1、学习好资料英语四级真题及答案Section BDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice. The Gatais used to frown when they received power bills th
2、at routinely topped $200. Last September the couple moved into a 1,500-square-foot home in Premier Gardens, a subdivision of 95 zero-energy homes(ZEH)just outside town. Now theyre actually eager to see their electricity bills. The grand total over the 10 months theyve lived in the three-bedroom hous
3、e: $ 75. For the past two months they havent paid a cent. ZEH communities are the leading edge of technologies that might someday create houses that produce as much energy as they consume. Premier Gardens is one of a half-dozen subdivisions in California where every home cuts power consumption by 50
4、% , mostly by using low-power appliances and solar panels. Aside from the panels on the roof, Premier Gardens looks like a community of conventional homes. But inside, special windows cut power bills by blocking solar heat in summer and retaining indoor warmth in winter. The rest of the energy savin
5、gs comes from the solar units. They dont just feed the home they serve. If they generate more power than the home is using, the excess flows into the utilitys power grid(电网). The residents are billed by net metering : they pay for the amount of power they tap off the grid, less the kilowatts(千瓦)they
6、 feed into it. If a home generates more power than it uses, the bill is zero. That sounds like a bad deal for the power company, but its not. Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner. It helps us lower usage at peak power
7、 times, says solar expert Mike Keesee. That lets us avoid building costly plants or buying expensive power at peak usage time. Whats not to like? Mostly the costs. The special features can add $ 25,000 or more to the purchase price of a house. Tax breaks bring the cost down, especially in California
8、, but in many states ZEHs can be prohibitively expensive. For the consumer, its a matter of paying now for the hardware to save later on the utilities. 58 Why are the Gatais eager to see their electricity bills now? AThey want to see how much they have saved. BThey want to cut down their utility exp
9、enses. CThey want to know if they are able to pay. DThey want to avoid being overcharged. 59 What is special about the ZEH communities? AThey have created cutting-edge technologies. BThey aim to be self-sufficient in power supply. CThey are subdivided into half a dozen sections. DThey are built in h
10、armony with the environment. 60 How are the residents in the ZEH communities billed for electricity use? AThey are only charged for the amount of power they consume on rainy days. BThey neednt pay a single cent for their power consumption on sunny days. CThey only pay for the excess power that flows
11、 into the utilitys power grid. DThey pay for the electricity from the grid less their home-generated power. 61 What does the net metering practice mean to the power company? AMore pressure at peak time. BLess profits in the short term. CIncreased electricity output. DReduced operational costs. 62 Th
12、e author believes that buying a house in a ZEH community_. Ais but a dream for average consumers Bgives the owner substantial tax benefits Cis a worthy investment in the long run Dcontributes to environmental protection Romantic love has clear evolutionary roots but our views about what makes an ide
13、al romantic relationship can be swayed by the society we live in. So says psychologist Maureen OSullivan from the University of San Francisco. She suggests that humans have always tried to strengthen the pair-bond to maximise(使最大化)reproductive success. Many societies throughout history and around th
14、e world today have cultivated strong pressures to stay married. In those where ties to family and community are strong, lifelong marriages can be promoted by practices such as the cultural prohibition of divorce and arranged marriages that are seen as a contract between two families, not just two in
15、dividuals. In modern western societies, however, the focus on individuality and independence means that people are less concerned about conforming to(遵守)the dictates of family and culture. In the absence of societal pressures to maintain pair-bonds, OSullivan suggests that romantic love has increasi
16、ngly come to be seen as the factor that should determine who we stay with and for how long. Thats why historically we see an increase in romantic love as a basis for forming long-term relationships, she says. According to OSullivan culture also shapes the sorts of feelings we expect to have, and act
17、ually do experience, when in love. Although the negative emotions associated with romantic lovefear of loss, disappointment and jealousyare fairly consistent across cultures, the positive feelings can vary. If you ask Japanese students to list the positive attributes they expect in a romantic partne
18、r, they rate highly things like loyalty, commitment and devotion, says OSullivan. If you ask American college women, they expect everything under the sun: in addition to being committed, partners have to be amusing, funny and a friend. We judge a potential partner according to our specific cultural
19、expectations about what romantic love should feel like. If you believe that you have found true romance, and your culture tells you that this is what a long-term relationship should be based on, there is less need to rely on social or family pressures to keep couples together, OSullivan argues. 63 W
20、hat does the author say about peoples views of an ideal romantic relationship? AThey vary from culture to culture. BThey ensure the reproductive success. CThey reflect the evolutionary process. DThey are influenced by psychologists. 64 We can infer from the passage that strong family and community t
21、ies_. Alargely rely on marriage contracts Bcan contribute to stable marriages Coften run counter to romantic love Dmake divorces virtually unacceptable 65 Without social pressures to keep pair-bonds, romantic love_. Awill be a substitute for marriage in human relationships Bplays a key role in maint

Athey expect different things from their partner Bthey tend to exaggerate each o
