This chapter is about how to move past using simple basic sentences into using compound sentences. When sentences are combined they give a natural flow and rhythm to your writing that using all short sentences doesn't create.

Compound sentences are created through coordination. Coordination is taking two or more independent clauses and putting them into the same sentence using either a conjunction or a semicolon or both.

The most important element to making coordinated sentences is to be certain that you are joining two independent clauses instead of clauses and phrases. In addition to studying the conjunctions, you will also study the punctuation patterns for compound sentences. This chapter will cover three different methods for combining sentences: using a coordinating conjunction, using a conjunctive adverb, or using just a semicolon. By the time you have completed this chapter you should be able to write sentences that varying in length so that your writing has a more flowing style.

A cracked smartphone screen's no good. But future phones may be sold with cracks built in—because a network of tiny cracks can actually toughen up a piece of glass.

The crack research team borrowed the concept from mother-of-pearl, the iridescent stuff in abalone shells. It's 3000 times stronger than the mineral it's made of, due to its jigsawlike construction.

Using a 3-D laser engraver—the tool used to make those glass trophies with a logo floating inside—the researchers carved cracks a few microns wide into glass slides, and filled the cracks with polyurethane. The resulting glass was 200 times tougher, because the microcracks dissipate energy, preventing larger cracks. The study is in the journal Nature Communications. [M. Mirkhalaf, A. Khayer Dastjerdi and F. Barthelat, Overcoming the brittleness of glass through bio-inspiration and micro-architecture]

The cracks in this study are visible—so, not suitable for a smartphone screen. But the researchers say it's possible to shrink them down to less than a micron wide, an imperceptible size. As to whether crack-proof screens are a good business model, well, how much are you willing to shell out for an unbreakable phone?

8月14日，北京奧運會女子個人射箭決賽在奧林匹克公園射箭場舉行。中國女子射箭隊員張娟娟一路過關斬將，最終以12箭110環-109環的成績險勝韓國選手樸成賢，最終喜獲中國射箭隊的第一個奧運會冠軍。

這是中國射箭在奧運會史上的第一枚金牌。這也是中國代表團在本屆奧運會上獲得的第21枚金牌。

張娟娟在這以前，先後遇到了“夢之隊”的選手朱賢貞和尹玉姬。尹玉姬是12箭世界記錄的保持者，她曾在射箭世界盃土耳其站的比賽上以12箭19環的驚人成績打破了當時的世界紀錄。但是張娟娟發揮了她優異的成績，以106-101和115-109成功普級，將兩位韓國選手打敗。

後來，張娟娟在決賽時再次遇到了韓國選手。這次是韓國女隊領軍人物樸成賢。

決賽開始了，樸成賢先射，9環。張娟娟以一個幾乎接近靶心的10環發起了攻擊。第2箭，樸成賢立刻射出了10環給予回敬，張娟娟這下似乎有一點緊張了，只射出來了7環。。三箭過後，樸成賢領先3環。第二組開始了，張娟娟在落後的情況下並不急躁也不緊張射出3個9環，而樸成賢則在前兩箭射出了8環。兩組射畢，張娟娟落後2環。第三組，張娟娟穩定心態射出兩個10環，她穩定的表現給了對手巨大的壓力，樸成賢發揮有些失常，可能是有些擔憂。以兩個9環一個8環丟掉了優勢。三組過後，張娟娟以1環的`優勢進入到了決賽最後一組箭的比賽。

最後一組開始了，大家的心“嘭嘭”直跳，都屏住了呼吸。第一箭，雙方都射出了10環，此時樸成賢似乎是感到了一股巨大的壓力，第二件，她只射出來了8環。而張娟娟則射出了9環的好成績。最後一箭了。樸成賢射出了10環，此時樸成賢12箭射完，109環。中國射箭歷史只看張娟娟這一箭了。無意，張娟娟這一箭決定的不止是冠軍金牌花落誰家。9環！場上比分，110-109.張娟娟憑藉這1環的優勢為中國又添一枚金牌。

