Dear Jim，
It is great to hear from you．I'm writing to share my last travel experience with you．
After discussing where to go during the May Day break，my parents and I went to Xi'an．We chose Xi'an for the followingreasons．（高分句型一）As is known to all，serving as the capital city of 13 dynasties，Xi'anis often calledthe birthplace of Chinese civilization．（高分句型二）Both my parents and I are interested in Chinese history，so the historical sites in Xi'an like the Terra Cotta Warriors and the ancient city walls were at the top of my family's travel list．Also，I'm doing a project about the Silk Road．The visit to Xi'an certainly benefited my research and deepened my understanding about the importance of the trade routes．
During our stay in Xi'an，not only did I appreciate the city's long history and rich culture，but visiting Xi'an made me feel very proud to be Chinese．（高分句型三）
How about your last travel？Looking forward to your reply．
Best wishes，Yours，LiHua

18．A buld-it-yourself solar still（蒸餾器） is one of the best ways to obtain drinking water in areas where the liquid is not readily available．Developed by two doctors in the U．S．Department of Agriculture，it's an excellent water collector．Unfortunately，you must carry the necessary equipment with you，since it's all but impossible to find natural substitutes．The only components required，
though，are a 5'×5'sheet of clear or slightly milky plastic，six feet of plastic tube，and a
container-perhaps just a drinking cup-to catch the water．These pieces can be folded into a neat little pack and fastened on your belt．
To construct a working still，use a sharp stick or rock to dig a hole four feet across and three feet deep．Try to make the hole in a damp area to increase the water catcher's productivity．Place your cup in the deepest part of the hole．Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up-and out-the side of the hole．
Next，cover the hole with the plastic sheet，securing the edges of the plastic with dirt and weighting the sheet's center down with a rock．The plastic should now form a cone（ 圓 錐 體 ） with 45-degree-angled sides．The low point of the sheet must be centered directly over，and no more than
three inches above，the cup．
The solar still works by creating a greenhouse under the plastic．Ground water evaporates （蒸發(fā)） and collects on the sheet until small drops of water form，run down the material and fall off into the cup．When the container is full，you can suck the refreshment  out through the tube，and won't have to break down the still every time you need a drink．

32．What do we know about the solar still equipment from the first paragraph？B
A．It's delicate．
B．It's portable．
C．It's complex．
D．It's expensive．
33．What does the underlined phrase"the water catcher"in paragraph 2 refer to？A
A．The still．
B．The tube．
C．The hole．
D．The cup．
34．What's the last step of constructing a working solar still？D
A．Dig a hole of a certain size．
B．Put the cup in place．
C．Cover the hole with the plastic sheet．
D．Weight the sheet's center down．
35．When a solar still works，drops of water come into the cup formC．
A．the plastic tube                                                          
B．outside the hole
C．beneath the sheet                                                   
D．the open air．
