下列关于生物呼吸的叙述中,正确的是(  )

A.在陆地生活的动物都用肺呼吸

B.有的动物呼吸既不用鳃,也不用肺

C.细菌等微生物是不呼吸的

D.植物只在黑暗的环境中才需要呼吸

答案

A、陆地生活的动物一般都具有能在空气中呼吸的,位于身体内部的各种呼吸器官.如昆虫用气管呼吸,兔用肺. 故在陆地生活的动物都用肺呼吸的说法错误.

B、有的动物呼吸既不用鳃,也不用肺,比如蚯蚓用湿润的体表进行呼吸,故此项说法正确.

C、大多数微生物以有氧呼吸的方式呼吸,即使是酵母菌这样兼性厌氧型的,在有氧的情况下也是以有氧呼吸为主,只有少数的微生物进行无氧呼吸(如乳酸菌等).所以细菌等微生物是不呼吸的说法错误.

D、植物不论在有光和无光的环境中均能进行呼吸作用.故此项说法错误.

故选:B

完形填空

Directions: Read the following passage. Answer the questions according to the information given in the passage.

I’m not a fast reader and I don’t read as much as many other people, but reading is something I enjoy. It opens new worlds to me and widens my perspective(洞察力,眼力).

Recently I found Kobo,an online book store that allows me to buy e-books and read them on a device of my choice. I’m a girl living in Indonesia, where e-books are not available and I had to buy physical books from Amazon in the past. There are two problems with it:

Shipping cost. Since I live far away from the United States, it costs a lot to ship a book. Shipping costs almost as much as the book itself.

Shipping time. It takes about three weeks for the books to arrive through postal mail.

Now with Kobo, I can eliminate those two problems. Not only does it cost less time and money to get the books, but also I prefer to read e-books this way than reading physical books. Here are three reasons why:

I can easily bring the books everywhere. Since all the books are in my iPod touch, I can simply put the device into my pocket and bring it everywhere I go.

The size is smaller. The size of the iPod Touch is smaller than a physical book. This makes reading more convenient for me.

I can read in any position I want. The iPod has a light source, so I can read when I am in darkness. This means that I can read in practically any position and condition.

One more advantage I haven’t mentioned is space. Physical books take space, but e-books don’t.
