二、普通阅读
Leaves are nature’s food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide (CO2) from the air. Plants use sunlight to turn water and CO2 into glucose. Glucose is a kind of sugar. Plants use glucose as food for energy (f&ft) to grow. The way plants turn water and CO2 into glucose is called photosynthesis. That means "putting together with light.” A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is green. It gives plants their green color.
As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter.During winter, there is not enough light or water for photosynthesis. The trees will rest, and live on the food they have stored during the summer. They begin to close their food—making factories. The green chlorophyll disappears from the leaves. Then, we begin to see yellow and orange colors. A few of these colors stay in the leaves all the time. We just can’t see them in the summer, because they are covered up by the green chlorophyll.
Red and purple colours we see in leaves are made mostly in the autumn. In some trees, like maples(枫树)，glucose is stored in the leaves after hotosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into red. The brown color of trees like oaks(橡树) is made from wastes left in the leaves.

答案
一、选词短文填空
Keys: 1. owners 2. heard 3. from 4. used 5. idea
二、单选
1. B 解析：一般说来，序数词如first,second等前面要加定冠词the，但是，表示“又一”，“再一”时，序数词前加不定冠词（a an）,是 a second,a third的形式。本题翻译为，王平很擅长英语，他决定再学一门外语，再一 ，又一，用a second.
2.A 解析：many a +可数名词单数，谓语也用单数，但意思翻译为许多的。C选项没有这种用法，D中student要加s，而且如果选D，题干中的动词用复数，是have而不是has.
3.D 解析：价格的提问方法1，what is the price? 2.how much is it ?,两者千万不要混淆。
4.B 解析：主从句时态要一致，when后是过去时，排除AC，family这里指的是家人，复数，选B。
5.D 解析：过去完成时的时间标志，by the end of last year.
6.A 解析：情景问答，回答是我在宾馆当服务员，可知，选A。
7.A 解析：turn on/off应用于有开关物品的开关.open、close指其他物品开关，开收音机，有开关用turn on /off。从题意看，太吵了，所以是关掉。
8.C 解析： You’d better的用法是 You’d better do / You’d better not do,排除AD,后空用副词修饰receive.
9. B 解析：词意辨析，angry with生气 B. pleased with因、高兴 C. afraid of害怕 D. sorry for为、抱歉
10.C 解析：首先，后面一空，was 是be 动词的过去式，be 要和形容词，名词等搭配，排除AB.此题成功可以表示为，successful/a success.
