central say this proves the importance of conservation efforts in the ancient tropical forests of the region.Within the ancient tropical forests of a region known as Vietnam’s“Green Corridor,”scientists found a snake,five orchids 兰花,and two butterflies as well as three other plants new to science and exclusive 独有的 to the Annamites Mountain other plant species,including four orchids,are still under examination but also appear to be new species.“Discoveries of so many new species are rare and occur only in very special places like the Green Corridor,”said Dickinson,WWF’s chief conservation scientist in the Green Corridor.“Several large mammal species were discovered in the 1990s in the same forests so these latest discoveries may be just the tip of the iceberg.”The rainforests likely have existed as continuous undisturbed forest cover for thousands of years,and,as a result,offer unique habitats for many species,said WWF experts.The new snake species,called the white-lipped keelback,prefers living by streams where it catches frogs and other small can reach 31 inches.Three of the new orchid species are entirely leafless,which is unusual even among orchids,containing no chlorophyll 叶绿素 commonly found in other new plants include an aspidistra which produces a nearly black flower and a newly-discovered species of plant with beautiful yellow flowers.The two new butterfly species are among eight discovered in the province since is a skipper—a butterfly with quick,darting flight habits—from the genus Zela and the other is a new genus in the

larger vocabularies when they start school than those who don’t,US researchers said.They said babies with wealthier,better-educated parents will probably sign may help explain why some children from low-income families perform less well in school.“When children enter school,there is a large difference in their vocabularies,”said the University of Chicago’s Meredith Rowe,whose study appears in the journal Science.Gestures could help explain the difference,Rowe told the American Association for the Advancement of Science yearly meeting in Chicago.Vocabulary is an important predictor of school research showed that rich,educated parents tend to talk to their children more than poorer,less-educated ones.“What we are doing here is asking：Does this social-economic situation relate to gesturesCan that explain some of the difference we see at school entry 进入”Rowe said.The researchers filmed 50 Chicago-area children and parents from different economic backgrounds and counted the number of gestures,such as pointing at a picture.The team found that 14-month-olds from high-income,well-educated families used gestures to express about 24 different meanings during 90 from lower-income families expressed 13 meanings.When the same children entered school at age four and a half,those from higher-income families had better vocabulary scores on standardized tests.“At 14 months,an age when there aren’t even social-economic differences in their talk yet,we see there are differences in their gestures,”Rowe said.The videos found that parents from wealthier families gestured more with their children than the other parents.Rowe said the findings suggest that gestures can at least partly explain vocabulary differences between the groups,and may prove useful as the

leads to workers’ unhappiness and more sick-leave,a survey调查 showed on Wednesday.A survey carried out by of over 2,700 European office workers from the UK,France and Germany found that workplace dissatisfaction increased greatly with the age of computer equipment.“We do know that job satisfaction is falling in Britain and in most advanced nations,”said Stephen White,a researcher from the Work Foundation.“The actual reasons for this are the subject of very heated ’s certainly one interesting theory that technology may be the cause of this in some way,”White quarter of those using outdated computers in Britain said they were “quite”or“very dissatisfied”with their everyday job compared to 16 percent of those who had enjoyed an advantage from up-to-date technology.The survey also said that among workers dealing with outdated equipment,there was a 35 percent greater probability they would take six or more days of sick-leave per year compared with the average France,where more workers use older computers,the probability jumped to 55 percent.Results also showed that women in the three countries were more likely to be using outdated the UK,where more workers have up-to-date computers than in the other countries surveyed,the number of women using old equipment doubled that of men.White pointed out that there were two sides to this problem,saying that continually having to deal with new technology and new equipment can also be a source of worry.“Old and faulty equipment is a major cause of office dissatisfaction,there’s no question about it,but you also have to say that the frequent change of equipment is also,or could be,a main cause of dissatisfaction.”72．The underlined word “this”Paragraph 3 refers to ________.A．workplace dissatisfactionB．computer use in most jobsC．the aging of office computersD．the survey by73．How many office workers using old computers in Britain expressed their dissatisfactionA．16%.

