(3)北京的白晝時間比泉州更 (長或短)。(提示:晝長=日落時刻-日出時刻)。

(4)夏至日后,泉州的白晝時間將變 (長或短),日落時間將 (推遲或提早)。

【答案】

(1)地軸 1 夏至 北回歸線或23.5°N 極夜

(2)地球自西向東自轉(zhuǎn),北京位于烏魯木齊東面

(3)長

(4)短 提早

【解析】

試題分析:

(1)地球自始至終的圍繞地軸自西向東運(yùn)動,其自轉(zhuǎn)一周的時間為1天。地球在公轉(zhuǎn)時,由于黃赤交角和地軸空間指向不變,使得一年內(nèi)太陽光線的直射點(diǎn)有規(guī)律地在南北回歸線之間移動。據(jù)圖可知:上圖示意的是太陽光直射在北回歸線或23.5°N,為北半球夏至日,此時,南寒帶出現(xiàn)極夜現(xiàn)象。

(2)由于地球的自西向東自轉(zhuǎn),地球上同緯度地區(qū)位置偏東的地方,要比位置偏西的地區(qū)先看到日出,這樣不同經(jīng)度的地方就產(chǎn)生了時間差異,而北京位于烏魯木齊東面,這就是造成北京與烏魯木齊緯度相近,但日出時刻比烏魯木齊較早的主要原因。

(3)據(jù)表格結(jié)合 晝長=日落時刻-日出時刻公式可知:北京的晝長為15:01,泉州的晝長為13:42,因此北京的白晝時間比泉州更長。

4夏至日以后,太陽直射點(diǎn)逐漸向南移動,隨著太陽直射點(diǎn)的南移,泉州的白晝時間將變短,日落時間將提早。

【題目】B

On Lunar New Years Eve on Feb 18, 2015, Beijing had a good day. PM2. 5 levels were below 50. However, the nice day ended with firework celebrations at night.

In the first hour after the start of the celebration, PM2. 5 levels rose to 500 in certain parts of the city, with the average across the city around 400.

According to the China National Environmental Monitoring Center, on Lunar New Years Day, air pollution reached dangerous levels in 201 Chinese cities, because of fireworks, with more than 40 of them seeing serious pollution. As a result, the debate on whether to ban (禁止) fireworks during the Spring Festival is also heating up.

Sina surveyed 3,000 Internet users, and results show that only 38 percent of the people support setting off fireworks, and 60 percent are against it.

I support a ban on fireworks, a netizen (網(wǎng)民) nicknamed ann019 said. Lighting fireworks can only bring problems: air pollution, disturbing sleep, causing fire and exhausting sanitation workers (環(huán)衛(wèi)工人).

Others thought it to be hard to ban traditions, and lighting fireworks during holiday seasons wont cause lasting pollution.

Some, however, suggest a moderate (溫和的) way to solve the problem.

As a tradition, fireworks absolutely add to the festivals happiness. They shouldnt be banned totally, commented netizen Tracy on the China Daily online forum (論壇). But the time /span>should be reduced. For example, it can be allowed just during New Years Eve, the first day of the Lunar New Year and the Lantern Festival.

【1】___________________ caused serious air pollution on Lunar New Years Eve.

A. The factories B. The cars

C. The fireworks D. The bad weather

【2】 ___________________ cities saw serious air pollution on Lunar New Years Day.

A. 201 B. More than 40

C. Around 400 D. 500

【3】According to Sinas survey, over half of the Internet users ___________________ setting off fireworks.

A. are against B. enjoy

C. support D. dont care about

【4】___________________ was not mentioned by the netizen nicknamed ann019.

A. Exhausting sanitation workers B. Disturbing sleep

C. Wasting money D. Causing fire

【5】According to the passage, we know ___________________ is a moderate way to solve the problem.

A. to ban fireworks totally

B. to reduce the time of setting off fireworks

C. to get more people to set off fireworks

D. to never change the tradition

【題目】B

How to improve my life? Many people think that they have to accept whatever life throws at them. Theyll say, This is my fate, my destiny. I cannot change it.

Of course not! You dont have to suffer needlessly. Your destiny depends on you, not on any other outer factors. I know someone who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is? She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, then goes to sleep. Next day, the same things cycle follow.

Huh! Is this what she calls doing her best? She believes she has tried her best and just accepts it in her heart that this is the life that God has intended for her to live; that her luck can only change if God wills it. Of course God wants us to be happy and live our life to the fullest, but we have to do our share of exerting (運(yùn)用) the effort to live the life of our dreams.

Remember that you reap what you sow. You just dont sit around and wait for a million dollars to fall from the sky. You have to get off the couch, get your eyes off the TV screen, get your hands off the phone. Dont expect your luck to change unless you do something about it. If something goes wrong, dont just regard it as a temporary(臨時的) setback; but use it as feedback. Learn your lesson, make the most of the situation, and do something to solve the problem. Its not enough to think positively; you also have to act positively.

If someones life is in the trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, dont just stand (or sit) there, do something to improve your life.

【1】According to the woman mentioned in the passage, her life _______.

A. doesnt need improving B. couldnt be improved

C. will be better some day D. will be worse in the future

【2】What does the author think of the womans life?

A. Positive. B. Satisfying. C. Colorful. D. Passive.

【3】Which of the following statements is the authors opinion?

A. Your temporary problem is not discouraging.

B. Your luck can be changed by your hard work.

C. You can only achieve success when God wills it.

D. You should treat yourself in the way you treat friends.

【4】 In Para.5, the author emphasized the importance of _______.

A. positive action B. positive thinking

C. hope for the best D. intention to succeed

【5】The text is mainly written to advise you to _________.

A. understand yourself B. improve your life

C. believe in yourself D. change your normal way