自女子射箭項目在1984年列入奧運項目後，韓國選手已經在女子射箭個人比賽中連續六屆奪冠。此次韓國女隊更是將“七連冠”作為自己來參賽的目標。但是，張娟娟，她成為了韓國“夢之隊”的終結者。她一路過關斬將，連贏三名韓國高手，為中國奧運射箭史翻開了新的篇章。

此時此刻，全場的觀眾都興奮地跳了起來，我和媽媽臉上也露出了燦爛的笑容。我激動得在那兒亂蹦亂跳。經過許多年的練習，中國終於奪得了射箭首金，不止打敗了韓國6連冠的遙遠路程；也為上次雅典奧運會的一環之差報了仇！

她是我喜歡的運動員。因為她身上有我學習的更多地方。不服輸的精神；向上拼搏的信念；不受外界影響……這些都是我要向她學習的地方。但是我想：我從她身上看到的一切都是源於兩個字——夢想！有夢想去拼搏，就會有結果。

Motorcycles

nowadays, them are more and more motorcycles in streets. now and then. one or two molorcycles will come into your sight and your ears are filled with their noises. you are aware that motorcycles play a very important part in our modern life,. some people like to ride motorcycles and others dont.

some people like riding motorcycles. they think that motorcycles can run much faster than bicycles and as fast as cam though they are small in size. those who ride mo torcycles can save much of their time. moreover, riding fast is eciting.

other people dont like riding motorcycles. they think that riding motorcycles is very dangerous. there have been more motorcycle accidents in recent years. if you ride very frost, you will fail to leact properly when an emergency happens. the resuh is that you will be injured or even killed.

"Don＇t throw that plastic box away! It can be used to hold some tiny gadgets." "But we have already saved a lot!" "Give it to me. One day eventually U 11 find a suitable place for it!" More than once my grandpa stops me when I endeavor to discard some pieces of "junk" stealthily, and more than once his "eloquence"makes me give in and involuntarily put the "junk" in its "suitable place. "This is my grandpa, an old man who has experienced the sufferings of the bygones. Years of thrifty life has helped him develop a habit of preserving everything, everything he thinks is tries to fit them into some places. Surprisingly, these "junk" can always find their position and function fairly well,holding small things, bolstering a wooden structure on which plants can grow, optimizing my bicycle so that it can operate better......

But sometimes, some of these things are nasty. Grandpa also collects used clothes and socks. I seldom see him wearing new ones unless on an unusual occasion. When he is given some fashionable apparel, he will lay them in lethargy. And grandma is always arguing with him on this issue. In the meantime, he will present sets of adages of thrift to show her the importance of a provident people tend to the past century, China was ravaged a great older generation just could not forget about the arduous life they led at that they were accustomed to can always find its way in today＇s life they are X generation of us must neither blame nor laugh at them.

In the past 20 years China has experienced an alarming increase in teenage smoking: the number of boys who smoked rose from 6 percent in 1980 to 23 percent in 20xx, and during the same years, the number of girls who smoked increased as much as 15 times. The statistics look quite disturbing and cause people to ask why.

The factors for a great rise in teenage smoking are complex. Some attribute it to the increased standard of living which enables kids to have more pocket money, and others place the blame on cigarette advertising and the import of cigarettes, which give them easy access to Marlboros. Whatever the causes, only particular external circumstances have been examined. The factors, actually, are psychological as well as social. Most young people begin to smoke just out of curiosity: they have a strong desire to experience the pleasure of smoking which is forbidden to them. They also have a subconscious feeling that smoking will make them mature and tough and sophisticated. When they light up a cigarette, and produce puffs of smoke carelessly, they are under the illusion that they are growns-up instead of kids and that they are admired rather than rejected by society.

To help them get rid of such foolish ideas is the first step towards the effort to prevent children from starting to smoke, and then we may conduct a more extensive campaign to make them aware of the dreadful consequences of taking up the habit.
