空格

Hovercraft, or air-cushion vehicle, are unusual travel over land and water on a layer of air.

解释：空格前是句子的主谓语，空格后是谓语结构，空格处需要从句引导词及从句主语，只有D符合题意，in that是特殊的状语从句引导词，表原因

Just add at least two whitespaces at the opposite end of your text: Add two spaces on the left to align right, two spaces on the right to align left and two spaces at least at both ends for centered text.

只需要添加多余两个的空格在您需要对齐的方向的反向即可：如果需要右对齐，在左边添加两个空格；反之，则在右边添加。在两边均添加空格可以实现中间对齐。

Note that in the first example, one space between each column was added by the way print works: it always adds spaces between its arguments.

需要注意的是第一个例子里使用 print 时每两列之间有一个空格：它总是在参数之间加一个空格。

A space in a regular expression, by the way, matches a literal space in the target (this is unlike most programming languages or command-line tools, where a variable number of spaces separate keywords).

顺便说一下，正则表达式中的空格就匹配目标中字面上的空格(这和绝大部分编程语言或者命令行工具不同，因为它们都是使用空格来分隔关键词)。

B。 分析：思路特点：注意空格后句中的词语使用特点：空格后面连续两句都涉及到了"suspension bridge/吊桥"因此判断空格处出现对"吊桥"进行讲述的句子的可能性最大，但被选项中没有该词出现，注意到空格后的句子中出现了代词They，该词的出现表明前面有复数的名词与之相呼应，而且They内容是指"桥"，因此排除A，C和E， F（没有与They呼应的内容），所以答案是B。

A Some environmentalists are againstthe projecton biological grounds（on..grounds/on the grounds of..根据）.D They're what will keep the bridge fromgoing anywhere.F They will tip up the scales at 166, 500 tons – more than half the bridge's totalmass.Getting these cables up will be something. It is not just their length –totally 5.3 kilometers – but their weight.

F。 分析：思路特点：注意空格后句中的词语使用特点：空格前出现了their length， their weight，根据前句内容判断their指"these cables"，空格前句内容的重点在重量上， F具体提到了有关重量的数据166， 500 tons，因此F是答案。

b。 分析：思路特点：注重空格后句中的词语使用特点：空格后面连续两句都涉及到了"suspension bridge/吊桥"因此判定空格处出现对"吊桥"进行讲述的句子的可能性最大，但被选项中没有该词出现，注重到空格后的句子中出现了代词they，该词的出现表明前面有复数的名词与之相呼应，而且they内容是指"桥"，因此排除a，c和e， f（没有与they呼应的内容），所以答案是b。

Pushed by science, or what claims to be science, society is reclassifying what once were considered character flaws or moral failings as personality disorders akin to physical disabilities.正确选项: It is worrisome that society is medicalizing more and more behavioral problems, often defining as addictions what earlier, sterner generations explained as weakness of will.

第一层对应为：空格前句的diagnostic，选项中的medicalize以及空格后面的physical虽然不是近义词或同义词，但很明显它们属于同一范畴，属于医学范畴，因此是同一范畴词汇对应；第二层对应为：选项中的defining as（注意选项中有倒装结构，原结构应该是define…as…）与空格后的reclassifying…as…是近义词表达法，都是表示&归类为，定义为&；第三层对应为：选项中的weakness of will和空格后句中的character flaws是上下义词的关系，前者属于后者。

Ex: Sturgeons are prized for their blackish roe , which when salted and served as an appetizer is called caviar .

空格前为一完整句，且空格前最后一个字母为名词，即：S + Vt + n。那么空格中答案90%为定语从句。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
