2023年青?？佳杏⒄Z考試考前沖刺卷 本卷共分為1大題50小題，作答時間為180分鐘，總分100分，60分及格。 一、單項選擇題（共50題，每題2分。每題的備選項中，只有一個最符合題意） 1.Text 2 There is nothing like the joy of finding out that something sinful is actually good for you, whether it’s sex, chocolate or a glass of fine zed wine--or, for that matter, beer, whisky or a satisfying aperitif. We’ve long heard exciting hints that red wine has unique benefits for the heart. But the same sunny reputation for heart health is now starting to shine on all liquor. No matter where you look, the dominant alcoholic beverage is beneficial--whether it’s red wine in France and Italy, sake in Japan or beer in Germany, says Dr. Walter Willett, chair of nutrition at the Harvard School of Public Health. This has led researchers to an inescapable conclusion. As healthful as components of red wine may be, the primary benefit must come from ethanol itself. In short, it’s the alcohol, stupid. But don’t go overboard. Protection comes only with light to moderate intake--two drinks a day for men or a miserly one a day for women. The major benefit of alcohol seems to come from its ability to boost levels of HDL, the good cholesterol that helps keep arteries clear of plaque. Ethanol does that by signaling the liver to make more of a substance called Apo Al, the major protein in HDL. The effects can be striking. Depending on the individual, you can get increases of 10 to 30 percent in HDL in a week, says Harvard epidemiologist Eric Rimm. Alcohol also makes blood less sticky and less likely to form clots that cause heart attacks and strokes. It also appears to have mild anti-inflammatory effects. And it enhances insulin sensitivity--which may explain why moderate alcohol consumption correlates with a lower incidence of type 2 diabetes. But alcohol is a dietary Jekyll and Hyde. Heavy intake can raise blood pressure, increase irregular heartbeat, and lead to heart failure. The most sobering news concerns cancer. A recent analysis of 156 studies found that as alcohol intake increases, so do risks of tumors in the mouth, and liver. Even moderate drinking can boost breast-cancer risk a small amount. Is moderate drinking worth the risks For some people--pregnant women, people with liver disease or a history of alcoholism--the answer is no. But for most of us, the benefits will probably outweigh the hazards. Whether you sip wine, beer or spirits, your heart may thank you.By using the word "correlates" (Line 7, Paragraph 3 ), the author implies that（） A．drinking alcohol might cause diabetes. B．both types of diabetes are related to alcohol consumption. C．drinking alcohol is good for people with diabetes. D．drinking alcohol might lower the risk of diabetes. 2.Text 2 There is nothing like the joy of finding out that something sinful is actually good for you, whether it’s sex, chocolate or a glass of fine zed wine--or, for that matter, beer, whisky or a satisfying aperitif.

D．a(chǎn)ny alcohol. 3.Text 3 Is sitting in traffic as inevitable as death and taxes Perhaps not. Many countries now have dedicated traffic-monitoring centres linked to networks of cameras and sensors. Throw in traffic-spotting aircraft, accident reports and the known positions of buses fitted with satellite-positioning gear, and it is possible to see exactly what is happening on the roads. Drivers could switch from busy to quiet routes and avoid congestion-if only they had access to this information. And now they do. Systems such as the Traffic Message Channel and the Vehicle Information and Communication System (VICS), in Europe and Japan respectively, pipe. data from traffic centres into in-car navigation systems via FM radio signals. Drivers can see where the traffic is and try to avoid it. Honda, a Japanese carmaker, even combines VICS data with position data from 150,000 vehicles belonging to members of its Premium Club so that they can choose the fastest lane on a congested road, says David Schrier of ABI Research, a consultancy. Meanwhile ITIS, a British company, is one of several firms experimenting with mobile-phone signals to monitor traffic on roads that lack sensors or cameras. Its software hooks into a mobile operator’s network and uses a statistical approach to deduce traffic speeds as phones are handed off from one cell tower to another. The data must be cleaned up to exclude pedestrians and cyclists, but this idea has great potential, says Mr Schrier. Another way to dodge traffic is to predict where and when it will form. In Redmond, Washing ton, at the headquarters of Microsoft, employees have been testing a traffic-prediction system called JamBayes. Users register their route preferences and then receive alerts, by e-mail or text message, warning them of impending traffic jam. JamBayes uses a technique called Bayesian modeling to combine real-time traffic data with historical trends, weather information and a list of calendar events such as holidays. Eric Horvitz of Microsoft, who developed the system, says it is accurate 75% of the time, and 3, 000 employees use it daily. A system called Beat-the-Traffic, developed by Triangle Software of Campbell, California, with funding from the National Science Foundation, goes further. It not only warns drivers of impending traffic but also suggests an alternative route via e-mail or text message. Andre Gueziec, the firm’s boss, thinks traffic forecasts will become as prevalent as weather forecasts. Indeed, in June, KXTV News 10, a TV station in Sacramento, California, began showing Triangle’s traffic forecasts for the coming week.It can be inferred from the passage that（） A．Traffic jam remains unavoidable worldwide. B．Traffic forecasts will become as authoritative as the weather forecasts. C．There is always a short cut by using one of these systems. D．New systems will improve the transportation situation. 4.Text 3 Is sitting in traffic as inevitable as death and taxes Perhaps not.

It began, as far as the Centers for Disease Control (CDC) can tell, in Norwalk, U. S., in October 1968, when 116 eleme
