embarrassed that I wanted to turn around and run back to my Batmobile. But then the laughter kind of changed into cheering and applause. Feeling kind of warm and fuzzy inside, I wondered, “Is this what encouragement and support feel like?
23、 Its so new.”Then I decided to make an entrance for these kids. I was still about 20 yards away from the party when I started running. My cape was billowing in the wind, and mustache or not, in that moment, I was Batman. I ran into the party, and the kids were all high-fiving me. The dad was saying,
24、 “I told you, son. I told you Batman has a mustache.” Then he took me over to this huge birthday cake with a frosting Batman drawn on it, and the Batman has a mustache. I just stared at it in disbelief and learnt that instead of just admitting that the cake was messed up, the parents said, “Batman h
25、as a mustache. He just shaves it for his movies.”That year, I struggled a lot with my identity; was I a filmmaker, or was I a clown? But that day, at least, there was no doubt in my mind what I was. I may not have been the hero that they ordered, and I certainly was not the hero they expected. But t

Americans spe
28、nd more than $1 billion a year on calcium supplements in hopes of delaying osteoporosis, a kind of bone disease that disables many elderly women and some men. Yet recent studies link calcium supplements to a higher risk of heart attacks. Last month, the U.S. Preventive Services Task Force issued a d
29、raft recommendation against taking calcium and vitamin D，saying there wasnt enough evidence of benefit to justify the risk.For generations of Americans who grew up encouraged to drink milk to maintain strong bones, the reports raised troubling questions: Is calcium not so important after all? Are th
30、e supplements unsafe? And how much is too much? “Its gotten very confusing but it doesnt need to be,” says Ethel Siris, director of the Toni Stabile Osteoporosis Center in New York. How much calcium people need varies by age and gender. “Adults generally need 1,000 mg daily, rising to 1,200 mg for w
31、omen over 50 and men over 70, according to guidelines issued in 2010. Children need 1,300 mg daily during the peak growing years of 9 to 18.”People also need sufficient levels of vitamin D to absorb the calcium. The IOM recommends 600 international units a day for most adults, and 800 daily after ag
32、e 70，although many physicians recommend more. It is difficult to take in that much vitamin D from food sources, so experts say many people should take vitamin D in supplement form.Getting adequate calcium from food is easier. For example, 8 ounces of milk or 6 ounces of yogurt has 300 mg of calcium,
33、 and one cup of spinach has 270 mg.But studies linking calcium supplements to heart attack have made experts more cautious of excess calcium than before. A study of 24,000 Germans published in the journal Heart last month, found that those who got their calcium exclusively from supplements were more
34、 than twice as likely to have a heart attack as those who took no supplements.Exactly how calcium supplements might contribute to heart attacks baffles experts. “Nobody has associated the calcium in your bloodstream with calcification(钙化)in your arteries(动脉),” says Nieca Goldberg, medical director o
35、f the Joan H. Tisch Center. Still, she says she now urges patients get their recommended calcium from food rather than from supplements to avoid possible problems.Osteoporosis experts also urge patients not to take more than the recommended amount of calcium. “People should definitely stop taking tw
36、o big calcium supplements a day,” says Dr. Dawson-Hughes. Even if the risks remain unclear, taking more than the body can absorb doesnt benefit bones,” so its not worth any risk.” She adds.27According to the new studies, what might be the result of taking much calcium?ADelaying aging.BBuilding muscl

With all the global challenges of today, we need revolutionary technology to help the world cope.There are different types of neurotechsome is invasive, some isnt. Invasive brain-co
40、mputer interfaces involve placing microelectrodes or other kinds of neurotech materials directly onto the brain or even embedding them into the neural tissue. Such technology has already improved the quality of life and abilities of people with different illnesses or impairments, from epilepsy to Pa
41、rkinsons Disease to chronic pain. There is also noninvasiveneurotech that can be used for similar applications. For example, researchers have developed wearables to infer a persons intended speech or movement. These are already quite impressive, but there is also neurotech that really pushes the env
42、elope. Not only can it sense or read neurodata but it can also modulateinvasively and noninvasively. This research is still in early stages, but its advancing rapidly.As neurotech becomes more commonplace, we must consider the risks it might present, the morals around it, and the necessary regulatio
43、n. We have to anticipate and deal with the implications related to the development and use of this technology. Any neurotech applications should consider potential consequences for the autonomy, privacy, responsibility, consent, integrity and dignity of a person.What if someone were to face employme
44、nt discrimination because the algorithms（算法） that power a neurotech application used for hiring misinterpret his or her neurodata? What if a criminal gets a hold of the previous or current neurodata of the secretary of defense and steals top secret information? Concerns increase when we are not just
45、 monitoring someones neurodata but also interpreting it, decoding the persons thoughtswith implications for accuracy and mental privacy.One tricky aspect is that most of the neurodata generated by the nervous systems is unconscious. It means it is very possible to unknowingly or unintentionally prov
46、ide neurotech with information that one otherwise wouldnt. So, in some applications of neurotech, the presumption of privacy within ones own mind may simply no longer be a certainty.As new, emerging technology, neurotech challenges corporations, researchers and individuals to reaffirm our commitment
47、 to responsible innovation, its essential to enforce guardrails so that they lead to beneficial long-term outcomeson company, national and international levels. We need to ensure that researchers and manufacturers of neurotech as well as policymakers and consumers approach it responsibly. Lets act now to avoid any future risks as neurotech maturesfor the benefit of humanity.31The first two paragraphs mainly _.Astate the quality of neurotechBstress the necessity of neurotechCcompare the functions of neurotechDpresent the technology of neurotech32What can be inferred from the passage?AN
