问题 选择题

下图为我国某地利用新能源的路灯,据此完成下列问题。

小题1:这种路灯所利用的两种能源的共同点有

①都属于非可再生能源 ②能源丰富区分布一致 

③都属于清洁能源 ④都属于来自太阳辐射的能源

A.①②

B.②③

C.③④

D.①④小题2:为了提高新能源的利用效率,科研人员对新能源路灯进行了技术改造,使太阳能蓄电池板在水平和垂直方向可以转动。下列做法正确的是

A.从春分到秋分,太阳能蓄电池板与地面的倾角不断变小

B.从夏至到冬至,太阳能蓄电池板与地面的倾角不断变小

C.夏至日附近,太阳能蓄电池板一天内水平旋转的角度较小

D.冬至日附近,太阳能蓄电池板一天内水平旋转的角度较小

答案

小题1:C

小题2:D

题目分析:

小题1:该路灯使用的能源是太阳能和风能,两种能源都属于可再生能源;两种能源丰富区分布不一定一至,如撒哈拉沙漠,太阳能资源丰富,而风能资源不丰富;而两种能源都属于无污染的清洁能源;都最终属于来自太阳辐射的能源。故选C。

小题2:当太阳能的蓄电池板与太阳辐射垂直时,所获得的太阳能最多。在北回归线以北地区,从春分到夏至,太阳高度不断增大,太阳能蓄电池板与地面的倾角不断变小,而从夏至到秋分,太阳高度不断增小,太阳能蓄电池板与地面的倾角不断变大;从夏至到冬至,我国大部分地区太阳高度不断增小,太阳能蓄电池板与地面的倾角不断变大;夏至日附近,我国一天中太阳高度变化大,所以太阳能蓄电池板一天内水平旋转的角度较大;而冬至日附近,我国一天中太阳高度变化小,所以太阳能蓄电池板一天内水平旋转的角度较小。故选D。

Timberwolves are Marching to a New Tune

森林狼按新的节拍在前进

For the past seven years,Kevin McHale has struggled to put the right combination around his superstar,Kevin Garnett.McHale brought in dozens of players to complement his main man,but in the end the Timberwolves always looked like the’70s band Wings-one star(Paul McCartney) and a bunch of people nobody noticed.

With apologies to all of you who still are jamming to"Silly Love Songs,"Wings never could live up to the Beatles.They didn’t have the star power.

Well,McHale finally has found his own personal John Lennon and Ringo Starr,and their names are Sam Cassell and Latrell Sprewell.The two veteran guards have given the Wolves an edge they’ve never had before,and suddenly Garnett doesn’t have to do it all by himself. Wednesday in San Antonio,Garneu struggled at the start,found himself in foul trouble and never really got into the flow of the game.As all superstars do,he still managed to put up good numbers(22 points and 10 rebounds).But Gamett never found his groove.and he certainlv didn’t control the game.

Fortunately for Kevin Garnett,he didn’t have to.Cassell,who has hit more big shots than anyone this side of Reggie Miller,came through with a huge game.Displaying his uncanny knack for creating his own midrange shots,Cassell riddled the Spurs’defense for 33 points including several clutch buckets in the fourth quarter.

Some guys like to take big shots.Cassell needs them.When the game gets tight and his.team needs a basket,Sam’s eyes light up and he enters another world.He lusts for moments like those. Sprewell also had a major impact in Wednesday’s victory,scoring 24 points and sealing the win with a steal and a highlight-reel slam.He is playing with amazing energy and zeal,and a touch of attitude that we haven’t seen from Wolves players in the past.Together.the"Big Three" have become a major force that has to rank with any combination in the league.

Wednesday’s victory in San Antonio epitomized the type of team that Minnesota has been all season.The Wolves defended well,scored 100 points against the league’s best defense.got major contributions from their bench and huge shots from their stars,and showed a resilience and confidence usually reserved for championship teams.

After several first-round flameouts,is this the year the Wolves finally make it over the hump in the playoffsIt’s only January,so we probably shouldn’t get ahead of ourselves.But the team I saw Wednesday night showed all the signs of being a major player in the NBA playoffs this spring.

If things fall just right for McHale,maybe he can finally stop fiddling with his roster and simply"Let It Be.\
