    某宽厚板车间冷床区为三跨等高厂房，跨度为35m；边列柱柱间距为10m，中列柱柱间距为20m，局部60m；采用三跨连续式焊接工字形屋面梁，其间距为10m，屋面梁与钢柱为固接。厂房屋面采用彩色压型钢板，屋面波度为1/20；檩条采用多跨连续式H型檩条，其间距为5m；檩条与屋面梁搭接。屋面梁、檩条及屋面上弦水平支撑的局部布置示意如图16-25(乙)中的(a)图所示，且系杆仅与檩条相连。

    中列柱柱顶设置有20m和60m跨度的托架，托架与钢柱采用铰接连接，托架的简图和荷载设计值如图16-25(乙)中的(b)和(c)图所示。屋面梁支承在托架竖杆的侧面，且屋面梁的顶面略高于托架顶面约150mm。

檩条、屋面梁、20m跨度托架采用Q235B钢，60m跨度托架采用Q345B钢。手工焊接时，分别采用E43型焊条和E50型焊条，要求焊缝质量等级为二级。

    20m跨度托架杆件采用轧制T型钢，T型钢的翼缘板与托架平面想垂直。60m跨度托架杆件采用轧制H型钢，H型钢的腹板与托架平面相垂直。

屋面均布荷载设计值(包括檩条自重)q=1.5kN/㎡。试问，多跨(≥五跨)连接檩条支座最大弯矩设计值(kN·m)与下列何项数值最为接近 （）

A.93.8

B.78.8

C.62.5

If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of the year. A noted scientist, Ellsworth Huntington (1876-1947), concluded from other men’s work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities.
He found that cool weather is much more favorable for creative thinking than is summer heat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.
Spring appears to be the best period of the year for thinking. One reason may be that in the spring man’s mental abilities are affected by the same factors that bring about great changes in all nature.
Fall is the next-best season, then winter. As for summer, it seems to be a good time to take a long vacation from thinking!

One possible reason why spring is the best season for thinking is that ______.

A．all nature, including man, is growing then

B．it lasts longer than the other seasons

C．it is not too warm and not too cold

D．both B and C
