the ice and caught the stick of dynamite with the burning 40­second fuse about the time it hit the ice. The two men shouted loudly, waved their arms and wondered what to do now. The dog, cheered on, kept running.

　　One of the guys grabbed the gun and shot the dog. The shotgun was loaded with very small bullets (子弹)，hardly big enough to stop a dog.

　　Ⅴ.任务型阅读

　　While many people are accessible by e­mail, sometimes it is difficult to determine how exactly to write an e­mail to them. Here are some tips for you to follow.

　　Write an appropriate subject line. The subject line should tell the recipient (接收者) immediately what the e­mail is about. 1.________ Remember that your wording also has to be brief.

　　2．________ It is best to be more formal rather than informal, so when writing to someone you have never met or written to before, a "Dear Jane Smith" is appropriate. When addressing someone whom you are a little familiar with, a "Dr. Smith" is okay until they tell you to address them by their first name, in which case a simple "Jane" will be okay.

　　3．________ Within the first two sentences of your e­mail, your recipient should know exactly why you are writing to them. Sometimes an introduction may have to precede (先于) the sentence that states why you are writing, and sometimes it has to follow.

　　Use appropriate language. You may be used to using informal language in certain social settings. 4.________ Even when dealing with colleagues or friends you are familiar with, do not immediately fall back on informal language.

　　Keep it simple. People may get dozens and even hundreds of e­mails a day. 5.________ In that way, they can save much of their time when reading e­mails.

　　A．Use proper greetings.

　　B．Express your ideas clearly.

　　C．State your purpose at the beginning.

　　D．Be as specific as possible when writing the subject.

　　E．However, an e­mail may not be the best place to use such language.

F．It is important to check the language to avoid spelling and grammar mistakes.
