The first "test tube baby" is a mother herself now, and she’s been joined by millions of others born with the (47) of in vitro fertilization (体外受精), or IVF. Now specialists wonder whether people who were conceived by IVF are likely to be (48) . "By and large, the kids are just fine. It’s not like the kids having (49) arms or heads," says Carmen Sapienza, a scientist at Temple University. But none is older than their early 30s, and the vast (50) are under the age of 20, so they haven’t had time for long-term health problems to show up. One source of worry is that so many IVF babies have low birth weight. Children-conceived through IVF are more likely to (51) less than 2.5 kilograms than are babies conceived (52) . That could spell trouble ahead, because low-birth-weight babies often have long-term health problems. They’re more likely to be obese, to have diabetes (糖尿病) or other problems. With that in mind, Sapienza and colleagues have looked at genes that are likely to play a role in such health problems. They found that certain DNA-patterns, which affect how genes are (53) , are different between IVF and non-IVF children. There’s no way to tell if that’s because of the (54) used to produce the IVF babies or whether the difference has something to do with the underlying infertility problem the parents had.

Scientists in California asked a group of (41) to act five different feelings: happiness, sadness, (42) , surprise and fear--just using their faces. Changes in their heart rate, blood pressure and temperature were (43) down. Most of the feelings they acted didn’t cause changes, but when they smiled their heart rate and their blood pressure went down. (44) . A sense of humor also helps to keep things in perspective.
