56 From  sentence  [18b],  it  can  be  seen  that  there  was  illogical  conditional
sentence. Based on the fact in the sentence [18a], it consists of the cause and the result.  Therefore,  sentence  [18b]  was  not  suitable  with  the  fact.  The  “result
clause”  of  the  correct  conditional  sentence  should  be  “was  not  injured”,  but  in sentence [18b] the “result clause” was “wearing seatbelt.” Besides, the pattern of
the conditional sentence used was incorrect. [21] a.  Question:  I  didn’t  get  a  taxi  because  I  didn’t  have  any  money  on
me. b.  Student’s  answer:  If  I  had  any  money  on  me,  I  would  have  got  a
taxi. P. 42 c.  Intended answer: If I had had some money, I would have got a taxi.
Basically, the pattern in sentence [21b] was already correct. Although the pattern was already correct, this sentence was still considered wrong. In sentence
[21b],  the  student  forgot  the  word  “any”,  which  should  be  changed  into  some. “Any”  is  used  for  negative  sentences  and  “some  is  used  for  positive  sentences
Murphy, 1985: 168. [24] a.  Question:  I  was  able  to  buy  the  car  only  because  Jim  lent  me  the
money. b.  Student’s answer: If Jim had not lent me the money, I would have
been able to buy the car. P. 37 c.  Intended answer: If Jim hadn’t lent me the money, I wouldn’t have
been able to buy the car.
57 Sentence [24b] had already used the correct pattern. The problem was the
meaning of sentence [24b] was different from the fact given. It should be included “not” in the “result clause” after “would.”
[27] a.  Question: He took the taxi, so he caught the plane. b.  Student’s  answer:  If  he  had  taken  the  taxi,  he  would  caught  the
plane. P. 46 c.  Intended  answer:  If  he  hadn’t  taken  the  taxi,  he  wouldn’t  have
caught the plane Grammatically,  sentence  [27b]  was  incorrect.  The  verb  followed  the
auxiliary verb was incorrect. Moreover, if the conditional sentence was in positive form,  the  fact  would  be  in  the  negative  form.  Therefore,  sentence  [27b]  was
incorrect.
2. The Factors Which Cause the Students to Make Errors
The  factors  which  cause  the  fifth  semester  students  of  English  Education Study Program of Sanata Dharma university was obtained from collecting the data
of  students’  experience.  In  this  case,  the  researcher  used  questionnaire  to  collect the  answers.  After  that  the  writer  analyzed  the  students’  responses.  The
presentation of the students’ responses was divided into five criteria based on the aspect of investigation. The first was the students’ perception, the second was the
students’ ability the third was the students’ motivation and effort, the fourth was the  teaching-learning  activities  and  the  last  was  the  time,  class  and  social
influences. Each criterion consisted of six numbers. The results were presented as follow.

Figure 4.1: The Percentage of the Students’ Responses on the First Aspect
Figure  4.1  shows  the  percentage  of  the  students’  response  on  the  first criterion.  The  first  criterion  was  aimed  to  know  the  students’  perception  on  the
conditional  sentences  generally.  From  the  result,  it  can  be  seen  that  on  the  first item  there  were  49.12  of  the  students  agreed  and  50.88  of  the  students
strongly  agreed  with  the  given  statement.  It  means  that  all  of  the  fifth  semester students  of  the  English  Language  Education  Study  Program  agreed  that
conditional  sentences  topic  was  important  to  learn.  The  second  item,  there  were four different answers, but most of the students agreed with the given statement.
There  were  59.65  of  the  students  agreed  that  conditional  sentences  were  a difficult  topic.  Besides,  there  were  14.04  of  the  students  who  strongly  agreed
with  the  given  statement.  Then,  most  of  the  students  agreed  that  conditional sentences  were  confusing.  It  can  be  known  from  the  third  group  of  bars.  The

59 figure  shows  that  64.91  of  the  students  agreed  that  conditional  sentences  were
confusing.  On the fourth item, there were 59.65 of the students who agreed that conditional  sentences  were  complicated.  Although  most  of  the  students  agreed
that  conditional  sentences  were  difficult,  complicated  and  confusing,  they  were still  interested  in  learning  the.  It  can  be  seen  from  the  fourth  group  of  bars  that
there  were  57.89  of  the  students  who  agreed  and  17.54  of  the  students  who strongly agreed with the given statement. The last item on this first aspect showed
that 49.12 of the students were curious to learn conditional sentences topic more because of its many types.
Figure 4.2: The Percentage of the Students’ Responses on the Second Aspect
The  second  criterion  was  students’  ability.  This  criterion  was  aimed  to know the students’ ability in learning conditional sentences. Figure 4.2 shows that

60 most of the students admitted that they have already known conditional sentences
before they entered to the university. It can be seen from the figure that 49.12 of the  students  agreed  with  the  given  statement.  The  result  on  the  next  item  shows
that most of the students faced difficulty in learning conditional sentences because of  the  differences  pattern  of  conditional  sentences  in  their  second  language  and
first  language.  It  can  be  seen  from  the  Figure  4.2  that  there  were  43.86  of  the students  who  agreed  with  the  given  statement.  Although  they  faced  difficulty,
there  were  49.12  of  the  students  who  agreed  that  they  could  automatically determine the types and patterns of conditional sentences by looking the question.
In fact, they were still confused in determining the types and patterns. In order to understand conditional sentences well, 50.88 of the students strongly agreed that
they need to review it again at home. From Table 4.9 it also can be seen that there were  59.65  of  the  students  who  agreed  that  they  could  easily  understand  the
types of conditional sentences by only studying class. Yet, there were 45.61 of the  students  who  agreed  that  they  could  easily  understand  conditional  sentences
by learning them at home themselves. Besides, 45.61 of the students disagreed with that statement.
The  third  criterion  was  students’  motivation  and  effort  and  it  was presented  in  Figure  4.3.  Most  of  the  students  had  high  motivation  in  learning
conditional  sentences  because  they  liked  the  topic.  There  were  50.87  of  the students  who  agreed  that  they  had  high  motivation.  After  that,  57.89  of  the
students  were  challenged  to  learn  conditional  sentences  because  they  were difficult.  There  were  61.40  of  the  students  who  disagreed  that  they  had  no
61 motivation  in  learning  conditional  sentences  because  the  confusing  conditional
sentences. Beside their motivation above, there were 42.11 of the students who tried  to  ask  to  the  lecturer  when  they  faced  difficulties  in  learning  conditional
sentences. Yet, some of the students still had no effort to find other literatures to help them to understand conditional sentences. It can be seen from the Figure 4.3
that  there  were  42.11  of  the  students  disagreed  with  the  given  statement.  The next result shows that 63.16 of the students disagreed that they were diligent in
learning  conditional  sentences.  That  was  the  reason  why  the  fifth  semester students  of  the  English  Language  Education  Study  Program  faced  the  problem
such as easy to forget and difficult to understand the conditional sentences.
