Step2 The use of subject-verb agreement
一、 概念
主谓一致是指主语和谓语在人称和数等方面的一致,当主语是不定代词或含有修饰语时,谓语动词的形式要依据主语所表达的单、复数概念而定,而不仅仅是取决于简单的外在形式。
二、具体用法
1.当主语被分数(百分数)、表示量的词汇等修饰时,谓语动词的形式要依据主语本身进行判断。
1)如果主语本身是可数名词单数或者不可数名词,则谓语动词要用单数形式;
2)如果主语是可数名词复数,或主语加上修饰语整体表达的是复数概念,那谓语动词要用复数形式。
a. About one-third of the books in the library are donated by students who graduated from the school.
b. Around 10 percent of the forest is destroyed each year.
c. A large number of people have applied for the job.
2. 当主语被不定代词修饰或主语本身是不定代词时,谓语动词的形式需要根据主语加上修饰语后整体表达的意义来进行判断。
a. Every means has been tried out without much result.
b. All of the work is done by me.
3. 当主语被否定词修饰或主语本身是否定词时,谓语动词一般用单数形式。
a. Nobody has got a ticket.
b. Nothing was available.

Internet of Things
What will be connected to the Internet of Things You. Your child. Your car, clothes, and house. The cook, the bread, the honey, the bees, and more. That's why some people call it the "Internet of Everything". By the year 2040, anything and everything that can be tagged with a wireless identifier will probably have one or more. By that time, these tiny, wireless electronic devices could do a lot more than just identify an object. They could relay data on size, shape, and location or receive instructions on what to do next.
These devices might be powered by light, motion, radio waves, or some other means. But they will not need to be plugged in or have batteries. Bigger devices control the smaller ones. Access to all those things in your reach will be through your phone or your virtual personal assistant.
The Internet of Things is already a thing. Right now it is in its early stages. In the future, when wireless tracking devices become cheap enough to spread, it will be a game-changer. Some industries are developing it because it gives them what they want most, including information about you, where you go, and what you do.
However, the Internet of Things could hit some bumps along the way. Tagging and tracking billions of things is a large and costly project. Technical issues for the wireless tagging of objects include size, durability, increasing transmission distance, and finding its precise location. Besides, privacy could be an issue. Who will be watching Who will have access to your information How will they use it Other concerns are terrorism, inequality, identity theft, and encroachment (侵入) on personal space.
