【題目】地理觀測(cè)是學(xué)習(xí)地理要掌握的基本技能。長(zhǎng)春某中學(xué)的地理興趣學(xué)習(xí)小組每天12:00準(zhǔn)時(shí)觀測(cè)記錄學(xué)校旗桿影子的長(zhǎng)度,他們發(fā)現(xiàn)不同季節(jié)影子的長(zhǎng)度不同,其原因是( )

A.地球自轉(zhuǎn)B.地球公轉(zhuǎn)C.地球形狀D.地球大小

【答案】B

【解析】

根據(jù)地球繞地軸不停轉(zhuǎn)動(dòng)，叫地球自轉(zhuǎn)。地球自轉(zhuǎn)的方向是自西向東，自轉(zhuǎn)的周期是一天。地球自轉(zhuǎn)產(chǎn)生的現(xiàn)象是晝夜交替、日月星辰東升西落和時(shí)間差異。地球公轉(zhuǎn)的周期是一年，方向是自西向東，公轉(zhuǎn)的中心是太陽(yáng)，公轉(zhuǎn)產(chǎn)生的現(xiàn)象有季節(jié)的變化、晝夜長(zhǎng)短的變化、五帶的產(chǎn)生、正午太陽(yáng)高度的變化等，進(jìn)行分析解答。

由于地球在自轉(zhuǎn)的同時(shí)，不停圍繞著太陽(yáng)進(jìn)行公轉(zhuǎn)，太陽(yáng)直射點(diǎn)在南北回歸線之間來(lái)回移動(dòng)，所以季節(jié)不同，旗桿的影長(zhǎng)不同。故選：B。

【題目】七、任務(wù)型閱讀

A life coach is somebody who helps you reach all kinds of personal and professional goals (目標(biāo)) . Each of us has the ability to be our own life coach. Here are some tips for you:

Pay attention to your relationships with others

Ask yourself the following questions: How do you deal with disagreements? When was the last time you showed your family members that you care for them? Your relationships with friends, family members and teachers show a lot about the kind of person you are.

Face the fears about the future

Now, imagine that one of your good friends told you that he or she was not strong enough to go back to school. 3 We often give better advice than we are willing to take ourselves. Remember that even the most successful people were probably told that what they wanted to do was impossible, but they followed their dreams and succeed.

Develop your talents

If you want to reach your goals, you will have to spend more time developing the talents you already have, and uncovering any hidden talents that you haven't discovered yet. So you can take classes in subjects that you are interested in, even if you have no experience.

Be thankful

Take some time to be thankful for the things you do have. Remember positive memories.4 Think of the best dav(s) you have had in the past month or year. Remember special parties, vacations and holidays. Appreciate the wonderful people you have in your life.
