                                   Come to Austria (奥地利) 
       Soll is a village in the mountains in western Austria. And the Post Hotel is
clean and not expensive. It is opened by a local family. From the hotel you can
see the whole village, the forests and the mountains. Temperatures in summer
are usually 20 to 25 in the daytime, but much cooler by evening.

       When you visit Bangkok in Thailand, don't miss the early morning river
boat trip to the Floating (漂浮) just outside the city. There you will find many
kinds of fruits and vegetables. And you can pay for them when you sit in your
boat. Don't forget your hat: the sun can be strong and it may be as hot as 40 at
noon.

                                            Visit Hawaii!
       Maybe the most beautiful place in Hawaii is Kauai. You can visit its long,

in the north, but don't be surprised if it rains in the centre of the island.
Daytime temperatures there are usually around 24 to 26 by the sea, and only
a little cooler by late evening.

填空题

生物质资源是一种污染小的可再生能源。生物质的主要转化途径及主要产物如下图。

（1）下列有关说法正确的是______________。

a．生物质能，本质上能量来源于太阳能

b．由纤维素水解获得的乙醇属生物质能

c．生物质裂解获得的汽油、柴油等属于纯净物

d．由植物秸杆等发酵获得的沼气，主要成是甲烷

（2）由生物质能获得的CO和H2，当两者1∶1催化反应，其原子利用率达100%，合成的物质可能是

______________。

a．汽油 b．甲醇 c．甲醛 d．乙酸

（3）已知在生物质气化炉中可发生：

C(s) + CO2(g) = 2CO(g) △H= 172kJ/mol

CH4(g)+ H2O(g) = CO(g) + 3H2(g) △H= 206kJ/mol

CH4(g)+ 2H2O(g) = CO2(g) + 4H2(g) △H= 165kJ/mol

则：C(s) + H2O(g) = CO(g) + H2(g) △H=__________kJ/mol。

（4）已知碳的气化反应在不同温度下平衡常数的对数值（lgK）如下表

反应：CO(g)+H2O(g)CO2(g)+H2(g)，该反应的△H________0（选填：“＞”、“＜”、“＝”）；在900K时，该反应平衡常数的对数值（lgK）=_____________。
