I Man Asks T Much Frm Nature.
What causes excessive cutting f trees? Why are we exhausting frests?
Because we human beingsuse wd t build huses and bridges; we use wd tmake paper; we use wd t make furniture and guns, and chpsticks.
Wd is a necessity in ur life. It will be terrible if we use them up ne day.
Man as a species thrives in the wrld, and we need space fr further develpment.
In sme cuntries with lng cast lines but shrt f flat grund, the gvernment build lng dikes t make land ut f sea.
We tear up seas and get mre land, but the after-effects are away beynd ur cntrl.
I What If We Stp Damages t Nature?
What if we stp excessive cutting f trees and using up wds? What if we decrease ur need fr wd furniture?
We will preserve the beauty f green muntains and grassland. Rare animals will be prtected with their habitats being cnserved s that peple f the future generatins may see them alive in the wild.
Let’s d it.
II Identify beauty in nature.
The sun sets the sky aflame with its last strive at dusk. The water is painted with burning red. What a magnificent gd-bye!
Snw cvers the Muntains far away. Snw presses the branches nearby lw. Out there the castlein wnderland seems t grw.
Rainbw crsses the sky high abve, Like a bridge f clrs inviting yu; What mysteries it carries , wh knws?
The ftsteps f fallare appraching, Trees welcme it with clrful leaves. Nature is a master fphantasy, isn’t it?
Daffdils quietly blm in the grassland, A glw f sunlightsftly tuch its head. Spring slips int the frest with its seasnal hell.
Cmprehensin Plus
When it’s sunny and Bright utside, we are cheerful inside.
When it’s cludy and raining utside, we ften feel glmy.
The starry night and the mnlight make us feel rmantic.
Let’s d it.
When we see leaves budding trees,
When a timid flwerpushes thrugh the frzen grund,
We smell new hpe iscming with spring.
Questin Time
1. Why des the authr say “we are damaging things s fast and they will sn be away beynd repair.”
Peple are destrying nature and using up natural resurces at such a fast speed that in the near future, natural balance wuld be cllapsed and hard t restre.
III Answer the fllwing questins.
2. What might be the reasns why future generatins “will be paupers when it cmes t the fferings f natural wrld”?
If peple d nt stp destrying the natural beauty, if peple keep n using up natural resurces, the balance f nature will be seriusly damaged that nature will prduce n mre beauty and n mre resurces fr the future generatins.
3. D yu think the authr is calling n us t preserve nature r t appreciate nature? Why?
I think the authr is calling n us t preserve nature. Encuraging us t appreciate nature is t warn peple that the beauty f nature is disappearing. And we shall d smething t preserve the beauty. I think this is the message f the text.
4. “Nature is an intrinsic part f ur lives.” What des this sentence mean?
It means that nature is an inbrn part f human life; nature and man are inseparable. If we are destrying nature, we are actually destrying part f urselves. In turn, if we are preserving nature, we are prtecting part f urselves.

Written in March By Wrdswrth
The cck is crwing,The stream is flwing，The small birds twitter，The lake dth glitter，The green fields sleep in the sun;The ldest and yungestAre at wrk with the strngest;The cattle are grazing，，Their heads never raising; There are frty feeding like ne!
Like an army defeatedThe snw hath retreated，，And nw dth fare illOn the tp f the bare hill;;The plughby is whping--ann--annThere's jy in the muntains;There's life in the funtains，Small cluds are sailing，Blue sky prevailing，The rain is ver and gne.
Read the pem and fill in the table belw.
green fields
wrking, happy
rain, gne
light-hearted
Interpreting “Written in March”
The pem is written in a very delighted tne. The creatures in march awakes t welcme spring. Animals like cck, birds and cattle are busy wrking and eating; stream and lake wake up while green fields still are waiting. Snw has melted away; muntains and funtains are all in jy; the sky is blue and bright; the rain is gne and ver. Nature brings us a beautiful and happy March.
