Your English is just fine (I've seen plenty worse from people who were born & raised in the US).
While not common, Bettes is not an unusual name.The following could be him but no way for me to know:
U.S. World War II Army Enlistment Records, 1938-1946 about Ralph E Bettes Name: Ralph E Bettes Birth Year: 1925 Race: White, citizen Nativity State or Country: Oklahoma State: California County or City: Contra Costa Enlistment Date: 28 Jul 1943 Enlistment State: California Enlistment City: San Francisco Branch: No branch assignment Branch Code: No branch assignment Grade: Private Grade Code: Private Term of Enlistment: Enlistment for the duration of the War or other emergency, plus six months, subject to the discretion of the President or otherwise according to law Component: Selectees (Enlisted Men) Source: Civil Life Education: 1 year of high school Civil Occupation: Welder, Spot or Burner, Acetylene Marital Status: Separated, without dependents
The following could be same person as above but, again, no way for me to verify.Using the certificate number it should be possible to locate the death info although I must warn you death certificates are not always accurate nor do they have complete info.Local libraries may have a copy of his obituary & it could contain information about his military service so that you could verify it is same man.
