题目内容

【题目】______ exciting our life will be in the future with so many wonderful invention!
A.What
B.How
C.What a
D.What an

【答案】B
【解析】句意:我们以后的生活中会有这么多奇妙的发明那是多么令人兴奋啊!感叹句一般是用来表示说话时的喜悦、惊讶等情感。英语感叹句常用"what"和"how"引导,"what"和"how"与所修饰的词置于句首,其它部分用陈述句语序。 由"what"引导的感叹句:"what"意为"多么"用作定语,修饰名词(被强调部分),单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是: what+(a/an)+adj.+n.+主语+谓语. 由"how"引导的感叹句:"how"意为"多么",用作状语,修饰形容词或副词(被强调部分)。如果修饰形容词,则句中的谓语动词用系动词;如果how修饰副词,则句中的谓语动词用行为动词,这类句子的结构形式是: How+adj.(adv.)+主语+谓语。所以选B。

【题目】阅读下面材料, 从每题所给的A, B, C, D四个选项中选出最佳选项。C
When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wild, everyone has his own way to protect himself. Even plants have their own ways to fight against their enemies.
Over millions of years, plants have developed their own way to protect themselves. Chemicals (化学物质) are used by plants to live. By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.
One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree's leaves, and the number of poisonous chemicals becomes more in the other leaves. "It's like the injured (受伤的) leaves telling the others to fight against the enemy together," he said.
The tree also sends messages to plants near it by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison in 10 minutes. Now, if an enemy eats too many of the trees' leaves, he will die.
Every kind of plant is good at producing special chemicals. Animals that feed on plants or grass, like rabbits, can safely eat the leaves of one tree, but they may be hurt by its neighbor.
In this way, plants have not only developed their own way to protect themselves, but also shared it with others. So it's impossible for a single animal to damage even a small area of forest.
