2018四级第三套作文答案【一】
春天， 万物复苏，小河水哗哗地顺流而下； 活泼机灵的小鸟们在枝头喳喳地纵情歌唱； 小草们神不知鬼不觉地从地下探出了脑袋，大地换上了绿色的新衣； 小野花们争先恐后地展示着自己的美丽； 一棵棵大树好像正在返老还童， 抽出嫩黄色的新芽；。年迈的`凤凰木也紧跟着春天的步伐， 吐出米粒大小的嫩叶， 就像刚出生的婴儿那般娇嫩。
夏天，太阳像一个火炉似地炙烤着地面。凤凰木的叶子早已变成了深绿色，枝条也向四周扩展了许多，变成了一把绿色的大伞。当太阳透过茂密的树叶筛下一束束金光时， 美丽的凤凰花绽开了一张张笑脸，好像给凤凰木披上了红色的霞衣。
秋天，凤凰树的叶子慢慢地变成了金黄色，在微风吹拂下纷纷飘落下来， 给地面铺上了一层厚厚的金色地毯。课间十分钟，我和小伙伴们在凤凰树下尽情地玩耍、嬉闹，甭提有多高兴了。
冬天，刺骨的寒风从耳边呼呼地刮过，古老的凤凰木褪去了繁华，仿佛一个弯着腰、知识渊博的老学者，正在讲述着她一百多年来的沧桑岁月， 并勉励我们克服各种困难、勤奋学习，成为对国家有贡献的人才。
这就是我们百年老校的百年古树---凤凰木。
2018四级第三套作文答案【二】
A constantly doing memory work
B making frequent adjustments
C going through specific training
D taking part in various mental activities
注：考第三段末句。
Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. The idea is not necessarily to learn to memorize enormous amounts of information, says James Fozard, associate director of the National Institute on Aging. Most of us dont need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness. Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
23. The findings of James and other scientists in their work _________.
A remain a theory to be further proved
B have been challenged by many other experts
C are practised by the researchers themselves
D have been generally accepted
注：第三段首句中的theory等同于findings。
2018四级第三套作文答案【三】
Dear Mary,
You said in your letter that many of your classmates wore fashionableclothes, but you couldn\'t afford them so you felt very depressed. There are dif-ferent views on people\'s clothes. The followings are my ideas:
Firstly, you shouldn\'t put too much emphasis on physical appearance.
Remember that the most important task for you today is to concentrate on yourstudies. No matter what you wear, you will really look your best when youcome out first in your examinations.
Secondly, you should understand that it is a fine virtue to live in fru-gality. Just as a famous saying goes, Frugality is the mother of virtue.
Since your family can\'t provide you with enough money to buy fashionableclothes, it is all the more necessary for you to try to lighten the financialburden of your family. And you will find the virtue of frugality benefit youa lot in your future life.
I hope you understand what I mean. Hope you will take a positive attitudetowards life and will be happy again when you read my letter.
Yours,
Anne
