If you are one of those who want to know how to increase your vocabulary, there are some ways you may find useful. In fact, it is not that difficult to learn new words, but to remember them for a lifetime seems not to be so easy.

To make it easier, you can try word associations(联想). Try to find a connection between a new word and things or people you know. For example, if your neighbour is an unselfish person who cares about the needs of other people, think about this person every time you see the word, and very soon you'll start actively using it.

Try to use the words you learn as often as possible. Perhaps you are not sure which situations they should be used in, or whether you pronounce(发音) them correctly, but practice is the best way to understand that. It is not enough to find out the meaning of a word. You should hammer (敲打) it into your mind by using it in actual conversations in everyday life.

Also, it may be helpful to know the meaning of the word roots, prefixes (前缀) and suffixes (后缀), especially if they have a Greek or Latin origin(起源). Even if you meet a long unfamiliar word, it will be easy to know its meaning if you know the general meaning of its parts.  For example, if you see the word "philanthropy", it won't be difficult to surmise what it means if you know that "anthropo" means "human" and "philo" means "loving". Not only can ancient Greek and Latin be helpful, but a number of modern languages as well. So, if you speak French,  Italian, Spanish or Portuguese, guess the meaning of an unfamiliar English word if it sounds like  a word from another language you know.

古诗词默写(7分)

小题1:阅读诗歌就是感悟诗人的私人情感。秋日里,王绩在“树树皆秋色, ① ”中流露出孤独抑郁的心绪;孟浩然在“ ② ,北风江上寒”中勾起乘船返乡的念头;梅尧臣在“霜落熊升树,  ③ ”抒写山行的勃勃兴致;刘禹锡在“ ④ ,便引诗情到碧霄”中表达豪迈乐观的情怀……

小题2:思乡是诗歌的一个重要主题,孟浩然的《早寒江上有怀》中有“乡泪客中尽, ⑤ 。”直接表达思归不得的伤感;崔颢的《黄鹤楼》中有“晴川历历汉阳树, ⑥ ”。以苍茫之景烘托思乡之情;李白的《渡荆门送别》中写得更是新鲜,“ ⑦ ,万里送行舟。”以故乡之水的恋恋不舍,来凸显自己对故乡的思念,令人不禁叫绝。
