This is an appeal from a conviction of burglary of a habitation with intent to commit rape. Appellant contends that (1) it was error to admit testimony regarding two extraneous offenses, (2) the trial court erred in not granting a continuance, and (3) the prosecutor made improper jury argument. We disagree and, thus, affirm.
Initially, appellant complains of the admission of two witnesses’ testimony concerning extraneous offenses. Appellant concedes that evidence of extraneous offenses became admissible when appellant’s identity was put in issue by his alibi defense. Jones v. State, 587 S.W.2d 115, 119 (Tex.Crim.App.1979); Albrecht v. State, 486 S.W.2d 97, 100-01 (Tex.Crim.App.1972). He argues, however, that the two extraneous offenses are so remote and dissimilar from the offense in this case that any probative value is greatly outweighed by their prejudicial effect, thus rendering them inadmissible. Ransom v. State, 503 S.W.2d 810, 812 (Tex.Crim.App.1974).
Upon appeal, our review of the admissibility of extraneous offenses must be de novo — that is, we must make an independent examination of the testimony rather than determine if the trial court’s conclusion is supported by the record. Carpenter v. State, 596 S.W.2d 115, 120 (Tex.Crim.App.1980). An extraneous offense is admissible to prove identity if there is some distinguishing characteristic common to both the extraneous offense and the offense for which the accused is on trial. Ford v. State, 484 S.W.2d 727, 729 (Tex.Crim.App.1972). “The common distinguishing characteristic may be the proximity in time and place of the extraneous offense to the offense for which the accused is being tried. Or, the common element may be the mode of commission of the crimes, or the mode of dress of the perpetrator, or any other element which marks both crimes as having been committed by the same person.” Ford, 484 S.W.2d at 729-30. When the accused is clearly identified and shown to be the perpetrator of the extraneous offense, however, the mere fact that certain dissimilarities are present does not make the extraneous offense inadmissible. Ransom, 503 S.W.2d at 813. With these standards of review before us, we turn to the facts of the primary offense and to those of the two extraneous offenses.
*426 Primary Offense — K.B.
K.B., the complainant, testified that she lived in a house with her brother in Northwest Dallas. At about 3:30 to 4:00 a.m., on May 31, 1982, Memorial Day, she was at home alone. She was awakened by the sound of her glass backdoor being broken. K.B. locked her bedroom door, but appellant broke down the door and entered her bedroom, attempting to conceal his identity by pulling his T-shirt over part of his face. His arm had been badly cut when he broke the glass door. He was carrying a revolver. Appellant ordered K.B. to remove her nightgown. He then ordered her into another part of the house. He forced her to her knees and forced her to perform oral sodomy on him. He then took K.B. out the back door, through the backyard, into an alley, and down the alley into the next block. At that point he again forced K.B. to perform oral sodomy on him and then raped her. Appellant then sat down and started talking to K.B., saying that he wished she had a gun so that when he broke into her home she could have shot him. He then told her to walk back to her house slowly. When she reached her back gate, she turned around to find appellant was gone. K.B. positively identified appellant as her assailant.
Extraneous Offense — P.H.
In rebuttal, the State called P.H. who testified that she lived in a house with her sister in Northwest Dallas. (The testimony revealed that appellant’s brother also lived on this block of this street.) At about 11:45 p.m., on May 25, 1980, the day before Memorial Day, she was at home alone. She was in her bathroom when she heard her backdoor open. She shut the bathroom door, but appellant forced the door open and entered the bathroom. Appellant attempted to conceal his identity by covering his face with his sweatshirt. He then forced P.H. to undress, made her perform oral sodomy on him, and attempted sexual intercourse with her. He then bound her arms, took her through her backyard, into the alley, and down the alley a distance of about three or four houses. He made her again perform oral sodomy on him and then raped her. Appellant then told P.H. to go home and take a bath. P.H. positively identified appellant as her assailant.
Extraneous Offense — L.B.
The State also called L.B. as a rebuttal witness. She testified that she lived in a house with her common-law husband in North Dallas. On April 16, 1981, she was at home alone. At about 10:00 p.m., she fell asleep watching television but was awakened when appellant grabbed her and held a revolver to her head. He attempted to conceal his identity with a ski mask, but the mask was pushed off during a struggle. Appellant took L.B. to the living room where he made her open the drapes. He then forced her to her knees and forced her to commit oral sodomy on him in front of the open window. He then pushed her to the floor and told her to remove her nightgown and cover her face with it. L.B. complied and appellant raped her. He then told her to go take a shower. When she came out of the shower, appellant had left. L.B. positively identified appellant as her assailant.
In considering the P.H. extraneous offense, we take judicial notice that the offense was committed within several blocks of the primary offense.1 Both offenses occurred during the nighttime hours before Memorial Day. In each case, the victim lived in a house with someone else but was at home alone at the time of the offense. The appellant entered each house through the rear and attempted to conceal his identity during both offenses by cover*427ing his face with a T-shirt or sweatshirt. Each victim was first forced to commit oral sodomy in the house and was then taken out through the backyard, into an alley, and some distance down the alley. Each was again forced to commit oral sodomy before being raped. Finally, they were both instructed to return home and appellant did not follow. We find sufficient similarities to render this extraneous offense admissible.
