1．Happy Campers Summer Retreat
As a parent，your child's health and happiness are the most important things to you，which can be difficult to achieve.The Happy Campers Summer Retreat was developed to help parents with this challenge.
Founded in 1998 by Michael Gibson，our summer camp is open to children during the holidays，from May to September.We look after lots of children every single year.Our camp is based in the Colorado Mountains，and it offers a lot of different activities for children.
Our program helps improve：
? Physical fitness
? Problem-solving skills
? Social skills
? Sports ability and experience
The Happy Campers Summer Retreat can benefit all children.Some children are good at school，but rarely active.Our program will help encourage an interest in sports.Other children are mainly interested in sports.These children will not only play sports，but will also learn new skills，such as teamwork skills，social skills，and communication skills.Children will also have the chance to try new activities.Our program is designed to help develop a complete and fully active child.
At very affordable prices，our program is available to any family in America.Your child's stay can be as short as a week or as long as six weeks.
Why not call us today or click here to join our camp？Take action now and give your child this great chance!

2．As global temperatures rise，trees around the world are experiencing longer growing seasons，sometimes as much as three extra weeks a year.All that time helps trees grow faster.For the past 100 years，trees have been experiencing fast growth in mild areas from Maryland to Finland，to Central Europe，where the growth rate of some trees has even sped up by nearly 77% since 1870.Supposing wood were just as strong today，those gains would mean more wood for building，burning，and storing carbon captured from the atmosphere.But is wood really as dense（茂密的） as it used to be？
Hans Pretzsch，a forest scientist at the Technical University of Munich in Germany，and his colleagues wanted to find an answer.They carried out a study of the forests of Central Europe.They started with small pieces of experimental land in southern Germany，some of which have been continuously monitored since 1870.Pretzsch and his team took core samples （樣品） from the trees — which included Norway spruce，sessile oak，European beech，and Scots pine — and analyzed the tree rings using a high-frequency probe.
They found that in all four species，wood density had decreased by 8% to 12%. "We expected a trend of the wood density like this，but not such a strong and significant decrease，" Pretzsch says.Increasing temperatures，and the faster growth they spur，probably account for some of the drop.Another factor，Pretzsch says，is more nitrogen in the soil from agricultural fertilizer and vehicle exhaust.Previous studies have linked increased fertilizer use to decreased wood density.Above all，the study suggests that the higher temperatures — combined with pollution from car exhaust and farms — are making wood weaker，resulting in trees that break more easily and wood that is less durable.
"I am getting worried，" says Richard Houghton，an ecologist at the Woods Hole Research Center in Falmouth，Massachusetts，who was not part of the new study.As the density of the samples dropped，so did their carbon content.That means forests may suffer more damage from storms and may be less efficient at soaking up（吸收） the greenhouse gas carbon dioxide （CO2） than scientists think，Houghton says.
（1）Paragraph 1 is written to.
A．prove an idea
B．introduce the topic
C．give an example
D．describe a fact
（2）What does the study show？
A．Farming slows trees' growth.
B．More areas are covered with forests.
C．Climate warming changes the quality of wood.
D．Pollution leads to higher temperatures.
（3）What does Richard Houghton mean？
A．Great loss might be caused.
B．Storm damage can be prevented.
C．The size of forests might be increased.
D．Less greenhouse gases can be sent out.
（4）What is the best title for the passage？
A．We only have one earth
B．Trees — our best friends
C．The influence of climate change
D．Trees are growing faster，but weaker組卷：14引用：1難度：0.5 -
3．California has lost half its big trees since the 1930s，according to a study to be published Tuesday and climate change seems to be a major factor（因素）.
The number of trees larger than two feet across has declined by 50 percent on more than 46，000 square miles of California forests，the new study finds.No area was spared or unaffected，from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles.In the Sierra high country，the number of big trees has fallen by more than 55 percent；in parts of southern California the decline was nearly 75 percent.
Many factors contributed to the decline，said Patrick McIntyre，an ecologist who was the lead author of the study.Woodcutters targeted big trees.Housing development pushed into the woods.Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources（資源）.
But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010，McIntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.
The loss of big trees was greatest in areas where trees had suffered the greatest water shortage.The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed，taking into account such things as rainfall，air temperature，dampness of soil，and the timing of snowmelt（融雪）.
Since the 1930s，McIntyre said，the biggest factors driving up water stress in the state have been rising temperatures，which cause trees to lose more water to the air，and earlier snowmelt，which reduces the water supply available to trees during the dry season.
（1）What is the second paragraph mainly about？
A．The seriousness of big-tree loss in California.
B．The increasing variety of California big trees.
C．The distribution of big trees in California forests.
D．The influence of farming on big trees in California.
（2）Which of the following is well-intentioned but may be bad for big trees？
A．Ecological studies of forests.
B．Banning woodcutting.
C．Limiting housing development.
D．Fire control measures.
（3）What is a major cause of the water shortage according to McIntyre？
A．Inadequate snowmelt.
B．A longer dry season.
C．A warmer climate.
D．Dampness of the air.
（4）What can be a suitable title for the text？
A．California's Forests：Where Have All the Big Trees Gone？
B．Cutting of Big Trees to Be Prohibited in California Soon
C．Why Are the Big Trees Important to California Forests？
D．Patrick McIntyre：Grow More Big Trees in California組卷：20引用：1難度：0.5

9．A cactus （仙人掌） stood all alone in the desert，wondering why it was stuck in the middle of the desert. "I do nothing but stand here all day，" it sighed. "What use do I have？I am the ugliest plant in the desert.My spines （刺） are thick，my leaves are tough，and my skin is uneven.I can't offer shade or juice to the passing travellers.I don't see that I am of any use at all." All it did was stand in the sun day after day，growing taller and fatter.Its spines grew longer and its leaves grew tougher.It truly was strange-looking.
"I wish I could do something useful，" it signed.By day，hawks （鷹） circled high overhead，and the cactus called， "What can I do with my life？" Whether they heard or not，the hawks flew away.At night the moon floated into the sky and cast its pale light on the desert floor. "What can I do with my life？" the cactus called.The moon only stared coldly as it continued its course.
A lizard （蜥蜴） passed by，leaving a little trail in the sand with its tail. "What worthy deed can I do？" the cactus called. "You？" the lizard smiled，pausing a moment. "You can do something.Just wait for the right moment.The hawks circle their ways overhead，making beautiful patterns for us all to admire.The moon hangs high like a lantern at night，so we can see our ways home to our loved ones.Even I，the lowly lizard，have something to do.I decorate the sands with these beautiful trails as I pull my tail along.And you，you will show us your beauty some day."
Paragraph 1：
It went on year after year，and the cactus grew old.

Paragraph 2：
The desert hadn't known such a flower of it.
