Cropping (修剪) an Image With the Snap Shot Program
Welcome to the world of photo-editing!
Cropping an image allows you to zero in on (对准，聚焦) just the portion that is important to your project. For example, you may want to insert an image of a covered train in a report but may not want to include the whole train. Cropping the image allows you to select only the small area you wish to retain (保留) and eliminate all other portions of the original picture.
Option 1: Cropping by Placing the Image in a Shape
Screen Shot 1
Using one of Snap Shot’s standard shapes as a photo-editing tool requires no special abilities. To crop an image with a standard shape:
a. Click Cropping & Orientation from the Effects menu.
b. Click to select one of the six shapes to frame your image.
c. Use the mouse pointer to draw a frame around the portion of the image you wish to retain. Re-size the frame by dragging the shape’s sizing handles. When you are satisfied with the results, click Cut It.
d. Snap Shot will automatically return to the project that is open. (You may also copy or cut the cropped image and paste it into another application.)
Option 2: Freehand Cropping of an Image
Screen Shot 2
If you want to trace the shape of an object in order to crop out everything else, freehand cropping is the way to go. To crop an image freehand:
a. Click Freehand Crop from the Cropping & Orientation option on the Effects menu.
b. Using the mouse pointer, trace around the shape you want to crop. Be sure to completely enclose the image by ending at the same place you began outlining.
c. Click Cut It. Snap Shot will automatically return to the project that is open.
1.The main purpose of the passage is to ______.
A. describe the features of Snap Shot
B. explain how to use Snap Shot to select sections of a picture
C. show that Snap Shot is an easy tool to use
D. discuss how to use the features of Snap Shot
2.To perform Option 2, one should first ______.
A. select the image
B. use the mouse pointer to draw a frame

3.Why is freehand cropping discussed after cropping with shapes?
A. To introduce a simpler technique before moving on to a more complex one.
B. To proceed from a more useful technique to one with fewer practical applications.
C. To order the options alphabetically.
D. To arrange the text, making space for the screen shots.
A Different Kind of Spring Break
For many American university students, the week-long spring break holiday means an endless part on a sunny beach in Florida or Mexico. In Panama City Beach, Florida, a city with a permanent population of approximately 36,000, more than half a million university students arrive during the month of March to play and party, making it the number one spring break destination in the United States.
A week-long drinking binge is not for everyone, however, and a growing number of American university students have found a way to make spring break matter. For them, joining or leading a group of volunteers to travel locally or internationally and work to address problems such as poverty, homelessness, or environmental damage makes spring break a unique learning experience that university students can feel good at.
During one spring break week, students at James Madison University in Virginia participated in 15 “alternative spring break” trips to nearby states, three others to more distant parts of the United States, and five international trips. One group of JMU students traveled to Bogalusa, Louisiana, to help rebuild homes damaged by Hurricane Katrina. Another group traveled to Mississippi to organize creative activities for children living in a homeless shelter. One group of students did go to Florida, but not to lie on the sand. They performed exhausting physical labor such as maintaining roving invasive plant species that threaten the native Florida ecosystem.
Students who participate in alternative spring break projects find them very rewarding. While most university students have to get their degrees before they can start helping people, student volunteers are able to help people now. On the other hand, the accommodations are far from glamorous. Students often sleep on the floor of a school or church, or spend the week camping in tents. But students only pay around $250 for meals and transportation, which is much less than some of their peers spend to travel to more traditional spring break hot spot.
1.How many university students travel to Panama Beach City every March for spring break?
A. Around 36,000. B. Around 50,000.
C. Around 500,000. D. Around 10,000.
2.The underlined word “binge” in paragraph 2 probably means ______.
A. doing too much of something B. studying for too long
C. refusing to do something D. having very little alcohol
3.Which of the following gives the main idea of the third paragraph?
A. One group of JMU students worked on homes damaged by a hurricane.
B. Children living in homeless shelters enjoy creative activities.
C. Some students work to help the environment on alternative spring break trips.
D. University students do different types of work on alternative spring break trips.
4.What is implied in this article is that ______.
A. university students spend more than $250 for traditional spring break trips
B. university students complain about the accommodations on alternative spring break trips
C. university students may take fewer alternative spring break trips in the future
D. university students would prefer to wait until they have their degrees to start helping people
Technology is playing a vital role in preservation and ecology research. Drones (无人机) hold huge _______ in the fight to save the world’s remaining wildlife from extinction. So researchers can now track wild animals through dense forests and monitor whales in vast oceans. It’s estimated that up to five living species become extinct every day, making it urgent that universities develop new technologies to capture the data that can persuade _______ to act.
The British International Education Association hosted a conference in January to _______ the importance of technological solutions in protecting vulnerable (易受伤害的) species and ecosystems. Speakers underlined how technology can help _______: drones can circle high above the ocean to spot whales, while certain cameras can identify members of an individual species.
According to Claudio Sillero, biology professor at Oxford University, technology is changing how preservation research is done — but it’s in a(n) _______ way. As technology gets better and cheaper, researchers become better at doing what they were already doing. _______, remote sensing used to be a very technical tool but is now widespread, and everyone uses global positioning system (GPS) for surveying.
But teaching preservation and ecology courses in university _______. Some teach drone surveying methods in depth while others don’t even mention them. “The fact is, using drones is quite a(n) _______ to the interdisciplinary (跨学科的) ‘unknown’ of engineering, and potentially an area where lecturers may not feel confident to teach yet,” Serge Wich, an expert in primate biology says. “Students are taught about _______ technologies such as automatic sound recorders, but drones are often missing from university teaching. Consequently, drone use among researchers is still fairly ________ and focused on getting photos.”
Wich’s team of researchers used techniques to develop a fully automated drone technology system that ________ and monitors the health of endangered animals globally. It’s designed to be cheap, stable and simple to use, so that local communities in developing countries can operate it ________ without technical background. Yet it’s not more widely used on the grounds of researchers’ lack of skills to use this technology. In biology, where drones are used, few can program an algorithm (算法) specifically for their preservation or research problem. “There’s much that needs to be done to ________ those two worlds and to make AI more user-friendly so that people who can’t program can still use the technology,” Wich says.
________, the sad truth is that better technology alone will not save any more species from dying out, Greengrass warns. “As human populations increase, so do threats and pressure on wild places. Preservationists are ________ for not doing enough but it’s often an issue of people, conflict and governance.” Technology may help provide far greater knowledge, but governments still need to act.
