16．Having a dental fear（牙科恐惧症）is a common problem．Learning to overcome your fear of the dentist is possible with a little determination and guidance．It is worthwhile to overcome the issue as healthy teeth might help you be healthy physically and spiritually．
Admission
Admitting you have a fear is the first step in overcoming dental fear．When you acknowledge your fear，you can start the process．Dentistry has come a long way over the years．The anesthetics（麻醉）are improved，the techniques are of higher quality and dental offices have a better understanding of these issues you are concerned and all these can help you overcome it．
Research
Speak to family and friends about your fear．Be open and honest about your issues and get feedback from them regarding their dental experiences．You can contact your local Dental Society and express your concerns．Another good approach is to simply call dental offices and get useful information from the front office staff．
First visit
Most dental offices schedule your first visit by a dental assistant．This gives you a chance to ease into the situation．Do not hesitate to express your fear and hesitation．Pay attention to what the assistant says．It can be very useful and it can gently guide you to a new attitude towards dentists．
Relaxation techniques
There are many things you can do to relax yourself．Slow，steady，deep breaths are keys to relax properly．Another aid in relaxation is to bring your iPod to play some relaxing music while you are in the dental chair．Music is a wonderful tool to use and is a helpful distraction．

Dear Sir/Madam，
I am writing to make a complaint．This Dragon Boat Festival holiday I，as well as my family with great expectations of relaxing and enjoying ourselves，paid a visit to the famous tourist attraction，Tianlongshan National Forest Park．（高分句型一）However，I felt very disappointed at what I had experienced there．
As we got closer to the park，we found it more difficult for us to move forward，as many drivers parked their cars where they shouldn't park and cyclists put their bikes wherever they could，which badly blocked the way to the park．（高分句型二）Hardly had we got off the coach when we were surrounded by the vendors，whom we could hardly get rid of，trying their best to sell their goods．（高分句型三）To my relief，we finally managed to reach the forest area，and the fresh air and beautiful scenery there made me intoxicated．But the rubbish，such as fruit skins，food packages and plastic bags thrown here and there by tourists spoiled the view and my good mood．What's worse，the toilets are dirty and stinky．Apart from that，too many people and confusing road signs exhausted me and my patience．
Needless to say，it's time to take actions immediately to improve the unsatisfying conditions．I think，for example，more workers should be arranged to solve the problems of disorderly parking，and perhaps selling tickets online in advance is a good way to avoid the park being too crowded．（高分句型四）I hope in the near future the National Forest Park will become true to its name．I look forward to your reply．
Thank you for your consideration
Sincerely yours，
Li Hua．

18．It may seem like a moment in a science fiction movie．In a fierce battle，a creature loses an arm but，then，grows another one to take its place．
However，this is not science fiction．It is scientific fact．Some fish and amphibians，such as salamanders，can regrow lost limbs and organs．
As mammals evolved they lost the ability to regrow，or regenerate，parts of their body．However，experiments show that it may be possible to regain that ability．
Tropical freshwater zebrafish are popular pets．They are also popular as lab animals．Their embryos（胚胎） are clear，or translucent．They can regrow damaged fins，skin and hearts．Zebrafish are also genetically（基因地） similar to humans．
In 2013，the website Sci-News reported that researchers had found that 70per cent of"protein-coding human genes"are related to genes found in the zebrafish．The report also said that researchers at the Wellcome Trust Sanger Institute in Britain also found that 84per cent of genes known to be connected to human disease have a zebrafish counterpart．
Scientist Wang Yadong is one of the Pittsburg researchers．He and his team are studying the ability of zebrafish to regenerate limbs and organs．Wang says you can cut away about 20per cent of the zebrafish heart and it will regenerate．He add that same process may be able to help humans．
Scientists injected（注射） an"extracellular matrix，"or ECM，from the heart of a zebrafish into a severely damaged mouse heart．They found that the heart muscle regrew in days．They found something else．The healing was even faster when the ECM was taken from zebrafish that was itself in the process of re-growing damaged tissue．

12．The main reason why the zebrafish were chosen as lab animals is thatC．
A．they are popular pets
B．their bodies are clear to study
C．they are genetically similar to humans
D．they are easy to find for the researchers
