A和B注册会计师在编制T公司2011年度财务报表的审计计划前,按审计准则的要求对被审计单位T公司及其环境进行了全面了解和记录。相关的工作底稿显示,T公司2011年度存在以下情况:
(1)2011年6月30日,T公司于2009年6月30日从P银行借入金额为6000万元、期限为两年的长期借款到期。虽然T公司最高管理人员多次与P银行信贷部协商,希望延长还款期半年,但P银行在委托K会计师事务所对T公司进行专项审计后,于2011年7月份收回了款项。
(2)为扩展业务,T公司出资1000万元于2011年6月30日成功兼并了西部某省的两家公司,此举增加了T公司在西部市场的立足点,降低了在西部市场的竞争程度。
(3)2011年10月,为开拓国际市场,T公司董事会决定在中东地区设立分公司。由于该地区除伊拉克以外的各国都是商家云集,均难以获得市场准入,公司董事会决定投入500万美元在伊拉克设立分公司。到2011年年底,该分公司已正式开始营业,虽然该地区时常发生绑架等刑事案件,但分公司的经营基本未受影响。
(4)直到2011年10月底,T公司一直采用手工记账。为提高财务工作效率和质量,T公司投资600万元于2011年11月份实现了会计电算化。考虑到这一变化对财务人员的影响,财务部门分期分批对全体财务人员进行了轮训,同时还聘请了外部专家进行经常性业务指导。至2011年年底,相关轮训工作和计算机信息系统调试工作均已进行完毕。
(5)从2011年11月起,T公司将原存放在Q银行的2 000万元款项全部转入3名高级管理人员及财务经理的信用卡,与所有客户的往来以及公司职员薪酬的发放均通过信用卡结算。

上述情况中,哪一种情况很可能会导致T公司的财务报表产生重大错报对此,A和B注册会计师应当如何应对

阅读理解。

     There are many acceptable varieties of English throughout the world. Whichever variety is

used in your country, the most important thing is that students' pronunciation must be good

enough for another person to understand what they are trying to say.

     In a PPP lesson, teachers naturally include a good model of the pronunciation when they

are presenting new vocabulary, grammar or functional language. It is important to start by

helping your students recognize sounds before you expect them to produce them.

     Spoken British English has 44 sounds, but there are only 26 letters in the alphabet for

written English. This sometimes makes English pronunciation and spelling different, so it is not

always best to write words on the blackboard at the early stages. Also, some sounds in English

do not exist in some other languages. This can make it very difficult for students to recognize

these sounds and even more difficult for them to pronounce them correctly. So some students

need to do a lot of work on these sounds, listening to them, trying to recognize them and trying

to copy them.

     If you can understand and pronounce the symbols of the phonetic alphabet, this will help

you to pronounce any word in the dictionary. You can teach this phonetic alphabet to your

students and this will make teaching pronunciation much easier. However, you can teach

pronunciation effectively without knowing the phonetic alphabet. Pronouncing English well is

not just about getting the individual sounds right. Students need to know:

* which parts of a word are stressed (spoken louder and longer);

* which parts of a sentence are stressed;

* basic intonation patterns;

* what it means when we change the intonation in a sentence (the music of the language);

* how to link together the sounds within a sentence.

     Students need practice in all these areas to improve their pronunciation.

1. The passage is most probably from ______.

A. a book for English learning

B. a book for English teaching

C. an ad for English teaching

D. a grammar book for English learning

2. Following up the passage, the author will probably ______.

A. say how to teach the phonetic alphabet

B. emphasize the importance of correct pronunciation

C. explain in detail how to practise the five suggestions

D. write about how to teach pronunciation without the phonetic alphabet

3. In the author's opinion, ______.

A. it is not necessary to pronounce every word correctly

B. the English phonetic alphabet is a must in teaching pronunciation

C. students should pronounce every word as precisely as native speakers

D. pronunciation means more than knowing how to pronounce every single word

4. Which of the following is the best title for the passage?

A. Suggestions on Teaching English Pronunciation.

B. Listening Comes First in Teaching Pronunciation.

C. The English Phonetic Alphabet and Pronunciation.

D. Other Things to Be Done besides Pronouncing Every Word.
