21、ch blank from a list of choices given in a word bank following the passage.Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You
22、 may not use any of the words in the bank more than once.Many men and women have long bought into the idea that there are“male”and“female”brains,believing that explains just about every difference between the sexes.A new study 26 that belief, questioning whether brains really can be distinguished by
23、 gender.In the study, Tel Aviv University researchers 27 for sex differences throughout the entire human brainAnd what did they find? Not much. Rather than offer evidence for 28 brains as “male” or“female”,research shows that brains fall into a wide range , with most people falling right in the midd
24、le.Daphna Joel ,who led the study, said her research found that while there are some genderbased 29 ,many different types of brain cant always be distinguished by gender.While the “average”male and“average”female brains were 30different, you couldnt tell it by looking at individual brain scans. Only
25、 a small 31of people had “all-male”or“all-female”characteristics.Larry Cahill, an American neuroscientist（神经科学家） ，said the study is an important addition to a growing body of research questioning 32 beliefs about gender and brain function. But he cautioned against concluding from this study that all
26、 brains are the same, 33 of gender.“Theres a mountain of evidence 34 the importance of sex influences at all levels of brain function ,”he told The Seattle Times.If anything, he said, the study 35that gender plays a very important role in the brain“even when we are not clear exactly how.”A) abnormal

Answer the questions by marking the corresponding letter on Answer sheet 2.Can Burglars Jam Your wireless Security Sy
29、stem?A Any product that promises to protect your home deserves careful examination. So it isnt surprising that youll find plenty of strong opinion about the potential vulnerabilities of popular home-security systems.B The most likely type of burglary(入室盗窃) by far is the unsophisticated crime of oppo
30、rtunity, usually involving a broken or some forced entry. According to the FBI, crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2003. The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. T
31、he FBI doesnt even track those statistics.C One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar(入室盗窃）might be able to shut your system down simply by cutting the righ
32、t cable. With a wireless setup, you stick battery-powered sensor up around your home that keeps an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed,theyll transmit a wireless alert signal to aa base station that will then raise the alarm. Thatapproach
33、 will eliminate most cord-cutting concerns-but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, whats to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?D Jamming concerns are nothing new, and t
34、heyre not unique to security systems. Any deviceThats built to receive a wireless signal at a specific can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, lets say you wanted to “jam” a conversation between two people-all youd need to do is yell in the listeners
35、ear.E Security devices are required to list the frequencies they broadcast on-that means that a potential thief can find what they need to know with minimal Googling. They will, however, need to know what system they are looking for. If you have a sign in your yard declaring what setup you use, that
36、d point them in the right direction, thought at that point, we are talking about a highly targeted, semi-sophisticated attack, and not the sort of forced-entry attack that makes up the majority of burglaries. Its easier to find and acquire jamming equipment for some frequencies than it is for others
37、.F Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editors Choice distinction, utilizes a special system thats capable of separating incidental RF interference form targeted jamming attacks. When the system thinks its being ja
38、mmed, itll notify you via push alert （推送警报）. From there, its up to you to sound the alarm manually.G SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment .After taking appropriate measu
39、re to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it is possible with the right equipment. However, we also verified that SimpliSafes anti-jamming system words. It caught us in the act, sent an alert to my smartphone, and also lis
40、ted our RF interference on the systems event log. The team behind the article and video in question make no mention of the system, or whether or not it detected them.H We like the unique nature of that software. It means that a thief likely wouldnt be able to Google how the system words, then figure
41、 out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly form system to system, which means there wouldnt be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoi
42、nt addresses the issue in a blog on its site, citing their own jam protection software and claiming that there arent any documented cases of a successful jam attack since the company began offering wireless security sensors in the 1980s.I Jamming attacks are absolutely possible. As said before, with
43、 the right equipment and the right know-how, its possible to jam any wireless transmission. But how probable is it that someone will successfully jam theirway into your home and steal your stuff?J Lets imagine that you live in a small home with a wireless security setup that offers a functional anti
44、-jamming system. First, a thief is going to need to target your home, specifically.Then, hes going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while youre away,
45、so the thief will still need to break in. That means defeating the lock somehow, or breaking a window .Hell need to be jamming you at this point, as a broken window or opened door would normally release the alarm .So, too, would the motion detectors in your home, so the thief will need to continue j
46、amming once hes inside and searching for things to steal. However, hell need to do so without tripping the anti-jamming system, the details of which he almost certainly does not have access to.K At the end of the day, these kinds of systems are primarily designed to protect against the sort of oppor
47、tunistic smash-and-grab attack that makes up the majority of burglaries. Theyre also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exploit lighting at night. No system is impenetrable, and
48、none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessary equipment and skill.37. Interfering with a wireless security system is similar to interfering with a conversation.38. A burglar has to continuously jam the wireless s
