On Tuesday, Apple's CEO Tim Cook announced the Apple Watch. The new smart device, which is worn on the wrist, just like a normal watch, can do all the things a cell phone does--and more.
At $349, the Apple Watch is expensive. Some experts doubt that they will become as successful as smartphones. It does seem likely, though, that the device will open yet another door in personal computing. The watch is the smartest computer yet. It taps you on the wrist whenever a new message comes in. It prepares answers to questions you receive from friends. It reminds you where you parked your car. It tracks your health. It even allows you to send your heartbeat to others.
When it goes on sale early next year, it will be Apple's first item in a new category of technology--wearable computers. If the Apple Watch becomes popular, it will change the way the world interacts with computers. People may depend on the smart jewelry even more than they already depend on their phones. "It might not only be a game changer for Apple, but for the entire industry." says technology expert Daniel Ives. "A lot of major technology players around the globe are taking notes on what Apple is trying to do here."
The Apple watch is specially designed for a smaller device. An entire computer fits onto a single chip(芯片). Users will be able to scroll(滚屏)just like they would do on an iPhone. It will have a built-in speaker for alarms that users can both hear and feel. Pressing the side button brings up contacts so you can communicate with people quickly and easily. Apple Watch also introduces health and fitness apps that can help people lead healthier lives. The built- in heart rate sensor (传感器) and GPS will track calories burned and workouts.
According to Matt Vella, a writer for TIME magazine, the watch is the most exciting device since the iPad. After actually trying the watch, he says, “It sits on the wrist very naturally. You could easily forget you are wearing the Apple Watch, and you will."
1.What does the underlined sentence in the third paragraph imply?
A.Apple Watch will include many new games.
B.Many game developers will pay attention to Apple Watch.
C.Apple plays an important part in the personal computing field.
D.Apple Watch will greatly influence the personal computing field.
2.The fourth paragraph mainly tells us .
A.how the Apple Watch works
B.the small size of the Apple Watch
C.what information we can get from the Apple Watch
D.the difference between the Apple Watch and the iPhone
3.The side button on the Apple Watch is used to .
A.sound the alarm B.adjust the built-in speaker
C.build the man-machine communication D.make the health and fitness apps start working
4.What is Matt Vella's attitude towards the Apple Watch?

In recent years, there has been a steady attack on salt from the doctors: salt is bad for you—regardless of your health. Politicians also got aboard. “There is a direct relationship,” US Congressman Neal Smith said, “between the amount of sodium(钠) a person consumes and heart disease, circulatory(循环的) disorders, stroke and even early death.”
Frightening, if true! But many doctors and medical researchers are now beginning to feel the salt scare has gone too far. “All these remarks and cry about salt is unnecessary,” Dr. Dustan insists. “For most of us it probably does not make much difference how much salt we eat.” Dustan’s most recent short-term study of 150 people showed that those with normal blood pressure experienced no change at all when placed on an extremely low-salt diet, or later when salt was reintroduced. Of the hypertensive(高血压的) patients, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to previous level when salt was reintroduced.
“An adequate to somewhat excessive(过度的) salt intake has probably saved many more lives than it has cost in the general population,” said Dr. John H Laragh. “So an opinion that the whole population should avoid salt makes no sense.”
Medical experts agree that everyone should practice reasonable “moderation”(节制) in salt consumption. For the average person, a moderate amount might run from four to ten grams a day, or roughly 1/2 to 1/3 teaspoons. One to two grams of salt would come from the natural sodium in food. The rest would be added in processing, preparation or at the table.
“Na is not your enemy,” says Comek’s Dr. Laragh. “Salt is the No.1 natural component of all human tissue, and the idea that you do not need it is wrong. Unless your doctor has proven that you have a salt-related health problem, there is no reason to give it up.”
1.Why is salt attacked by doctors and politicians?
A. It’s unnecessary.
B. It does no good to human health..
C. It is hated by most people.
D. It will surely lead to heart disease and circulatory disorders.
2.From Dr. Dustan’s study in Paragraph 2 we can infer that _____.
A．a low-salt diet may be good to some patients
B．the amount of salt intake has nothing to do with one’s blood pressure
C．the reduction of salt intake can completely cure a hypertensive patient
D．an extremely low-salt diet makes no difference to anyone
3.In the 3rd paragraph, Dr. Laragh implied that _____.
A．people should not be afraid of taking much excessive salt
B．doctors should not always advise people to avoid salt
C．an adequate to somewhat excessive salt intake is suggested to ill people
D．excessive salt intake has killed some patients in the general population
4.What is the experts’ advice for average people on salt consumption?
A．They should increase salt intake through sodium pills.
B．They should avoid salt as often as possible.
C．They should consume 1/2 to 1/3 teaspoons of salt a day.
D．They needn’t care about how much salt they consume.

The United States is one of the few countries in the world that has an official day on which fathers are honored by their children．On the third Sunday in June, fathers all across the United States are given presents, treated to dinner or otherwise made to feel special．
However, the idea for creating a day for children to honor their fathers began in Spokane, Washington．A woman by the name of Sonora Smart Dodd thought of the idea for Father’s Day while listening to a Mother’s Day sermon in 1909．Having been raised by her father, Henry Jackson Smart, after her mother died, Sonora wanted her father to know how special he was to her．It was her father that made all the parental sacrifices（牺牲） and was, in the eyes of his daughter, a selfless and loving man．Sonora’s father was born in June, so she chose to hold the first Father’s Day celebration in Spikane, Washington on the 19th of June, 1910．
In 1924 President Calvin Coolidge declared the third Sunday in June as Father’s Day．Roses are the Father’s Day flowers: red to be worn for a living father and white if the father has died．
When children can’t visit their fathers or take them out to dinner, they send a greeting card．Traditionally, fathers prefer greeting cards that are not too sentimental（伤感的）．Most greeting cards are too special so fathers laugh when they open them．Some give heartfelt thanks for being there whenever the child need Dad．

A．many people celebrate the day B．only America celebrates the day

A．Sonora honored her father on her father’s birthday

D．her mother died on June 19
3.How many years has passed before Father’s Day became an official day since the father’s day was celebrated?
A．4 B．10 C．14 D．24
