A．我们食用的番茄是由子房发育来的
B．我们食用的苹果主要部分是由受精卵发育来的
C．豆腐主要是由大豆种子的子叶加工来的

A、我们吃番茄使用的是它的果实，由上面的分析可知其是由受精后的子房发育来的．正确不合题意．

故选：B
第二卷 非选择题（共41分） 第四部分：任务型阅读（共10小题；每小题1分，满分10分） 请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。 注意：每空限填1个单词 In today’s society, everyone is busy and running at a fast pace each day. It does not matter what the reason is; your time is precious and needs to be managed effectively. You need cheap meal ideas that help you save your time and money and still provide a healthy and nutritious (有营养的) dinner for you and your family. The fast food makers know we have little time and use this very thing to make themselves successful. The idea of coming home after a long day at work and cooking for four or five people is not something we look forward to. This is why they offer you cheap food that requires no cooking, no cleaning, and only 25 minutes to pick up. But eating so much fast food will cause body fatness and fast food is not nutritious, so it’s not the healthiest choice to consider. There are some very cheap meal ideas that take almost no time to prepare and will make coming home for a good meal more enjoyable. The first cheap meal idea includes meat, vegetables and rice all in one dish. Not only is this a cheap meal idea, but it is fast since it can be made in only 20 minutes. You can quickly make some pancakes and scrambled eggs (摊鸡蛋) for the family in about 30 minutes. If you think it is strange to eat breakfast food for dinner, consider how the same foods give you what you need to go through an entire day. Another cheap meal idea to try is a “macaroni (通心粉) and cheese with meat” dish, which only takes around 20 minutes to cook. If you are interested in these cheap meal ideas, you’re welcome to visit our website for details. When you fix one of these or other cheap meal ideas at home, you are taking time out of your busy day to treat yourself and your family in a special way. Choosing fast and cheap food
