Adventure Travel Ad Are you looking for a little adventure in your life? Travel with me to beautiful Colorado. I’m an experienced river rafting and rock climbing guide. I’ve been guiding adventure travelers in this area for 10 years. In fact, last year, I took 30 trips down the Colorado River. Oh, and don’t worry about safety. I’ve also taken a number of first aid and safety courses. No one has ever broken any bones on my trips!

Use ago to show when something started. Simple Past 1 Use the simple past to talk about things that happened and were completed in the past. I rafted down the Nile River a year ago. I kayaked in the Grand Canyon for two months. rafted past now future kayaked Use ago to show when something started. He’s not kayaking now.

have guided have been rock climbing Perfect Tenses 1 Use the present perfect and the present perfect progressive to talk about things that started in the past, but were not completed. I have guided travelers my entire career. I have been rock climbing for 10 years. past now future have guided have been rock climbing These things continue up to the present and may continue into the future.

Remember! I’ve been knowing how to rock climb since I was young. Non-action (stative) verbs are not usually used in the progressive. I’ve been knowing how to rock climb since I was young. I’ve known how to rock climb since I was young.

Perfect Tenses 2 I have trained for six years to take this trip. We often use the present perfect and the present perfect progressive with for and since. Use for to show how long something has been true and since to show when something started. I have trained for six years to take this trip. for six years He has been guiding trips since 2000. since 2000. past now future for six years have trained has been guiding since 2000

Simple Past 2 We trekked through the Andes Mountains last year. Use the simple past with past time expressions. We trekked through the Andes Mountains last year. last year. He backpacked in Peru two months ago. ago. past now future trekked backpacked

Be Careful! Don’t use specific time expressions with the present perfect except after since. She has taken skydiving lessons last year. last year. She took skydiving lessons last year. last year. She has taken skydiving lessons since 2004. since 2004.

Present Perfect 1 They have canoed down the Amazon River. past future Use the present perfect without time expressions to talk about things that happened at some indefinite time in the past. They have canoed down the Amazon River. time ???? past now future We don’t know when they canoed down the river, or the time is not important.

Present Perfect 2 He has visited Machu Picchu three times. The present perfect without for or since shows that an activity is finished. We often say how many or how many times with this use of the present perfect. He has visited Machu Picchu three times. three times. past now future

Present Perfect Progressive The present perfect progressive shows that an activity is unfinished. We often say how long with the present perfect progressive.

Present Perfect & Simple Past Use the present perfect or the simple past with unfinished time periods such as today, this week, this month, and this year. Notice the difference in meaning. She’s traveled to Alaska twice this month. The month isn’t over. She might travel again. this month. The month isn’t over, but she probably won’t travel again this month. She traveled to Alaska twice this month. this month.
