阅读理解。 Spider webs are one of the most fascinating examples of animal architecture. The most
beautiful and structurally ordered are the round webs. The main function of the web is to stop
and hold flying insects, long enough for the spider to catch them. In order to do so,the threads
of the web have to stand the forces from large and heavy insects as well as environmental forces
from wind and rain for at least a day in most cases.
The round web is found to have two main characteristics. The first is its geometry,which
consists of an outer frame and a central part from which threads radiate outward. Enclosed in
the frame are capture spirals winding round and round from the web center out to the frame.
The whole web is in tension and held in place by anchor threads,which connect the frame to the
surrounding plants or objects. The second and perhaps most important characteristic is the
material with which it is built. Spider silk is a kind of natural material that gives this lightweight
fiber a strength comparable to that of steel, while at the same time making it very elastic(有弹性的).
Two types of silk threads are used in the web. One is highly elastic and can stretch to almost twice
its original length before breaking and, for most types of spiders,is covered in glue. This type is
used in the capture spiral for catching and holding insects. The other is stiffer and stronger,and is
used for the radius,frames and anchor threads,which allows the web to stand forces and to keep
its structural strength through a wide range of environmental conditions.l. What does the word"so"in the first paragraph refer to?A. To catch and keep small creatures.
B. To find a good material for the web.
C. To make the webs beautiful and well ordered.
D. To make the threads long enough.2. Which of the following is used for catching and holding insects?A. The center of the web.
B. The capture spirals.
C. The anchor threads.
D. The radius.3. Which of the following correctly gives the names of the numbered threads in the picture?A. ①capture spiral ② radius
B. ①radius ② capture spiral
C. ①anchor thread ② frame thread
D. ①frame thread ② anchor thread4. Which of the following best describes the threads used in the capture spiral?A. Natural and lightweight.
B. Strong and stiff.
C. Smooth and elastic.
D. Strong,sticky and elastic.5. What is this passage mainly about?A. The wisdom of spiders.
B. The function of round spider webs.
C. The structure of round spider webs.
D. The challenges for spider webs.

阅读理解。     Squirrels often communicate with whistles, chirps and chucks, which sound like the word
"chuck". Whistles and chirps are like the sounds that many birds make. Now scientists have
translated some of their squirrel-speak.
     Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team
managed to record squirrels" alarm calls. The researchers studied the sounds and then played
them back to 60 wild squirrels, which the scientists approached individually with a video recorder
to capture(抓拍)their responses. Some squirrels lifted their heads up and became alert(警惕的).
Creatures that were more frightened simply ran for their lives and dived into caves.
     "In effect then, whistles that mix with chucks say "there"s an enemy of average threat that"s here",
and whistles without chucks say "there"s an enemy of seemingly average threat around here
somewhere", while pure chirps say, "I"m hiding here because there"s an immediate danger." " Hare
told Discovery News.
     Hare and some other researchers believe such sounds are part of an advanced language that
develops just as all other communication systems.
     Although squirrels risk their lives when they call out to warn others of threats, other squirrels
might admire this behavior, thus increasingly the caller"s social status, like humans who look up to
heroes. Hare added that other animals, such as birds, probably understand at least some squirrel
language, since they also may benefit from the alarm calls.
     In fact, another Canadian study found that deep-voiced, black-capped chickadees have their
own language too. According to certain research, there are a lot of tidings in chickadees" calls, such
as directing fellows" activities, keeping in contact between mates, and raising alarms.
     While chickadees and other birds are often welcomed into gardens by homeowners, squirrels
are frequently viewed as pests(害兽). Hare wishes a greater understanding of the complex social
lives and communication systems of squirrels will provide "hope that humans will gain a greater
appreciation and stop doing harm to these animals".1.The text mainly talks about       .A. the study on the language of squirrels
B. the comparison between squirrels and chickadees
C. the calling for the protection of squirrels
D. the ways for squirrels to escape from their enemies2.If a squirrel is in a very dangerous situation, it would probably make ____.A. whistles with chucks
B. pure chirps
C. whistles without chucks
D. repeated chucks3.The underlined word "tidings" in paragraph 6 probably means ____.A. difficulties
B. poises
C. messages
D. languages4.What can be learned from this text?A. Squirrels communicate with each other as humans do.
B. Some squirrels understand the recorded alarm calls.
C. Other animals also well understand the language of squirrels.
D. Birds such as chickadees don"t have their own language.

阅读理解。     Baby girls make their way directly for dolls as soon as they can crawl,while boys will head for cars,a
study has shown.The findings,the first to show differences in very young babies,suggest there is a
biological basis to their preferences.
     Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90
babies aged 9 months to 36 months.The babies were allowed to choose from seven toys.Some were
typically boys" toys-a car,a digger,a ball and a blue teddy.The rest were girls" toys: a pink teddy,a doll
and a cooking set.They were placed a meter away from the toys;and could pick whichever toy they liked
their choice and the amount of time they spent playing with each toy were recorded.
     Of the youngest children (9 to 14 months),girls spent significantly longer playing with the doll than
boys,and boys spent much more time with the car and ball than the girls did.Among the two and
three-year-olds,girls spent 50 percent of the time playing with the doll while only two boys briefly touched
it.The boys spent almost 90 percent of their time playing with cars,which the girls barely touched.There
was no link between the parents" view on which toys were more appropriate for boys or girls,and the
children"s choice.
     Dr Brenda Todd said,"Children of this age are already exposed to much socialization.Boys may be
given"toys that go"while girls get toys they can care for,which may help shape their preference . But these
findings agree with the former idea that children show natural interests in particular kinds of toys.There
could be a biological basis for their choices.Males through evolution have been adapted to prefer:
moving objects,probably through hunting instincts(本能),while girls prefer warmer colors such as pink,
the colour of a newborn baby."                                 1.Baby boys and girls have different toy preferences probably because____A. baby boys are much more active
B. baby girls like bright colours more
C. their parents treat them differently
D. there is a natural difference between them 2. Both baby boys and baby girls like to play with____ according to the study.A. a ball
B. a teddy
C. a car
D. a doll   3.What can we infer from Paragraph 3?A. Nine-month-old baby boys don"t play with dolls at all.
B. Two-year-old baby girls sometimes play with cars and balls.
C. The older the babies are,the more obvious their preference is.
D. Parents should teach their babies to share each other"s toys.4.What conclusion did Dr.Brenda Todd draw from the results of the study?A. Adults purposely influence their babies" preference.
B. Babies" preference isn"t affected by social surroundings.
C. Baby boys preferring to moving toys will be good at hunting.
D. Baby girls preferring warmer colors will be warm-hearted. 5.We may read this article in a______section of a newspaper.A. science
B. health
C. education
D. entertainment.