The L.B. offense was also committed in the same area of the city as the instant offense — within about one mile.2 L.B. also lived in a house with someone else but was alone at the time of the offense. The appellant used a revolver in both offenses. As in the primary offense, appellant attempted to conceal his identity — first by covering his face with a ski mask and then by ordering L.B. to remove her nightgown and cover her face with it. Appellant forced each of the victims to commit oral sodomy before he raped them. In each case, appellant made his escape by telling the victim to go somewhere else and then leaving while she was not looking. We find sufficient similarities to also make this extraneous offense admissible.
In addition to contending that the extraneous offenses do not possess sufficient similarities, appellant also argues that the offenses are too remote. The State contends that appellant failed to raise the remoteness issue at trial because he did not specifically object on this ground. We do not find the authorities cited by the State to be controlling as those cases involved admitting prior convictions for impeachment purposes. See Horn v. State, 491 S.W.2d 170 (Tex.Crim.App.1973); Brem v. State, 432 S.W.2d 916 (Tex.Crim.App.1968). Remoteness is simply one factor to be considered in determining the admissibility of an extraneous offense. Ford, 484 S.W.2d at 729-30. Appellant was not required to specifically object on the ground of remoteness and, therefore, his objection was sufficient to preserve the matter for review on appeal. Buckner v. State, 571 S.W.2d 519, 524-25 (Tex.Crim.App.1978).
We conclude, however, that the offenses are not so remote as to render them inadmissible. As we have stated, proximity in time is but one factor to be considered in determining the admissibility of extraneous offenses. The testimony in this case provides other similarities which we hold sufficient. Furthermore, the presence of an intervening similar offense works to ameliorate an otherwise too-remote offense. See Bachhoffer v. State, 633 S.W.2d 869, 872 (Tex.Crim.App.1982) (four years with no intervening offense held too remote); McDonald v. State, 513 S.W.2d 44, 52 (Tex.Crim.App.1974) (one year with intervening offense held not too remote).
Appellant next complains of the trial court’s denial of his oral motion for continuance. He argues that he was surprised by the testimony of P.H. and L.B. because he had no notice that they were going to testify at trial. When an appellant claims surprise, a motion for continuance is addressed to the sound discretion of the court. Hightower v. State, 629 S.W.2d 920, 926 (Tex.Crim.App.1981); TEX.CODE CRIM.PROC.ANN. art. 29.13 (Vernon Pamp.Supp.1984). We note that the State did not offer this testimony in its case-in-chief, but in rebuttal to a defensive issue raised by appellant. “In such a situation the defendant, rather than the State, determines whether a contested issue will be raised, and his determination will not be made known until he presents his case.” Gipson v. State, 619 S.W.2d 169, 170-71 (Tex.Crim.App.1981). Appellant’s motion was neither in writing nor was it sworn to. Therefore, it did not comply with TEX. CODE CRIM.PROC.ANN. arts. 29.03, 29.-08 (Vernon Pamp.Supp.1984). Porter v. State, 623 S.W.2d 374, 381 (Tex.Crim.App.1981). Under these circumstances, we find no abuse of discretion in denying the motion for continuance. Hightower, 629 S.W.2d at 926.
*428Finally, appellant complains of two instances of improper jury argument by the prosecutor. In the first instance, appellant failed to secure a ruling on his objection and, thus, preserved nothing for review. Todd v. State, 598 S.W.2d 286, 296 (Tex.Crim.App.1980). In the second instance, the prosecutor made the following argument:
Now, I’m not going to beat a dead horse standing up here, you also know that her [the complainant’s] testimony is corroborated by P.H. and by L.B. No doubt about it, I mean, these aren’t people we made up, these aren’t actresses, there are really just women that were living here in Dallas trying to earn a decent living and who happened to fall victim to him over here. When he gets a little time on his hands he doesn’t know what to do with himself and he goes out and rapes somebody, on Memorial Day, twice. Then on April 16th, the other time. So that corroborates K.B.’s testimony, too. The revolver, taking them out in the alley, you know, that business. And they’re identifying him, too. They didn’t say, I think it’s him, it might be him, it resembles him. If they said, that’s him. They also passed the eyewitness identification test, too. L.B. picked him out of a six-picture lineup. P.H. picked him out of a six-man lineup. Nobody missed him once. Now, you-all set the policy here and you tell us what you want. You know, three people came down to the D.A.’s Office, the police catch the guy and they say, here he is, this is the guy that rapes—
MR. ROBERTSON: Judge—
MR. ANDERSON: —what do you want us to do?
MR. ROBERTSON: —I’m going to object to other cases that he’s referring to, it’s outside the scope of the evidence.
THE COURT: Overrule the objection.
MR. ROBERTSON: Note our exception.
Appellant contends that, because the extraneous offenses were admitted for a limited purpose, it was error to allow the prosecutor to suggest to the jury that the offenses are evidence of appellant’s guilt. We do not interpret the prosecutor’s argument to be a suggestion of guilt. It is clear that the prosecutor was asking the jury to consider the testimony of P.H. and L.B. as evidence of appellant’s identity — the purpose for which the offenses were admitted. As such, the argument was a proper summation of the evidence. Alejandro v. State, 493 S.W.2d 230, 231 (Tex.Crim.App.1973).
Affirmed.
