Unit 6 Disaster and hope
一、阅读理解（本大题共4小题，共8.0分）
A
Rescue workers and thousands of volunteers are not the only ones who have won hearts and minds for their heroic efforts in the search for survivors after Tuesday's powerful earthquake in Mexico. Fifteen dogs from the navy's canine (犬的) unit have also helped this week in the rescue efforts.
Of the canine heroes none is more famous or loved than Frida, a six-year-old white Labrador who has won praise for her ability to perceive people who have been trapped by various natural disasters. Over her admirable career she has found 52 people including 12 survivors in Mexico and other Latin American countries.
This week, Frida together with another two dogs was sent to the site of the collapsed (坍塌的) Enrique Rebsamen school in southern Mexico City. Equipped with large glasses that protect her eyes from dust and smoke, boots to prevent damage to her paws while she climbs over rough ruins, Frida took to her work searching every part of the ruins. If Frida detects the presence of a survivor, she is trained to bark (吠叫) to remind rescue workers.
Eleven children were rescued from ruins at the school but this time human rescue workers rather than the dogs were the ones who located them. However, that hasn't stopped Frida from becoming a social media star and reaching a new level of fame this week. Videos and other social media posts that highlight the work of Frida and her impressive record of detecting people trapped by natural disasters spread quickly online.
While she has yet to detect anyone trapped in the ruins this week, she and other rescue dogs are continuing to work tirelessly, searching through spaces that humans cannot reach. With the possibility that there are still people trapped alive, time will tell whether she adds to her rescue record.
1. What does the underlined word "perceive" in paragraph 2 probably mean
A. Notice. B. Grab. C. Protect. D. Comfort.
2. What makes Frida a social media star
A. Her discovery of eleven children.
B. Her rescue record and tireless work.
C. Her cool appearance with some special devices.
D. Her ability to search spaces beyond humans' reach.
3. What can be inferred from the last paragraph
A. Frida will be out of the rescue.
B. Frida will probably work wonders.
C. More dogs will be sent to the area.
D. Dogs will take the place of human workers.
4. What's the best title for the text
A. Severe earthquakes in Mexico B. Impressive rescue work
C. People waiting for rescue D. Special rescuers in Mexico

How to Pick a Good Book It's not news that we spend more time texting and surfing the Internet than ever. But a recent study shows that more teenagers are reading good old-fashioned and ink-on-paper books. Reading is a good way to widen your knowledge and learn about yourself. (1) Here are some tips.
Start with your interests
Reading on your own isn't like reading for school. (2) It could be ancient martial arts, computers, or fashion design. If you can name the subject, you can find books about it.
Find your "type"
Do you prefer fiction or non-fiction Books of fiction, like novels or short-story collections, can transport you to another world or help you to imagine something beyond your own experience. Not all fiction is the same. Try some different types of fiction and see which one you prefer. Non-fiction books give you the "who", "what", "when" and "why" of something. (3)
Read the "blurb" (简介)
The reviews and quotes on the back and inside covers of many books are known as "blurbs". (4) If you find a book you really like, take a minute to read the blurb and see which authors praised the book. Often, they will have similar styles, and you might find you like books by those authors, too.
(5)
Your local library can provide you with a lot of great books. Explain your interests and mention any writer you like, and the librarian can point you towards books that you will like. Then you can enjoy what you're reading in a quiet place.
A. Ask an expert.
B. Read in a quiet place.
C. You can pick something that suits your interests.
D. But do you know how to pick a book that you will really like
E. They tell stories using facts, but that doesn't mean they are boring.
F. It is necessary to work out what the book is about before reading.
G. These not only give you an idea of what the book is about, but also help you pick future books.
5. A. A B. B C. C D. D E. E F. F G. G
6. A. A B. B C. C D. D E. E F. F G. G
7. A. A B. B C. C D. D E. E F. F G. G
