【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Therefore you'll improve your grades, as well as your math skills.
Write it out
You can also check a math problem by writing everything out on paper. Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether your answer is the correct one.
Plug in(代入)
You may find that a variable isn't good enough or have a problem where you have to solve for a variable (变量). This is the only real way to assure yourself that the answer you've found is correct.

If the result of a problem seems to make no sense, it indicates that the answer is incorrect. For example, if you get an answer in the millions and you know it should be in the thousands, you've likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you've got on the first try.
A. Do the opposite.
B. Correct the answers.
C. Plug the variable in the equation (方程) to check it out.
D. Knowing how to go through your math test and checking your work can save you from handing in a test full of mistakes.
E. It also helps you to figure out everything after you have already finished the test.
F. Check for a reasonable answer
G. This helps you to know what information you have and what information you need to solve.

【题目】With the summer holiday just around the corner, it seems like everybody is busy planning their vacations. Here are some tips that can help you enjoy your holiday without emptying your pocket:

Travel off-season

Go to your desired destination while the demand is low and take advantage of huge discounts. During the peak season, the hotel and flight prices increase quickly, and you’ll likely spend more of your vacation time standing in line due to the rush of tourists.1

2

Websites can help you find discount hotel rooms. Look for places that do not charge extra for children if they use the existing bedding. Stay with the locals. If you and your family are going to stay for a longer period, renting a small apartment is a good choice.

Eat like a local

Why eat at big chain restaurants when you can experience something new?3During your family trip, try new food where the locals eat. This will not just save money, but also provide you with a new and different experience. For smaller meals and snacks, avoid restaurants and try street food or other takeout.

Don’t hesitate to bargain

Tourist- heavy places are known for overcharging for just about everything. Clothes, travel goodies, souvenirs, etc. are very expensive at these places.4Bargain hard to get the best price.

Choose local transportation

5Instead, take buses, railways or subways, which are always cheaper. If you are planning to stay for a while, you can consider renting a car. Hiring a car is much easier than carrying your bags everywhere if you are moving around a lot.

A. Save on hotels.

B. Surf the Internet while traveling.

C. Therefore, avoid buying anything there.

D. So it’s best to find out when the off-season starts.

E. Planning your meals is another way to reduce your travel costs.

F. For this reason, you shouldn’t feel ashamed to ask for bargains.

G .As a tourist, avoid taking taxis whenever possible, since they are expensive.

【题目】根据短文内容,选择最佳答案。
Dr. Michael Prager, a leading Botox expert, said that a growing number of women are developing something called “computer face”. He also mentioned that professionals who worked long hours in front of a screen were ending up with saggy jowls(颚骨下垂),“turkey neck” and deep-set wrinkles(皱纹) on their forehead and around their eyes.
The Botox expert said that, of all his clients, office workers were most likely to show premature (过早的)signs of aging. “ If you are one of the unfortunate people who frown(皱眉)while you are concentrating on the screen then, over time, you will inevitably(不可避免地) end up with frown lines.' Dr. Prager said. “What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long. If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck.”
Dr. Prager, who has a practice near Harley Street in London, said he encourages his clients(客户) to put a mirror next to their computer so they can see if they are frowning at the screen. “When people are stressed or thinking hard about something, then they will often put on agrumpy(脾气暴躁的)face' without even knowing what they are doing. When my clients put a mirror next to their desk, they are often shocked by the angry, frowning face which stares back at them.”
He said, “The women I am seeing at the moment have only been using computers at work for the last decade or so. But women in their 20s have grown up with them and use them for every single task. I think the problem is going to become much, much worse. In another ten years, they could be looking quite awful.”
Dr. Prager said there were several simple steps which could avoid “computer face” such as regular screen breaks and stretching the neck muscles. And, of course, there was always Botox. He said that, after a couple of sessions of Botox, the habit of “grumpy face” could be broken.
