问题     Bilingual education is controversial in the United States.【C1】______, a growing body of research shows that【C2】______speaking two languages comes with certain types of improved mental【C3】______. Being able to use two languages and never knowing which one to be used right now is good to the brain. The attentional executive system, crucial for all higher thought, seems to be【C4】______.
    Executive functioning allows us to keep a goal in mind, take【C5】______to achieve that goal, and to ignore other information that might【C6】______ us from that goal. The question is; Would it be the case that bilinguals, by the【C7】______need for controlling the two languages, develop a more efficient executive functioning system? The results suggest that bilinguals【C8】______have this positive collateral effect, which is even stronger when it goes to kids and older people. These are ages【C9】______executive functioning is worse.
    Bilinguals do better at tests that require multitasking, including ones that【C10】______ driving and talking on a phone. And the longer people have spoken multiple languages, the greater the cognitive【C11】______. There are even benefits when languages were【C12】______at later ages.
    Certainly, bilingualism comes with some 【C13】______. Bilinguals have more " tip-of-the-tongue" problems. There are a couple of milliseconds before they can target. Bilingual children, also, have 【C14】______ a smaller vocabulary in each of their languages than monolingual children,【C15】______they probably know more words altogether.
    Still, all of these findings are【C16】______ abstract. It is difficult to take laboratory findings showing better executive functioning in bilinguals and demonstrate that they【C17】______ into better performance in the workplace or some other practical 【C18】______. The only real, world application preliminarily demonstrated may be that multilingualism can【C19】______health benefits to Alzheimer’s patients. Bilinguals show【C20】______ of the disease up to four years later than monolinguals.
【C10】
选项 A、simulated
B、controlled
C、pretended
D、performed
答案A
解析 动词辨析题。句意为：双语者在多重任务测试中表现得更好，这些测试包括模拟边打电话边开车的情境。根据原文，这里所说的是一种测试，所以必然不是真的边开车边打电话，而是一种模拟测试，因此simulated为答案。controlled“受控”和performed“表演”不符合语境，排除；pretended“假装”有一定干扰性，但该词不适用于科学研究，排除。
