San Francisco has many museums. You can visit one and learn s     new. We have arts, science, history and other special museums. Some museums are o    every day. Some are only open o    certain days. Many museums are expensive, and others are f  . But some of the expensive o    have free days. Many museums have websites. The websites usually have information about the things you can see in the museums.
On a museum’s website you can get i   about ticket prices and free days. You can also know w     the museum is and when it is open. Sometimes the information is on the first page, and it’s very e   for you to find. But sometimes you have to click on (点击) the w    like Visit Information, or About to find the information. That will be hard w     for you.
