雅思高分作文备考攻略

写作对于中国考生而言是比较难拿高分的一门考试，到底该如何做才能拿到高分呢?本文就为大家带来雅思高分作文备考攻略，包括写作要点，写作原则以及方法等，希望考生多多参考学习。 雅思高分作文的写作要点

要想写出一篇高分作文来，考生就要掌握三大写作要点，即涵盖题目所有要求，结构清楚合理以及词汇运用丰富、灵活。

无论是大作文还是小作文，对于题目中的要求考生没有做出回应的话，一定会被扣分，因为没有满足雅思写作评分标准第一项的要求。例如在小作文图表描述中，如果只是简单的罗列堆砌，不做任何分析、概括和比较的话，扣分是在所难免的。

结构清楚指的是一篇文章在整体上是由三大基本成分所组成的，即开头段、主体段与结尾段。开头与结尾要首尾呼应，主体段到底写几段就要根据具体题目而定，但是每一段主体段的首句必须有一个主题句，起到总领下文，提点中心的作用。下面再在进行用拓展句补充说明，以及结尾句进行小结。结构合理指的是论证结构合理，立场要鲜明。

词汇资源是雅思写作评分标准之一，具体体现在Accurateness(准确性)、Authentic

Vocabulary(地道词汇的使用)、Variety(词汇多样性)三个方面。换句话说，就是说考生不仅要掌握一定的词汇量，更要懂得灵活准确运用。忽略了任何一点都会影响得分。点击查看详细的雅思高分作文的写作要点

雅思高分作文的写作原则

除了雅思写作要点之外，考生还需遵循雅思写作高分的写作原则，共有四个，即长短句原则，主题句原则，一二三原则和多实少虚原则。

长短句原则意思是长句和短句相结合使用，而不是一味的追求长句难句或是全部都是简单句。长句和短句各有各的好处，长句可以使文章显得较复杂，有水平一些，短句可以起到简短精悍，画龙点睛的作用。考生要衡量其利弊之后再动笔写。

主题句的重要性相信很多考生都有所了解了，没有主题句的段落是不完整的，称不上一个完美的段落。因此，主体段的首句一定要是一个主题句来说明段落的核心内容，让考官一目了然。 第三个原则指考生写作文时要有条理，逻辑要清晰，如用一些表示逻辑的连接词First, Second，Third之类的，以便通过这些关键性的标签让文章更清楚。

最后一个原则强调的是考生的作文不要空话连篇，论据不充分等，也不要出现过多的较为空泛的词，比如nice就可以细化成generous, humorous之类的形容词。点击查看详细的雅思高分作文的写作原则

雅思高分作文实现的方法

取得雅思作文高分虽不是易事，但是考生可以通过“四化”来实现自己雅思写作高分的目标。“四化”具体指的是内容简单化，结构模式化，语言装饰化以及考前要强化。

雅思写作考试考察的重点是考生的英语语言表达能力，内容并不是重点考量的。因此，作文只需保证内容符合逻辑，言之有理，切题即可。考生千万不要把内容放在第一位，

强行塞进一些无关紧要的话语，更不要为了凑字而写一些重复的话，这样只会让文章显得啰嗦，无重点，自然会被就扣分。

不管是大作文还是小作文，考生在掌握了每一种题型之后要对其写作结构加以了解，这样拿过一个题目，才能快速想出按照什么结构去写这篇文章。

语言美化主要包括三点，语法方面的包装，句式多样化及注意文化的移入。语法知识点的夯实与正确应用是考生一定要用心准备的，这样才能避免语法错误的出现。句式多样化是另一个写作评分标准，因此，要想满则标准，一篇文章中应该有7-8个复杂句，前提是保证这些句子的正确使用。中英之间的文化差异也是值得考生注意的，如果随意使用一些不符合英文写作习惯或是让考官难以理解的句子来，可想而知一定会起反作用。

考前强化是说考生要从考官范文中挑选出符合自己水平的范文来，再不断仔细研究，抓住文章的构思，结构，句式等方面，使其成为自己的写作素材。另外，考生要坚持每天练习写作，发现自己的薄弱之处在哪里并加以改进。点击查看详细的雅思高分作文实现的方法

