1．Columbus Day is on the second Monday of October in the United States and some other countries around the world.For a long time，it was on October 12^th.It is named after Christopher Columbus，the Italian sailor who led the Spanish ships to discover new lands in 1492.There is even a child's poem remembering the date.It reads， "In 1492 Columbus Sailed the Ocean Blue." Some people say Columbus "discovered" America，although not everyone agrees with this.
   Columbus Day has been a federal holiday（聯(lián)邦假日）since 1937.Government offices，schools，and post offices are closed on this day.Many Italians take the day as a day to celebrate their own ethnic heritage（民族文化遺產(chǎn)）.Major cities，like New York City and San Francisco，host large parades.
   Not everyone thinks Christopher Columbus should be honored.Some states like South Dakota do not like the holiday at all.Instead，they call the day Native American Day.In Hawaii the holiday is also known as Discoverer's Day.This is because European arrival in North America meant the loss of land and lives for many native people.Many people hold protests （抗議）on this day to remember the Native Americans that were killed as a result of the European arrival.

2．There are two special days for parents in America.One is Mother's Day on（1） second Sunday of May，and the other is Father's Day on the（2） （three） Sunday of June.On these two days，（3） （America） children often give gifts to their parents or take them out（4） lunch or dinner.Common gifts are flowers and cards for（5） （mother） and shirts or ties for fathers.It is（6） （become） more and（7） （much） popular to celebrate Mother's Day and Father's Day in China.Chinese children also give some little gifts to their parents，（8） have dinner with parents.（9） （Actual），there are many ways（10） （show） our love.We don't have to spend a lot of money.It is a good idea to help parents to do something instead.

3．You might have noticed that sometimes，when you're playing mobile games or taking a video call，the picture suddenly freezes （卡頓） because the network speed is too slow.When you try to download a movie on your phone，it seems to take forever.
   These annoying things will soon become a thing of the past，as China just issued commercial licenses（發(fā)放商用牌照） for 5 G networks on June 6.This means that China's telecommunications （電信） companies will be able to offer 5 G network speeds for mobile phone users.
   The "G" in "5 G" stands for generation （of mobile network technology）.1 G let us talk to each other，2 G let us send messages，3 G gave us mobile data and internet，and 4 G made all of these things faster.So what will 5 G bring？
   First of all，5 G is so fast that it will allow you to download an entire HD movie in seconds.The delay（延時(shí)） between sending and receiving data will be shortened.Now，4 G takes about 100 to 200 milliseconds，while humans have a reaction time of about 200 to 300 milliseconds.But 5 G will get the delay down to 1 millisecond or less，which is almost real-time.
   Because of this increase in speed，it will be possible to create and use new kinds of technology.Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay.Self-driving cars will be able to drive more safely because they can smoothly communicate with each other，traffic lights and road sensors（傳感器）.
   5 G also makes the internet of things （IOT，物聯(lián)網(wǎng)） possible.IOT is a large network that connects nearly everything.For example，your toaster （烤面包機(jī)） might be able to automatically （自動） start making your breakfast after your alarm clock rings.And your sprinkler （灑水器） could know when to water your grass by sensing the air.
   All in all，5 G will shape every type of technology that it touches.And you won't have to wait too long for that to happen.
（1）How does the writer show that 5 G is fast？
A.By giving examples.
B.By telling a story.
C.By comparing numbers.
D.By giving opinions.
（2）What is the writer's purpose of writing the first paragraph？
A.To show that the network speed now is too slow.
B.To show that these things are annoy things.
C.To show that we usually face annoy things in the daily life.
D.To show that we usually can't download things quickly.
（3）Which of the following statements is TRUE according to the passage？
A.2 G lets us talk to each other.
B.5 G is so fast without any delay.
C.Self-driving cars can be able to drive completely safely.
D.The sprinkler could know when to water your grass.
（4）What can be inferred （推測） from the last paragraph？
A.Every type of technology will be influenced by 5 G.
B.It won't take too long to see 5 G influences technology it touches.
C.We need to wait for a long time to see 5 G shapes technology it touches.
D.Different types of technology will be shaped by 5 G at the same time.
