表建议的情态动词(should、could)
一、 should 表示“应该” （语气较强，更直接）
这是最常用的提建议方式，表示根据常理、责任或情况，做某事是正确、明智或最好的选择。它带有一定
的“劝告”意味。
核心用法与例句：
基于常识或责任提出建议：
You should brush your teeth twice a day. （你应该每天刷两次牙。）
We should respect our teachers. （我们应该尊敬老师。）
基于明确优势或情况提出建议：
It‘s cold outside. You should wear a coat. （外面很冷，你应该穿件外套。）
The movie is great. You should go and see it. （这部电影很棒，你应该去看看。）
给予个人意见或劝告：
I think you should tell her the truth. （我认为你应该告诉她真相。）You shouldn’t stay up too late. It‘s bad for your health. （你不应该熬夜，对健康不好。）
二、 could - 表示“可以” （语气非常委婉、试探）
当你想非常礼貌、不显强硬地提出一个建议或可能性时，就用 could。它意味着“或许可以尝试……”，
给对方充分的选择自由，没有强加的感觉。
核心用法与例句：
委婉地提供一个选项或想法：
If you’re free, we could go for a walk. （如果你有空，我们可以去散散步。）
You could try calling him again. （你可以试试再给他打个电话。）
用于求助或请求建议时的开场：
What could I get for my mum‘s birthday? （我妈妈生日我可以送点什么？）（比用 “should” 更显自己没主
意，更客气）
Where could we have dinner tonight? （今晚我们可以去哪儿吃饭？）
当你不确定自己的建议是否最好时：
A: I need a new computer. （我需要一台新电脑。）
B: You could check out the electronics store online. （你可以去看看那个网上电器商城。）（暗示“这只是个
想法，供你参考”）

题型二 阅读理解
A Smart Diet, a Healthy Life
No matter how old your kids are, you can take steps to improve a healthy diet and to encourage good eating
habits.Family Meals
Family meals are nice for both parents and kids. Children like to guess what they are going to have and parents
get the chance to introduce new foods to children. Parents can also use the mealtime as a chance to talk with their
kids about their life.
Healthy Snacks (零食)
Kids, especially younger ones, will eat mostly what they can get at home. That’s why it’s important to have
enough healthy snacks, such as fruit, vegetables, nuts, yogurt and whole-grain biscuits.
Being a Good Example
The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the lead of the adults
they see every day. By eating fruit and vegetables and avoiding fast food and sweet drinks, you are sending the right
message.
No Shouts about Food
Parents might find themselves shouting at children to get them to have healthy foods in front of them. This in
fact can make children dislike what they are asked to eat. You need to work a bit on different cooking methods (方
式).
Get Kids Included (参与)
Most kids will enjoy making the decision about food. Talk to them about making choices and planning a
healthy meal. It can help them to make good decisions on their own about the foods they want.
1．What is the author’s attitude (态度) towards snacks?

Running is good exercise, but some people often say, “Running is bad for the knees.” They think running will
cause arthritis (关节炎), making them walk with difficulty when they get old. But is that true?
Well, the truth is that running isn’t bad for the knees as long as people do it in the right way. In fact, running
can keep the knees strong and healthy. A study in Medicine and Science in Sports and Exercise found out that runners
had fewer knee problems than walkers. Why? Running helps build up muscles and cartilage (肌肉和软骨) around
the knee joint (关节). Compared with running, walking is easier on the knees. It doesn’t exercise the muscles around
the knees or build up the joint the same way running does.
Another study followed marathon (马拉松) runners before and after their races. The result was pretty
surprising: the runners’ knee cartilage was stronger after the race, and they had a lower chance of developing arthritis
than those who didn’t run at all.
Actually, running itself isn’t bad for our knees, but if we don’t do it right, it can cause problems. Here are the
main things to watch out for. First, run with bad form. Taking too big steps or letting knees bend inward (向内弯曲)
are both bad for the knees. Second, overuse the knees. Running too much, too fast, or without rest can cause knee
problems. Third, run on hard ground. It is bad for the knees, especially if we’ re doing long runs or running very
fast.
But don’t worry. To keep our knees healthy while running, we just need to train smart. Small changes in our
running habits can make a big difference.
