Women with an hour glass figure have brains to go with their curves(曲线)，scientists claim.

Going in at the waist is said to be a sign of intelligence which leads to brighter children, too,Wonmen such as Nigella Lawson with a big difference between thir waist and hip measurements scored significantly better in tests than those with thinner,straighter frames,, Researchers concluded that it was not necessary for a woman to be skinny-what mattered was that her waist should be smaller than her hips, A ratio of 3:5 was found to be idea,

The study ,by the Universities of Pittsdburgh and California,involved 16,000 women and girls,

According to the scientists，the results are no mere quirk of nature．They claim that the fat

Around culvy hips and thighs(大腿)holds higher levels of-3 fatty acids which are essential for

the growth of the brain during pregnancy．The fat which collects around the waist，howover．is

more likely to contain-6 fatty acids，which areless suited to brain growth．

Reporting in the joumal Evolution and Human Behaviour，the researchers found that the children of curvy mothers are more likely to do well in cognitive tests than others．they claim that  this could help explain why the children of teenage mothers．who might not yet be physically mature enough to have developed real curves-tend to do less well in school．

As wel las boosting(提升)brainpower,一3 fatty acids found in oily fish arc considered to be of huge health benefit Although the study analysed women’s bodies only,一3 fatty acids are also stored in men’s hips ,However it is not known whether men with wide hips benefit from the same brain power boost,．

72.Which shows the possible shape of an hour glass?    

73．Suppose the following measurements are taken from four women．Which of them is more likely to have bright children?

A. Waist：60cm；Hip：100 cm            B．Waist：60cm：Hip：80cm

C. Waist：55 cm；Hip 1 60cm            D．Waist：120cm；Hip：110cm

74.The underlined sentence‘'the results are nomere quirkofnature，'possible tells us the results

A. can be explained scientifically    B are strange and hard to explain

C. have just come about by chance   D are very interesting

75．According to the researchers，teenage mothers tend to have less bright children because

A．they aren’t so good at child care

B．they usually have less fat than mature women

C．they area’t physically strong enough

D．their waist and hip measurements differ less