2θ＝925.又π2<θ<π，∴cos θ＝－35. ∴tan θ＝sin θcos θ＝－43.(2)sin 2θ＋2sin θcos θ3sin 2θ＋cos 2θ＝tan 2θ＋2tan θ3tan

＝－sin(75°＋α)． ∵α为第三象限角，∴75°＋α为第三或第四象限角，又cos(75°＋α)＝13>0，∴75°＋α为第四象限角， ∴sin(75°＋α)＝－1－cos 275＝－1－⎝ ⎛⎭⎪⎫132＝－223，∴cos(105°－α)＋sin(α－105°)＝－13＋223＝22－13.(2)由已知得cos(θ－9π)＝－35，∴cos(π－θ)＝－35，∴cos θ＝35，∵π<θ<2π，∴3π2<θ<2π，∴sin θ＝－45，∴tan θ＝－43，∴tan(10π－θ)＝tan(－θ)＝－tan θ＝43.19．(12分)已知函数f(x)＝2cos(2x －π4)，x ∈R.(1)求函数f(x)的最小正周期和单调递增区间．(2)求函数f(x)在区间[－π8，π2]上的最小值和最大值，并求出取得最值时x 的值．解：(1)因为f(x)＝2cos(2x

－π4)在区间[－π8，π8]上为增函数，在区间[π8，π2]上为减函数，又f(－π8)＝0，f(π8)＝2，f(π2)＝2cos(π－π4)＝－2cos π4＝－1，所以函数f(x)在区间[－π8，π2]上的最大值为2，此时x ＝π8；最小值为－1，此时x ＝π2.20．(12分)函数f 1(x)＝Asin(ωx

＝Asin(2x ＋π6)，得A ＝2.故f 1(x)＝2sin(2x ＋π6)．(2)依题意，f 2(x)＝2sin[2(x －π4)＋π6]＝－2cos(2x ＋π6)，当2x ＋π6＝2k π＋π(k ∈Z)，即x ＝k π＋5π12(k ∈Z)时，y max ＝2.此时x 的取值为{x|x ＝k π＋5π12，k ∈Z}．21．(12分)已知函数f(x)＝2sin(2x ＋π6)－1.(1)若点P(1，－3)在角α的终边上，求f(α2－π12)的值；(2)若x ∈[－π6，π3]，求f(x)的值域．解：(1)因为点P(1，－3)在角α的终边上，所以sin α＝－32，cos α＝12，所以f(α2－π12)＝2sin[2×(α2－π12)＋π6]－1＝2sin α－1＝2×(－32)－1＝－3－1.(2)令t ＝2x ＋π6，因为x ∈[－π6，π3]，所以－π6≤2x ＋π6≤5π6，而y ＝sint 在[－π6，π2]上单调递增，在[π2，5π6]上单调递减， 且sin(－π6)＝－12，sin 5π6＝12，所以函数y ＝sint 在[－π6，5π6]上的最大值为1，最小值为－12，即－12≤sin(2x ＋π6)≤1，所以f(x)的值域是[－2,1]．22．(12分)已知函数f(x)＝Asin(ωx ＋φ)＋B(A>0，ω>0)的一系列对应值如下表：(1)根据表格提供的数据求函数f(x)的一个解析式；(2)根据(1)的结果，若函数y ＝f(kx)(k>0)的最小正周期为2π3，当x ∈[0，π3]时，方程f(kx)＝m 恰有两个不同的解，求实数m 的取值范围．解：(1)设f(x)的最小正周期为T ， 得T ＝11π6－(－π6)＝2π，由T ＝2πω，得ω＝1.又⎩⎨⎧B ＋A ＝3，B －A ＝－1.解得⎩⎨⎧A ＝2，B ＝1.令ω·5π6＋φ＝π2，即5π6＋φ＝π2，解得φ＝－π3，∴f(x)＝2sin(x －π3)＋1.(2)∵函数y ＝f(kx)＝2sin(kx －π3)＋1的最小正周期为2π3，又k>0，∴k ＝3，令t ＝3x －π3，∵x ∈[0，π3]，∴t ∈[－π3，2π3]，若sint ＝s 在[－π3，2π3]上有两个不同的解，则s ∈[32，1)，∴方程f(kx)＝m 在x ∈[0，π3]时恰好有两个不同的解，则m ∈[3＋1,3)，即实数m的取值范围是[3＋1,3)．。
