關於藍色蜜蜂的英語閱讀
⑴ 學校老師要求用的一個APP,logo是一個綠色的蜜蜂,裡面就是有一些英語閱讀競賽要你做,請問那個
app是朔料包裝,logo是商標
⑵ 求一篇關於蜜蜂與農業的英文閱讀,第一段有15。急求!
蜜蜂其實對農業生產不是太重要,比如我們的主食是風媒傳粉的,小麥,玉米,水稻都是如此;我們的蔬菜主要是莖葉為主,瓜果豆類也有很多是自花授粉的;其三,蜜蜂的位置可以被其他昆蟲所替代,蛾子,蝴蝶,食蚜蠅啥的可以來填充空缺.事實也基本如此,蜜蜂不會影響到生活必需品,但是必定會影響到很多我們熟悉的東西.1.生產成本,實際上,人工授粉的成本遠比蜜蜂自然授粉的要高,至少,蘋果,梨,桃子這些水果還是需要蜜蜂的,另外,葫蘆科的單性的花朵更是需要蜜蜂.所以,人工授粉是可以解決問題,只是要花錢,人工成本低廉的時代已經過去了.2.我相信蜜蜂可以被替代,但是替代的過程會很長.畢竟,花朵和昆蟲的匹配是數百萬年演化的結果,低效率的花朵終究會淘汰的,所以,花朵依然是花朵.也許,火龍果就成了大宗水果了,食蜜鼠是它們主要的傳粉者.3.不經過授粉也能結果的水果也在培育過程中,比如香蕉,這個完全可以自行結果,而部分品種的火龍果可以自花授粉了.所以,農業生產似乎並不依賴於蜜蜂.這樣看來,倒是那些依賴蜜蜂傳粉的野生植物面臨更大的風險,但是一對一的情況比較少,所以我相信整個植物界還是會運行下去的.只是我們的餐桌上少了點蜂蜜.
In fact, the bees for agricultural proction is not too important, such as our staple food is anemophily, wheat, corn and rice are so; our vegetable is mainly stems and leaves, fruits and beans, there is also a lot of self pollination of bees; third, the position can be replaced by other insects, moths, butterflies, can to fill the vacancy of syrphids. What facts are basically the same, the bees do not affect the necessities of life, but it can affect many things we are familiar with the proction cost of.1., in fact, the cost of artificial pollination than natural bee pollinated by high, at least, apple, pear, peach and fruit still need these bees the simplicity of the Cucurbitaceae, flowers is the need for artificial pollination bees. So, it can solve the problem, only to spend money, low labor costs, the time has passed.2. I believe that bees can be replaced, but instead The process will be very long. After all, flowers and insects is millions of years of evolution, so the low efficiency will be eliminated, the flowers, flowers are still flowers. Perhaps, pitaya became the bulk of the fruit, the honey rat is their main pollinators.3. without pollination can result in fruit also in the process of cultivation, such as banana, the results can be completely, and some varieties of Pitaya can be self pollinated. Therefore, agricultural proction does not seem to depend on bees. It seems that it is the wild plant relies on bee pollination on more risk, but less of a situation so I believe the whole plant will still run down. But we have little honey on the table.
