You do everything out together,too,(1)____________________. That’s what life is like for six-year-old Betty and Abby. Like most twins, the two girls look very much alike,but unlike most twins,Betty and Abby share parts of the same body .Twins like Betty and Abby are rare. Only about 40 sets are born in the United States each year. Few survive as long as Betty and Abby .(2)______________________. The shared organs are often badly shaped and may not be strong enough to support both twins. But Betty and Abby each has her own head, heart and stomach which function normally .Because she has three or four lungs which provide plenty of oxygen for both twins. Most of their completely shared organs lie below the waist. Betty And Abby live relatively normal lives.They attend a regular school ,and each does her own school work .They prefer to do some projects together,though ,for example,(3)______________________. But sometimes,the girls don’t want to do the same thing, for example, sometimes they want to play with different toys. What do they do then? "We toss a coin", says Abby.
