【正文】 the general quadratic equation ax2+bxy+cy2+dx+ey+f=0, where a, b,?…?, f are constants and a, b, and c are not all zero. In solid analytic geometry the orientation of a straight line is given not by one slope but by its direction cosines, λ, μ, and ν, the cosines of the angles the line makes with the x, y, and zaxes, respectively。 it was finally proved impossible in the late 19th cent. (see geometric problems of antiquity). In modern mathematics the circle is the basis for such theories as inversive geometry and certain nonEuclidean geometries. The circle figures significantly in many cultures. In religion and art it frequently symbolizes heaven, eternity, or the universe. 。 the glorification of the act of painting itself as a means of visual munication。 also called action painting and the New York school. It was the first important school in American painting to declare its independence from European styles and to influence the development of art abroad. Arshile Gorky first gave impetus to the movement. His paintings, derived at first from the art of Picasso, Mir243。 （略）（一定要自己寫） 作業(yè) 2 ( Units712)答案 第一部分 交際用語 C A D D D 第二部分 英語知識運(yùn)用 二、選擇填空 6.

When we make healthy habits a part of our everyday life, we are bound to keep healthy. 學(xué)習(xí)記錄卡 3（ Units 13～ 18） （ p2526） 學(xué)習(xí)過程： 輔導(dǎo)訂前完成的學(xué)習(xí)內(nèi)容： A、 √ 做教材中大部分練習(xí) B、 √ 熟悉生詞和詞組 C、 √ 將不懂的地方記錄下來 D、其他 輔導(dǎo)課上的學(xué)習(xí)任務(wù)： A、 √ 聽輔導(dǎo)教師講授 B、 √ 積極參與各項(xiàng)課堂教學(xué)話動 C、 √ 解決疑難問題 D、其他 輔導(dǎo)課后的學(xué)習(xí)內(nèi)容： A、完成剩余的練習(xí) B、 √ 復(fù)習(xí)主要語言點(diǎn) C、自己找一些練習(xí)題進(jìn)一步鞏固所學(xué)內(nèi)容 D、其他 希望輔導(dǎo)教師提供的幫助是： A、答疑解惑 √ B、系統(tǒng)歸納和講解 √ C、有針對性地講解重點(diǎn)、難點(diǎn) √ D、其他學(xué)習(xí)內(nèi)容： 學(xué)習(xí)方法 Units 13～ 18 中主要學(xué)習(xí)了哪些重要的語法項(xiàng)目？ 動名詞與動詞不定式、非限定性定語從句、將來完成時(shí)、現(xiàn)在進(jìn)行時(shí)的被動語態(tài)、現(xiàn)在完成時(shí)的被動語態(tài)、間接引語和間接引語、反意疑問句 這六個單元中我感覺最難或還沒有完全掌握的語言點(diǎn)是： 非限定性定語從句 這六個單元中我最喜歡的話題是： Describe towns 印象最深的 Cultural Notes是： The city 階段性學(xué)習(xí)體會 ：請總結(jié)一下你在這一階段的學(xué)習(xí)情況 。 我要在輔導(dǎo)課前將不理解的難點(diǎn)記錄下來，然后在輔導(dǎo)課上問同學(xué)或老師。你可以把這一階段你在學(xué)習(xí)中遇到的困難、困惑寫下來，也可以把你的建議想法寫下來跟老師和其他同學(xué)交流（略）（一定要自己寫） 作業(yè) 1（ Units16） 答案 學(xué) 習(xí) 計(jì) 劃 學(xué)習(xí)計(jì)劃表 在計(jì)劃要做的事情旁邊打勾 我每周用 5/6/7 小時(shí)用來完成教材練習(xí)。你可以把這一 階段你在學(xué)習(xí)中遇到的困難、困惑寫下來，也可以把你的建議想法寫下來跟老師和其他同學(xué)交流。s disease. abstract expressionism, movement of abstract painting that emerged in New York City during the mid1940s and attained singular prominence in American art in the following decade。 the harnessing of accidents that occurred during the process of painting。 a circle is circumscribed about a polygon if all the vertices of the polygon lie on the circumference. The length of the circumference C of a circle is equal to π (see pi) times twice the radius distance r, or C=2πr. The area A bounded by a circle is given by A=πr2. Greek geometry left many unsolved problems about circles, including the problem of squaring the circle, ., constructing a square with an area equal to that of a given circle, using only a straight edge and pass。 these satisfy the relationship λ2+μ2+ν2= 1. In the same way that the conic sections are studied in two dimensions, the 17 quadric surfaces, ., the ellipsoid, paraboloid, and elliptic paraboloid, are studied in solid analytic geometry in terms of the general equationax2+by2+cz2+dxy+exz+fyz+px+qy+rz+s=0. The methods of analytic geometry have been generalized to
