B
Zora Neale Hurston proves to be a study in contrasts a black writer reaching a white audience,a woman struggling in a man's profession,an independent thinker living in a conformist(墨守成規(guī)的) era. Now,almost 50 years since her death,her hard work and great novels still have much to teach the modem audience. She overcame the challenges she faced and showed that determination makes anything possible.
Hurston thought much of her deeply individualistic personality was developed because of the experience of growing up in Eatonville,Florida. The town was unique in that it was particularly hot in the summer,but mild at other times of the year. Hurston always said growing up in a community totally separate from the larger white society allowed her freedom and independence not available to everyone in the south.
Hurston began her undergraduate studies at Howard University,but her obvious intelligence and talent soon earned her a scholarship to Barnard College in New York City. Moving north in the 1920s helped her get to know the Harlem Renaissance,a black cultural movement that produced exceptional achievements in literature,art,and music. Communicating with the likes of Langston Hughes,W.E. B. DuBois,Billie Holiday,and Duke Ellington,Hurston developed her skills as a writer and published lots of short stories and poems.
Her most influential work grew out of her attempt to record the black experience. That novel,called Their Eyes Were Watching God,was about three generations of a family living in Eatonville. Her interesting representation of the southern dialect caused her Harlem Renaissance contemporaries to look down upon the work for what they saw as its spread of inaccurate patterns. Hurston,however,remained true to her project,believing that the accuracy of her representation would finally win over the political pressures her peers forced her to accept.
History has shown that Hurston was right. Modem critics admire her authentic(真實(shí)的) and skillful representation of the language as well as her realistic description of daily life in the early twentieth century. She is universally considered as one of the best writers of her era and ranked with Toni Morrison,Maya Angelou,and Alice Walker as one of the most important African-American writers of all time.
6. Hurston grew up in a town where .
A. a larger white society existed
B. all the four seasons were like spring
C. the black people could enjoy much freedom
D. the black people had no chance to get. an education
7. What happened to Hurston after she moved north?
A. She changed her political attitude.
B. She decided to give up her studies.
C. She developed an interest in literature.
D. She was warmly welcomed by the white.
8. At her times,Hurston's works were .
A. special in the way they were published
B. not popular with the general audience
C. mostly written in standard English
D. good examples of African history
9. What can we learn from Hurston's story?
A. It's easy to be wise after the event.
B. Where there is a will,there is a way.
C. A good beginning makes a good ending.
D. In time of danger,one's mind works fast.
10. What does the text mainly discuss?
A. The origins of a black cultural movement.
B. A very influential African-American novel.
C. A famous African-American female writer.
D. The struggle between the white and the black.

A
For decades,scientists thought the Tandayapa Andean toad (蟾蜍) was extinct. But a group of researchers recently came upon two living Tandayapa Andean toads in the foggy forests of Ecuador (South America) .
The rare,tiny brown toad was first discovered in 1970 in the Tandayapa Valley,located in Pichincha province in the northern part of Ecuador.
After finding one toad,biologists spent weeks looking for more. But they did not find any,and the toad was declared extinct almost as soon as it was discovered.
More than 40 years later,a team of scientists found not one,but two toads similar to the Tandayapa Andean. But these toads were not found in the same place. Instead,scientists found the twosome in the foggy forests of the neighboring Imbabura province.
“At first sight I couldn’t identify the species 一 it wasn't even on my radar (雷達(dá)) , since they hadn’t been seen in …years ,” Ryan Lynch,the lead scientist,told National Geographic. aBut I knew that it was something very rare."
On a return trip,biologists found many more specimens of the brown toad in the same area. Experts have declared that the species is not at all extinct.
The Tandayapa toad develops differently from other toads. Most toad babies start life as tadpoles,which have gills (鰓) and live in water. But Tandayapa toad babies,called toadlets,develop on land. These toadlets skip the tadpole stage entirely.
The Tandayapa's appearance is strange too. As toadlets,they are covered in patterns of copper and gold,with snaking white lines on their bellies. This pattern gets darker as the toads grow. By the time they become adults,they appear completely brown without a pattern and have white bumps (凸起) on their sides. Typical toads don't experience such extreme color and pattern changes.
Although scientists are excited about the reappearance of the Tandayapa toad,they still worry about the species' survival. Humans have been clearing much of the. forest where the toads live.
However,environmental groups are working to get these forest areas protected. Many hope that the rediscovery of the tiny brown Tandayapa toad may help make their case.
1. The Tandayapa Andean toad discovered in 1970 .
A. preferred living in pairs
B. got used to the dry weather
C. could be spotted everywhere in Ecuador
D. was considered the only one of this species
2. Ryan Lynch discovered Tandayapa Andean toads .
A. completely by chance
B. with the help of his radar
C. thanks to his return trip to Ecuador
D. in the same place the first toad was found
3. The Tandayapa Andean toads experience color changes when .
A. they are threatened
B. the weather changes
C. they are growing up
D. their habitats change
4. What's the present situation of the Tandayapa Andean toads?
A. They multiply rapidly.
B. They’ re still in danger.
C. They,re well protected.
D. They grow bigger than before.
5. What would be the best title for the text?
A. Living on land
B. Lost in the forest
C. Fighting for survival
D. Back from extinction

How successful
leaders spent their teenage years
I don't think I have ever before been compared with Bill Gates,Steve Jobs,etc. 36 But for what it is worth,I’11 give you some traits(品質(zhì)) that I think are common among most of these people.
Reading
Read a wide variety of books and articles that stretch(擴(kuò)展) your imagination. Don’t just read easy books (like Harry Potter) . 37 Those difficult texts can really stretch your mind.
Because most of the people mentioned grew up in a different era,they spent a big portion of their time just reading the encyclopedia. Many of them would eventually read every encyclopedia volume letter. These people had a strong need to learn new things.
Play-acting
At an early age,most of these people spent more time play-acting than others. Very few of these people spent their time playing organized sports ... they instead were in their bedroom, backyard,or nearby park playing by themselves. 38
Experimenting
It is amazing how many successful people lit things on fire,blew things up,caught and studied bugs,built bird nests,and more. 39 And they were the ones in charge of the experiment.
Creating vs. consuming
Watching wonderful movies,listening to music,etc. are all great ways to spend time. 40 Most of these successful people spent a large percentage of their time creating. They were building things,starting things,etc. This is really important.
A. Read things that challenge your thought.
B. Today it is harder to spend time creating.
C. They were letting their imagination run wild.
D. They were building,creating,viewing,and observing.
E. But they are passive — these are consuming functions.
F. Most of these people had parents that asked them to read less.
G. I am nowhere near as successful as most of the people on this list.
