【題目】Don’t be too surprised if you see a car going down the road without a driver in Beijing these days. It might be one of Baidu’s self-driving cars.

Self-driving cars have been in development since 2010, when Google announced that it was making such cars. Since then,companies like Tesla, Uber and Baidu have been working to produce and test their own self-driving cars.

Self-driving cars are expected to change the way we get around. They are safer and more environmentally friendly than usual cars. They can remove the stress of driving and allow disabled or blind people to get around more easily.

But self-driving cars have their own flaws (缺陷)as well. In one test, researchers pointed a laser pointer (激光棒)at the car’s sensors (傳感器)while it was moving. The car mistakenly thought that the laser beam(激光束)was in its way and slowed down or changed direction. Flaws like this could be used by people to trick self-driving cars.

The software (軟件)that is used to direct the cars may not be safe enough. It may crash (崩潰),When we use our computers or smart phones, they sometimes crash without any reason. But if this happened to a self-driving car, the results could be deadly. Improvements to the software could be a way to deal with this problem.

Anyway, whether you like it or not, it’s only a matter of time before they’ll become more affordable and popular on our roads.

1 was the first company to develop self-driving cars?

A. Google.B. TelsaC. Uber.D. Baidu.

2What does Paragraph 3 mainly talk about?

A. Solutions for disabled people.B. Tips for riding in self-driving cars.

3When sensing an obstacle(障礙物)in the road,self-driving cars will .

A. attack it with a laser pointerB. slow down or change direction

C. crash into it to get past itD. stop and move around it

【題目】 When I was a kid in Minnesota, watermelon was expensive. One of my father′s friends, Bernie, was a rich businessman who owned a large store in St. Paul.

Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie′s place. We′d sit on the edge of the dock(碼頭), feet dangling(搖晃), and got ready for a big meal.

Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we′d bury our faces in watermelon, eating only the heart—the reddest, juiciest, firmest, sweetest, most seed-free part—and throw away the rest.

Bernie was my father′s idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie′s wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.

What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don′t take the time to dangle your feet over the dock and enjoy life′s small pleasure, your work is probably hurting your life.

For many years, I forgot that lesson I′d learned as a kid on the loading dock. I was too busy making all the money I could.

Well, I′ve relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That′s the heart of the watermelon. I have learned again to throw the rest away.

1In the second paragraph, the writer and his father were feeling ________.

A. relaxedB. worriedC. hungryD. proud

2In the eyes of the writer′s father, Bernie __________.

A. was just a rich businessmanB. worked hard all the time

C. lived a rich but healthy lifeD. knew how to make money

3The underlined part “the heart of the watermelon” in the last paragraph refers to ____________.

A. the best part of the watermelonB. the writer′s busy life

C. the writer′s decision of making moneyD. the writer′s hope of enjoying life

4What can we learn from the passage?

A. One has to work hard to reach his goal.B. A friend in need is a friend indeed.

C. Watermelon is the healthiest fruit.D. One should keep work-life balance.

【題目】 Many people may enjoy travelling by air, but few like airline food. Airlines have always tried to improve the food quality and the taste in order to attract more travelers. 1 According to some recent scientific researches, a part of the reason is that at high altitude(海拔), we can’t actually taste things well as we do on the ground.

Scientists have found that even before a plane takes off, 2 As the plane climbs, the air pressure changes and our noses become more and more senseless. When the plane goes 35,000 feet high, 3 They help explain why the tomato juice on airplanes tastes far less sour in the air than it does down on the ground.4 Otherwise, the food would be tasteless. Astronauts also have to do with this problem on their journeys for similar reasons.5The studies are going on! We are looking forward to any improvements.

A. the nose no longer knows just like being bitten() by a snake.

B. How to solve this problem?

C. the air inside the plane dries out the nose.

D. Getting something tasty in the air is like a dream to the travelers.

E. It also helps to explain why airlines like to have salty and spicy(辛辣的) food better.