以上就是雅思高分作文备考攻略的详细内容，高分是每个考生都想要获得的，虽然拿到高分的过程是艰难的，但在考生的努力备考下，最终一定会实现。希望考生取得满意的雅思成绩，更多雅思备考经验我们将会陆续为大家更新。

As shown in Figure 1, the loading system consists of five forces and two couples. The two 64 N forces are parallel to each other and perpendicular to the bar. Moreover, the bar and these two forces are also in a plane which is parallel to the x-z plane. (a). Replace the loading system shown in Figure 1 by an equivalent force-couple system at point A. A diagram clearly showing the force-couple system is required. (b). Show that the resultant force is NOT perpendicular to the couple. Replace the force-couple system at A, by an equivalent wrench and state whether it is a positive or negative wrench. (c). Determine the magnitude of the moment of the wrench. (d). Find the coordinates of the point in the x-z place through which the line of action of the wrench passes.

An asymmetric bucket 1.20 m tall by 1.0 m wide as shown in Figure 2 is supported by pivots P and P′, which are vertically above the apex. Point O is the midpoint of P-P′, directly above point A (see Figure 2a). The bucket walls are non-uniform such that when empty, the centre of mass of the bucket is at point D on the line OA, 50.5 cm below point O (Figure 2b). The mass of the empty bucket is 650 kg. As the bucket fills, the centre of mass of the contents is at point E, which is NOT on line OA and as such the bucket tilts by an amount θ. Once the bucket reaches some critical angle θcrit, it will overflow at the corner C and will hold no more material than the critical volume Vcrit. If the bucket is less than full and it is desired for volume of material less than Vcrit to flow out, the bucket must be poured by attaching a cable at B and pulling vertically upward with a tension T. The density of water is ρwater=1000 kg-m-3 The density of molten iron is ρiron=7900 kg-m-3

(a) Find an expression for the volume of liquid in the bucket, V(θ), as it starts to pour as a

function of θ (see Figure 2C). Assume a straight line for the free surface of the liquid (water line).

(b) Find the position vector OE (Figure 2C) of the centre of mass of the liquid when the

bucket starts to pour, as a function of θ using the coordinate system with its origin at point O as shown,.

(c) Hence or otherwise; when the tension T in the pouring cable is zero,

I. find Vcrit and θcrit for water,

II. find Vcrit and θcrit for iron

(d) If the bucket contains iron and a tension, T, of 7700kN is required before the bucket

begins to pour, determine the volume of iron in the bucket at this moment.

(e) If the bucket containing water in part C)I, were taken to Mars (acceleration due to gravity

3.7ms-2), what would the critical volume be?

As shown in Figure 3, the frame ABCDE is supported by a pin at point A and a roller at point B. A distributed load described by function w = 4000??3+1600??2?900??+150 (N/m) is acting on member BCD, where x, in metres, starts from point C. Assuming that the weights of the bars are negligible, a) Replace the distributed load with an equivalent point load on member BCD and indicate the point of action. b) Draw the free body diagram of the whole frame and find the reactions at point A and B. c) Draw the free body diagrams for member BCD, DE and ACE and determine the forces acting on each of the members.

The ball-socket connected space truss structure shown in Figure 4 is part of a glider fuselage, and is supported by ball and socket joints at A, B and C. Forces applied at joints G, D and E are perpendicular to face/triangle DEG. The coordinates, in m, of various points are as listed in the table below. a) Find the reaction forces at A, B force.

As shown in Figure 5, a horizontal wire connects the object A and the inner circle of a wheel shaft. Another wire connects the outer circle of the wheel shaft and the object C through a pulley. The inner radius of the wheel shaft is 50 mm and the outer radius is 100 mm. The weight of the object A and the wheel shaft is 500 N and 1000 N respectively. The friction coefficient between the object A and the surface is 0.5 and the friction coefficient between the wheel shaft and the surface is 0.2. The friction between the rope and the wheels is negligible. The system is stationary. (a) Draw the free body diagram of the wheel shaft, object A and object C. (b) Find the maximum weight of object C can be put before the wheel shaft slips when θ = 30°, θ = 40° or θ = 50°.
