【题目】阅读有关图表，回答下列问题。

（1）地球自转是围绕在转动，周期约天。上图示意的是北半球节气中的日，太阳光直射在（重要纬线），南寒带出现现象。

表1：夏至日我国三城市日出日落时刻表（北京时间）

地点	经度	纬度	日出时刻	日落时刻
乌鲁木齐	87.6°E	43.8°N	06:27	21:55
北京	116.4°E	39.9°N	04:46	19:47
泉州	118.6°E	24.9°N	05:17	18:59

（2）北京与乌鲁木齐纬度相近，但日出时刻比乌鲁木齐较早，主要原因是。

（3）北京的白昼时间比泉州更（长或短）。（提示：昼长＝日落时刻-日出时刻）。

（4）夏至日后，泉州的白昼时间将变（长或短），日落时间将（推迟或提早）。

【答案】

（1）地轴 1 夏至北回归线或23.5°N 极夜

（2）地球自西向东自转，北京位于乌鲁木齐东面

（3）长

（4）短提早

【解析】

试题分析：

（1）地球自始至终的围绕地轴自西向东运动，其自转一周的时间为1天。地球在公转时，由于黄赤交角和地轴空间指向不变，使得一年内太阳光线的直射点有规律地在南北回归线之间移动。据图可知：上图示意的是太阳光直射在北回归线或23.5°N，为北半球夏至日，此时，南寒带出现极夜现象。

（2）由于地球的自西向东自转，地球上同纬度地区位置偏东的地方，要比位置偏西的地区先看到日出，这样不同经度的地方就产生了时间差异，而北京位于乌鲁木齐东面，这就是造成北京与乌鲁木齐纬度相近，但日出时刻比乌鲁木齐较早的主要原因。

（3）据表格结合 “昼长＝日落时刻-日出时刻”公式可知：北京的昼长为15:01，泉州的昼长为13:42，因此北京的白昼时间比泉州更长。

（4）夏至日以后，太阳直射点逐渐向南移动，随着太阳直射点的南移，泉州的白昼时间将变短，日落时间将提早。

【题目】B

On Lunar New Year’s 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 Year’s 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 (网民) nicknamed ann019 said. ＂Lighting fireworks can only bring problems: air pollution, disturbing sleep, causing fire and exhausting sanitation workers (环卫工人). ＂

Others thought it to be hard to ban traditions, and lighting fireworks during holiday seasons won’t cause lasting pollution.

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

＂As a tradition, fireworks absolutely add to the festival’s happiness. They shouldn’t be banned totally,＂ commented netizen Tracy on the China Daily online forum (论坛). ＂But the time /span>should be reduced. For example, it can be allowed just during New Year’s Eve, the first day of the Lunar New Year and the Lantern Festival. ＂

【1】___________________ caused serious air pollution on Lunar New Year’s Eve.

A. The factories B. The cars

C. The fireworks D. The bad weather

【2】 ___________________ cities saw serious air pollution on Lunar New Year’s Day.

A. 201 B. More than 40

C. Around 400 D. 500

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

A. are against B. enjoy

C. support D. don’t 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

【题目】B

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

Of course not! You don’t 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 (运用) the effort to live the life of our dreams.

Remember that you reap what you sow. You just don’t 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. Don’t expect your luck to change unless you do something about it. If something goes wrong, don’t just regard it as a temporary(临时的) setback; but use it as feedback. Learn your lesson, make the most of the situation, and do something to solve the problem. It’s not enough to think positively; you also have to act positively.

If someone’s 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, don’t just stand (or sit) there, do something to improve your life.
